In their own words
cargo-fuzz
cargo-fuzz is a Cargo subcommand for fuzzing Rust code. It invokes libFuzzer through the libfuzzer-sys crate rather than acting as a fuzzer itself. Start a crate with `cargo fuzz init`, add a target with `cargo fuzz add `, then use `cargo fuzz run ` to search for bugs. The tool can reduce a failing input with `cargo fuzz tmin` or trim a corpus with `cargo fuzz cmin`; `cargo fuzz coverage` generates source-based coverage information in version 0.10.0 or newer. Documentation also covers structure-aware fuzzing and Cargo feature options, plus a GitHub Actions workflow for building and running targets in CI. It supports Linux, macOS and Windows, with documented systems including x86-64 Linux, x86-64 and Apple-Silicon macOS, and Windows with LLVM sanitizer support. Windows programs can also be fuzzed with MSVC AddressSanitizer. Installation is documented as `cargo install cargo-fuzz`. It requires nightly Rust and a C++11-capable compiler. The project is free and distributed under the MIT and Apache License 2.0.
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.
