VibeLint Alternative: VibeEval vs VibeLint

VibeLint catches insecure AI output at write-time inside your IDE. VibeEval catches the bugs that make it past every static rule - the ones only visible when the app is running.

TL;DR: VibeLint and VibeEval are complementary, not competing. VibeLint blocks bad code before commit; VibeEval verifies the deployed app is actually safe. Most teams need both - but if you can only pick one, pick the one that catches exploits, not just patterns.

Where VibeLint Wins

  • Inline blocking inside Cursor, Claude Code, Windsurf, VS Code via MCP
  • Git pre-commit hook stops insecure commits from landing
  • 25+ language Semgrep coverage
  • Local-first: code never leaves your machine on the free tier

Where VibeLint Falls Short

STATIC ONLY

Scans source code. Does not run the app. Cannot confirm an exploit works.

NO RUNTIME PROOF

Misconfigured RLS, public Supabase buckets, exposed service_role keys returned by APIs - none are visible in source alone.

IDE-LOCKED

Only protects code while it is being written in a supported IDE. Code generated elsewhere or shipped before install is unscanned.

NO IDOR TESTING

Cross-user authorization is a runtime concern. Static lint cannot tell whether `/api/users/:id` returns someone else's profile.

Feature Comparison

Feature VibeLint VibeEval
SAST inside IDE Yes (MCP) No
Pre-commit hook Yes Optional CLI
DAST (live app) No Yes
Authenticated scanning No Yes
IDOR / cross-user No Yes
Supabase RLS live probe No Yes
Dependency CVE check Yes Yes
Best when used At code-write time After deploy

When to Pick VibeLint

  • You want a guardrail that prevents bad code from being written at all
  • Your team works in Cursor, Claude Code, Windsurf, or VS Code
  • Compliance requires source-level scanning before commit

When to Pick VibeEval

  • You need to know whether the deployed app is actually exploitable
  • Your stack is Supabase or Firebase
  • You shipped before installing any IDE guardrails
  • You want one number - exploitable or not - not 50 lint warnings

Best Together

Use VibeLint as the prevention layer and VibeEval as the verification layer. Lint catches what AI writes; DAST catches what the app actually exposes.

Common questions

Does VibeLint test my deployed app?
No. VibeLint runs inside the IDE (Cursor, Claude Code, Windsurf, VS Code) via MCP. It scans code before it lands on disk. It does not exercise the deployed app, so runtime issues like broken access control, cross-user data leaks, and Supabase RLS gaps are not in scope.
Can I run both?
Yes - that is the recommended setup. VibeLint as an IDE guardrail, VibeEval as the live app verifier. Most production breaches in vibe-coded apps trace to defaults that are correct in code but wrong at runtime (RLS off, public buckets, exposed service keys returned in responses).
What does VibeLint catch that VibeEval doesn't?
Hard-coded secrets in source, prompt injection paths inside LLM-handling code, and SQL injection patterns that have not been deployed yet. Useful at the moment of generation. VibeEval catches what slipped through and is now reachable from the internet.
