Windsurf security: check your Windsurf-built app before launch
How secure is Windsurf?
Windsurf is an agentic editor, so like Cursor its security is about the code it writes and what you deploy. The recurring issues are committed secrets, endpoints without enforced auth, and Supabase tables without row-level security — all of which still run fine, so they ship.
Windsurf (by Codeium) is an AI editor and agent that builds and edits code in your repo. You own the repo and the deploy, so the finished app is the thing to verify before launch.
The common risks in Windsurf apps
Committed secrets and .env files
Keys and .env files committed during iteration remain in git history even after deletion.
Missing auth on endpoints
Generated routes and actions can ship without enforced authentication.
Supabase RLS off
A scaffolded Supabase backend often starts without row-level security.
Vulnerable dependencies
Generated code can introduce outdated or risky packages.
How to check your Windsurf app
- Confirm .env is git-ignored and no key is committed.
- Check every endpoint enforces auth in code.
- Enable RLS on all Supabase tables and test logged-out access.
- Audit dependencies for known vulnerabilities.
Scan your Windsurf app before you launch
SafeLaunch checks your repo and live site in about 30 seconds and gives you a prompt to paste back into Windsurf to fix each finding.
Windsurf security FAQ
Is a Windsurf app secure?+–
Windsurf writes capable code, but it will generate insecure patterns — committed secrets, missing auth, open databases — unless prevented. Review and scan before launch.
Does Windsurf check security for me?+–
Windsurf helps you write code; it doesn't run an independent audit of the finished app. A pre-launch scan does.
How do I scan a Windsurf app?+–
Run a SafeLaunch scan on the repo and live site to find committed secrets, missing auth, RLS gaps and vulnerable dependencies, each with a fix prompt.
