Nitrozen

Nitrozen is a changelog platform for SaaS teams. Write updates in Markdown, tag them New, Improvement, Fix or Announcement, and publish to a clean public changelog page, on your own domain on paid plans. One async script tag adds an in-app widget with a "new" badge so users see what shipped without leaving your product. Developers get a REST API, SDKs for Node.js, Go and Python, a Terraform provider, a GitHub Action that posts entries from releases, and an MCP server so Claude or Cursor can draft and publish updates. Free plan: 1 project, 5 entries a month. Pro $9.99/mo, Business $29.99/mo.
