Free, open source, self-hosted.
There's no installer or .exe to download. Forven is AGPL-3.0 open source — you clone the repository and run it entirely on your own machine. Every feature is free; bring your own keys for the optional agent layer.
You need Python 3.11+, Node.js, and git. Nothing is uploaded to Forven — your strategies, data, and keys stay on your machine. See the Quickstart for the path from a fresh clone to your first paper strategy.
Clone the repo
git clone https://github.com/judder659/forven.git, then cd forven. Everything runs from the repository root — no account or sign-in.
Run the launcher
start_all.ps1 on Windows, start_all.sh on macOS/Linux. It builds the backend and frontend, initializes the local database, and starts the stack.
Open the lab
Visit http://127.0.0.1:5173 in your browser. Seed market data is already loaded, so the charts and leaderboard aren't empty. That's it.
Windows, macOS, and Linux.
Because Forven runs from source, it works anywhere the stack runs. The launcher scripts cover Windows (start_all.ps1) and macOS/Linux (start_all.sh). See Install and Running from source for the details.
