production-safety audits for vibe-coded software

Built it fast with AI.
Is it safe to ship?

Paste a GitHub repo. fis reads the code — not skims it — across 13 dimensions of security, privacy, reliability, and AI-generated-code risk, then hands you a clear verdict and a fix for every issue.

Every audit ends in one of four verdicts

Production Ready

Ship it.

Ready with Conditions

A short list stands between you and ship.

High Risk

Real problems — fix before users arrive.

Not Safe

Do not ship. Here's exactly why.

How it works

01

Snapshot

fis pulls a high-priority slice of your repo — source, config, manifests, CI — straight from GitHub.

02

Scan

Deterministic scanners flag hardcoded secrets and dependency CVEs as hard evidence.

03

Reason

Claude Opus reasons across 13 dimensions with extended thinking — semantic analysis, not pattern matching.

04

Verdict

You get five component scores, every issue with a fix and effort estimate, and a clear ship / don't-ship verdict.

13 dimensions, one priority framework

Linters check syntax. fis reasons about whether your software survives contact with production.

Why fis, not a linter

Reasoning, not regex

Claude Opus 4.8 with extended thinking reads architecture, error handling, and intent — catching the AI-generated anti-patterns a linter can't see.

Evidence on every finding

20–80+ issues, each with the offending code, business impact, root cause, and a remediation effort estimate. No vague advice.

Hard guardrails

Deterministic secret and CVE scanners ground the verdict in facts before any reasoning — the score can't hand-wave past a leaked key.

Shareable reports

Every audit becomes a link you can send to your team, your client, or your future self.

Find out before your users do.
