Show HN: Minigraf – An embedded, bi-temporal graph database in Rust
A
A successor project to my previous attempt at building a temporal graph database ( https://news.ycombinator.com/item?id=23455516). This one builds on its predecessor's concept, but drops the dependency on another database to provide the storage, transaction and query engines. Minigraf is self-contained, packaged as a library crate, embeds into your application, and supports full bi-temporality.

Show HN: OpenChart – OSS TradingView alternative with your own AI agent
A
Hi HN, I'm Weilun, cofounder of OpenChart. We built OpenChart because we wanted Claude and Codex to interface with the markets, like most of humans do, through charts rather than through CLIs. With your existing AI plans, your agent can work directly with your charts: annotate a setup, write an indicator, investigate a market move, or create an alert. The chart, conversation, and research live in the same workspace. OpenChart alerts on any market move: draw any shape on a chart and attach an alert. When price crosses it, the alert triggers your agent to investigate the move and save the research in your workspace. The agents can work with charts, indicators, and alerts. Custom indicators and alert conditions are written in [Tea]( https://github.com/longsurf-ai/tea), a programming language we built for the markets. We believe software shouldn’t impose artificial friction on your workflow. OpenChart is built on that belief with no software cap. The source code is publicly available, and you can use free market data from day one. We also offer optional paid cloud market data for lower latency. Everything is private. Your charts, research, and indicator code are stored on your own computer, with the app's backend running locally too. We currently support only macOS on Apple Silicon, but we're expanding to more platforms. Website: https://openchart.co/ Download: https://downloads.longsurf.ai/openchart/darwin/arm64/OpenCha... We built OpenChart because we want to explore how assets can be co-manages by agents and humans. I'd especially like to hear how you are using agents to help with your investment journey. If you like what we're building, a star on GitHub would mean a lot to us: https://github.com/longsurf-ai/openchart

Show HN: Strata – an expressive semantic layer that can say no to your LLM
A
Hello HN, I'm Ajo and I built Strata. I spent 4 years at Netflix solving self service for non-technical business users. I think I cracked it with my unique approach to semantic layer design. The key challenge is balancing expressiveness with ease of use for our non technical colleagues. It just so happens that focus made it work pretty well with LLMs too. Strata is a full stack solution. It includes a semantic layer, dashboards, subscriptions, and google sheets exports. All of it can be done view agent conversation or via MCP. Some key concepts and features: - Names are strict. Only one thing called Revenue can exist in a project. If revenue is mapped to multiple tables, the query grain plus speed will decide table. - Strict naming conventions lends itself to enabling Automatic data blending acrros fact domains. - Partition and Aggregate aware semantic routing. This allows you to load a portion of your data into a faster compute engine like Druid or ClickHose, while keeping full history in trino or something cheaper. The query engine will choose the faster tier if the query can be resolved there. - Complex measures: out of the box support for snapshot, LOD (include/exclude), Compound, and Auto leveling compound measures. - On top of the semantic layer users can create custom calculations that span fact domains. - Another interesting feature is the ability to create cohorts and apply as filter to an entire query or single measure within a query. We are deliberately not building a semantic layer that your BI tools connect to. I think that is a dead end. We have apis, and mcp for anything custom you want to build on top. Try it free on docker: https://strata.do/try/ Docs here to get you going: https://strata.do/docs/ This is an early beta version. It is NOT open source. However, the free tier includes up to 25 users. You should be able to run it entirely on your machine with docker. I would love to hear your feedback. Especially, those working with Looker and Cube. Thanks for reading!

Show HN: VoidAccess – open-source dark web OSINT, from query to a graph
A
Hi HN! Im Katriel, and im a Security Researcher/Enthusiast and in the wave of AI, i wanted to build that next gen of security tooling that surpasses the current tools, and even the paid industries with an open source engine. I built MailAccess as well, which is going to be the best damn email osint tool out there, in another year. But just before building MailAccess i built VoidAccess, because i was delving a lot into DarkINT and the content inside the dark web is too difficult to navigate through for a human, so i automated that pipeline, made sure the noise was removed, and anything NSFW was filtered out, to give the analyst an overview of what is present in the dark web, without having to actually go through it manually. Very simple to run, you just run a few commands to install, and a couple to investigate. Then the engine takes over, and stops onyl when the job is done(or at a particular time limit, if set by the user). Do check it out, if that is something that interests you. Thanks to the community for giving it the love it has got till now.

