Available in

JavaScript / ECMAScript

Browser-native RegExp. Default if you don't pick.

Python (re)

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic

([^=;\s]+)=([^;]+)   (flags: g)

Raw source: ([^=;\s]+)=([^;]+)

How it works

([^=;\s]+) captures the cookie name — characters that aren't equals, semicolon, or whitespace. = is the literal separator. ([^;]+) captures the value — everything up to the next semicolon, allowing spaces and special chars inside the value. Repeats globally to capture every cookie.
