PulseDev vs Onlook.A design canvas, or your browser.

Open-source, visual-first code editor for designers, focused on Next.js and Tailwind. Here is how it lines up with PulseDev, using each product’s own docs.

Checked October 2026 against Onlook’s own site and docs.

What is Onlook?

Onlook calls itself an open-source, visual-first code editor where designers work in code. It maps DOM elements back to source so visual edits are written to your code, and it has an AI chat. Work is handed to developers as a branch to review and merge.

Onlook’s website and GitHub README describe the product slightly differently (form factor and AI providers). We list what each source says.

PulseDev is a macOS desktop app. It runs a small server on your machine for each project, a widget on your dev site, and the coding agent CLI you already use. You click an element and describe the fix. In review mode, PulseDev asks the agent to propose changes rather than edit files, and applies those proposed changes when you click Approve.

How it worksClick an element on your running site and describe the fix. The app sends the element’s selector, markup, styles, console errors, failed requests and a screenshot to your agent, which edits the source.Your app renders on Onlook’s canvas. Onlook instruments the code to map elements to source, so visual edits and AI chat changes are written back to files.

When should you pick Onlook, and when PulseDev?

Onlook is a design tool: a canvas where designers drag, style and tweak, with code as the output. PulseDev is for the person who already has the site running and wants their agent to fix what they point at, in their own browser, with any stack. If your team’s designers want to edit Next.js and Tailwind visually, Onlook is aimed squarely at them.

Onlook is the better fit if

  • Designers on your team want to edit layouts and styles directly on a canvas.
  • Your project is Next.js with Tailwind.
  • You want open source and design-token management.

PulseDev is the better fit if

  • You want to stay in your own browser and dev server, on any stack.
  • You want to send a plain-language fix to the agent CLI you already use.
  • You want to review each proposed diff on the page.

Worth knowing: PulseDev runs on macOS only for now (Windows is coming), and it has no visual canvas or design-token editing. It is a way to point at a running page and hand the fix to your agent.
