Reliability Engineering Python Packages

reliability

Reliability engineering toolkit for Python - https://reliability.readthedocs.io/en/latest/

chaostoolkit-lib

The Chaos Toolkit core library

chaostoolkit

Chaos Engineering Toolkit & Orchestration for Developers

surpyval

A Python package for survival analysis. The most flexible survival analysis package available. SurPyval can work with arbitrary combinations of observed, censored, and truncated data. SurPyval can also fit distributions with 'offsets' with ease, for example the three parameter Weibull distribution.

mnfst

Manifest SDK for Python. See every API call your app makes, heal the ones that fail, and know what will break next.

faultlib

Programmable network fault injection

shadowbox

Model the system. Experiment safely. Deterministic what-if simulation for backend architectures — CLI, API and dashboards. Python + TypeScript, local-first, no paid services.

iaes

IAES — Industrial Asset Event Standard. A vendor-neutral event specification for industrial asset measurements, diagnoses, and maintenance intents.

actseal

Test frozen model decision policies with risk/coverage bounds, provider-fault checks and offline replay.

aws-chaos-engineering-framework

Break AWS safely before reality does: enterprise-grade FIS orchestration, GovCloud guardrails, rollback, and audit-ready evidence in one Python file.

pirao

pirão — Probabilistic Inference for Reliability Analysis from Observed data: Bayesian reliability with Stan, sibling of farofa and faultree

farofa

failure and repair simulation optimization framework

agentic-reliability-framework

ARF is an agentic reliability intelligence platform that separates decision intelligence (OSS) from governed execution (Enterprise), enabling autonomous operations with deterministic safety guarantees.

faultree

A simple fault tree analysis library for Python.

choircert

A distribution-free conformal prediction certification layer for safety-critical ordinal classification. Guarantees contiguous prediction sets, marginal/group-conditional validity, true-label coverage under banded reporting noise, and severity-weighted risk control (fatal-omission bounds) with an explicit additive slack budget.

inverse-canopy

An inverse estimation technique for back-fitting conditional/functional event probability distributions in an event tree to match target end-state frequencies.

reliopt

Reliability-constrained, multi-objective optimization for LLM and agent programs

tracecore

Deterministic runtime for agent evaluation

llm-reliability

Local-first root-cause diagnosis engine for LLM, RAG, and Agent failures — deterministic, evidence-backed, zero API keys required.

agentproof-sim

Stateful simulation and fault-injection testing for tool-using AI agents.

criticality-spectrometer

Single-point-of-failure and blast-radius analysis with time-to-substitute curves for AND/OR dependency systems.

toolgauntlet

Deterministic reliability testing for tool-using AI agents

reliafy-client

Open-source reliability engineering — fit life distributions, build reliability block diagrams, and optimise maintenance. Self-hostable (AGPL-3.0).

relistats

Computation of Reliability Statistics: Reliability, Confidence, Assurance
