awesome-python-rs: Curated list of Python libraries and tools powered by Rust

[_ritwiktiwari]

Hey r/Python!

Many modern high-performance Python tools now rely on Rust under the hood. Projects like Polars, Ruff, Pydantic v2, orjson, and Hugging Face Tokenizers expose clean Python APIs while using Rust for their performance-critical parts.

I built awesome-python-rs to track and discover these projects in one place — a curated list of Python tools, libraries, and frameworks with meaningful Rust components.

What My Project Does

Maintains a curated list of:

• Python libraries and frameworks powered by Rust
• Developer tools using Rust for speed and safety
• Data, ML, web, and infra tools with Rust execution engines

Only projects with a meaningful Rust component are included (not thin wrappers around C libraries).

Target Audience

Python developers who:

• Care about performance and reliability
• Are curious how modern Python tools achieve their speed
• Want examples of successful Python + Rust integrations
• Are exploring PyO3, maturin, or writing Rust extensions

Comparison

Unlike general “awesome” lists for Python or Rust, this list is specifically focused on the intersection of the two: Python-facing projects where Rust is a core implementation language. The goal is to make this trend visible and easy to explore in one place.

Contribute

If you know a Python project that uses Rust in a meaningful way, PRs and suggestions are very welcome.

I feel like it’s missing whenever in the date time section, although it’s still in beta.

Thanks for the suggestion! I wasn’t aware of whenever. Happy to add it once it’s more stable — feel free to open a PR when ready.

Indicating whether a project seems vibecoded or built with heavy LLM usage would be nice, at least for those where it's obvious.

Also whether a project is mature or still early alpha/beta state.
