What is Selenium?
Browser automation tool for automating web applications for testing purposes, including regression testing, bug reproduction, and exploratory testing. Also supports automation of web-based administration tasks.
Selenium pricing
We don't have Selenium's full plan breakdown yet (its pricing page resisted automated reading). Here's what we could confirm. Always check live pricing for exact numbers.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Selenium, not the verdict.
