I had 14 tabs open just to keep up with AI.
arXiv, Papers With Code, every leaderboard, HuggingFace, half a dozen RL-env hubs...
So I built one screen for all of it.
The Bloomberg terminal for AI research.
It's called Sophon 🧵
Introducing @21st_dev Agent Elements
Diffed edits. Plan approvals. Clarifying questions. Sub-agents. Tool cards. The pieces every "agent UI" lib skips.
25 @shadcn /ui components built for the new generation of agents that use your computer.
Open-source. Link in thread 🧵
built a thread generator agent on @21st_dev SDK.
→ drafts X threads end-to-end
→ ray.so-style code blocks, 18 themes
→ matches your voice from a X handle
→ OG link previews + inline video cards
100% open-source. you can run it in 60 seconds 🧵
built a SQL agent UI with @21st_dev SDK
— chat to query OR mutate a live table grid
— read/write toggle sits right in the chat input
— new rows pulse green when the agent INSERTs
— the active tab follows whatever the agent touches

Generate websites with OpenClaw 🦞
Add the @21st_dev MCP in @atomicbot_ai
Your agent runs the flow:
→ Generates UI variants
→ Picks the best result
→ Ships it into your desktop project
Open-source. Local models supported.
Introducing Agent Registry for Anthropic Managed Agents on @21st_dev
Find the right config in seconds:
→ Semantic search - describe what you need, not keywords
→ Browse by MCP server - Slack, GitHub, Postgres, Sentry…
→ Filter by category - coding, devops, research, data,
Your docs agent should not stop at “not found in docs.”
So I turned our docs template into a simple support agent.
If the docs cannot answer, the agent forwards the question to your team by email.
Built with Claude Code + 21st SDK + @resend
Takes just a few minutes to add.
Stop sending users to a docs tab.
Let them chat with docs inside your product.
- Built with Claude Code + @21st_dev SDK
- Works especially well with @mintlify
- Setup takes ~2 minutes.

We had no idea when engineers from OpenAI or Stripe signed up.
So we built a lead research agent.
Claude Code + @ExaAILabs researches each signup by email and pings Slack when someone interesting appears.
Template on 21st 👇
Big update: 21st SDK x @OpenRouter 🤝
Now you can keep runtime: "claude-code" and run your agents on OpenAI / Gemeni models via OpenRouter model IDs.
Same Claude Code-style workflow. More model choice.
