Snyk
SCA and SAST developer security
Free tier + paidCode review, testing & securitysnyk.io
What it is
Developer security platform spanning Snyk Open Source for dependency SCA, Snyk Code for SAST, plus IaC and container scanning. It opens fix pull requests that bump vulnerable transitive dependencies to patched versions, and scans from the IDE, CLI and CI. Billing is per contributing developer, not per repository.
Why it earns a slot
AI agents install whatever package name sounds plausible, including abandoned and vulnerable ones. Snyk names the exact vulnerable transitive dependency and opens the upgrade pull request for you.
Know before you commit
Billing counts contributing developers across every connected repo, so cost climbs with contributor count even when only one project is scanned, and free-tier test caps are low.
Getting started
npm install -g snyk && snyk test

How Snyk sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
