# 🦉 Extra Stuff 🦉 To help work/improve/learn with OWL, we have here: - a benchmarks application - a playground application Both of them can be accessed by using a static http server. A simple python server is available in `server.py`. There is also a npm script to start it: `npm run extras` (and its version with a watcher: `npm run extras:watch`). ## Benchmarks The benchmarks application is a very small application, implemented in different frameworks, and in different versions of Owl. This is a simple internal tool, useful to compare various performance metrics on some tasks. ## Playground The playground is an important application designed to help learning and experimenting with Owl. It is available [online](https://odoo.github.io/owl/playground/).
