Securie for Next.js
Securie reviews every Next.js pull request and every Vercel deploy, proves the bug with a working exploit, and writes the fix. Broken-access-control, leaked secrets, and Supabase RLS — all covered on day one.
Why it matters for Next.js
Install in one click on the Vercel Marketplace or as a GitHub App. Securie runs on every pull request, gates every deploy, and posts a one-tap auto-fix as a PR comment when it finds a real bug in your Next.js application.
- Designed for the Next.js App Router and Route Handlers
- Zero config — works out of the box with Next.js 14 and 15
- Blocks unsafe deploys at the Vercel gate, not just at the PR
- Sandbox-verified exploit proofs before any finding is shown
Common bugs we catch in Next.js
Broken access control on API routes
Route handlers that accept an object ID and return the object without verifying ownership. Securie's BOLA specialist catches this before merge.
Read the guide →Leaked API keys via NEXT_PUBLIC_*
Secrets accidentally prefixed with NEXT_PUBLIC_ ship to the client bundle. Securie detects and proposes rotation automatically.
Read the guide →Middleware auth that silently fails
Next.js middleware that returns next() on error paths, letting unauthenticated requests through. Securie models middleware intent and flags silent bypass.
Server-action authorization gaps
Server Actions invoked without verifying the session. Classic vibe-coded mistake; Securie traces the call graph and requires explicit authorization.
