Introduction

SeleniumLibrary is a web testing library for Robot Framework that uses Selenium internally. It is one of the oldest and most widely used Robot Framework libraries and lets testers write browser tests as keywords such as Open Browser, Input Text, Click Button and Page Should Contain.

The current release line works with Selenium 4 and supports Python 3.10 through 3.13, according to the README. Installing it with pip install --upgrade robotframework-seleniumlibrary also installs the latest Selenium and Robot Framework. The project history goes back to the original SeleniumLibrary, which was forked as Selenium2Library and later renamed back.

Because it is built on Selenium WebDriver, it can run against local browsers, Selenium Grid and cloud grids, and teams can extend it with Python keywords or plugins.

In the quality loop it covers end-to-end web testing for Robot Framework users, especially those with existing Selenium infrastructure.

The source code is at robotframework/SeleniumLibrary on GitHub under the Apache-2.0 licence, with about 1,500 stars; the most recent commit was on 10 November 2026.

Features

1. Keyword library: Hundreds of documented keywords for browsers, elements, forms, windows, frames and alerts.
2. Selenium 4: Works with current Selenium and its WebDriver-based browsers.
3. Grid support: Run against Selenium Grid or cloud providers with remote URLs.
4. Plugins and extensions: Extend with plugins or custom Python keywords.
5. Screenshots: Automatic screenshot on failure via Run On Failure.

Pros

1. Mature and stable: Large community knowledge base and long track record.
2. Free to use: Open source under the Apache-2.0 licence, so the core tool costs nothing to use.
3. Actively maintained: The repository had commits as recent as 10 November 2026.

Cons

1. WebDriver timing: Needs more explicit waits than Playwright-based Browser library.
2. Slower releases: Releases are less frequent than in newer libraries (latest at time of writing: v6.9.0, May 2026).
