I built an open-source financial research agent that runs in your browser

I’ve been building OpenCandle to help me pull market research together without asking a model to make the investment decision for me.

The web version runs inside your browser, so there’s nothing to install, no account, and no server storing your research or API keys.

You do need to connect your own OpenAI, Anthropic, or Google API key, and set up a few free data providers like Alpha Vantage or Finnhub for it to be even more useful. The local version unlocks a few more data providers that's not possible to run in the web.

It’s free and open source. I use it every day, but it’s still early and I’d really like feedback from people who do their own research.
