COMPUTER USE / COMPARE

Playwright vs Selenium

Both are deterministic browser automation frameworks. Choose around your browser matrix, language stack, existing tests, and execution estate—not an AI-agent label.

Shared layer; different tradeoffs.

Both are deterministic browser automation frameworks. Choose around your browser matrix, language stack, existing tests, and execution estate—not an AI-agent label.

Choose by the work

CHOOSE PLAYWRIGHT WHEN

Consider Playwright for a new deterministic browser suite when its supported environments and test patterns fit the project.

Read the evidence →

CHOOSE SELENIUM WHEN

Consider Selenium when existing WebDriver code, language tooling, browser requirements, or Grid operations are important assets to preserve.

Use both when: They can coexist during a scoped migration. Keep fixtures and outcome definitions consistent, then retire duplicate coverage deliberately.

Meaningful differences

Playwright exposes its own browser automation and testing APIs; Selenium’s core automation model centers on WebDriver.
Selenium documents WebDriver, IDE, and Grid as distinct project components, so an existing Grid estate is part of a migration decision.
Playwright’s locator, browser-context, and test patterns shape test isolation and assertions; Selenium integrations have their own driver and runner conventions.
Neither framework supplies a general autonomous planning loop by itself. Adding an agent changes the stack and requires separate policy and outcome validation.

Fit by workflow

Existing enterprise test suite

Price the migration and validate the required browser/driver matrix before rewriting.

Agent workflow acceptance tests

Either can provide explicit checks; choose the framework your team can maintain.
