Show HN: Claude Code plugin that adds CRDT collaboration to any app in 10 min [video]

We built a Claude Code plugin for Velt that installs real-time collaboration into any app in under 10 minutes. What gets installed in one command: - CRDT (live document sync) - Contextual comments & threaded replies - Live presence & cursors - In-app notifications - Reactions The problem we kept seeing: engineering teams know they need collaboration features. They also know how long it takes to build right. CRDT alone is a multi-week project. So it either gets deprioritized forever or ships half-baked. We've been building this infrastructure for 3 years. Pendo, HeyGen, and LambdaTest use it in production. The Claude Code plugin is our attempt to make the installation feel as simple as the API already is.
