Sheaf is time-series storage that keeps every reading at full resolution, for as long as you need it.
Start a free clusterMonet painted the wheat stacks outside his house at Giverny around twenty-five times in 1890 and 1891, at every hour and in every season. Sheaf keeps your metrics the way he kept that field: every moment, nothing averaged away.
Point agents, sensors and services at one endpoint. Sheaf takes Prometheus remote write, OpenTelemetry and line protocol, and files late data under its own timestamp.
Readings are kept at the resolution they arrived. Columnar compression keeps per-second data small enough to hold for years, so you never roll it up and lose the detail.
Query in SQL or PromQL. Compare this morning with the same morning three winters ago, without building a rollup table first.
Storage is billed per gigabyte after compression. Ingest and queries are free, and a free cluster keeps thirty days of data with no end date.
