Nitrozen

Nitrozen is a changelog platform for SaaS teams that want to tell customers what shipped without writing a separate email every time. You write updates in Markdown, tag each one as New, Improvement, Fix or Announcement, and publish to a clean public changelog page. On paid plans the page can live on your own domain, so release notes stay on your brand. An async script tag adds an in-app widget with a "new" badge, so users see what changed without leaving your product. The widget loads fast and does not need a framework, which makes it easy to drop into any web app. Developers get a REST API, SDKs for Node.js, Go and Python, a Terraform provider and a GitHub Action that posts entries straight from your releases. An MCP server lets Claude or Cursor draft and publish updates, so release notes can be part of your normal coding workflow instead of a chore left until later. Who is it for? Small SaaS teams, indie founders and product managers who want release notes that customers actually read, with minimal setup. Pricing is freemium: the free plan includes one project and five entries a month, Pro is $9.99 a month and Business is $29.99 a month. Nitrozen first went live in February 2026 and is built with Laravel, PHP, Tailwind CSS and Alpine.js. It is a lighter alternative to Beamer, Headway, LaunchNotes, AnnounceKit and Noticeable.
