Used in production
Real products that tell their users what shipped with Fizlog.
Fizlog is a "what's new" widget for your product — one script tag, a public changelog page, email & Slack notifications, and a free plan that actually works for a pre-revenue SaaS.
Write an update once. Your users see it inside your product a moment later.
Everything you publish shows up in the in-app widget and a hosted public page — write once.
The bell icon in the corner is the entire integration — click it, this is real, running off the same widget your customers would embed.
No roadmaps, no voting boards, no bloat. Just a widget people actually open.
Paste a single line into your app. Under 7 kB compressed, no cookies, no SDK, no config file. On WordPress? Install the plugin.
A bell icon and panel that drop into your own nav bar — styled to match, isolated so it can't clash with your CSS.
Every project gets a hosted page and a real RSS feed, for the users who never open your app but still want to know what changed.
Three entry types, colour-coded, written in a lightweight Markdown so you can bold, link, and list.
Visitors see a count on the bell until they open it. Tracked locally in their browser — nothing to configure.
A one-tap 👍 on every entry, in the widget and on the public page — the lightest possible signal that people noticed.
Drop in a webhook URL and your team gets pinged the moment something ships. No Zapier needed.
Visitors can subscribe on your public page and get a plain email when you publish — with one-click unsubscribe.
Turn on a "Send feedback" tab in the widget. Users tell you what they want next, and it lands in your dashboard and your inbox. More on the feedback widget →
Tag a commit with [log], publish a release or close a Linear issue, and a draft waits for you. Nothing goes live until you review it.
One click turns "fix: null check in invoice export" into a sentence your customers understand. Included in Pro. See more examples in our guide to writing good release notes →
See how many people opened each update and clicked its links. Daily counts only, no cookies, no IP addresses stored.
Upgrade the day it actually matters — not before.

Real products that tell their users what shipped with Fizlog.
No. The whole widget is under 7 kB compressed, loads asynchronously, sets no cookies, and renders inside an isolated shadow DOM, so it can't block your page or fight your CSS.
Yes. On the Pro plan you can hide it per project with one switch in the dashboard.
No. The widget only reads public changelog entries you write. Read receipts are tracked in each visitor's own browser, not on our servers. The only visitor data we store is what someone chooses to send through the optional feedback form.
Yes — billing is self-serve through Stripe's own portal, one click from your settings page.
A few minutes. Paste one script tag, write your first entry, and the widget, public changelog page and RSS feed are all live — no backend integration or config file needed.
Those tools bundle a changelog with feedback boards, roadmaps or per-MAU pricing. Fizlog is deliberately just the changelog (plus an optional feedback tab), free for one project — see the full breakdown on the compare pages.
Yes — every project can export its entries as JSON or Markdown at any time from the dashboard. There's no lock-in.
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.
