[Compare](https://cdpfleet.com/docs/compare) / browsers # Chrome vs Edge Two real Chromium browsers on the fleet, measured side by side: identical engine, identical HTTP/2 and header order, and exactly three things a site can tell apart — the user-agent token, the client-hint brand and one TLS extension. [Google Chrome](https://cdpfleet.com/docs/browsers/chrome) [Microsoft Edge](https://cdpfleet.com/docs/browsers/edge) [Chrome](https://cdpfleet.com/docs/browsers/chrome) and [Edge](https://cdpfleet.com/docs/browsers/edge) on the fleet are the official Google and Microsoft builds for Linux, both on Chromium 154 at the time of measurement, both driven with the Playwright `chromium` client. Edge is Chromium with Microsoft's services and UI on top; for automation almost none of that UI exists. The interesting question is what is left that a server can see — and the answer is short enough to list. ## As a developer: driving them | | Google Chrome | Microsoft Edge | | --- | --- | --- | | Build and versions | Official Google build. `channel`: stable (154), beta (156), dev (157); `version` pins previous majors (153, 152 today). | Official Microsoft build. `channel`: stable (154), beta (155), dev (156). No pinned previous majors. | | Playwright client, options | `chromium` 1.60. The common options plus `channel` and `version`. | `chromium` 1.60. The common options plus `channel`. | | Rendering, codecs, PDF, device emulation | Chromium 154 with proprietary codecs (H.264, AAC) and Widevine, unlike Playwright's open-source Chromium. PDF in headless; mobile emulation works. | The same Chromium 154 and the same proprietary codecs; PDF and emulation the same (measured: every Playwright feature probe identical). | | What Edge adds for a user | — | Collections, vertical tabs, the sidebar, Copilot, Microsoft account sync — browser UI that is not part of a page and not reachable through Playwright. For a script, Edge is Chrome with a different name. | | Threads, speed | 2 headful, 1 headless. Timings in the table are proxy noise. | Same. | ## As a scraper: what the site sees | | Google Chrome | Microsoft Edge | | --- | --- | --- | | User agent | `… Chrome/154.0.0.0 Safari/537.36` | `… Chrome/154.0.0.0 Safari/537.36 Edg/154.0.0.0` — the only difference in the string. | | Client hints (`sec-ch-ua`, `navigator.userAgentData`) | Brands `Chromium 154`, `Google Chrome 154`, plus the GREASE token. | Brands `Chromium 154`, `Microsoft Edge 154`, plus the GREASE token; `fullVersionList` carries Edge's own build (154.0.4258.62) next to Chromium's. | | TLS | JA4 `t13d1517h2_8daaf6152771_…` — 19 extensions. | JA4 `t13d1516h2_8daaf6152771_…` — 18 extensions: Edge's ClientHello omits one extension Chrome sends. Same cipher suites (the middle hash matches), different full JA4 and peetprint. | | HTTP/2 and headers | Akamai fingerprint `1:65536;2:0;4:6291456;6:262144|15663105|0|m,a,s,p`; header order `:method :authority :scheme :path sec-ch-ua …`. | **Identical** — same SETTINGS, same WINDOW\_UPDATE, same pseudo-header and header order (measured). | | JavaScript surface | Chromium 154: same plugins (5), same WebGL (SwiftShader on the fleet), same canvas hash, same feature set, `webdriver` false. | **Identical** on every probe except the UA-derived values (measured). | | Who runs it | About two thirds of desktop users; on Linux, the dominant browser. | A few percent of desktop users, mostly on Windows; Edge on Linux (`X11; Linux x86_64 … Edg/`) is a small cohort — a consistent one, since it is a real build, but small. | | bot.sannysoft.com | 1 of 57 red: "WebGL Renderer" (the SwiftShader string). | The same single red. | ## Which to pick - **Chrome** by default: the largest cohort, the most versions and channels (including pinned majors for reproducing a site's behaviour on an older release), and the browser most sites are tested against. - **Edge** when the target treats Edge differently — Microsoft properties and sites that gate features on the `Edg/` token or the `Microsoft Edge` brand — or when you want a second genuine Chromium identity (different UA, brand and JA4) without leaving real browsers. Keep the platform plausible: an Edge user agent on Linux is rare; use it where it fits. - **Not for diversity at scale:** alternating Chrome and Edge changes three fields and nothing else — same HTTP/2, same canvas, same GPU string. For identities that differ at the device level, see [Camoufox](https://cdpfleet.com/docs/browsers/camoufox). ## Measured on the fleet (2026-10-06) One headful launch of each through the same proxy; both official Linux builds on Chromium 154. The TLS difference is stable per build; the timing difference is one slow proxy exit during Chrome's run. ### Launch and cost Single run; timings depend on the proxy and on fleet load. | | Google Chrome | Microsoft Edge | | --- | --- | --- | | Launch body | {"headless":false} | {"headless":false} | | Threads used | 2 (linux\_headful) | 2 (linux\_headful) | | Browser version | 154.0.8037.97 | 154.0.4258.62 | | Launch request → browser ready | 0.7 s | 0.6 s | | Playwright connect | 0.3 s | 0.1 s | | Load example.com | 5.5 s | 0.4 s | | Load tls.peet.ws/api/all | 1.4 s | 1.6 s | ### What the network sees From tls.peet.ws/api/all, requested by the browser itself.

Everything an anti-bot system reads beyond that — HTTP/2, header order, canvas, WebGL, feature set — is byte-for-byte Chromium 154. That makes Edge a safe, cheap second identity when a site cares which badge it sees, and a pointless one when it doesn't. --- Source: https://cdpfleet.com/docs/compare/chrome-vs-edge · Markdown: https://cdpfleet.com/docs/compare/chrome-vs-edge.md · All docs for AI tools: https://cdpfleet.com/llms.txt
