// regression testing for SaaS

## Regression testing that keeps up with your release cadence.

Stop spending a day a week clicking through your own app. AegisRunner crawls every page, writes Playwright tests, runs them on every deploy, and auto-heals the suite when your UI shifts.

// the problem

## What "regression testing" usually looks like in a fast-moving SaaS team.

### Manual regression takes a full day

Every release means 4–8 hours of click-through QA. Bugs slip when the team is tired or rushed.

### Hand-written E2E tests rot

Class names change, layouts shift, selectors break. The suite goes red on green builds; everyone stops trusting it.

### No coverage of the long tail

You test the checkout, you test the sign-up. The 200 other pages that subtly broke last Thursday? Nobody caught it.

### QA hires don't scale

One person can keep ~30–50 hand-authored Playwright tests green. Past that, maintenance overruns new test creation.

// our take

## A regression suite that writes and maintains itself.

### Crawls every page from a URL

No sitemap needed. We walk every link, every form, every modal — including auth-gated pages once you give us a login.

### Generates Playwright tests in minutes

AI grounds tests in your actual DOM, picks resilient role/text/data-testid locators, exports clean TypeScript.

### Auto-heals on UI drift

When a button gets renamed or moved, AI repairs the selector and re-runs the test before paging anyone.

### Runs on every deploy

Webhooks from Vercel / Netlify / GitLab fire the suite the moment your release lands. CI integration on every paid plan.

### Pages you only when something is broken

Slack / Discord / Jira / GitHub Issues with screenshots, locators, and Playwright trace attached.

### Bundles a11y / SEO / security audits

Every scan also runs axe-core (WCAG 2.1 AA), Lighthouse SEO, and security-header checks. One scan, four signals.

### Covers your mobile app too

Ship an iOS or Android app alongside the web app? Upload the build — AI explores it on a real device, generates the tests, and runs them on the same schedule.

### Cross-platform journeys

One test creates a record in the mobile app and verifies it on the website — regression coverage for the sync paths nobody else tests.

## Frequently asked

How is this different from writing Playwright tests by hand?

It's the same engine — AegisRunner runs on Playwright under the hood. The difference is who writes and maintains the tests. With Playwright direct, you assign engineering hours; with AegisRunner, the AI generates, runs, and auto-heals the suite. You can also export the underlying Playwright code on every plan and take it with you.

What about flaky tests?

AI auto-heal repairs locators that drift, and the verification pipeline re-runs every generated test against the live site before saving — so brittle selectors get filtered out before they hit production. Our internal benchmark is < 1% flakiness on a 50-test SPA suite over 10 consecutive runs.

Can we use this on staging behind basic auth?

Yes. Configure a login script (or upload pre-auth cookies) under Project Config → Test Environment. We support form login, OAuth flows, and bypass tokens for WAF-gated staging environments.

How fast does a scan finish for a 100-page SaaS?

Typically 4–8 minutes for the crawl + 1–2 minutes for AI generation. Subsequent re-scans on stable pages use replay-cache and finish in roughly half the time.

Can it regression-test our mobile app as well?

Yes. Upload your .apk or .ipa and AegisRunner explores the app on a real iOS or Android device, generates test cases the same way it does for web, and runs them on real hardware. Cross-platform journeys go further: a single test can act in the mobile app and verify the result on the website, catching sync regressions between the two. Mobile testing is included on Pro and above.

## Try it on your SaaS — no card

First scan in under a minute. You get the report, the Playwright suite, and the audit results on the same page.
