A changelog widget and "what's new" panel for SaaS products with one script tag, public page, RSS, reactions and API.
Overview
The Fizlog homepage
Fizlog is a changelog widget for SaaS products that lets teams tell users what shipped. It requires just one script tag to embed and provides both an in-app widget and a hosted public changelog page, so users see updates in two places from a single source. The widget includes features like unread badges, emoji reactions, Slack and Discord alerts, email subscriber notifications, and an optional feedback inbox. Users can export their data as JSON or Markdown at any time with no lock-in.

- One script tag embed with no backend integration
- In-app widget and hosted public changelog page

- Emoji reactions on entries
- Slack and Discord webhook alerts
- Email subscriber notifications
- Optional feedback inbox tab
- GitHub and Linear integration for drafts
- Views and clicks analytics

Buyer questions
Will this slow down my site?
No. The widget loads asynchronously and renders inside an isolated shadow DOM, so it cannot block your page or conflict with your CSS.
How long does setup take?
Setup takes a few minutes. You paste one script tag, write your first entry, and the widget, public changelog page and RSS feed go live immediately with no backend integration or config file needed.
Do you store my customers' personal data?
No. The widget only reads the public changelog entries you write. Read receipts are tracked in each visitor's own browser, not on the servers. The only visitor data stored is what someone chooses to send through the optional feedback form.
Can I cancel anytime?
Yes. Billing is self-serve through Stripe's own portal, accessible with one click from your settings page.
Is there an API?
Yes. The public API (api/entries.php) lets you publish entries programmatically from CI, scripts, or the GitHub/Linear integrations, authenticated with a per-project API key.
