fstrm is an optimised implementation of Frame Streams as a C library and several tools built on top of it.

Frame Streams is a light-weight, binary-clean protocol that allows for the transport of arbitrarily-encoded data payload sequences with minimal framing overhead---just four bytes per data frame. It does not specify an encoding format for these data frames and can be used with any data serialisation format that produces byte sequences, such as Protocol Buffers, XML, JSON, MessagePack, YAML, etc.

Frame Streams can be used either as a streaming transport over a reliable byte stream socket (TCP sockets, TLS connections, AF_UNIX sockets, etc.) for data in motion, or as a file format for data at rest.
