As a visual person, I hate working in the CLI. But after using Claude Code a few times, it’s impossible to go back. The problem isn’t Claude. It’s the interface around it. So we built the best Claude Code client we could imagine. Runs fully in the browser. Parallel branches and projects. Live previews for every change. A calm, clean UI. Free to use with your own Claude keys. Reply if you want early access 👀

Introducing Agents by 21st (alpha) We love Claude Code. We hate living in the CLI. So we built a calm, visual client for real code work: • works with your own Claude subscription • local work with worktrees + multiple sessions • multiple terminals per worktree • diff viewer, commits, PR control Built for people who think visually.

We're launching 21st Agents in beta. It's the infrastructure layer for Claude Agent SDK - runtime, sandboxing, billing, UI, streaming - so you can ship agents to production without building infra from scratch. Think Vercel for Claude Agent SDK. Full walkthrough in the video below 👇

21st lets you work on real frontend code in the browser you can iterate on multiple branches and projects in parallel, with live previews it’s my favorite tool for frontend (and yeah, i’m building it using itself) p.s. comment if you want free tokens 👀
