Turn localhost feedback into one AI-ready prompt.

Comment on your dev site and LoopBack captures the screenshot, screen size, URL and element selector, then hands Claude Code a ready-to-fix todo list. Stop sending bugs one by one.

HOW IT WORKS

From localhost comment to AI-ready prompt

Leave feedback right on the page, let LoopBack capture the context, and hand the whole list to your AI agent in one paste.

01

Comment on the page

Drop comments directly on your site running in dev mode on localhost.

02

Auto-capture context

Each note grabs a screenshot, viewport & screen size, URL and element selector.

03

Copy as one prompt

Your todo-list becomes a single, ready-to-paste prompt for any AI agent.

04

Paste & retest

Drop it into Claude Code, fix everything in one pass, then retest each item.

FEATURES

Everything you need to close the loop

Pixel-precise selectors

Every pin carries a robust CSS selector so your AI knows exactly which element to touch.

Auto screenshots

Full-element captures saved to disk with absolute paths, ready to attach to any prompt.

Projects, not ports

Group feedback by project even when three apps share localhost:3000.

AI-ready prompts

One click turns a queue of bugs into a clean, structured todo list for Claude Code.

Retest workflows

Track progress per project with a verify / reopen loop and a live progress bar.

Built for teams

Share workspaces, assign roles, and manage licenses from one dashboard.

We cut our QA-to-fix time in half. LoopBack prompts drop straight into Claude Code and just work.
Marina AlvesFrontend Lead, Visionfarma
The selector capture is magic. No more 'which button?' back-and-forth with the team.
Tiago SouzaIndie hacker
One prompt with ten issues, screenshots attached. This is how QA should have always worked.
