Let non-devs live-edit
existing app UI

Patchlane plugs into ANY app so PMs and designers can reshape screens live directly from the browser.

When the change is ok, fellow co-workers or users like it, Patchlane generates a Pull Request in GitHub with a clean code diff that engineers can review and merge — no new stack, no manual tickets.

• Edit live UI from the browser — change forms, tables and layouts on top of your existing product.
• Generate real code diffs — Patchlane produces focused code patches instead of a new project.
• Safe for teams — engineers stay in control through Git and code review; non-devs never touch the repo.

Under the hood: how it works

Patchlane works by adding a single JavaScript snippet to your app (you can even drop it in via Google Tag Manager). Once it’s there, a PM or other non-technical teammate can open the Chrome extension on any live page, edit the UI directly in the browser — including dynamic elements like tables, product cards or dashboards — and publish those patches so they go live for all users, a percentage of users, or just an internal cohort.

When they’re happy with a change, they click “Create Pull Request” and Patchlane turns the patch into a clean code diff that fits the existing codebase, so developers can review and merge it like any other PR.

This lets non-devs ship real UI changes without setting up the repo or running the app locally, and moves a huge class of “small but painful” tickets out of the bottom of the engineering backlog into the hands of PMs, designers, support and non-technical founders.

Patchlane sits between app generators like Lovable and AI coding tools like Cursor: it’s for teams with an existing product who want non-devs to safely drive UI changes, while engineers stay in control of the codebase.
