21 Best Online Cross-Browser Testing Tools In 2023

Testim is a low-code tool with a modern, intuitive UI. Tests are created with a Chrome extension that records a user’s actions. Tests can be edited in the Testim visual editor to rearrange steps, create reusable groups that are shared across tests, add assertions or code-like functions, including loops, and conditions.

Cross-browser tests can be initiated by the built-in scheduler or from a CI action. Testim integrates with all significant CIs. Testim’s test status feature enables users to treat test failures differently as they run in the CI (stop the build, pass the build with info only). Testim integrates with popular version control systems for code/test branch synchronization and collaboration and bug tracking tools.

View test results from the dashboard that shows the last ten runs for each test. Failures can be quickly diagnosed with failed step indicators and before/after screenshots, parsed consoles, and network logs. Testim even aggregates failure types to help triage test run results.

Testim’s biggest value driver stems from the AI-powered locators that keep tests stable, reducing maintenance costs, and customer case studies indicate fast authoring and root cause features also generate time savings.

Testim is free for up to 1000 runs/month. Higher-level plans offer customized pricing upon request.
