Nitrozen

Nitrozen is a product changelog platform that makes it effortless to publish product updates, embed a changelog widget in your app, and host public changelog pages — with Markdown support and custom domains.

Every project gets a clean, public changelog page you can share with anyone. Drop a single script tag into your app and an asynchronous widget shows users a badge for new entries and a panel with your latest updates, without ever leaving your product. On paid plans, point your own domain at the changelog with DNS verification.

Entries are organized as New, Improvement, Fix or Announcement, with color-coded badges so users can scan what changed at a glance. Write in Markdown with code blocks and lists, and manage changelogs for multiple products from one dashboard.

Nitrozen is built for developers. A REST API (16 endpoints) covers projects, entries, tokens and public data. Official SDKs exist for Node.js (TypeScript, npm install nitrozenio), Go (go get github.com/nitrozenio/nitrozen-go) and Python (Pydantic v2, pip install nitrozenio). A Terraform provider (nitrozenio/nitrozen) lets you manage changelogs as infrastructure code, and a GitHub Action (nitrozenio/changelog-action@v1) publishes an entry straight from a GitHub Release. An MCP server connects Claude, Cursor and other AI assistants so you can create and publish entries in natural language.

Pricing: Free plan (1 project, 5 entries/month, public page, Markdown, badges and widget, no credit card). Pro $9.99/mo, Business $29.99/mo, and a $49 Lifetime Deal. Cancel anytime; you drop to free and your entries are never deleted.
