Your deploy succeeded.
Your app didn't.
Afterlane runs real browser checks against deployed apps to catch blank pages, broken routes, auth loops, and runtime failures before users do.
Deploy succeeded.
Production broken.
CI passes. The build artifact looks fine. The deployment pipeline says green. And then a user opens your app and sees this:
Blank White Screens
A hydration error or missing env variable silently kills your React/Svelte app. HTTP 200. Nothing rendered.
Auth Redirect Loops
Your middleware broke. Every protected route now sends users in infinite circles — and your monitoring shows 0 errors.
Runtime JS Crashes
A bad deploy ships a TypeError that kills the entire page. No uptime monitor catches it. Users just see blank.
Broken API Responses
Your health endpoint returns 200 but the response body changed. Dependent services break silently until a user reports it.
Hydration Failures
SSR/SSG output doesn't match client. React/Svelte throws during hydration. Page appears fine in screenshots but is broken.
Layout Regressions
A CSS change or third-party script shifts your layout. Your product looks broken. A screenshot diff would have caught it.
Simple by design.
Three steps. No SDK. No agent to babysit.
Add routes to monitor
Paste your URLs and define what passing means — page loaded, element visible, no console errors, response shape, screenshot match.
Afterlane runs browser checks after each deploy
We hook into your deploy webhook. After each deployment, Afterlane spins up real Playwright browsers and visits every route — exactly like a user would.
Get alerted before users notice
Discord alerts include screenshots and failure details for the exact route that broke.
Everything you need.
Nothing you don't.
Route Verification
Define any route. Afterlane visits it with a real browser, checks for visible content, and validates your pass/fail criteria.
Screenshot Capture
Full-page screenshots on every check run. Screenshots captured for each route result.
Console Error Detection
Captures all browser console errors, warnings, and uncaught exceptions during page load.
Deploy Integration
Webhook-driven. Trigger checks from GitHub Actions or any CI workflow with a webhook.
Run History
Detailed history for each project.
Discord Alerts
Rich embeds with failed routes, screenshots, and direct links. Delivered to your #deployments channel instantly.
Deployment platforms verify builds.
Afterlane verifies user experience.
Uptime monitors check if a server responds. CI checks if code compiles. Neither checks if your app actually works when a user opens it.
Afterlane executes deterministic, real-browser checks against your live deployment. Not synthetic pings. Not API health endpoints. Real Playwright browsers loading real pages and making real assertions about what users actually see.
The result: actionable failures, clear context, and confidence in every deploy.
