Strategy Studio · free · no signup
Build, backtest, and orchestrate — in your browser
A real MuseScript IDE running the same in-browser engine the desktop app ships. Your library lives in this browser; nothing is uploaded. Guided first run.
A library, not a scratchpad
Every strategy is saved in your browser — create, rename, duplicate, delete. Come back and it's all still here.
Three backends, one result
Interpreter, JavaScript, and WebAssembly. Toggle and re-run; interp and JS return byte-identical numbers — the parity gate, live.
Tune from source
Detected params become inputs; changing one rewrites the strategy's default and re-runs — the source stays the single source of truth.
Ensembles
Blend several strategies equal-weight on one tape to see whether a set actually diversifies, or just stacks the same bet.
Default runs use a deterministic, driftless, seeded synthetic tape with no planted edge. Enter a symbol (e.g. AAPL, BTC) to backtest on real public bars — provenance is always labelled honestly. Not investment advice; hypothetical results are not indicative of future performance.
