Trust Signals
Security you can verify at a glance.
Practical protection for developers who move fast and want safer code without cloud dependency.
No API key required
Install and run immediately.
VS Code + Cursor ready
Built for editor-native workflows.
Fast preflight checks
Reliable checks before commit or push.
Safe cleanup with backups
Local snapshots plus quick revert.
The Problem
AI-accelerated coding ships faster but raises leak risk.
One exposed token or risky commit can create expensive incidents. Modern teams need lightweight DevSecOps for developers, not slow process-heavy blockers.
The Solution
Practical preflight security built for daily workflow.
Vibe Owl adds a practical security layer with local scans, preflight checks before commit, push, or deploy, and guided remediation that helps you fix findings quickly.

About
Why I built Vibe Owl
I learned this the hard way: most vibe coders ship code they don't fully understand, and that creates serious security risk fast. One day, I opened my banking app and realized my account had already been compromised — that was the moment this became personal.
Founder Note
Marcel Iseli
I built Vibe Owl after learning this lesson the hard way. Early in the vibe coding wave, I moved fast, skipped key safety checks, and paid for it. Some credentials leaked and my bank account was compromised.
That experience changed how I ship software. I wanted practical security that fits real developer flow: local-first checks, clear warnings, and a reliable preflight gate before code goes online.
Vibe Owl exists to help developers move fast without repeating the same painful mistakes. It is built by someone who has already been through the incident path and now ships with safety by default.
How it works
Step 1
Install in VS Code or Cursor
Add the extension from the marketplace and open your project.
Step 2
Run scan + preflight check
Evaluate secrets, git leak detection signals, dependency risk, and env hygiene before sharing code.
Step 3
Fix quickly, then ship confidently
Use guided remediation and safe cleanup to reduce risk without slowing down delivery.
Why local-first matters
- Your source code stays on your machine.
- No cloud dependency for scans.
- Predictable performance and zero backend scanning cost.
Compatibility
- Editors: VS Code, Cursor, and compatible VS Code-based IDEs
- Languages: broad support for secret scanner patterns
- Platform: local desktop workflows
- Pricing: free today
FAQ
Does Vibe Owl send my code to a server?+
No. Vibe Owl runs scans locally on your machine and is designed around local-first security workflows.
Your source code is analyzed in your local environment so you can run preflight checks before commit, push, or deploy without cloud code processing.
Do I need an API key?+
No API key is required to use Vibe Owl.
You can install and start scanning immediately. Core checks and local workflows are available without external account setup.
Does it work in Cursor?+
Yes. Vibe Owl is built as a VS Code security extension and supports Cursor workflows.
It is designed for VS Code-based editors and practical day-to-day development flow, including scan, preflight, and remediation steps.
Can I undo cleanup changes?+
Yes. Safe cleanup creates local backups and supports quick revert of recent cleanup actions.
Cleanup focuses on low-risk text normalization (line endings, trailing whitespace, and final newline) and keeps rollback simple.
Can I use preflight before staging changes?+
Yes. Preflight can evaluate staged diffs or fall back to working-tree changes.
That lets you run the same safety gate earlier in your workflow, whether changes are already staged or still in your working tree.
