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 sets up Python and the web UI, initializes the local database, starts the stack, and keeps it running. Prefer a window to a terminal? Open Forven Launcher.vbs. On macOS/Linux, a short setup ends with start_all.sh.
Open the lab
Visit http://127.0.0.1:5173. A setup wizard offers to connect a model provider for the agents — everything else works without one. Download your first market from Data (Binance needs no key) and follow the Quickstart.
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.
