splinter vs MechanicalSoup
Python web automation libraries compared
splinter and MechanicalSoup both help Python programs interact with websites. splinter automates a browser through drivers such as Selenium, while MechanicalSoup uses HTTP sessions and HTML parsing without executing JavaScript.
splinter: Automate Web Browser Interactions in Python
Splinter provides a Python API for automating browser interactions in web application tests. Use it to exercise pages through drivers such as Selenium, or when you want a higher-level interface that can still access Selenium directly.
MechanicalSoup: Automate Website Interaction with Python
MechanicalSoup lets Python programs interact with websites through HTTP sessions and parsed HTML, including following links and submitting forms. It suits scripted web tasks that do not require JavaScript execution.
