Build a real backend task with an AI coding platform
Ask it to build an API endpoint with realistic requirements — auth, validation, and a data layer, not a toy example.
BACKEND CAPABILITY SCORE
Backend Arena
Enter what you observed building a backend with an AI coding platform and get a computed backend-capability score.
- Uses your inputs in a transparent calculation
- Instant result with practical next steps
- No signup required
Planning guidance only. Validate important decisions with customer evidence and your delivery team.
YOUR INPUTS

Complete every field. The result updates only when you choose Calculate.
How it works
Record what you found
Correctness issues, security gaps, validation quality, time to a working endpoint, and architecture quality.
Get a weighted capability score
Security gaps are weighted heaviest since backend security failures are the costliest class of defect; speed contributes only a small, capped bonus.

Frequently asked questions
Does Backend Arena test my backend for security issues itself?
No. You review or test the backend yourself (manually or with your own scanner) and enter what you found. Backend Arena computes a score from your inputs — it has no independent access to your code or the platform used to build it.
Why are security gaps weighted so heavily?
A missing auth check or unvalidated input can expose real user data, which is a categorically worse outcome than a slow build or messy file structure. The formula reflects that severity gap deliberately.
Should I trust an AI-built backend for production without review?
No — even a high Backend Arena score reflects your own review at one point in time. Always run a manual or automated security pass before any backend touches real user data.
How is this different from Security Bench Dev?
Backend Arena scores overall backend-building capability (correctness, speed, architecture, plus security). Security Bench Dev is narrower and deeper — it tallies specific vulnerability categories found across any AI-generated code, not just backend tasks.
How We Compare
| Feature | MVPHub | OWASP ZAP | manual API security review checklists |
|---|---|---|---|
| Composite scoring across correctness, security, speed, architecture | Included | Not included | Limited |
| Instant computed score from your review notes | Included | Not included | Included |
| Automated vulnerability scanning of a live API | Not included | Included | Not included |
| Penetration testing | Not included | Limited | Not included |
OWASP ZAP automatically scans a live API for vulnerabilities; a manual checklist has no fixed scoring formula. Backend Arena is a fast, structured composite score for what you've already reviewed — not a substitute for automated security scanning before production.
