Vibe Annotations is a free, open-source Chrome extension that transforms the way developers and designers give feedback to AI coding agents like Claude Code, Cursor, GitHub Copilot, and Windsurf. Instead of juggling screenshots, vague instructions, or messy selectors, users can drop visual annotations directly on their localhost websites. Every annotation is captured with full context — DOM structure, styles, and positioning — so AI agents can implement changes accurately in seconds.
Designed for the last-mile problem of vibe coding, Vibe Annotations helps bridge the gap between “almost done” and production-ready. Users can annotate across multiple pages, batch dozens of changes at once, and send them all to their AI coding agent for automated fixes. It eliminates the unproductive cycle of describing UI issues one by one, making it possible to polish and finalize projects faster than ever before.
With local-first architecture, privacy is guaranteed — annotations never leave the developer’s machine. The setup is simple: install the extension, run the companion MCP server, and start annotating. From rapid prototyping to front-end refinement, Vibe Annotations empowers teams to focus on building while AI handles the repetitive fixes. It’s a tool built by developers who were tired of feedback friction, now helping others get from 80% to 100% with minimal effort.
