Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 9 Sept 2026We checked that the link to the project still resolves.
- 13 Sept 2026We read the licence text itself (LICENSE). No unusual restrictions were stated.
- 2 Sept 2026We read the project's own documentation and found no sign that development has stopped.

Counted from our own checks: every tool we list is examined against the same criteria.
What it does
Standalone verification for code changes and agent behaviour: it reads the diff for correctness and the conversation for whether the agent stayed on the goal, runnable from a terminal, as an agent skill, or in CI. Bring your own model — no account, no fees, requests go straight to your provider. The reviewer is a model too, so it can inherit the same misreading; treat it as one more gate, not a replacement for tests or a human. AGPL-3.0.

vet FAQ
- Is vet free?
- vet itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
- Do I need to install anything or write code to use vet?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does vet work on a phone?
- No. It needs a computer.
- Can I use vet commercially?
- The licence is AGPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
