OpenChart is an open source TradingView alternative with your own AI agent
A new desktop app called OpenChart offers free charting with no software plan limits and lets you plug in your own Claude, Codex or Gemini account to research moves and build alerts.

Why it mattersCharting software with a monthly fee for more panels or more alerts is the kind of tool a small team pays for by habit, and an open source alternative that uses the AI accounts you already have is worth a look.
Many traders and quants pay a monthly fee for TradingView once they want more than two charts in one view, or more than a handful of alerts. OpenChart is an open source desktop app that drops those limits and lets the AI account you already have do the research for you.
OpenChart was published on GitHub by longsurf.ai as a Show HN post this week. The repository, longsurf-ai/openchart, carries 116 stars and 44 Hacker News points at the top of its thread. The desktop app is free and the licence is a modified Apache 2.0.
What the app does
The author's own description: "Add indicators and Volume Profile, then expand to a 4x4 grid. No software plan limits on charts, indicators, or price and indicator alerts." The agent slot is filled by the account the user already has: Claude, Codex or Gemini are named on the project page, and the AI usage is billed by the provider. OpenChart passes the prompts through and does not run its own model.
Four features are called out in the README. A chart grid of up to sixteen panels with indicators and Volume Profile. A plain-language request that the agent turns into Tea monitors, which watch incoming data and fire alerts. An "explain the move" tool that researches a selected chart range and pins source-linked annotations to the bars. A drawing-triggered alert that fires when price crosses a line the user drew.
Tea is a programming language the same team built for market analysis. The README describes it as "functions, loops, state, and collections that evaluate as data flows in", and just install builds the compiler as part of the OpenChart install.
What is free and what is not
The desktop app is free. AI calls follow the plan of the account used to make them. "Optional Cloud market data is priced separately", by the project's own account, and no price is published in the repository.
The licence is a modified Apache 2.0, with a condition that commercial use as a backend service for other applications or as an app development platform for an enterprise needs a commercial licence from the producer. The repository does not call this out as open source in the Open Source Initiative sense; the project's own one-liner is "OSS Tradingview with your own AI".
What is still missing
The download page serves a macOS Apple Silicon disk image only. The development guide covers building from source for other platforms, so a Linux or Windows user has a build step rather than a download. The GitHub organisation longsurf-ai has three public repositories and two followers at the time of writing, so the project is early. The homepage is at chart.chat.