Show HN: Things to Do API
A
I built an api/mcp for local events: pop-ups, one-off events, concerts, etc. currently covering the SF bay area. I've been building a bunch of consumer apps lately around personalization and recommendation and have had a hard time finding this data in one spot. agents can find useful stuff through tool calls / web search, but slow. you can scrape on demand too, but i wanted a faster data set and couldn't find an existing provider for the mix of event types I was searching for. the methodology for it is to find influential accounts/posters/etc. and do a fan out across things that they co-post with. mcp: `claude mcp add --transport http thingstodo https://api.thingstodoapi.com/mcp` I'm considering adding other cities. If you're building something that needs local event data, would something like this be useful and where would you want coverage?

Show HN: Scry, programmable internet search w/ congestion pricing
A
Meet Scry, a 500 TB NVMe internet index in ClickHouse that you can run ~arbitrary readonly SQL and some of Datalog over, and I handle the problem of resource-contention with congestion-based micro-auction pricing. When there's capacity, the service is free for non-commercial use. --- Hello. It's 2026, we're training simulated fruit fly brains to play Beat Saber, do we still have to be stuck with internet (re)search as fn: natural language -> black box we can't do anything about -> ranked_list/summary? There is a long history of people trying to do very fancy things that end up being done in relational databases and a little SQL. There is a gravity to them, a bitter lesson, just like scaling of generalized ml training methods. I mean many, many information products can be built off essentially giant real-time OLAP databases and frontier LLMs writing brilliant SQL+Datalog+vector+Jev etc. queries. Google Search, Tavily, Exa essentially have the problem of mapping your agents' context you are willing to provide, to a tiny subset of their index. You pay a fixed cost to an extremely hard problem that has a distribution of hardness, which means YOU eat the downsides when they are running out of budgeted compute to help you out. Their algorithms are opaque to the caller, there's really not much user control, and there's not a serious opportunity to communally improve search recipes, like the lexical+Jev recipes you trust to select bleeding edge AI builders. Furthermore, search companies aren't even pursuing text-to-SQL anymore (several have talked to me)... they made up their minds during the traumatic 2024 text-to-sql days. They were just too early. I hope you enjoy. I'm intent on scaling this paradigm on differentiated hardware over much more data, so any compelling use cases or queries I could show off, would be much appreciated!

Show HN: T0: We trained a 256M SOTA open-weights time-series forecasting model
A
Hi everyone, we are excited to share t0-gamma, the latest model in our t0 family. It is a 256M parameter open-weights foundation model for time series (TSFM). It runs on CPU, GPU or Apple chips. https://huggingface.co/theforecastingcompany/t0-gamma t0 leverages historical data to forecast the likely outcomes over a given horizon. It does so zero-shot. It works on almost any time series, as it can pick up small signals like trends and seasonality. It can also leverage future-known information, like holidays, promotions and weather forecasts. Under the hood, t0 is a transformer that alternates attention between time and across the variates of a series. t0 is agnostic to the domain and to the frequency of the time series. For instance, it can be used to predict retail or electricity demand, as well as server metrics. On European day ahead electricity prices, t0 reduces the error by a third compared with a naive baseline that repeats the previous day. Adding weather forecasts or holiday information improves it even further. There is a Colab notebook to try it. t0 has also been tested independently on electricity prices in Texas (ERCOT). https://colab.research.google.com/github/theforecastingcompa... Like other TSFMs, t0 outperforms classical techniques such as ARIMA, ETS and their variants. On the public benchmarks GIFT-Eval, fev-bench and TIME, t0-gamma currently ranks first among the other TSFMs. It means it is the most accurate model there is to date. Like other TSFMs, t0 can be used inside agentic, routing or ensembling systems. This can improve the scores on the leaderboards even further. Our tech report describes the model family and its evaluation. https://arxiv.org/abs/2609.24559 Trying it takes a few Python lines. pip install "tfc-t0[torch]>=0.6.0" from t0 import T0Forecaster model = T0Forecaster.from_pretrained("theforecastingcompany/t0-gamma").eval() history = ... # history of the time series to predict out = model.predict(history, horizon=24) out.median There is more to come. We are working to extend t0 to joint forecasts across related series and hierarchies, much longer contexts and faster inference. Please give it a try, and don't hesitate to tell us where it works and where it doesn't. We are The Forecasting Company. We want to help companies reduce their uncertainty about the future, so they can make better decisions. We are starting our journey by building foundation models for time series.

