VIBEEVAL VS MOBB
Mobb (mobb.ai) takes SAST scanner output (Snyk, Checkmarx, etc.) and generates safe code patches. VibeEval is a scanner that runs your live app and ships fix prompts straight to Cursor.
TL;DR: Mobb is the auto-fix layer on top of your existing AppSec stack. VibeEval is the AppSec stack for vibe coders. If you already have Snyk + need fixes, Mobb fits. If you have nothing and need both, VibeEval is the simpler answer.

Where Mobb Wins
- Reduces SAST triage time by auto-generating safe patches
- Filters out false positives so devs see only real, fixable issues
- Pre-commit hook integration to block insecure changes
- Works with major SAST tools out of the box
Where Mobb Falls Short for Vibe Coders
NOT A SCANNER
Mobb does not find bugs. It fixes findings from your existing scanner. You still need that scanner.
STATIC-ONLY UPSTREAM
Built around SAST. The runtime bugs that take down vibe-coded apps are not visible to upstream tools.
ENTERPRISE-PRICED
Sales-led pricing. Wrong shape for solo founders without an existing AppSec stack.
NO LIVE PROOF
Fixes patterns. Cannot confirm the fix actually closes the exploit on the deployed app.

- You need both detection and fix prompts in one tool
- Your stack uses Supabase or Firebase
- You want to verify the live app, not just patch SAST findings

/ FAQ
COMMON QUESTIONS
01
Does Mobb scan my app?
No. Mobb requires SAST output from another tool (Snyk, Checkmarx, GitHub Advanced Security). It generates the fix; the upstream scanner finds the bug. VibeEval does both layers in one tool.
→
02
What if I already have Snyk?
Mobb is a reasonable add-on that shortens triage. But Snyk + Mobb together still don't run your deployed app. VibeEval covers the runtime layer they both miss.
→
03
Auto-PR fixes — both tools?
Mobb opens PRs with auto-generated patches. VibeEval generates fix prompts you paste into Cursor / Claude Code, which then opens the PR. Different mechanism, same outcome.
