Patchlog is a drop-in changelog for web apps. You embed one script tag, with no SDK and no npm install, and get an in-app "what's new" widget plus a hosted changelog page and an RSS feed.

The widget renders inside a Shadow DOM, so it never inherits or leaks the host page's CSS, and it behaves the same in React, Vue, Rails or plain HTML.

Other features: scheduled publishing so you can write updates ahead of time and have them post themselves, per-update view and click analytics, light/dark/auto theming with a custom accent colour on Pro, and 2FA on accounts.

Pricing is flat rather than metered on your traffic: free for 1 project and 25 updates, which shows a small "Powered by Patchlog" badge, or $7/month ($60/year) for unlimited projects and updates, badge removal and advanced analytics. Most tools in this category bill per monthly active user, so the bill grows with your app even though writing release notes does not get harder.

What Patchlog does not do: no user segmentation or targeting, no NPS surveys, no roadmaps or feature voting boards, no email digests, and no public API. If you need those, Beamer or Canny is the better fit.

Overall verdict

  • I don't have verified, up-to-date information about Patchlog (patchlog.io) to make a reliable assessment of its quality.

Questions & Answers

As answered by people managing LangSmith and Patchlog.

What makes your product unique?

Patchlog's answer:

A real free plan with no trial expiry, and a widget that embeds in any web app with two lines of JavaScript. No bloated feature set, no enterprise pricing for a tool that should be simple.

Why should a person choose your product over its competitors?

Patchlog's answer:

Most changelog tools charge $29-$60/month for features most small teams never use. Patchlog gives you a working in-app widget, a public SEO-friendly changelog page, full Markdown support, and RSS on the free plan. The Pro plan is $5/month. It covers everything 90% of SaaS products actually need.

How would you describe the primary audience of your product?

Patchlog's answer:

Indie founders, solo developers, and small SaaS teams who want to keep users informed about product updates without paying enterprise prices for it.

What's the story behind your product?

Patchlog's answer:

Built out of frustration with the existing options. Every changelog tool was either too expensive, too complex, or offered a "free trial" that expired before you could evaluate it properly. Patchlog started as the tool we wished existed: simple to embed, honest free tier, no fluff.

Which are the primary technologies used for building your product?

Patchlog's answer:

Laravel, Vue 3, Inertia.js, Tailwind CSS, MySQL.

Who are some of the biggest customers of your product?

Patchlog's answer:

Patchlog is early-stage and does not publicly disclose customer names at this time.

  • How to embed a widget on any site without CSS collisions (Shadow DOM)
    This is exactly how I built the changelog widget for Patchlog. It is a drop-in "what's new" widget for SaaS products: one script tag, rendered inside a Shadow DOM so it never collides with the host site's CSS, with light, dark, and auto theming that reads the host's CSS variables when you want it to. There is a free tier if you want to see the technique in a shipped product rather than a blog snippet. - Source: dev.to / 22 days ago
  • How to add a changelog to any web app with one script tag
    I build Patchlog, so the snippet above is my own tool. I'm not going to pretend otherwise. It's early: the free tier is one project and 25 updates, which is genuinely what I run on my own projects. I'm sharing the approach because it's helped me, and if it saves you the afternoon it cost me to think through, great. - Source: dev.to / 23 days ago
