Product
The AI coding agent that actually runs your code.
BuildStax lives in your terminal, reads your whole repo, plans changes, writes code, and verifies it — all before you review a single diff.
Terminal-native
Runs in your terminal. No IDE plugins, no browser tabs, no context switching.
Repo-grounded
Reads your entire codebase before writing a line. Changes fit your patterns, not generic templates.
Verifies changes
Runs your tests, linters, and type checker. If it breaks, it fixes it before showing you.
Plans first
Breaks complex tasks into steps, shows you the plan, then executes — no blind edits.
Git-aware
Works on branches, creates commits, opens pull requests. Your workflow, automated.
Multi-model
Routes between 6 AI models based on the task. Cheap models for boilerplate, strong models for logic.
Model routing
BuildStax routes each task to the best model for the job — saving cost on simple work and reserving frontier models for hard reasoning.
