GraphBit
Rust-core, Python-first Agentic AI framework
Visit website →About
GraphBit is a framework for building AI agents with a core written in Rust and a Python-first API. The Rust core handles the performance-sensitive work, such as concurrency, scheduling, and execution, while developers write agent logic in Python through clean bindings.
The result aims to combine Rust's speed and reliability with Python's ease of use, so teams can build agents that stand up to enterprise workloads without dropping to a lower-level language themselves.
It is aimed at developers and platform teams building production agent systems who care about throughput, stability, and resource use, and who want a framework that does not force a trade-off between performance and developer experience.

Why we picked it
GraphBit earns its spot for the split itself — Rust handling concurrency and scheduling while you write agent logic in Python — worth naming for a team that's hit the performance ceiling of a pure-Python agent framework but doesn't want to give up Python's ease of use entirely.
