01What you get

Every check, every guard,one dashboard.

PreFlight scans your payment keys, auth flows, webhook routes, email delivery, deployment health, revenue side-effects, API security, and release gates — all before a new version hits real users.

The full picture

Everything that can break your app. One dashboard.

The launch scan is just the start. The real risk is what happens after deploy — so PreFlight keeps watching, blocking bad releases, and catching revenue drift.

Uptime Monitor

Watches every integration around the clock. When an auth flow stalls or a webhook stops arriving, you hear about it in minutes — not from angry users on Twitter.

Deploy Gates

One API call between your CI and production. If things aren't green, the deploy gets blocked. That simple.

Shadow Checkout

Runs a real Stripe purchase in test mode, traces the webhook into your database, confirms the subscription row landed, then cleans up after itself. Full payment proof without touching real money.

Vercel Watch

Tracks your deployment status and domains even outside release windows. No surprises.

Revenue Watch

Matches Stripe payments against your database rows. Catches silent billing drift before customers notice.

Security Scanner

API key scopes, rate limits, webhook boundaries, and exposed secrets — reviewed in one place.

Runbooks

When something fails, you get the exact steps to fix it. What broke, where to verify, how to confirm the fix. No vague "check your config" nonsense.

Reports & Trust Center

PDF, CSV, JSON exports plus a public trust page backed by real check data. Show investors and customers you take reliability seriously.
