Bringing Agents to the Web with Angular: Announcing Threadplane

For the past year I've been building AI agents, and shipping them inside Angular apps.

And every single time, the same thing happened: the backend got all the love, and the Angular frontend got the leftovers.

So we built Threadplane.

Threadplane is an open-source framework for building fullstack agentic applications with Angular. It connects your agent runtime — LangChain, LangGraph, anything that speaks AG-UI — to production-ready Angular surfaces: chat, streaming, tool progress, interrupts, durable threads, and generative UI. All of it expressed in Signals, dependency injection, and standalone components. The way Angular actually wants to be written.

Let me tell you why we built it, what's in it, and how to try it this week.
