Robyn: A fast async Python web framework with a Rust runtime

Sanskar Jethi

Python web frameworks such as FastAPI, Flask, Quartz, Tornado, and Twisted are important for developing high-performance web applications and for their contributions to the web ecosystem. However, they may also present certain bottlenecks, either due to their synchronous nature or due to the usage of the Python runtime. These limitations can often arise from their reliance on *SGIs, which can limit the speed and performance of the web application. This is where Robyn comes in. Robyn aims to achieve near-native Rust throughput while still allowing developers to write code in Python. This means that developers can enjoy the benefits of high-performance web applications while still using the language they are comfortable with. In this talk, we will delve into Robyn and explore how it can improve web application performance. We will also discuss the development of Robyn and examine the evolution of a project from ideation to community support. We will examine the challenges and opportunities that arose during the development and how they were addressed.
