Your agent writes the line. Nobody reads it.
Thousands of lines a day. No review catches the flaw.

A rules file does not fix it.
The rule was in its file, exact. The agent broke it anyway.
Two minutes to install.
One command. It detects every agent on your machine.

Before you install.
Does my code leave my machine?
What you send for analysis does, and it stays in the region you picked at install: Paris for EU customers on SecNumCloud-qualified infrastructure, Iowa for US customers, on our own self-hosted models, never a third-party AI API. The guard decides on your machine, its telemetry carries metadata only (no prompt content, no raw code), findings never cross regions, and your code is never used to train a model.
Which agents does it work with?
The installer wires Claude Code, Cursor, Windsurf, GitHub Copilot and Codex. Any other agent that speaks MCP works in bring-your-own-config mode, including Gemini CLI, Cline, Continue.dev and Zed.
What does the free plan include, and what happens after?
50 AI credits and 10 static scans, with access to the whole platform, no card and no time limit. Run your first scan and we mail you a promo code. When you need more, the Developer plan starts at €19 or $21 a month.
Is this another scanner that floods the agent with alerts?
No. Legacy scanners run on commits and bury you in false positives. VibeDefend runs at agent-time on the diff being written, with reachability and framework awareness, and hands the agent one finding it can act on, with the fix.
Can I read the study before I sign up?
Yes, and you should. The 36-page paper, the 90 transcripts, the blind audits and the six cases where the layer did not deliver are in the public repository linked on this page.
