Logs that don't cool.

CRUCIBLE is an append-only log warehouse. Backed by S3, queried in sub-second, retained forever. One binary, no agents, no per-host pricing. Ship 4.1 PB/day on $0.04 per GB — the same logs you would have dropped on the floor of any other vendor.

Three things,
done honestly.

— what we ship · what we don't
— 01 / cheap

S3 is the database.

Cold tier sits on your own bucket. Hot tier is a thin in-memory index over the last seven days. No replication tax, no proprietary block storage, no "egress" surprise. $0.04 / GB stored. Forever.

— 02 / fast

Sub-second on billions.

Columnar segments, inverted indexes per field, query planner that prunes 99% of partitions before touching disk. p99 = 142 ms over 4.1 billion rows. Every commit benchmarks against a 4 PB synthetic corpus.

— 03 / open

OTLP, syslog, raw TCP.

Vector, Fluent Bit, OpenTelemetry collector — all first-class. No proprietary agent. No daemon running as root. The query layer is Apache-2 OSS. Cloud is optional. You can leave us and take your data.

THE FIRE goes
out — your
LOGS DO NOT.
