The prebuilt frpc binary (fatedier/frp, linux/x64) that the corsair dev tunnel spawns.
Don't install this directly — corsair lists every platform's binary as an optionalDependency and your package manager installs only the one matching your OS/CPU (the esbuild/Turbopack model). The binary is materialized at publish time by scripts/prepare-frpc-packages.mjs.
frp is redistributed here under Apache-2.0 — see LICENSE.frp and NOTICE.
