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 walkthroughs 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. Then follow the walkthroughs: download your first market data (Binance needs no key), build a strategy, and run it through the gauntlet.
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.
