ostream.dev

Stream a pipe over HTTP.

Pipe output from one machine, tail it from another. A curl on both ends — no SDK, no daemon.

on one machine

make 2>&1 | curl -T - \
  -H "Authorization: Bearer $TOKEN" \
  https://ostream.dev/s/build

on another

curl -N \
  -H "Authorization: Bearer $TOKEN" \
  https://ostream.dev/s/build

Details

Line-oriented. Multiple producers can write to the same stream; lines interleave by arrival order. One consumer at a time — a new one kicks the previous (configurable).
Drain semantics. Lines are removed from the buffer once delivered, so the consumer sees each line exactly once.
Bounded buffers, short TTLs. Old lines age out. Your account's plan sets the limits.
End-to-end encryption (optional, via the CLI). ChaCha20-Poly1305 per line — the relay never sees plaintext.
EOF signalling. A producer can mark a stream terminated with ?eof=1, and a consumer with --once exits cleanly when it arrives. Works nicely for one-shot pipelines.

Install the CLI

brew install ostream-dev/tap/ostream

Or go install github.com/ostream-dev/ostream-cli/cmd/ostream@latest. Features: reconnection, encryption, file I/O, and all the query params as flags.
