Freemium

Best for
Developers seeking high token efficiency for long-horizon coding tasks and those who want a transparent, open-source terminal agent that integrates with the StepFun model ecosystem.
Not ideal for
Users who depend on Claude-exclusive models, those who require strict 'ask-first' security defaults without manual configuration, and developers working in untrusted environments needing OS-level sandboxing.
A powerful and highly efficient alternative to closed-source coding agents that excels in autonomy and transparency, provided the user manually adjusts its default permission settings to ensure adequate security.
The v0.1.6 release (2026-10-23) introduced background subagents, experimental Lark remote connectivity, one-off side questions via /btw, and a session search index. Previous updates (v0.1.4–v0.1.5) added enhanced context management (CLM), a task self-review feature, and a granular usage panel.
