What you gain

✓No per-developer pricing starting at $52/mo per developer
✓Full control over vulnerability scanning without Snyk's cloud
✓No test limits tied to pricing tiers
✓Self-hosted scanning with no dependency on Snyk's vulnerability database

What you give up

△No Snyk Code for AI-powered SAST with real-time IDE feedback
△No Snyk Container for base image scanning with fix recommendations
△No managed Fix PRs with automatic remediation pull requests
△No Snyk's proprietary vulnerability database with exploit maturity data

Switching Cost

Snyk's lock-in is the vulnerability database and the fix automation. The scanning itself is replaceable (many open source scanners exist), but Snyk's proprietary vulnerability research, exploit maturity classifications, and automatic Fix PRs are the premium value. Teams doing basic dependency scanning can switch in a day. Teams relying on Snyk Code (SAST), Container scanning, and the auto-fix PRs should budget a week to set up multiple tools to cover the same surface area. The hidden cost is coverage: Snyk's database includes vulnerabilities not yet in the public NVD, and open source databases may miss issues Snyk catches.

Building Blocks

Snyk is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
