About
About PulseDev.A small Mac app from London.
PulseDev is made by FelixWeb, a London studio that builds Mac apps. It is operated by Felix Web Solutions Ltd.
Why does PulseDev exist?
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.
That is still the whole idea. PulseDev puts the feedback on the element itself, with the selector and page attached, to help the agent find the right file. It runs the agent you already use, on your own machine, and asks for a proposed diff in review mode. You review and apply the proposal in the widget.
The first version shipped on April 13, 2026: the macOS app, the local annotation server and the widget. Every release since is in the changelog.
