From URL to fix prompt — see how I found and patched real vulnerabilities in my own production app in minutes.
From a URL to a fixed vulnerability — in four steps.
Setup
No repo access required — just paste your live site URL. The crew starts fingerprinting your stack in seconds.

Scan
Scout, Locksmith, Prober, Lookout, and Fixer scan in parallel — flagging exposed keys, broken RLS, missing auth, CORS issues, and bad headers.

Fix
Every finding comes with an AI-ready prompt. Paste it into Cursor, Claude, or Copilot and push the fix straight from your editor.

Chat
Have follow-up questions? Your agents are standing by — they explain findings in plain language and walk you through every fix.

Here's what each one is doing on your scan right now.

Scout is mapping your stack — Supabase, Firebase, or custom.

Locksmith is testing table `orders` for anonymous read access.

Prober is checking every endpoint for missing auth checks.

Lookout is auditing CORS policy for exposed attack surface.

Fixer is turning findings into a paste-ready AI prompt.

No. Mitsumono is a post-production scanner — paste your live URL and the crew works from the deployed site, the client bundle, and your backend's public API. Nothing to install, no GitHub OAuth.
Backend fingerprinting (Supabase/Firebase/custom), Row Level Security and anonymous read access, exposed API keys and secrets in the client bundle, missing auth checks and rate limits, and CORS/security headers.
Most tools just list what's broken. Mitsumono's Fixer turns every finding into a ready-to-paste AI prompt — with an explanation — so you can hand it straight to Cursor, Claude, or Copilot and ship the fix.
Yes. Every check is read-only and non-destructive — we test with anonymous requests the same way a real attacker would, but we never write, modify, or delete your data.
Yes — ask follow-up questions about any finding, request a re-scan after you ship a fix, or have the Fixer walk you through a prompt in plain language.
Scout still fingerprints your backend and runs the checks that apply — auth, rate limits, headers, and CORS work regardless of what's powering your app.
Your app is already live and already exposed. The difference is whether you find out from us, or from an attacker.
