Ask HN: What are you working on?

I am working on chartrow.com to visualize financial data in a fun, fast and intuitive way.

One recent addition is the top-performers page which shows the top stocks for a given time period. Example, you can look at the best stocks of the past 10 years (best viewed on desktop):

As a table: https://chartrow.com/top-performers#p=10y

As a multichart: https://chartrow.com/top-performers#p=10y&view=multichart

Heatmap of the top ETFs YTD: https://chartrow.com/top-performers#in=etfs&p=ytd&view=heatm...

I tried to make the screener intuitive and fast: https://chartrow.com/screener#view=charts (drag the sliders and watch the row of charts update quickly)

This visualization shows market breadth (i.e. measures of the statistics of groups of stocks instead of a cap-weighted index): https://chartrow.com/market-breadth#below-high-history

And some cool widgets to the front page: https://chartrow.com/#longer-term

Please comment below what other visualizations would folks want to see so I can add them (and report any data inaccuracy issues too!). TYSM.

I am working on simplified universal rules to define any kind of traffic redirection or asset request redirection or proxy or reverse proxy and so on. The rules are defined, the logic is almost completely written, and now I am writing the test automation cases.

I've been pretty curious to see if I can help reduce LLM hallucinations by giving LLM's more deterministic tools. My current attempt is something like the old StatWing but instead of a GUI, it has an mcp interface for LLM's. A demo, with very limited llm budget and might run out if heavily used, is at https://statimedes.com. I haven't built the GUI to upload a random csv's, but I did load the Telco churn data I found on Kaggle.

I've also experimented with the Brazil purchase data from Olist. That was pretty fun because it has more than on csv. The tool managed pretty well and was able to come to statistically correct conclusions.

FlowCompute is an open-source, cross-platform user interface for OpenFOAM. The goal is to make computational fluid dynamics (CFD) as straightforward as possible.

HNowledge[1], a free iOS app for browsing the HN stories and comments I've upvoted. Made it to fit the way I browse HN, which is upvoting mainly what I find interesting and may want to come back to. The app lets you browse by date, domain or score, add notes and export. Apart from syncing your upvotes from HN, everything stays local without any tracking.

Wanes[2], an Apple Health logging interface for tracking how long symptoms last. I tend to have headaches quite often and the way Apple lets you enter that data is pretty limited, so I created an app which starts a Live Activity for one or more symptoms using widgets, Control Center or Siri. You can change the severity rating while it runs and stop it from wherever you are on your phone (Home Screen, Lock Screen, Dynamic Island, Siri).

Am working on Blackbird Finance, am pretty sure you will understand and relate with the product better if you are from india, so what blackbird does is basically invoicing and tax compliance for global businesses. uh more on what am curious about is that learning about LLM and ai agents that is even what we are trying to implement in blackbird finance aswell. heres our site: https://www.blackbirdfinance.net/

I'm making a browser-based MMO experience of sorts for the 1999 Dreamcast game Shenmue - it's still pretty rough around the edges but people who like the game have liked it so far. The full working storyline mode will be out this week:

I'm also close to finishing an browser-based client for the MMOFPS Planetside:

https://terrasunder.net/play/

I'm getting reports of performance issues for TerraSunder from a couple people so if you run into them, submitting a performance report in the settings would help me a lot!

I have some other cool projects listed on my site here, including a browser-based version of EverQuest that plays itself: https://brynnbateman.com/

EQ project is https://idlequest.net/

I'm working on documentation for zshot[1][2]. Kinda like "what if browser automation had curl-like ergonomics, but also was extremely agent friendly, but also could turn into your headless browser infrastructure". I've been working on it for a while now and have incurred a hell of a debt of "explain what it is and how to do it", so working that debt off bit by bit.

A startup tracker - claude is working between usage limits.

Working on an Apple Notes clone, but everything is a local Markdown file. Currently free, macOS (Silicon + Intel) and Windows. Has tags and priorities, can display many scientific syntaxes (mhchem, most TeX / LaTeX stuff, Excalidraw, PlantUML, Graphviz / DOT, Vega-Lite, and actual Markdown footnotes). Can show notes in vertical lanes like JIRA does. Free iCloud sync too. Still early alpha.

I have been building https://www.accessmrf.com/ to make healthcare price transparency files easy to access to researchers. I index the healthcare pricing files published by more than 180 different insurers in one place, to make them easier to find, and I am developing on ways to make the data even more digestible.

Im working on professional advanced datagrid and Pivot table for React and Js. Many feautures are completely free. try this:

Voiden, an open-source API client where every request is a Markdown file in your repo, with the environment, tests and docs in the same file. It runs locally with no account, works in CI, and agents can run the same requests over MCP. We open-sourced it this year. https://voiden.md/

I've been building Splorbit for about a year (pretty much since Claude got good at coding). The demo is live now for Steam Next Fest! If you like horde survival games like Vampire Survivors and Brotato you will like it. https://splorbit.vercel.app/

I’m building Puggy (https://puggy.dev), a bug recorder made so a coding agent can debug from the recording.

Fiddling and tooling around with AI locally.

I am working on a local developer, analysts tool corekits.dev
