Introduction

Helium is a Python library for automating browsers such as Chrome and Firefox. Under the hood it forwards each call to Selenium, but its API is much higher level. In Selenium you identify elements with HTML IDs, XPaths and CSS selectors; in Helium you refer to them by the labels a user sees, such as click('Sign in') or write('alice', into='Username').

The README says Helium scripts are typically 30 to 50 per cent shorter than equivalent Selenium scripts and easier to read. Helium also handles iframes and new windows automatically and waits for elements implicitly, removing a lot of boilerplate.

Because it sits on Selenium, you can mix Helium and Selenium calls in the same script and get the underlying driver with get_driver() when you need something Helium does not wrap. That makes it a gentle way to make existing Selenium-based Python tests more readable.

In the quality loop, Helium is a lightweight choice for end-to-end checks and quick automation scripts in Python, often run with pytest.

The source code is at mherrmann/helium on GitHub under the MIT licence, with about 8,300 stars; the most recent commit was on 22 October 2026.

Features

1. Label-based selectors: Click, type and assert using visible text and labels.
2. Implicit waiting: Waits for elements before acting.
3. Iframe and window handling: Switches frames and windows automatically.
4. Selenium interop: Get the Selenium driver at any time for low-level control.
5. Chrome and Firefox: Starts browsers with start_chrome() or start_firefox(), including headless.

Pros

1. Very readable scripts: Non-specialists can read and edit tests.
2. Small API: Quick to learn from the cheatsheet.
3. Free to use: Open source under the MIT licence, so the core tool costs nothing to use.
4. Actively maintained: The repository had commits as recent as 22 October 2026.
5. Community: About 8,300 GitHub stars.

Cons

1. Label ambiguity: Pages with repeated labels may still need explicit selectors.
2. Small maintainer team: Mostly maintained by its author.
3. No built-in test runner: Pair it with pytest or unittest.

assert Text("Welcome").exists()
kill_browser()
