Kurtosis OSS is an open‑source engine that lets developers define and launch multi‑node blockchain devnets using a declarative YAML file. It provides container‑based, modular packages—including pre‑built modules for Ethereum, Polygon CDK, Blockscout, and others—to deliver reproducible environments that integrate with CI/CD pipelines.

Problem
Blockchain infrastructure teams often spend extensive time configuring, provisioning, and maintaining isolated devnets for testing protocols and applications. Existing tools are either heavyweight, lack modularity, or require manual setup, leading to slow iteration cycles and inconsistent environments.
Solution
Kurtosis OSS is an open‑source development environment engine that abstracts blockchain infrastructure as composable packages, similar to Docker Compose. Users define a devnet in a declarative YAML file and launch a private, portable, and modular network with a single command. A curated package catalog provides ready‑made deployments for Ethereum, Polygon CDK, Blockscout, World Chain, and more, while developers can create and share custom packages for any blockchain component. The engine isolates each service in containers, ensuring reproducible environments across machines and CI pipelines. All components are released under the Apache 2.0 license, enabling unrestricted use and community contributions.
Target Audience
Primary users are protocol engineers, platform teams, and DevOps professionals who need fast, reliable blockchain devnets for development, testing, and continuous integration.
