A powerful embedded web server for MicroPython and CPython with WebSockets, routes, and optimized async I/O for IoT and large servers.
MicroWebSrv2 is an embedded web server for MicroPython and CPython that provides asynchronous HTTP/WebSocket serving with route handling, template rendering, and SSL/TLS support. It solves the need for a lightweight yet powerful web server on resource-constrained IoT devices (like ESP32, STM32) and scalable server environments, enabling developers to build web interfaces, APIs, and real-time applications directly on embedded hardware or Python servers.
IoT developers using MicroPython on devices like ESP32, Pycom WiPy, or STM32 Pyboards, as well as Python developers needing a lightweight async web server for embedded or edge computing projects.
Developers choose MicroWebSrv2 for its highly optimized async architecture, which supports thousands of concurrent connections with minimal memory overhead, and its rich feature set—including WebSockets, route handlers, and a template engine—that is rare in embedded web servers.
The last Micro Web Server for IoTs (MicroPython) or large servers (CPython), that supports WebSockets, routes, template engine and with really optimized architecture (mem allocations, async I/Os). Ready for ESP32, STM32 on Pyboard, Pycom's chipsets (WiPy, LoPy, ...). Robust, efficient and documented!

Uses fully asynchronous I/O with optimized memory management, supporting thousands of concurrent connections on resource-constrained devices, as highlighted in the README's focus on scalability for IoT and server deployments.
Offers predefined configurations (embedded, light, normal, large) with fine-tuned memory buffers and connection queues, ensuring efficient resource usage for microcontrollers like ESP32 and STM32.
Includes a WebSockets module for real-time bidirectional communication with sub-protocol negotiation, enabling chat applications and live data streaming directly from the demo examples.
Supports URL routing with variable arguments for HTTP methods (GET, POST, etc.), making it easy to build RESTful APIs and dynamic handlers, as detailed in the Web Routes section.
Comes with PyhtmlTemplate for HTML rendering using embedded Python, allowing dynamic page generation without external dependencies, demonstrated in the test.pyhtml demo.
Focused on MicroPython and CPython for embedded use, so it lacks the extensive third-party libraries, tutorials, and community support of mainstream frameworks like Flask or Django.
Requires manual tuning of buffer sizes, thread counts, and deployment settings for optimal performance, which can be overwhelming and error-prone, as noted in the Configuring web server section.
Relies on the external XAsyncSockets library for async operations; issues or updates in this dependency could affect stability and require additional management, adding complexity.
Lacks built-in features for common web development tasks like ORM, form validation, or session management, forcing developers to implement these from scratch, increasing development time.
