Selenium WebDriver vs Testsigma

Free and open source

Free tier available

Free and open source. The real cost is grid infrastructure or a device-cloud subscription.

Pro and Enterprise cloud plans use custom pricing. Request a quote for your team's platform coverage and execution needs. The community edition is free to self-host, with infrastructure and maintenance managed by your team.

Everything, self-hosted

Apache-2.0 community edition, self-hosted — the GitHub repo is still actively maintained.

• The widest language and browser support of anything in the category, including legacy browser versions.
• A W3C standard, so it will outlive any single vendor. Skills transfer between employers.
• Every device cloud speaks Selenium, which keeps you portable between vendors.

• An open-source community edition adds a self-hosted option alongside the managed cloud.
• Natural-language steps are readable by product owners.
• Web, mobile and API in one authoring model.

• No built-in waiting strategy, reporting, parallelism or assertions — expect to assemble and maintain a framework around it.
• Explicit waits are your problem, and getting them wrong is the number one source of flake in real Selenium suites.
• Out-of-process communication makes it slower than Playwright or Cypress.

• Structured natural-language steps use a defined syntax; plan time to learn it during onboarding.
• The community and cloud editions differ in feature coverage; check the edition against your requirements.

Enterprises with polyglot teams, legacy browser requirements, or an existing grid investment.

QA teams that want readable web, mobile and API automation, with a choice of managed cloud or self-hosted deployment.
