Introducing Watch Changelog

Stop writing custom scrapers for vendor changelogs. Watch Changelog aggregates hundreds of vendor changelogs—AWS, Vercel, GitHub, React, and more—into one consistent JSON format.

The Problem

GTM and sales teams need to track product changes across dozens of vendors. Competitive intelligence systems, sales enablement tools, and marketing automation all require fresh changelog data. Today, that means:

• Writing custom scrapers for each vendor
• Maintaining brittle HTML parsers
• Handling rate limits and blocking
• Normalizing different date formats, link structures, and schemas

The Solution

Watch Changelog provides a uniform API and MCP server that:

• Fetches from RSS feeds, Atom feeds, GitHub releases, and HTML changelog pages
• Normalizes every entry to the same schema (title, URL, published date, summary, tags)
• Refreshes politely with etag/last-modified caching and exponential backoff
• Tracks health and investigates failing sources automatically

How It Works

1. Browse the catalog of 65+ sources (AWS, Azure, GCP, Vercel, agent frameworks, databases, observability tools)
2. Query via REST API with plan-gated access (Free: 3 sources, Starter: 10, All: unlimited)
3. Or connect via MCP server for AI agent workflows

Every source includes lastUpdatedAt (the vendor's own timestamp) so you can sort by "recently updated" and focus on vendors actively shipping.

What's Next

We're adding:

• More agent-system vendors (agent inboxes, MCP tools, agent frameworks)
• Diff API ($49.99 add-on) for before/after comparisons
• Webhooks for real-time notifications
