The shortlist

Automate browser tasks

Form-filling, scraping behind logins, multi-step web workflows — browser agents drive a real browser the way a person would. The field splits into open-source projects you run yourself and managed platforms that host the browser for you.

3 picks · chosen editorially from the index · how we choose

Best overall

Self-host — pip install

browser-useAgent

104k stars · Open source · Python

The most widely adopted open-source browser agent in the index by a wide margin, with an active release cadence. Python-first, works with the model provider you choose.

Watch outYou want a hosted, no-code browser automation product.

Vision-based alternative

Self-host — Docker

skyvernAgent

22k stars · Open source · Python

Uses vision + DOM together, which holds up better when page layouts shift. Fully self-hostable if you want the automation on your own infrastructure.

Watch outYour target sites break vision-based automation and need API integrations instead.

Before you commit

Browser agents are the least deterministic agent class: selectors change, sites add bot-detection, and a mis-click can submit something you didn't intend. Keep a human review step on anything irreversible (purchases, form submissions, account changes), and test on the real target sites before trusting a schedule.
