NautilusTrader
High-performance algorithmic trading platform (Rust core, used from Python) that runs the same strategy code in backtests and live.
Professional-grade engine for people who want the same code in backtests and live trading.
Who it is for
Experienced programmers who want a serious, fast engine with the same code in backtests and live.
Strengths
- Very active project (over 30,000 GitHub stars, daily commits in October 2026).
- Rust core with Python for strategy logic.
- The same strategy code runs in backtests and live, which reduces surprises when going live.
- Around 20 integrations, including Binance, Interactive Brokers, Betfair, Polymarket and Databento.
Good to know
- The README itself warns that live trading can differ from backtests because of venue, network and timing behavior.
- Some integrations are marked "planned" or "building", not stable.
- It is a professional tool: not for learning to code.
- LGPL-3.0 license: if you distribute software that modifies it, you have license obligations.
