WHY WE BUILT IT

Feedback that lands on the element

PulseDev is made by FelixWeb, a London studio building useful apps for everyday Mac life.

Telling a coding agent what’s wrong with a page usually means screenshots and long descriptions. We wanted to click the element, say what it should be and approve the diff, with the agent we already use and nothing leaving the machine.

Made in London
Built and supported by FelixWeb in London.
No PulseDev cloud
Tasks, messages and diffs live as JSON files in ~/PulseDev on your machine.
Your agent, your plan
It calls the Claude Code, Codex, Gemini CLI or OpenCode you already pay for. No extra tokens.

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.

Point at the thing that’s wrong
Turn on Inspect and hover your page. Each element is outlined with its selector and size, so you click the exact button, not a screenshot of it.
Say what it should be
Write the change in plain words next to the element. The selector, page and viewport go along with it, and you choose which agent picks it up.
Review it on the page, then approve
The agent edits your source and the change shows up live. Approve writes it to your files, Reject rolls it back, or reply to iterate.
