Point at your site.Approve the fix.

Click any element on your running site and say what’s wrong. Claude Code, Codex, Gemini or OpenCode edits the real source, and nothing touches your files until you approve the diff.

Free to start. Uses the agent plan you already pay for. Runs entirely on your machine.

Bring the agent you already pay for

  • Claude Code
  • Codex
  • Gemini CLI
  • OpenCode

On any site you run locally

  • Vue
  • React
  • Plain HTML

One loop.
Point, describe, approve.

No screenshots pasted into Slack, no ticket that says “the button looks off”. Feedback lands on the element itself, selector and page attached, so the agent opens the right file first time.

  1. 01

    Point at the thing that’s wrong.

    Turn on Inspect and hover your page. PulseDev outlines each element with its selector and size, so you click the exact button, not a screenshot of it.

    Shiftclick to add more elements

  2. 02

    Say what it should be.

    Write the change in plain words, right next to the element. The selector, page and viewport go along with it, and you choose which agent picks it up.

    ⌘↵sends it to your agent

  3. 03

    Review it on the page, then approve.

    The agent edits your source and the change shows up live. Read the diff in the widget: Approve writes it to your files, Reject rolls it back, or reply to iterate.

    Nothing is written until you approve

See every file it touches, while it touches them.

The widget streams the agent’s work beside your page. Stop it mid-run, reply to steer it, or let it finish and review the change.

Live log
Every Read, Edit and command, streamed from the agent as it runs.
Task board
Queued, running, in review, done. Per page or across the whole site.
Heads-up
A sound and a toast when a fix is ready, so you can keep working.

One desktop app for every site you run.

Each project gets its own local server, port and agent. Start or stop them from the sidebar, and keep the full history of what changed and why.

Your browser. Your agent.
Your call on every change.

Editors now preview your site inside their own apps, locked to their own agent. PulseDev works where you already test, with whichever agent you like, and waits for your approval.

Nothing to host.
Nothing leaves your laptop.

PulseDev is a small server on localhost and one script tag. Your agent runs with your own login, in your own folder.

  • No cloud account

    Tasks, messages and diffs live in a SQLite file on your machine.

  • Your agent, your plan

    It calls the Claude Code, Codex or Gemini CLI you already pay for. No extra tokens.

  • Dev only

    Load the script in development. Production never sees it.