Show HN: Reactor Atlas
A
Hi HN, I'm a nuclear engineer and tech entrepreneur. After working for 3 years in the National Atomic Energy Commision (CNEA) in HPC software for nuclear simulations, I co-founded ratherlabs.com, a software company providing blockchain solutions for startups. Rather Labs business reached ~6 million usd in annual revenue in 2024; now demand is decreasing as our niche clients are using AI to launch their MVPs. Now I'm joining my scientific background with my entrepreneurial inclinations to think of problems related to the energy industry. Nuclear is experiencing a renaissance now (it was in a dark age when I was studying after the Fukushima event) so I think this is the right moment for me to jump again into the field. Reactor atlas is an interactive nuclear reactor map and an intelligence layer on top of it. The basic layer indexes: - power reactors - research reactors - fuel facilities with their history and projection, by country. The project is solving a fragmented information ecosystem, where operational and commercial data is hard to conciliate. Also, I'm monitoring nuclear news associated with each of the facilities, political declarations that may affect the nuclear landscape and geo-phisical news (like earthquakes) that could affect operation. On top of the operational + news layer, I'm creating an intelligence layer that will help institutions of different types make faster decisions by subscribing to very specific alerts. As an engineer, I used to code in fortran and c++ when I was working at CNEA, and later I participated in the first Rather Labs projects architecting complex async systems, mostly using MERN stack. I'm no longer coding anymore. I'm focused on designing robust systems with AI agents. I mainly used Claude Fable 5.1 to develop reactoratlas.com, deploying on vercel and using mostly nextjs, threejs, postgreSQL and some cron jobs to query and update data. I miss coding as in the old days, but I haven't code a single line in this project. And I strongly believe we humans shouldn't code anymore: our responsibility is now on designing and supervising AI systems. Thanks for your attention!

Show HN: Chkit – Schema, migrations and backfills for ClickHouse (like Drizzle)
B
Hey HN, im Marc, co-founder of ObsessionDB. We are open sourcing ChKit, our tooling to manage schemas, migrations and backfills for clickhouse. I am a big fan of the type safety drizzle provides for the database. Manage the schema in typescript and generate migrations from it is a powerful workflow. I always wished something like it would exist for clickhouse, so we could manage our analytical workloads the same way. It didn't exist, so we build it. We build it after running ClickHouse at petabyte scale in our previous company, were we managed hundreds of tables, MVs and endpoints reading from them. The way it works: 1. You define your schema in typescript, with typed helpers for tables, mv, column types etc.. 2. You generate the migration, that contains the DDL, to get your clickhouse instance from status quo to what your current typescript schema defines 3. Your CI can check for drift 4. You run the generated migration against production 5. You use the defined types in your code, to ingest your data while making sure it has the correct type. Bonus: if your schema change was BC breaking, we generate the sequence on how to backfill the data, into the intermediate table to migrate (this is quite the hard problem with large tables and schema evolution) In case you have already a clickhouse instance with a schema, you can pull it down and start using ChKit from where you are. Run our generator to setup the boilerplate: npm create chkit@latest If you folks are running clickhouse in production, I am curious to hear what other challenges you are running into.

Show HN: Stoke Money – Personal finance app built around a cash flow forecast
B
Hi HN, I've been through many finance tracking apps, starting with Personal Capital, then Monarch, and most recently Copilot. None of them have worked perfectly for my needs. All of these apps tend to model “cash flow” as the net sum of your transactions during a month, yet while credit card charges are reported immediately, they are typically deducted from checking (cash) accounts the following month when the bill is due. As a result, I've always had to maintain a separate spreadsheet to track my actual cash flow. These apps also have a huge focus on managing budgets, which has never been for me. My spending is rarely consistent month-to-month, so every month I'm comparing my fully justified spending against my budget, and tweaking my budget until I “pass”. So I built yet another finance tracking app. It has the usual components - accounts, transactions, categories - but the core is a cash flow projection engine, and everything else is built around it. Budgets are gone. Instead, each income/spending category is projected forward from your historical activity, but not as a flat monthly number. They land in whatever account you historically use (e.g. checking account for paychecks/rent/bills, credit/debit cards for daily spending). Credit card payments are modeled automatically based on your projected credit card balance. You can set up your own recurring transfers between accounts as well, to model savings, for example. The end result is that the app can forecast how your cash moves, and you can see in advance when any account might run low. If all of your accounts look good for the next 12 months, maybe you don't have a budgeting problem. What’s made the biggest difference for me has been the MCP integration, which I have connected to Claude (but can be connected to any AI agent of your choice). I have asked it to import historical transactions by uploading PDF account statements, categorize/tag all transactions that took place while I was on vacation, and plan transfers across my accounts to cover expected payments. I hope some people that share my frustrations will find this app useful.

