Match the reliability controls
Assess how each service handles objectives, error budgets and reliability scorecards in relation to your measurement practices. OpenSLO does not list SLO management; Sloth does.
Check service limits as well, since limits can affect how you define and monitor objectives.
Check automation and reporting
Automation for workflows and SRE reporting may influence daily operations. Confirm which controls are included and how they fit your process before selecting a platform.
Verify platform and deployment fit
Support spans web, API, Linux, macOS, Windows and iOS across the listed platforms.
Compare the deployment model with your environment, and check the licence when open-source code matters. OpenSLO and Sloth use open-source pricing, while Pyrra offers a free plan.
