Hi everyone, I'm Roland, and I'm building PretzelGraph, an open source runtime for AI agents. I just added Vercel AI Gateway as a language model provider.

Most agent/workflow tools hide the agent loop behind code or a node you can't open. In PretzelGraph you design and wire cyclical graphs that act as ReAct agents, so you have full control over the agent's internals. Then you can drop it into other workflows as a single node.

PretzelGraph runs these graphs on its own signal scheduling engine, built for cycles.

You can try it today:

1
git clone https://github.com/RolandTeslaru/Pretzel-Graph
2
cd Pretzel-Graph
3
docker compose up -d  # http://localhost:8080

I'd love feedback, especially on whether building the loop as a graph makes agents easier to understand and change.
