SRE Simulators
Interactive tools to model your SLOs, alerts, and risks — no setup, runs entirely in your browser.
Each simulator is paired with an explanatory article. Explore the concepts, then experiment with the numbers.
SLO
SLO Simulator
Calculate your error budget and visualise time-to-exhaustion at every burn rate.
≤
Realistic SLO
Estimate the maximum achievable SLO given your dependencies' SLAs.
BR
Alert Noise Reducer
Find the optimal long/short windows to reduce false positives.
#
Cardinality Budget
Estimate your Prometheus time series count and required RAM.
MT
MTTR/MTTF Optimizer
Calculate your real availability and the impact of reducing MTTR.
DR
Dependency Risk Scorer
Score the risk of each dependency and identify the weakest link.
