01 / Choose PreFlight when
Release proof is the job.
Teams that need to prove a release, checkout, entitlement, or recovery path—not only receive a website score.

PreFlight versus CheckVibe
CheckVibe and PreFlight both cover public security, SEO, AEO, uptime, and generated-app risks. CheckVibe presents the broader scan-first inventory; PreFlight is designed around the release decision and continues into browser journeys, payment-to-access verification, deploy gates, incidents, and proof history.

02 / Choose CheckVibe when
CheckVibe owns the brief.
Teams that want a broad, fast website/repository health scan with security, SEO, AEO, performance, compliance, and fix prompts in one report.
Capability matrix
Compare the work, not the logo wall.
Decision lensPreFlightCheckVibeWhat should decide it
Public surface
No-signup launch audit with route, headers, secret, SEO, accessibility, and environment comparison evidence.
Public website scan spanning security, SEO, AEO, performance, compliance, accessibility, and email/domain health.
Both start outside-in; compare the exact checks against your stack.
Repository and backend
Connected GitHub, Supabase, provider probes, and project-specific checks feed the same release record.
Optional GitHub and Supabase connected scans extend beyond the public site.
Check the supported repository languages and backend checks you actually need.
Customer journeys
Journey Canary runs browser paths and retains step-level evidence around signup, auth, and critical routes.
The public product page emphasizes scan, fix, AEO, threats, and uptime rather than a release-linked browser journey recorder.
PreFlight is the clearer fit when user-flow proof is a release requirement.
Revenue path
Stripe test-mode checkout follows signed webhook delivery into the expected Supabase entitlement and stores one trace.
Payment secret and configuration checks sit inside the broader scan; the public page does not describe an equivalent payment-to-entitlement trace.
Use PreFlight when paid access is the contract you need to prove.
After deploy
Deploy gates, Vercel watch, monitors, incidents, recovery runs, and evidence timelines share one operating model.
Daily re-scans, score diffs, live threat detection, uptime alerts, and public status pages extend the scan over time.
Choose between a score-monitoring loop and a release/incident proof loop.
Automation
API, MCP, deploy policies, scheduled checks, evidence exports, and operator workflows.
REST API, MCP, scheduled scans, exports, and agent-ready fix prompts are advertised publicly.
Both automate; test which artifacts fit your CI and owner handoff.
The verdict. No fake winner.
Choose CheckVibe when one broad scan and remediation prompts are the center of the workflow. Choose PreFlight when the hard question is whether a real release and customer path completed correctly. Mature teams may use a broad scanner alongside release-specific proof rather than force one tool to do both jobs.
