How the trade-offs apply to your team
Guidance below is inferred only from catalog differences. It is not a winner pick.
Consider Selenium if…
- you need coverage for Chrome, Edge, Firefox, Internet Explorer
- your team writes tests in C#, JavaScript, Kotlin, PHP
- you want an MCP server for AI assistants
- you care about Action chains and Browser automation
Consider Robot Framework if…
- you need coverage for Android, iOS, Linux, macOS
- your team writes tests in .NET
- you want a lower-complexity tool
- you care about Behavior-driven development and Built-in reporting
Questions to verify before choosing
- Confirm current pricing and packaging on the Selenium and Robot Framework websites.
- Trial both tools against a real slice of your application, not a demo site.
- Verify the exact browser, device, or OS matrix you must support.
