AI App Builder

Code reviews for Windsurf-built apps

Windsurf (Codeium) is an AI IDE with agent-mode editing. The output is normal source code, so the audit focus is the same as Cursor: validation, edge cases, and architecture quality.

Top issues we find auditing Windsurf apps

Patterns documented in primary-source security research, community forums, and real-world audits. These are the things that ship to production and break in front of users.

Cascade agent stalls on long-running tasks

Plan shows, then the spinner spins forever because the response timed out but the UI doesn't recover.

Files >300–500 lines mishandled

Cascade truncates context on large files, producing incomplete edits.

Crashes during background indexing and Turbo Mode

Repeated stability issues per the Windsurf changelog and Trustpilot reviews.

Cascade can't see terminal output

Acknowledged in changelog fixes. Debugging gets stuck because the agent doesn't see what failed.

Wasted credits on failed runs

Trustpilot 1-star reviews dominated by credits charged for runs that never completed.

Same code-quality issues as other agent IDEs

Missing input validation, hallucinated APIs, inconsistent style — common to all agent-mode IDEs.

Cost & performance gotchas

  • Credit consumption on failed Cascade runs is the dominant complaint. No 'attempt-was-billable' refund mechanism.

Comparing Windsurf to other tools

Frequently asked questions

Why does Windsurf burn credits on failed runs?
Cascade charges for the attempt, not the result. Long runs that stall on a single bad plan can rack up credits without delivering any code. We help teams adjust prompting and scope to reduce burn.
