Connect Your Repository
One-click official GitHub App connection
Set up in under a minute with official GitHub App. No servers, no YAML.
Think of GitCaptain like adding an experienced senior engineer into your team’s code reviews. Authorize the official GitHub App with a single click. You choose whether to protect your entire organization or test on just one specific repository.
Developer Opens a PR
Automated GitHub webhook notification
No commands to run. GitHub triggers the review automatically.
Whenever anyone creates or updates a Pull Request, GitHub securely notifies GitCaptain. Only the changed code diff is sent, your full commit history, issues, and main branches remain completely untouched.
Isolated RAM Analysis
Zero-persistence Linux RAM sandbox
Runs purely in volatile RAM. 0 bytes written to hard drive.
A secure worker spins up in temporary Linux RAM. It analyzes grammatical syntax structures (not just plain text lines) and queries your own private AI API key (BYOK). Your proprietary code is never stored on disk and never used to train public AI models.
Instant GitHub Feedback
Inline suggestions & immediate RAM purge
Clear review comments in GitHub. Memory wiped instantly.
Helpful, line-by-line comments with one-click fix buttons appear directly inside your GitHub Pull Request. The moment the review is dispatched, the temporary Linux RAM worker is unmounted and wiped clean, leaving zero trace.
Connect Your Repository in Under Two Minutes
Free forever with your own API keys. Keep your code private, secure, and syntax-verified on every pull request.
