ReliaStats

Grab this when you need to run reliability engineering calculations without standing up your own stats backend. It handles Weibull and lognormal distribution fitting for failure data, calculates MTBF and MTTR metrics, and computes system availability for different configurations. The server also supports reliability block diagrams and system composition analysis, so you can model series, parallel, and k-out-of-n redundancy scenarios. Connects over streamable HTTP to ReliaStats' hosted endpoints, which means you're making API calls to their infrastructure rather than running local computations. Useful for building maintenance dashboards, failure analysis tools, or embedding reliability calculations into larger engineering workflows without importing heavy statistical libraries.
