Like Prometheus, but for logs!

Grafana Loki is a set of components that can be composed into a fully featured logging stack.

Unlike other logging systems, Loki is built around the idea of only indexing metadata about your logs: labels (just like Prometheus labels). Log data itself is then compressed and stored in chunks in object stores such as S3 or GCS, or even locally on the filesystem. A small index and highly compressed chunks simplifies the operation and significantly lowers the cost of Loki.

> **Note:** You can use [Grafana Cloud](/products/cloud/features/#cloud-logs) to avoid installing, maintaining, and scaling your own instance of Grafana Loki. The free forever plan includes 50GB of free logs. [Create an account to get started](/auth/sign-up/create-user?pg=docs-loki&plcmt=in-text).
