relay

a single-binary cli that tails, filters, and diffs structured logs across clusters — because grep deserved a promotion, not a replacement.

why

every team i joined had the same ritual: four terminals, four kubectl contexts, and a prayer. relay collapses that into one command that streams structured logs from every cluster you can reach, with filters that survive reconnects.

notes

  • one static binary, no agents, no server component
  • filter expressions compile to a small vm — the hot path allocates nothing
  • relay diff replays two time windows side by side, which has settled more "it worked yesterday" arguments than any dashboard

still the tool i reach for first during an incident.