Show HN: What 482 hospitals charge vs. what insurers pay, from their own files
C
US hospitals must publish a machine-readable file of their prices, including the rate they've negotiated with each insurer. The files are huge (one is 36GB), in four formats and often messy, so almost nobody reads them. I built a crawler that finds each hospital's official file and pulls out 29 common services. Across 482 hospitals: a moderate ER visit is listed at a median $1,285 while insurers pay $288; a metabolic panel is listed at $207 while insurers pay $11.46. To keep it honest: only per-service fee-schedule dollar rates count (no case rates or percentages, which cover a whole visit), each figure needs at least 3 insurers, and every value is checked against Medicare reference rates. Surgery is excluded because insurer surgery rates cover the whole operation while the list price is one line item. Each hospital page links its source file. Feedback on the methodology is very welcome.

Show HN: SeasonMap – when to travel where? visualized with climate data
C
Author here. I'm trying to visit every country and I've been to 158 so far. Before I decide where to travel, I'd ask a local friend which season to avoid, or open up dozens of browser tabs on climate data to figure out what the place is like in a given month. Climate data still miss things. Cancun in September looks great on paper, with 31°C and 10 hours of sun, but it's hurricane season and the beaches can be covered in seaweed. Typical info that locals would know, which can also be captured as static data. So I built SeasonMap to answer "when should I go to <place>?" What you can do: - Pick a travel style (city walk, beach, hiking, skiing, max sun, low humidity, etc.) and see every place ranked on a map - See what's in season and what to avoid, and why: monsoon, hurricanes, extreme heat, bad air, peak crowds - Filter destinations by temperature, rainfall, sunshine, air quality and hazard seasons - Open a place to see its whole year: month by month weather, events (festivals, whale watching, cherry blossom), crowd levels, practical notes like scams, and traveller anecdotes summarized by AI with links to the sources Data Source & how I made it: - The climate data is ERA5 normals via Open-Meteo (2016–2025), corrected with NOAA station data where available. - Events, hazards and traveller notes were researched and by AI agents, and every one links to its source. Gathering it was easy. Checking it was the hard part. - Yes, I've used AI heavily on this project before anyone call it an AI slop. Making was easy, but it took billons of tokens of beating whack-a-mole ai to polish and tweak to make it usable and decent. Through that, I've created many skills and evals ranging from visual qa, evals for irregular data, automated i18n and others. It still feels much like AI as I was using Claude Design, which i want to improve on. I tried using local llm, but the throughput was so low. Pricing: the first 5 minutes are fully open, no signup. After that, the top 3 destinations and 25 place breakdowns a month are free. A 30-day pass is $7, $39 a year or $69 lifetime. iOS and Android apps are coming soon. Any feedback welcome.

Show HN: Analyst Index – analysts who make money telling you good stock calls
C
Hi HN! What if analyst ratings could be relied on to help you find the next Sandisk, before it takes off? On Analyst Index, analysts publish price targets with a maturity date. Every call gets scored against what the stock actually did, so an analyst builds a record on accuracy instead of on follower count. I started this because after riding the Tesla wave in 2019/2020, I messed up epically with some high risk bets that didn’t work out, including one pick from an analyst I didn’t know was not much good. I needed something like this to help me figure out a) which analysts are worth listening to, and b) which stocks to buy based on their ratings. On what already exists: TipRanks has scored analysts since 2009 and Benzinga sells accuracy scores through an API, so this isn’t entirely new. The difference here is that analyst incentives are aligned with that of investors through a subscription. TipRanks and others scrape published sell side calls and sell access to investors without analysts seeing a dollar of investor revenue. So without aligned incentives, the quality of their work is going to be lower. (Yes, I scraped sell side calls to bootstrap Analyst Index with some data - better than launching with a ghost town). On methodology: Right now scoring is naive. I compare the call against the stock's movement over the stated horizon and score the difference. I thought it better to ship simpler something sooner rather than later. If scoring design is your area, I'd like to talk. What's live: 44 price targets from 25 analysts across 3 tickers, browsable without an account. What isn't: no analyst signup yet, no payments, and no paywall enforcement — anyone can currently subscribe to anyone and see everything. Business model (planned): analysts set their own subscription price, readers subscribe directly, I take 10%. Open problems I don't have answers to: - Cold start on supply. The analysts I want are good and undiscovered, which means they have no audience by definition, so the score has to do the work an audience normally does. If I can't drive demand-side traffic, no amount of scoring sophistication saves this. - Whether price targets carry information at all. Plenty of people think they're noise. My guess is that aligning incentives will produce a signal, but I can't prove that just yet. Regulatory: I operate as a publisher, not an adviser. Content is impersonal and general circulation, with no personalized recommendations and no performance promises. Nothing on the site is investment advice. Link: https://www.analystidx.com/ The feedback I want most is who you would like to see on Analyst Index (analysts) and what it would take for you to become a customer (as an investor). I know most people out of the gate are going to have objections to using Analyst Index for their own investing, but it would be helpful to learn what those objections are to evaluate whether they can be overcome. Any other feedback is welcome too!
