Pentest your vibe-coded app with Strix before attackers do
Strix is an open-source AI pentesting tool. Instead of only scanning code, it actively tests your running app for issues like SQL injection and XSS and tries to prove each one is exploitable.

What they did
Strix is an open-source AI pentesting tool. Instead of only scanning code, it actively tests your running app for issues like SQL injection and XSS and tries to prove each one is exploitable.
Result (as claimed)
Reports come with proof of exploitability, so you can fix real flaws first.
Tools they used
Cost: Claude Code: from $17/mo.
Set it up
Pick a contained repo or task
Start on a branch or side project where mistakes are cheap.
Install and configure
Set up Claude Code. Read what it can run on your machine and limit permissions where possible.
Run it on a real task
Give it a well-scoped issue and let it work. Review the diff like any pull request.
Add guardrails
Keep tests and CI in the loop, and never let an agent push to main or touch production secrets unattended.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like). 2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data. 4. Finish with a checklist to run it again next time.

Related use cases
Audit a vibe-coded app for leaked secrets, missing RLS and dead buttons
Vibe Aegis v2.0 is an open-source safeguard and adversarial audit loop that runs in one command across Claude Code, Codex and Cursor. It targets what agents often ship: exposed NEXT_PUBLIC_ secrets, tables without row-level security, IDOR bugs, client-trusted checkout prices, double-spend race conditions and dead placeholder links.
Vibe-code a shared context layer for your AI agents
In a week he vibe-coded a context layer for agents with shared and private data, tenant-aware retrieval, citations and local embeddings, which you clone and connect to Claude Code.
Have a second AI review your agent-built app as if it must handle 10x the data
The footage search Claude Code built him looked done, until a second AI found every vector held in RAM, 8 to 10 GB at 1,000 hours of footage by Claude's estimate. His review prompt: list each problem as a numbered fix with the file, why and the exact change.
Build a local voice-to-text app with Claude Code
Matt Hartman used Claude Code to research local speech-to-text models on Hugging Face and build Ghost Pepper, an open-source dictation app that runs on your own computer so you do not pay per transcription.
