In their own words

EvoMaster

EvoMaster is a free, open-source tool that uses fuzzing to generate system-level tests for web and enterprise applications. It targets REST, GraphQL, and RPC APIs, including gRPC and Thrift. Black-box mode works with APIs in any programming language, while white-box mode analyzes JVM bytecode. Generated tests can be JUnit 4 or 5 in Java or Kotlin, or suites in Python or JavaScript. More than 30 oracles check issues including HTTP 500 responses, schema mismatches, BOLA, and SQL injection. White-box testing can analyze SQL and MongoDB interactions with PostgreSQL, MySQL, H2, and MongoDB support. Authentication accepts headers and cookies, including tokens or cookies obtained from a login endpoint. REST testing requires OpenAPI 2.0, 3.0, or 3.1. PyPI is the recommended installation route, with Docker and an uber-fat JAR also available. EvoMaster runs on Linux, macOS, Windows, and self-hosted environments, and integrates with GitHub Actions through a custom action.

Its tools support dependency resolution, lockfiles, workspaces, private registry authentication, and offline installation. It runs on Linux, macOS, Windows, and other operating systems through Node.js installers or version managers. For private packages, the Paid user account plan is $7 a month; Pro is also $7 a month for individual creators, while Teams is $7 per user per month for teams and organizations.
