Thread Safe Python Packages

moka-py

A high performance caching library for Python written in Rust

atomic-lru

Thread-safe, dependency-free in-memory LRU storage library for Python 3.10+ (with optional TTL)

melder

High-performance Dependency Graph Runtime for Python 3.14+, combining thread-safe DI, scoped lifecycles, dynamic composition, and runtime introspection for free-threaded applications.

logifyx

logifyx is a production-ready Python logging library with structured logging, colored output, file rotation, Kafka/HTTP support, and sensitive data masking.

b-rabbit

A thread safe library that aims to provide a simple API for interfacing with RabbitMQ. Built on top of rabbitpy, the library make it very easy to use the RabbitMQ message broker with just few lines of code. It implements all messaging pattern used by message brokers

apywire

Lazy object wiring and dependency injection for Python 3.12+

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.

s3m

sqlite3 wrapper for multithreaded python applications

pynnex

PynneX provides a modern emitter-listener (signal-slot) pattern with thread safety, async support, and dynamic connection detection. Build decoupled architectures without heavy frameworks. It’s pure Python 3.10+; minimal overhead. Choose from multiple aliases (signal-slot or publisher-subscriber).

d-memfs

In-process virtual filesystem with hard quota for Python

pretty-pie-log

Pretty Pie Log: A powerful, thread-safe Python logging library featuring colorized output, structured logging, timezone-aware timestamps, rotating file logs, and function execution tracking with enhanced support for any data type in details.

safethread

Python classes for safe deployment and management of Threads, Processes, synchronization primitives (Locks, Barriers, etc), thread-safe, and process-safe Python data structures (lists, dicts, sets, etc).

openai-cost-logger

Thread-Safe OpenAI Cost Logger

save-thread-result

Simple subclass wrapper around `threading.Thread` to get the return value from a thread in python. Exact same interface as `threading.Thread`! 🌟 Star this repo if you found it useful! 🌟
