01Backpressure-aware buffering
When a sink slows down, the pipe holds the line instead of dropping it. Spill to disk above a threshold and replay once the downstream recovers.

Tail anything, shape it on the fly, route it wherever you need.
Coldoutreach Explee is a single-binary log pipeline that lives in your shell. Pipe raw streams in, apply filters and parsers without a config server, and fan out to the sinks your team already runs. No agents to babysit, no YAML sprawl.
# grab the binary and point it at a stream
$ curl -fsSL https://coldoutreach-explee.com/install.sh | sh
$ Coldoutreach Explee tap --source /var/log/app.log
✓ attached · buffering at 12k lines/s · sink: stdout
$ Coldoutreach Explee pipe --filter level=error

what makes it fast
One binary that fits the way you already work
02Parsers without a daemon
JSON, logfmt, syslog and regex captures resolve inline. Define a parse rule on the flag line and it applies on the next byte — no restart, no central config.
03Fan-out to real sinks
Forward the same stream to S3, Loki, an HTTP collector and your screen at once. Each route keeps its own buffer and retry budget.
04Checkpoints you can trust
Every tap records a byte offset on disk. Kill the process, redeploy, restart — it resumes exactly where it stopped, no duplicated lines.
