Reasonix is an open-source coding agent aimed at long, complex software tasks. It ships as a single Go binary under MIT license with desktop Studio, CLI/TUI, browser Web Studio, and editor integration over ACP, emphasizing plan mode, per-tool permissions, workspace sandboxing, and per-turn checkpoints you can audit or revert.
Engineers who want a self-hosted or local coding agent with strong undo, permissions, and multi-surface workflows rather than a black-box autopilot.
Long autonomous runs still depend on your chosen model provider and local machine resources; there is no vendor-hosted pricing page for a managed SaaS tier.
Reasonix targets reliable autonomous coding with readable plans, explicit approvals, and checkpoints so multi-hour agent sessions stay auditable and reversible across CLI, desktop, and browser surfaces.
