How we measure
A "browser" is a request whose user agent starts with Mozilla/5.0 and doesn't introduce itself as a bot. It's in costume when its TLS handshake (the JA4 fingerprint) isn't one a real Chrome, Edge, Firefox or Safari sends. Half a costume is a browser user agent that stops before naming any browser. Honest bots are user agents that say they're a bot, crawler or scanner, grouped by the name they give.
Best costumes
The user agents bots wore most, with a handshake no real browser sends.
