What's hiding inyour code?

Paste any public GitHub repo. Fixie reads the code, finds real vulnerabilities, and explains each one in plain English with a suggested fix, so you learn as you secure.

Java · Kotlin · Go · TypeScript · public repos only

How it works

  1. 1

    Paste a public repo

    A GitHub URL or the owner/repo shorthand. That's it.

  2. 2

    AI reads your files

    Java, Kotlin, Go, TypeScript: semantic analysis, not just pattern matching.

  3. 3

    Learn what's wrong

    Plain-English explanations, business impact, and a suggested fix for each finding.

Semantic, not regex

Reads for intent, so it can catch logic bugs a grep can't.

A suggested fix every time

Each finding comes with code you can review, so you learn the fix, not just the flaw.

Zero setup

No install, no config. Paste a repo and go.
