Snyk alternative for teams that ship every week
Snyk is a good tool, and many teams should keep it. This page is for the ones who are looking for something else: a check that runs on every pull request, catches the logic mistakes behind real incidents, and costs the same whether you have three developers or ten.
Price and focus side by side
| Zelsis | Snyk | |
|---|---|---|
| Paid plan | $19/mo flat per account; team of 10 for $49/mo | Team from $25/mo, up to 10 developers |
| Free plan | Unlimited scans, 3 saved projects, 5 fix prompts / month | 5 projects, 100 Code tests/mo |
| Focus | Logic bugs behind real incidents (auth, payments, caching, database rules), plus secrets, dependencies and CI/CD config, gated on every pull request | Developer security platform |
Snyk figures from their pricing page, October 2026. Prices change; check theirs before you decide.
What Zelsis checks that most security tools do not
Security scanners look for known vulnerability patterns. Zelsis looks for those too, and also for the mistakes that cost money or customers without being a CVE: a checkout that trusts the price sent by the browser, a pay button that charges twice, a page that runs one database query per product, a migration that locks the orders table during a deploy, a cookie banner with no way to refuse. Each finding has the file, the line and a fix you can paste into your AI assistant.
Only rules that have caught a documented flaw, or were reviewed as true positives, can fail the check. Everything else shows up as a warning, so the gate stays quiet enough that nobody turns it off. The benchmark is published with what we miss.
When to stay with Snyk
Stay with Snyk if you want one developer security platform from a large vendor and the per-developer price fits your budget. Zelsis does not try to replace a full security platform.
Choose Zelsis if you mainly want each pull request checked before it merges, across logic, performance, deploy safety, privacy and security, at one flat price per account. Plenty of teams run both: the other tool for its platform, Zelsis as the release check.
How it compares with an AI reviewer
We ran Zelsis and CodeRabbit on the same five pull requests with planted flaws and published every comment. Read the comparison.
