Our leaky sample app, read in one pass.

Who it's for

Agentic coding is the new coding. You direct the agents; they write and ship apps that do real things: sign people in, take money, store data. The old review step is gone, so Seatbelt is the read that no longer happens, as fast as your fleet ships and built into your daily workflow.

“Nearly half of all AI-generated code contains security vulnerabilities. Developers might catch these. Consumers won't.”
Justine Moore, a16z, Feb 3 2026, citing Veracode. Most people can't vibe code

Seatbelt is the check for that second half: a static read of your repo at git push, and a verifiable report that your fleet shipped securely.

The security read that keeps running.

On your cadence, across the hosts you forgot you had.
