Regress

Tests you write break.
Tests we write adapt.

Sign upHow it works
Hand-written end-to-end suites only check what someone thought to check, and they fail every time the UI moves. Here's how Regress compares, and when to keep what you already have.

A redesign renames Pay to Continue and accidentally drops the email field. Same checkout, two kinds of testing.

Hand-written E2E suite

checkout.spec.ts

  • Open /checkout
  • Click “Pay”
  • See the confirmation
  • Checkout form structure

Red build for a renamed button. The missing email field shipped.

Regress

Checkout happy path

  • Open /checkout
  • Click “Pay”
  • See the confirmation
  • Checkout form structure

Rename healed. Missing email field caught before users saw it.

When to use what

Use Regress for the
things you'd miss

Most teams keep a handful of hand-written tests for the rules that must never change, and let Regress cover everything else.

Regress

Catch the breakages nobody thought to test, on every deploy, with no upkeep.

Your own E2E tests

Pin down exact business rules, like an order total or a permission check.

Screenshot diffs

Review pixel-level design changes when the look matters as much as the function.

Questions

What teams ask before switching

Do I have to delete my Playwright or Cypress tests?

No. Keep the few that pin down exact business rules. Regress covers the rest of the app, including the pages nobody wrote a test for.

What happens when my UI changes on purpose?

Renamed buttons and moved fields are matched again automatically, and the pages that changed get fresh tests. Nobody has to update selectors.

Will it flag every price or date that changes?

No. Data changes like prices, timestamps, row counts and sort order are ignored by design. Alerts are for missing fields, buttons, links and broken flows.

Does it replace visual regression tools?

Not for pixel-perfect design review. Regress compares structure and behaviour, so it won't flag a 2px shift, and it won't miss a checkout that stopped working.
