Selection methodology and scope
Public source and a verifiable license are required. Source availability does not imply an independent audit or include every commercial component.
The list is organized by distinct research and automation roles, then evidence and current operational maturity; it is not a score-only ranking.
Category risks
Public code can contain exploitable defects, unsafe defaults and vulnerable dependencies. Users must secure and update their deployments.

Meaningful product differences
Engineering and research depthNautilusTrader provides a Rust/Python event-driven engine across backtest and live adapters. Freqtrade and Jesse center Python strategy research, while Superalgos exposes a broader visual research environment. These are not equivalent setup experiences.
Market making and focused automationHummingbot is strongest as connector-rich market-making infrastructure. Passivbot is narrower and futures-oriented. OctoBot provides a more visual path and an optional managed deployment alongside its public code.
Licensing boundariesOpen-source status applies to the licensed repository scope. Jesse has a commercial live boundary, and optional hosted services can add proprietary components even when a core is public.
Security and maintenanceLocal credentials and inspectable code reduce some provider dependencies while transferring host hardening, updates, dependency review, monitoring and key recovery to the user.
Editorial conclusion
Hummingbot, Freqtrade, Jesse, OctoBot, Passivbot, Superalgos and NautilusTrader expose different strategy, license and operating models. Gainium is excluded because its Community Edition is source-available under a restricted license rather than conventional open source.
