Comparisons Snyk
Snyk alternative for Supabase apps
Snyk is a developer security platform. It scans your dependencies for known CVEs, your source for common vulnerability patterns, and your containers and infrastructure-as-code for misconfiguration. It is broad, mature, and it integrates with everything. What it has no concept of is your Supabase project: it will not tell you a table shipped without Row Level Security, it will not tell you a storage bucket is public, and it does not distinguish the anon key that belongs in your client bundle from the service_role key that does not.
Where Snyk wins
These are not the same tool and most teams should not be choosing between them. Snyk covers dependency CVEs, containers and IaC — all three are on the list of things Sentris explicitly says it does not look at. If a vulnerable transitive dependency is what worries you, Snyk is the answer and this page is not trying to talk you out of it.

Choose Snyk if
- Vulnerable dependencies and transitive CVEs are your actual risk.
- You ship containers or Terraform and need those scanned too.
- You are polyglot — Java, Go, Python — not just TypeScript.
- You need license compliance or an audit trail for a SOC 2 process.
- You have a security team who will triage a queue of findings.
Choose Sentris if
- Your database is Supabase and your access control lives in RLS policies.
- You want to know whether a service_role key is in the bundle you deployed — not just whether one is committed.
- You want four checks with a fix under each, not a backlog of several hundred.
- You are one or two people, and a per-developer price for a security team's tool is not the shape of your problem.
- You want to see your exposure count before you pay anything or create an account.
Questions
Can I use Snyk and Sentris together?
Yes, and that is the combination we would pick. They overlap almost nowhere: Snyk covers your dependency tree and your containers, Sentris covers your Supabase access control and what your deployed bundle is handing to visitors. Neither one substitutes for the other.
Does Snyk find a leaked service_role key?
Sometimes, in your repository, if it matches a secret pattern it recognises. What it structurally cannot see is the more common case: a key that is not a literal in your source at all, but reaches the browser through a NEXT_PUBLIC_ environment variable and only exists in the bundle you deployed. Sentris fetches that bundle and reads it.
Is Sentris cheaper than Snyk?
At one or two developers, yes — $19 a month flat against $25 per developer. At fifteen developers the comparison stops meaning anything, because by then you are buying two different things and Snyk's free tier may cover what you needed from it anyway.
One number nobody else on this list publishes
False-positive floods are the standing complaint about this whole category, and not one tool in it states its rate. Ours is precision 1.000, recall 1.000 over 24 planted findings in 9 repositories — with the date, the commit, the scoring rules and the command that reproduces it, plus a paragraph on why 9 repositories is a small corpus. Measured 2026-08-11.
