What else you could use
8 tools overlap with this one: four neighbouring categories and four scanners built for the same people we are. Each page below opens with what that tool does better, because a comparison written by the vendor is worth nothing unless it can lose a row, and two of these are free, already installed, and the right answer for a fair number of readers.
Snyk alternative for Supabase apps
Snyk finds CVEs in your dependencies. It does not know what Row Level Security is. An honest comparison of what each tool covers, and why most Supabase teams end up wanting both.
Read the comparison →Semgrep alternative for Supabase and Next.js
Semgrep is a rule engine you point at your code. Sentris is five focused checks that already know Supabase and the live web response. What each one costs you in setup, and where the pattern-matching model runs out.
Read the comparison →GitHub secret scanning alternative for Supabase apps
GitHub secret scanning catches keys before they land in a commit. It cannot catch the one that was never in a commit: the service_role key your deployed bundle is serving. What each covers.
Read the comparison →Supabase Security Advisor alternative: what it misses
The Supabase advisor is free, built in and correct. It also reads only your running database, which leaves three of the four places these mistakes live unchecked. An honest comparison.
Read the comparison →Vibe App Scanner alternative: URL scanning vs. reading the code
Vibe App Scanner tests your running app from the outside. Sentris reads the repository behind it. An honest comparison of what each model can and cannot see, and which of the two you actually need.
Read the comparison →CheckVibe alternative: breadth of checks vs. depth in one stack
CheckVibe runs over 200 checks across security, SEO and AEO, ships PDF reports and white-labelling. Sentris runs nine and reads your repository. Which shape of tool fits which job.
Read the comparison →SecurityScanner.dev alternative: bundle extraction vs. reading the schema
SecurityScanner.dev is the strongest technical scanner in this category, and it still has to guess your table names out of a JavaScript bundle. Sentris reads them from your migrations. What that difference is worth.
Read the comparison →Lovable security scanner alternative: what the built-in check misses
Lovable ships a pre-publish security scan at no extra cost. Independent researchers found it checks whether security features exist, not whether they work. What that gap looks like in practice.
