What is slicer.dev?

slicer.dev is a code modifier tool. Slicer is a Chrome extension that captures any component from a live website, keeping styles, animations, and interactions, and exports it as an AI-ready prompt or React code for tools like Cursor, Claude Code, Lovable, Bolt, or v0.

Slicer is a browser extension that turns components from live websites into structured prompts or React code you can paste into an AI coding tool. Instead of screenshotting a hero section, describing it in text, and then fixing the CSS that the model guessed wrong, you open Slicer on the page, hover the element you want, and click to capture it. Styles, animations, hover states, and interactions come along with the capture rather than being flattened into an image or a pile of messy HTML. The tool pulls a clean, component-shaped output. You can take it as an AI-ready prompt and drop it into Claude Code, Cursor, Lovable, Bolt, or v0, or take it as a React component. A second surface called Canvas lets you combine several slices, apply your own brand style, debrand a captured component, generate variants, and rearrange things visually before exporting. Slicer also produces UX audits, which distinguishes it from pure copy-paste tooling. The realistic audience is frontend engineers and product designers who regularly trawl competitor sites for patterns, plus agencies building several client sites a month and founders assembling an MVP. The pitch is handoff speed: the vendor claims the usual screenshot-and-iterate loop takes about 47 minutes and a Slicer capture takes roughly 30 seconds, a comparison that should be read as marketing rather than a measured benchmark. Against alternatives, Slicer sits between a visual reference tool and a code generator. It is not a website builder, and it does not write your app for you; it produces the input that your coding agent consumes. The extension is installed through the Chrome Web Store, where the listing shows a 5.0 rating and over 2,000 slices extracted. A free starting point and a 14-day money-back guarantee are mentioned on the site, but no subscription price is published on the homepage, so cost has to be confirmed at checkout.

  1. 1Install the Slicer extension
    Add Slicer from the Chrome Web Store and sign in with Google to activate it. The icon then appears in your browser toolbar on any page you visit.

  2. 2Open a site and select a component
    Browse to the page holding the pattern you want, launch Slicer, and hover the page. Buttons, heroes, pricing tables, and navbars become selectable; click the one you want to capture.
  3. 3Copy the slice
    A single click copies the component with its styles, animations, states, and interactions attached. Nothing needs to be described in text.
  4. 4Remix it on Canvas
    Open Canvas to merge slices, apply your brand style, neutralise someone else's branding, or generate new variants before you commit to an export.

  5. 5Export and paste into your agent
    Choose a prompt or a React component, then paste it into Cursor, Claude Code, Lovable, Bolt, or v0. The output is already structured for the model to consume.
  6. 6Browse the slice library for starting points
    The community library holds components other users have extracted, useful when you want a reference without hunting for a source site first.

Pros and cons

Pros

  • Captures hover states, CSS animations, and interactions instead of flattening a component into a screenshotAI
  • Output is structured for AI builders rather than raw HTML, which reduces cleanup after pastingAI
  • Canvas adds rebranding, debranding, and variant generation before exportAI
  • Works with the coding agents teams already use, including Cursor, Claude Code, Lovable, Bolt, and v0AI
  • Extracted output can be taken as a prompt or as a React component, giving two consumption pathsAI

Cons

  • No subscription price is published on the homepage, so total cost is unclear until checkoutAI
  • Chrome extension only, which excludes Firefox users and any non-browser workflowAI
  • Capturing from third party sites raises licensing and originality questions that the page does not addressAI
  • The 47 minute versus 30 second comparison is the vendor's own figure with no published methodologyAI
  • Designs still need adaptation for real data, accessibility, and breakpoints, so the capture is a starting point rather than production codeAI
