Is your FastAPI app secure?

Built your FastAPI app fast? Ship it without spending another week on security testing. FastAPI is the default Python backend for AI-built apps. It's fast — but generated FastAPI apps routinely ship endpoints with no auth, public docs, and unvalidated input. Opviva is the agent that checks, proves, and fixes your FastAPI app.

Free · no signup · we never store your source code

  • We prove vulnerabilities by reproducing them — not guesses
  • Tamper-evident record of what your AI agents do

Common security gaps in FastAPI apps

Endpoints without auth

Generated routes ship without authentication, so anyone with the URL can read or change your data.

Exposed docs & secrets

Interactive /docs and the OpenAPI schema stay public in production, and secrets surface in config or the client.

Unvalidated input

Handlers trust input, opening injection, SSRF, and broken-access-control risks.

The agent that checks, proves, and fixes your FastAPI app

  • Tell it your app’s URL — the free scan grades your live app 0–100 in seconds, no code access needed.
  • Connect GitHub and it reasons about your repo for deeper, fix-ready findings.
  • It proves each exploit is real on the Evidence Canvas, then opens the fix as a pull request you approve.
  • Turn on 24/7 monitoring and it keeps watching after launch — re-checks and uptime so new issues get caught and closed.

FastAPI security — ask the agent

Is my FastAPI app secure?

Not by default — generated FastAPI apps commonly ship unauthenticated endpoints and public docs. Paste your app's URL into Opviva for a free grade.

How do I secure my FastAPI endpoints?

Opviva proves which endpoints are open and grades your app free, then opens fixes that add authentication and lock down docs.

Can Opviva fix a FastAPI app's security?

Yes — the agent opens reviewed pull requests that add auth, hide docs in production, move secrets server-side, and validate input.

How do I secure my FastAPI app?

Start with a free Opviva scan of your live FastAPI app — it grades you 0–100 and lists exactly what's exposed. Then connect GitHub so Opviva can open reviewed pull requests that move secrets server-side, add access control, and set security headers, and turn on 24/7 monitoring so it keeps watching after launch.

Is it safe to launch a FastAPI app to production?

Not until it's checked. AI-generated apps frequently ship with exposed keys, missing access control, and no security headers. Run Opviva's free scan first (no signup), fix what it finds, and turn on continuous monitoring so new issues are caught automatically.
