Turn wild AI code into ship-ready projects.
CodeFour is your AI firewall: paste code from any model, run it in a sandbox, scan it for problems, and export a structured project ZIP. No more guessing if AI “got it right this time.”
Built by a small, obsessed team that was tired of AI shipping broken code into production.
What CodeFour checks for:
- ✅ Sandbox validation via Judge0
- ✅ Multi-file project ZIP export
- ✅ Grep-style scans for secrets & dangerous patterns
- ✅ AI “Explain & improve” on failing code
- ✅ Drag & drop file tree with smart placement
Coming up on the roadmap:
- Security/risk scoring per snippet
- One-click test harness generation
- CI integration so bad AI code never hits prod
Validate
Run AI-generated code in a real sandbox, see stdout/stderr, and stop guessing. If it breaks, you see exactly how.
Guard
Scan for secrets, dangerous shell commands, and risky patterns before they ever leave your clipboard.
Ship
Export clean project ZIPs with a sensible file tree so you can drop them straight into your repo.
Why CodeFour exists
This isn't a weekend toy. CodeFour is being built as a lifeline: a way to turn chaotic AI output into stable, shippable code — and to prove that a small team with nothing handed to them can still ship something world-class.
