Is Windsurf Safe? Security of Sites Built with Windsurf
Windsurf, like Cursor, is an editor with AI built in — it doesn’t generate AND host the app the way Lovable/Bolt/Replit do. The right question isn’t about the tool, it’s about what happened (or didn’t) to the code after it finished writing.
Quick answer
Same reasoning as Cursor: Windsurf isn’t the source of the risk, it’s the accelerator. Code written fast with AI carries the same old failure classes — just at higher volume, and sometimes with less review, because “the AI already tested it.”
What shows up most
Secret pasted into code by the AI
The same pattern as every code assistant: asking for an API integration frequently results in the key landing straight in the file.
Skipped permission checks
Requested feature = implemented. Implicit access rule (not explicitly requested) = frequently forgotten.
Database configuration is still manual
Supabase RLS or Firebase rules don’t configure themselves — Windsurf writes what’s asked for, and “lock down the database” rarely makes it into the ask from someone who doesn’t know they need to ask for it.
We scan the published site, not the editor
Wherever the site ends up hosted, that’s where Scanfull looks — the editor used to write the code doesn’t change what an outside visitor can reach.
Check yours
Free tools, no signup, aimed at exactly what this guide describes:
Want the full sweep?
These tools check one page and one angle at a time. The full scan crawls every page of your site and, with a verified domain, tests whether the database is actually locked down.
