kida-templates

)彡 Kida — Free-threading template engine for Python 3.14+ with AST compilation and modern syntax

ftcheck

Find free-threading bugs in Rust/PyO3 Python extensions: data races, crashes and hangs that only appear without the GIL. Runs your own tests across threads under ThreadSanitizer, plus a static lint and a stress mode.

dexpot

A synchronous Python API framework with adaptive GIL and free-threaded execution.

bengal-pounce

=^..^= Pounce — Free-threading-native ASGI server for Python 3.14+ with real thread parallelism and streaming-first I/O

patitas

ฅᨐฅ Patitas — CommonMark Markdown parser for Python 3.14+ with typed AST and free-threading

bengal

ᓚᘏᗢ Bengal — High-performance static site generator for Python 3.14+ with parallel builds, autodoc, and content validation

rosettes

⌾⌾⌾ Rosettes — ReDoS-safe syntax highlighter for Python 3.14+ with free-threading.

free-threading

Thread-first true parallelism for Python

smalldi

Tiny, zero-dependency DI for Python. Decorators register singletons and interfaces, Provide[T] type hints inject them, overrides swap implementations, and scoped contexts give every test fresh instances. Thread-safe and tested on free-threaded CPython 3.14t/3.15t.

threadfactory

ThreadFactory is a concurrency framework for Python 3.13+ (No-GIL). It provides custom Work future objects and thread-safe collections, laying the foundation for scalable parallel execution in modern Python.

unittest-ft

Run Python tests in parallel with free threading

ftready

Check if your Python project's dependencies are ready for free-threaded Python (3.13t/3.14t)

cythonanyarray

Pass arrays of any dimension to Cython as memory views (no Global Interpreter Lock (GIL))

cynonblockingsubprocess

Nogil subprocess for Python with stdout/stderr capturing and stdin writing - without deadlocking!
