PulseDev for Eleventy.Click it, fix the template.

Click any element in your running Eleventy site and say what’s wrong. Your agent opens the template behind it, and the dev server reload shows the edit before you approve the diff.

Works with every template language.

PulseDev on a running Eleventy site: the Growth plan button is outlined with its selector, and a comment box asks the agent to restyle it.

One minute of setup.
None of it ships.

Paste one tag into _includes/base.njk and start your dev server. Keep the PulseDev app open while you work; it runs the server the widget talks to.

  1. Add

    Paste the script tag.

    Put it in _includes/base.njk, the layout every page shares. Remove the tag, or keep it out of production builds.

    _includes/base.njk
    <!-- just before </body>, dev only -->
<script src="http://localhost:3899/widget.js" data-token="YOUR_TOKEN"></script>
  2. Run

    Start Eleventy as usual.

    The widget shows up in the corner of every page. Click it, then click the element you want changed.

    terminal
    $npx @11ty/eleventy --serve
    ➜Local:http://localhost:8080/
    ➜PulseDev:widget connected

It fits how
Eleventy works.

A click carries more than a selector. The page, the element and its selector go to your agent, which follows them to the right file.
