In their own words

EvoMaster

EvoMaster automatically generates system-level tests for web and enterprise applications by fuzzing APIs. It targets REST, GraphQL, and RPC APIs, including gRPC and Thrift. Black-box testing works across implementation languages; white-box testing is available for APIs compiled to the JVM, such as Java and Kotlin. The tool evolves test cases using evolutionary algorithms, dynamic program analysis, and AI heuristics to improve measures such as code coverage and fault detection. Its project describes more than 30 fault-detection oracles, covering issues such as HTTP status problems, schema mismatches, BOLA, and SQL injection. Generated results can include JUnit 4 or 5 tests in Java or Kotlin, Python or JavaScript test suites, and an interactive HTML report by default. White-box testing supports PostgreSQL, MySQL, H2, and MongoDB communications and can generate database initialization. Authentication headers and cookies are supported, as is dynamic credential retrieval through configured login endpoints. EvoMaster is free, has no telemetry, and says it needs no external internet services beyond the application under test. It can run on Linux, macOS, Windows, or self-hosted; PyPI is the recommended installation route, with a JAR and Docker image also available.

Fuzzinator

Fuzzinator is a free, open-source framework for automating fuzzing jobs against software under test. It runs test generators, stores distinct issues, reduces failing test cases, updates targets and schedules jobs across targets and generators without overloading the workstation. Configuration files and Python snippets let users customize workflows; built-in components handle common scenarios.

Its interfaces include an interactive Web UI, an interactive Text UI for Linux and Mac OS X, and a line-based dump mode for consoles on every platform. Issues and execution statistics are stored in MongoDB, with the documented default URI set to mongodb://localhost/fuzzinator. Reporting to trackers such as Bugzilla or GitHub is optional and must be configured. The framework includes only an example random content generator, so users may need external generators or custom components. Documented requirements are Python 3.10 or later and MongoDB 3.6 or later; Java SE 7 is optional for the Picireny reducer. The documentation lists Linux, macOS and Windows among tested platforms.
