The Problem

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.

No visible content detected
Screenshot captured after page load 200 OK

Auth Redirect Loops

Your middleware broke. Every protected route now sends users in infinite circles — and your monitoring shows 0 errors.

Route never reaches a stable page
Redirect pattern found on protected route 302

Runtime JS Crashes

A bad deploy ships a TypeError that kills the entire page. No uptime monitor catches it. Users just see blank.

Browser exception during render
TypeError captured from the user's page TypeError

Broken API Responses

Your health endpoint returns 200 but the response body changed. Dependent services break silently until a user reports it.

Expected response shape changed
API result failed the configured check API

Hydration Failures

SSR/SSG output doesn't match client. React/Svelte throws during hydration. Page appears fine in screenshots but is broken.

Client render mismatch detected
Console warning captured with screenshot context Hydration

Layout Regressions

A CSS change or third-party script shifts your layout. Your product looks broken. A screenshot diff would have caught it.

Important UI became unreachable
Screenshot shows the blocked interaction Visual
How it Works

Simple by design.

Three steps. No SDK. No agent to babysit.

01

Add routes to monitor

Paste your URLs and define what passing means — page loaded, element visible, no console errors, response shape, screenshot match.

/settings Browser check
/pricing Browser check

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.

Features

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.
