Tool Open source
satmux is a pure-Python TCP multiplexer and HTTP/TLS relay for high-latency geostationary satellite inflight Wi-Fi. A local client maintains a pool of persistent, non-443 TCP connections to a Linux VM near the satellite ground station, using BBR, 1280-byte MSS, and zlib compression; streams are scheduled across the carriers to avoid repeated handshake delays and cabin :443 proxy failures. It exposes local SOCKS5 and HTTP CONNECT proxies, as well as a 1-RTT encrypted ground-fetch path that performs DNS, verified TLS 1.3, redirects, and response compression near the origin network. The repository also includes routing for Git and the gh CLI through a local Unix socket and macOS setup scripts. It uses only the Python 3 standard library, requires an authenticated cabin Wi-Fi session and a separately rented ground VM with an open TCP port, and is licensed under MIT.

A pure Python tool that speeds up slow in-flight Wi-Fi on geostationary satellite links by keeping persistent connections to a cloud server near the ground station, compressing and signing traffic, and exposing it locally as a SOCKS5 or HTTP proxy.
