Your strategy. Your machine. Your alpha.
Write Python, backtest in your browser. No installs. No uploads. Your strategy code never leaves your machine.
Built for developers who take privacy seriously
No black boxes. No vendor lock-in. Just your code and your results.
Browser execution via Pyodide
Your Python strategy runs entirely in the browser using WebAssembly. Zero server contact. Zero data exposure. Pure local compute.
Encrypted cloud compute
When you opt into cloud acceleration, all payloads are end-to-end encrypted. We process ciphertext — we never see your logic.
