Edge vs Brave

Two Chromium 155 forks with the same TLS and HTTP/2 fingerprint: Edge names itself in the user agent and reports its real machine; Brave hides in the user agent but not the client hints, farbles cores, memory and screen, and drops Topics and Fenced Frames.

Microsoft Edge Brave

Edge and Brave are the two Chromium forks people reach for when "not Chrome" matters — Edge because it's the second most common desktop browser, Brave for its privacy defaults. On the fleet both run Chromium 155.0.8059.40, measured the same night. Underneath, a server sees the same network fingerprint; the differences are in how each one names itself and how honest it is about the machine it runs on. For each against Google Chrome, see Chrome vs Edge and Chrome vs Brave.

As a developer: driving them

	Microsoft Edge	Brave
Version on the fleet	Edge 155.0.4283.45 on Chromium 155.0.8059.40; `channel` beta (156) and dev (157).	Brave on Chromium 155.0.8059.40; `channel` beta. No dev channel.
Playwright client, options	`chromium` 1.60; `channel`, `cdp`, `live_view`, `screen_size`, `keep_alive`, `profile`, `start_url`.	The same list.
Playwright features	Main-world evaluate, console events, init scripts, routing, screenshots, PDF, device emulation, tracing — all work (measured).	All the same, all working (measured).
Web platform	Chromium 155 including Google's Topics API, Fenced Frames and `navigator.connection` (measured).	Chromium 155 without Topics, Fenced Frames and `navigator.connection` (measured) — Brave removes them.
Threads	2 headful, 1 headless.	Same.

As a scraper: what the site sees

	Microsoft Edge	Brave
User agent	`… Chrome/155.0.0.0 Safari/537.36 Edg/155.0.0.0` — names itself.	`… Chrome/155.0.0.0 Safari/537.36` — the plain Chrome string.
Client hints	Brands `Microsoft Edge 155`, `Chromium 155`; full versions `155.0.4283.45` and `155.0.8059.40`.	Brands `Brave 155`, `Chromium 155`; full versions reduced to `155.0.0.0`. Hiding in the user agent doesn't help against `Sec-CH-UA`.
Headers	Chromium's order: … `accept`, `sec-fetch-site`, `sec-fetch-mode` …	Adds `sec-gpc: 1` (Global Privacy Control) before the fetch metadata.
TLS	JA4 `t13d1516h2_8daaf6152771_806a8c22fdea` — 16 ciphers, 18 extensions.	The same JA4 and the same peetprint (measured). The JA3 hash differs between any two runs (extension order is randomised), so don't compare JA3.
HTTP/2	SETTINGS `1:65536;2:0;4:6291456;6:262144`, WINDOW_UPDATE 15663105.	Identical (measured).
Machine it reports	The server's own: 36 cores, 32 GB, a 1280×720 screen, one canvas hash.	Farbled: 51 cores, 8 GB, a 1366×768 screen and a different canvas hash — values that change between sessions and sites.
Languages, plugins	`en-US, en`; 5 plugins.	`en-US` only; 7 plugins.
Bot checks	bot.sannysoft.com: only "WebGL Renderer" flagged (SwiftShader on a GPU-less server).	The same single flag (measured).

Which to pick

Edge when the site should see a mainstream, consistent browser that isn't Chrome: a real brand in both the user agent and client hints, full version numbers, no extra headers and a machine that stays the same from visit to visit.
Brave when a fingerprint that won't hold still is worth more than blending in — cross-session device tracking gets new cores, memory, screen and canvas each time.
Neither differs on the wire: the TLS and HTTP/2 fingerprints are the same, so a block based on JA4 or HTTP/2 settings treats them alike. The difference is everything the page can read.
Brave's farbling can be implausible: 51 cores is an odd number for a desktop. If a site scores consistency, Edge's honest values may look more normal.

Measured on the fleet (2026-10-14)

One headful launch of each through the same proxy, probed from inside a page and via tls.peet.ws.

Launch and cost

Single run; timings depend on the proxy and on fleet load.

What the network sees

From tls.peet.ws/api/all, requested by the browser itself. JA3 hashes change between runs of the same build (GREASE), so compare JA4 and the HTTP/2 fingerprint.

Edge and Brave are the same Chromium 155 on the wire. Edge tells the page the truth about itself and its machine; Brave tells the user agent a white lie, the client hints the truth, and makes up the machine.

Both cost the same thread on the fleet.
