Just Shipped: Flue 1.0 Beta
Flue is the TypeScript framework for building the next generation of agents, designed around an open agent harness with zero LLM lock-in. It’s like Astro, for agents.
Flue 1.0 has been redesigned around three core primitives:
🔁 Workflows — structured automations designed for background work, where your code drives the agent from start to finish.
🧭 Agents (New!) — autonomous, stateful loops where the model drives itself to complete a given task.
📡 Channels (New!) — connect agents to Slack, GitHub, Linear, Discord, Teams, and more. Flue handles the boilerplate for you.
Everything shares the same durable foundation, powered internally by Pi, Vite, and Durable Streams. Deploy anywhere, use any LLM, and recover running agents across restarts and downtime.
We’ve talked to a lot of teams building agents, and keep hearing the same thing: getting to production is hard work. We built Flue to help change that.
Flue 1.0 Beta is available today. Give it a try and let me know what you think!

We started with *just shipping skills via node_modules* in our libraries, which BTW is versioned skills whether you like it or not and that's a good thing; security requires provenance and NPM isn't perfect, but it's better than inventing something new (insert standards meme). But as you also learned early on, you have to have a (hopefully) small step where you teach your agent about those skills, or at the very least where to fine them. That is precisely what TanStack Intent is. It's a spec (and a CLI) for skill discovery over NPM. A single install command to cover the many agent harness quirks and teach them about available NPM skills for any library that follows that spec. The spec is only half of it too. Simply saying there are skills in NPM isn't enough, and installing every skill you can find into your agent's context is costly. So Intent is also a CLI that allows your agent to cache, search and recall skills found in your node_modules (again, accounting for all of the quirks across the many package manager implementations).

Flue from @Cloudflare is now based on our @DurableStreams protocol!

We use Flue in Astro to run issue triage in GH CI. It reproduces the bug report, diagnoses the cause, verifies that it is a bug (and not intentional behavior) applies a fix, writes a test, and then creates a preview release for users to try. Here's an end-to-end fix in about an hour:

Very excited about Flue and the new native integration with Braintrust. Agent tracing is quite a bit different than traditional LLM apps and evolving quickly.

This is huge! One of the most elegantly designed agent framework I have read.
LLM provider AND hosting platform neutral as well!
Absolutely no lock-in.

wild that this was just last month:

Introducing Flue — The First Agent Harness Framework
Flue is a TypeScript framework for building the next generation of agents, designed around a built-in agent harness.
Flue is like Claude Code, but 100% headless and programmable. There's no baked in assumption like requiring a human operator to function. No TUI. No GUI. Just TypeScript.
But using Flue feels like using Claude Code. The agents you build act autonomously to solve problems and complete tasks. They require very little code to run. Most of the "logic" lives in Markdown: skills and context and AGENTS.md.
Flue is like Astro or Next.js for agents (not surprising, given my background 🙃). It's not another AI SDK. It's a proper runtime-agnostic framework. Write once, build, and deploy your agents anywhere (Node.js, Cloudflare, GitHub Actions, GitLab CI/CD, etc).
We originally built Flue to power AI workflows inside of the Astro GitHub repo. But then @_bgiori got his hands on it, and we realized that every agent needs a framework like Flue, not just us.
Check it out! It's early, but I'm curious to hear what people think. Are agents ready for their library -> framework moment?

pastries with @rickyrobinett in the morning, now nerd-sniped into (finally) building a personal agent.
using Flue "agents" to break up tasks (general research vs. grocery automation vs. others), Browser Run for web search/playwright automation. Email driven (for now).

built a chat research agent on Flue this afternoon.
it’s called Ferdinand, for old Porsche diagnostics & research.
Flue for the harness, Chat SDK for chat (duh!), Cloudflare AI Gateway Workers for the app, and Durable Objects for session history & user state.

The Astro team just open-sourced Flue, a framework turning Claude Code into a headless agent system. Virtual sandboxes replace real containers, making it drastically cheaper to scale AI agent fleets. Watch our video to see how it works.
