Is Cursor safe for production?
Get instant answers about your app's security.
Short Answer
Cursor apps are production-capable, but "safe for production" is a binary dependent on verification: scanned and clean is safe, unscanned is not. The platform layer is fine; the application layer is where the question is actually decided.
Detailed Answer
Production readiness checklist for Cursor
Not a generic checklist — this is what fails in Cursor apps specifically and therefore what production readiness actually requires:
- **Secret Detection** — Scans your codebase for any API keys, tokens, or credentials that should be in environment variables.
2. **Code Security** — Analyzes code patterns for common vulnerabilities like injection, XSS, and insecure dependencies.
3. **Database Security** — Tests your database configuration for proper access controls and security policies.
4. **Security Headers** — Verifies your deployed application has proper HTTP security headers configured.
5. **RLS on every table** — Run `select tablename, rowsecurity from pg_tables where schemaname='public'` — any row with `rowsecurity=false` is a production blocker.
Production blockers (must be resolved before launch)
- Prompt Injection in MCP Servers — Review MCP server sources. Avoid untrusted MCP integrations. Watch for suspicious tool calls.
- Workspace Trust Exploitation — Enable Workspace Trust in settings. Review .cursor/ files before opening projects.
Each item here has been observed to cause data exposure in Cursor apps. Shipping to real users without closing these is not a risk calculation — it's a breach waiting.
Go/no-go signal
Run a VAS scan. Zero critical + zero high findings = go. Any critical = absolute no-go. Any high = case-by-case depending on what data the app touches (a portfolio site ≠ a fintech app). This is a more reliable signal than "does it feel ready?" because feelings don't account for prompt injection in mcp servers.

Expert Perspectives
“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
“It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.”

Can Cursor apps scale for production workloads?
Performance scaling is a different question from security scaling. Cursor's underlying infrastructure (supabase, firebase, postgres) handles substantial traffic. The scaling concern is that security issues compound at scale: a missing Row Level Security (RLS) policies entry exposes 100 records at a small app, 100,000,000 at a large one. Rate-limit gaps at scale become DoS amplifiers. Resolve the findings above before scaling, not after.
Do Cursor apps meet SOC 2 or HIPAA requirements?
Not by default — and the platform's own SOC 2 status doesn't transfer. Compliance is app-level: you need audit logging on sensitive reads/writes, data encryption for PHI/PII fields beyond the default, access reviews, and documented incident response. Cursor apps can meet SOC 2/HIPAA, but Cursor doesn't ship you there — a security scan plus targeted compliance work does.
What's the single most important thing to do before launching a Cursor app?
Run a VAS scan. This single step catches the majority of pre-launch issues in Cursor apps — it's faster than any manual review, produces fixable output, and gives you a go/no-go answer in minutes. Every other pre-launch action (testing flows, reviewing env vars) is downstream of "did the scan pass?"
