Create your Fizlog project

Sign up (free for one project), create a project and open it. You need two values from the project page: the public key used in the embed snippet and the API key under "API access".

Get your changelog out of Featurebase

Featurebase serves the changelog feed at /api/v1/changelog/feed.rss on your Featurebase domain — e.g. https://yourorg.featurebase.app/api/v1/changelog/feed.rss (there is also an RSS button on the changelog page). Each item carries the full content and a category (New, Improved, Fixed), which the importer maps to Fizlog types.

php fizlog-import.php rss https://YOURORG.featurebase.app/api/v1/changelog/feed.rss

If your changelog is private or on a custom domain, open the changelog page, use its RSS button to get the exact feed URL, and pass that instead.

Preview, then import

Run the importer with --dry-run first to see every entry it found, then run it again without the flag. Entries keep their original dates and are imported silently, so no webhook or subscriber email fires for old posts.

The importer is a single PHP file with no dependencies — download fizlog-import.php or read it on the guides page.

export FIZLOG_API_KEY=your_project_api_key
php fizlog-import.php rss https://YOURORG.featurebase.app/api/v1/changelog/feed.rss --dry-run
php fizlog-import.php rss https://YOURORG.featurebase.app/api/v1/changelog/feed.rss

Swap the embed snippet

Replace the Featurebase widget code in your app with the Fizlog script tag. Without data-selector the widget shows as a small button in the corner; with it, the bell renders inside an element you choose.

BEFORE — Featurebase changelog widget

<!-- Featurebase SDK loader (do.featurebase.app/js/sdk.js) -->
<script>/* ... */</script>
<script>
  Featurebase('init_changelog_widget', { organization: 'yourorg' /* ... */ });
</script>

AFTER — Fizlog

<script src="https://fizlog.com/widget/widget.js"
        data-project="YOUR_PUBLIC_KEY"
        data-selector="#whats-new" async></script>

5

Point old links at your new changelog

Redirect your old Featurebase changelog link (subdomain or custom domain) to your Fizlog public page at fizlog.com/p.php?key=YOUR_PUBLIC_KEY — Fizlog doesn't host custom domains — and update links in your app and docs.

6

Check, then cancel Featurebase

Open your app and the public page, confirm the entries look right, and only then cancel your Featurebase subscription.
