Open Source Browser Extensions Software
Browser Extensions software adds specific functions to web browsers to automate repetitive tasks, block advertisements, and analyze text. These tools modify how pages load or provide new interfaces for scraping data and recording screen activity. Developers and privacy-conscious users benefit from these apps because they can host the backend logic on their own hardware. This approach ensures that grammar checks, network filtering rules, and scraped web content remain on a private server instead of passing through external company infrastructure.
This page lists 9 open source tools in the Browser Extensions category. The most popular are Automa, Screenity and LanguageTool. Most use the MIT or Apache-2.0 license, and 6 offer an official Docker image.
