# Feature catalog — puppeteer/puppeteer

Scanned commit 2e45a3af43231cd658285e4da5e7f53e40f24edf (2026-10-02). Generated by codevetter codevetter 1.15.0 on 2026-10-02.

Source inspection; upstream code and tests were not executed.

The main user surface is the JavaScript automation API, complemented by browser-management commands and Angular tooling. The inspected APIs cover browser sessions, page interaction, network behavior, captures, and browser-specific controls. CDP and BiDi have differing capabilities, so feature availability depends on browser, protocol, and sometimes browser version. This catalog groups the investigated surfaces and does not claim exhaustive enumeration of every exported method.
- launch supports Chrome and Firefox launcher selection; connect attaches through exactly one of browserWSEndpoint, browserURL, a custom transport, or a Chrome channel. — [packages/puppeteer-core/src/node/PuppeteerNode.ts#L139-L162](https://github.com/puppeteer/puppeteer/blob/2e45a3af43231cd658285e4da5e7f53e40f24edf/packages/puppeteer-core/src/node/PuppeteerNode.ts#L139-L162) [packages/puppeteer-core/src/common/BrowserConnector.ts#L94-L109](https://github.com/puppeteer/puppeteer/blob/2e45a3af43231cd658285e4da5e7f53e40f24edf/packages/puppeteer-core/src/common/BrowserConnector.ts#L94-L109)
