Harness

From issue toworking change.

Harness finds its way through your codebase, implements the change, and runs the checks before handing it back. Use your own API key or supported provider subscription, with full control over the models behind the work.

Context before code

Understand the system. Change what matters. Prove it works.

01<br>Built for the whole change

Harness follows the relevant code paths, edits the right files, and runs the checks. You get a finished change to review, not a code snippet to complete.

02<br>Focus where it matters

Dedicated agents handle code search, coding, research, and review. Each stays focused without filling the main thread with extra detail.

03<br>See how it got there

Every command, file change, and test result stays visible. For difficult work, add a second review before you inspect the result yourself.

04<br>Your models, your choice

Connect your own API keys or supported provider subscriptions. Choose the provider, model, and how deeply it reasons. Use a separate model for the hardest problems.

05<br>Enterprise ready

Connect local or remote clients to a durable server. Long running work survives disconnects, while model access and run history stay under your control.
