Heimdall Scan vs Snyk
Snyk is a mature enterprise platform that covers dependencies, containers, infrastructure-as-code, and SAST. Heimdall Scan focuses on one thing: the application code a vibe coder ships from Cursor, Lovable, or Bolt. Snyk is broader. Heimdall Scan is sharper for the specific job of catching the mistakes AI editors leave behind.
TL;DR
Snyk wins if your main risk is vulnerable dependencies or you need container and IaC scanning under one roof. Snyk's CVE database is among the best in the industry. Heimdall Scan wins if your main risk is the app code itself, especially the auth and access-control bugs AI editors quietly skip. We're free during beta; Snyk gets expensive fast at team scale.
Side by side
Where Snyk is the better fit
Snyk has the broadest scope of anything on this list. If you need one product that covers dependency CVEs, container image scanning, IaC misconfigurations, and SAST across many languages, Snyk does all of that. The dependency database in particular is excellent and well-maintained. If your stack is bigger than just a JavaScript or TypeScript app, or your main worry is a known CVE in a npm package, Snyk is the more complete tool. Their integration with GitHub PRs (auto-commenting on dependency bumps) is also more mature than what we offer today.
Where Heimdall Scan is the better fit
Snyk's headline product is dependency scanning, which finds known CVEs in libraries you imported. That's important, but it's not where AI editors make mistakes. AI editors make mistakes in the code they write for you: a route that forgot the session check, an .env that got committed, a Stripe webhook handler that skipped signature verification, a SQL query that interpolated user input via a template string. Heimdall Scan was built to catch exactly that class of issue, written for an audience that doesn't know what CVSS means. The output is one paragraph of plain English plus a prompt you can paste straight into Cursor or Lovable. Setup is one click. And it's free during beta, which matters because Snyk's paid tiers add up fast once you're past their free quota.
Pricing
Free during open beta. Sign in with GitHub and you get every check at no cost. No card, no per-seat trick, no scan-limit games. We aren't charging yet because the product is in beta. A paid Ultra plan is coming later for high-volume usage.
If your stack is a JS or TS app shipped from an AI editor, and you want to know what's wrong with your own code (not just the npm packages it imports), run a Heimdall Scan. It takes under a minute and it's free during open beta.
