Spreadneedle is for vibe coding in AI chats. When an AI generates HTML versions faster than you can keep track of them, Spreadneedle turns those builds into a visible version trail.
Spreadneedle is a lightweight version trail for vibe-coded HTML projects. It is built for people who create with AI chat, test many small builds, and need a clear way to see what changed, what worked, and where the project went.
