Your ideas start as code now,
not designs.
Teams used to design and then build. Now they go straight to code with Cursor, Claude Code, or Loveable. That's faster... but we lost the ability to click anywhere and leave a comment. The ability to collaborate easily.
Holler brings it back. Your team comments in the browser. Your AI agent can read and acts on feedback from the terminal. Same thread, same prototype.
Three steps to comments.
Supabase project
Create a free project at supabase.com. Run npx @holler-vibe/cli to set up the database. Done in 2 minutes.
One script tag
Add <script src="holler.umd.js"> to your page. A comment overlay appears. Click anywhere to leave feedback.
Agent CLI
Your AI agent reads, posts, and resolves comments via the holler CLI. No browser needed.
Your agent's interface.
Cursor, Claude Code, or any coding agent can list, post, and resolve comments without opening a browser. Each comment includes the CSS selector and text of what was clicked, so your agent knows exactly what to fix.
