Project history and usage
Sloth is a Prometheus SLO generator distributed as the `sloth` CLI by the Homebrew `sloth-cli` formula. It turns service-level-objective specifications into Prometheus recording and alerting rules, including multi-window, multi-burn-rate alerting.
Project history
The official repository describes Sloth as an easy way to generate Prometheus SLOs from a simple SLO spec. The GitHub repository was created in 2021, and the first GitHub release listed by the official API is v0.1.0 published on 2021-05-05.
The changelog shows the project growing from a focused CLI into a broader SLO toolchain: v0.10.0 added directory discovery for generated SLO files, v0.13.0 migrated rule generation to plugins, v0.15.0 exposed SLO generation as a Go library, and v0.16.0 added a server command and UI work.
Adoption history
Sloth fits the GitOps and Kubernetes observability audience: the official CLI docs say the generate mode only needs the CLI, making it useful for CI, scripts, and toolboxes.
Homebrew, MacPorts, and Nix package mappings in the input facts show adoption across common developer package managers, and the Homebrew formula API reported 545 installs-on-request over 365 days for the batch's lookup window.
How it is used
The documented quick start is `sloth generate -i ./examples/getting-started.yml`, producing Prometheus rules from an SLO specification.
The official CLI usage page says `generate` supports multiple spec types, including the default Prometheus rules output and Kubernetes Prometheus-operator rules output.
Why package nerds care
Sloth matters to package-manager users because it packages SRE practice into a single CLI binary: SLO definitions can live in repositories and CI systems rather than only inside dashboards or vendor SaaS.
It is also a modern example of observability tooling being shipped through developer package managers so teams can pin, upgrade, and run it in local and automated workflows.
