Why Selfloop

Visual QA that keeps up
with how you ship

✓
✓
One agent, every screen

Selfloop drives real user flows across web and mobile, judging each rendered screen the way a person would. Not just the DOM.

Catches what diffs miss

Overflows, overlaps, clipped CTAs, garbled output: the visual breaks pixel diffs sail right past.

From commit to production

Gates every build, then keeps watching live so a broken deploy never reaches your users.

Triage in seconds

Every issue ships with the exact element, an annotated screenshot and the route it broke on: you fix it at a glance instead of hunting for repro steps.

How it works

Three steps to ship
without breaking things

You ship features fast with AI. Selfloop makes sure they actually work: before and after they go live.

01Understand

It learns your app and the flows that matter

Selfloop reads your codebase and maps every screen and core journey: sign-up, checkout, onboarding. So when AI coding ships a new feature fast, Selfloop already knows what must keep working.

02Develop

It clicks through everything while you build

On every change, Selfloop drives your app locally and walks the real flows like a user: you ship without errors and never burn an afternoon manually re-testing the same screens.

On loop, all day: Selfloop drives your app in the simulator, files the bugs it finds, and hands the fix prompts to Claude Code, then re-tests the changes.

Graph memory

State-of-the-art memory. It knows your whole app.

Selfloop builds a living graph of every screen and path in your app, so on every run it knows exactly what changed, what’s covered, and where the bugs live.

Vibe coding is fun. But testing it by clicking through everything SUCKS. That's why we made Selfloop: you ship fast and skip the part that drains you.

testing this by hand · every · single · time
“
Testing our app while we’re building (and making sure we don’t ship embarrassing bugs to the cloud) is such a life saver. We never have to tell it about new features; it just understands our app and codebase.
