Early access

Know what your software is made of.

Light Squares checks the code you depend on and the builds you ship. Both services publish records that you can verify yourself, so you do not have to take our word for anything.

Dependency Canary

Reviews of crate updates for cargo-vet

We review new versions of crates.io packages and publish the ones that pass as cargo-vet audits. You can import them into your project with two lines of configuration.

Attestable Builds

Builds that prove which source they came from

Your build runs inside an AMD SEV-SNP enclave that we cannot look into. You get back a signed record that links the binary to the exact commit it was built from, and anyone can check it.

If you use a coding agent such as Claude Code or Codex, our skills on GitHub teach it to set up Attestable Builds and to import the Dependency Canary audits for you.

Light Squares is invite-only during early access. You can request access or write to us at hello@lightsquares.dev. You can read more about our work at lightsquares.dev.
