Uindow vs. Selenium
Stop forcing your teams to use Stale Selenium
Your team deserves a faster, smarter way to test. Leave behind clunky scripts and discover a tool built for today's workflows.

Build. Test. Launch. Better.
Powerful functional testing made simple. Automate, validate, and ship with confidence.

Selenium
Support for all browsers
- Uindow cannot control other browsers on your computer.
- Selenium uses the W3C WebDriver protocol to partially control most web browsers.
Support for Chromium
- Uindow is built on top of the Chromium browser. It has full control over browser sessions using the Chrome DevTools Protocol (CDP).
- The Selenium IDE add-on is no longer compatible with Google Chrome. The W3C WebDriver protocol can only issue untrusted/synthetic events.
Trusted events
Uindow controls the underlying Chromium browser directly and sends trusted events for all user interactions. Websites see all events as native events issued by a real user with a real input device.
Real mouse events
Websites perceive all your automated actions as being triggered by a real mouse moving naturally in a non-linear manner between actions.
Native file uploads
Uindow uses the Chrome DevTools Protocol to perform safe and trusted file uploads, as if they were initiated by a real user.
Native selections
Uindow uses a combination of keystroke and CDP events to accurately change the values of
<select /> and <select multiple /> HTML elements.Safe user inputs
Never hard-code user data again! Instead, provide sensitive inputs safely for each automation run directly through the user interface.
Comprehensive results
Uindow allows you to gather far more than a simple "pass/fail" for each run:
- Primitive types: integers, strings, booleans
- Objects as table rows
- Binary data and request results
- Downloaded files
- Screenshots
- Video recordings
Scheduled and recurring runs
Large Language Model
Some tasks, like summarization or sentiment analysis, are not suited for regular programs. Interact with a small LLM running directly on your computer for maximum privacy.
Shareable modules
Export automations as YAML-based modules for easy review and sharing.
Powerful IDE
- Uindow gives you full control over your automations with pure JavaScript and a real IDE with auto-formatting, and linting.
- Selenium still depends on browser extensions that struggle to keep up. And when they do open, you're left working in what feels more like a spreadsheet than an IDE.
Finite-state machine
- Uindow understands that browser interactions are complex, and that the best way to model them is by using a finite-state machine.
- Selenium provides a
for eachcommand.
Custom functions
Avoid code duplication by organizing your logic into separate functions outside the main finite-state machine states.
Request proxy
You can safely and easily make requests that would otherwise be blocked by CORS.
Environment variables
Store values between consecutive automation runs.
Global variables
Temporal control
Skip between finite-state machine states, pause automations at any time to request user input, and schedule future events.
Detailed logs
Store detailed logs of your automations, and filter them in real time by content or type.
