Flue 1.0 Beta, announced June 16, 2026 by Fred K.

Brief

Flue 1.0 Beta, announced June 16, 2026 by Fred K. Schott, is a TypeScript framework for building agents with an open harness and zero LLM lock-in. The release centers on three primitives—Workflows, new autonomous stateful Agents, and Channels for Slack/GitHub/Linear/Discord/Teams—backed by Pi, Vite, and Durable Streams for durable, deploy-anywhere agents that survive restarts and downtime.

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!
