Dear friends,
When I first announced Flyte 2 last year, I promised we were building something big. Today, I get to say: we did it.
Flyte 2 is here — locally, in open source, for everyone.

💻 you can also find a
live in-browser demo on this page, no install required.
What is Flyte 2?
This is fully dynamic, self-healing AI orchestration. Pure Python authoring. A terminal UI you'll actually love. Durable agent workflows that recover from failures on their own — including infrastructure failures like OOM errors and container pre-emption that most "durable execution" tools simply can't handle.
What you can run today, locally:
Durable agent workflows - orchestration AI and agents locally
Terminal UI - launch, inspect, and manage workflows straight from your laptop
Async I/O - non-blocking, concurrent task execution out of the box
Local caching - reuse prior results to speed up iteration and reruns
Local serving - serve apps that call workflows and execute agentic logic locally
🙏 Thank you. Genuinely. Every PR, every Slack message, every piece of feedback helped shape what Flyte 2 is today.
A full Production K8s scale deployment is next. Flyte 2 (Union backend) is already available deployed in your cloud as part of our production preview on
Union.ai
Let us know here if your team wants in.
In the meantime: try it, push it to its limits (if you dare), tell us what you think.
With gratitude and momentum,
Ketan
Co-creator of Flyte
P.S. If you've been waiting to share Flyte with your team or on socials, now's the moment. It means more than you know.
