Adversarial review

Dedicated reviewer agent that actually challenges the changes, finds issues and demands fixes — just like a senior developer.

!Gemini found an issue

The webhook signature validation is missing a timestamp tolerance. This could be a security risk. Please add a 5 minute window and update the tests.

Frequently Asked Questions

Questions Builders Ask Us

Everything you need to know about local-first multi-agent loops, zero API overhead, and the free beta.

Do I need to pay for extra AI API tokens or wrapper credits?
No. Most developers already pay for monthly subscriptions (like ChatGPT Plus/Pro, Claude Pro/Team, GitHub Copilot, or Google AI Studio) that include generous daily quotas. Traditional wrapper tools force you to connect separate paid API cards with metered per-token billing that runs into hundreds of dollars. Zenborg connects directly to your existing desktop CLI accounts, unlocking the high-volume allowances you already own with zero per-token markups or surprise API bills.
Where does my source code go?
Nowhere. Zenborg is 100% local-first. It operates inside isolated git worktree directories directly on your Mac or Windows machine. Your code, keys, and prompts never touch Zenborg servers.
How does the multi-agent review actually catch bugs?
Zenborg runs an automated review loop: one model acts as the Planner, another builds the implementation in an isolated copy of your project, and an adversarial reviewer model inspects the diff against your goal - demanding fixes and self-healing patches before presenting you with the finished result.
What happens when the Beta ends?
Nothing is charged automatically. There are no surprise fees and no credit card is ever required. Your local projects, git worktrees, and data remain 100% on your machine. Beta testers are recognized as Founding Users and will receive exclusive grandfathered benefits when the commercial release arrives.
How quickly do I get started?
