Open Source - A-A-P is an experimental make tool. Features include a special AAP makefile syntax, automated dependency support for Unix C programs, and a GUI interface written in Python.

Freeware - A make replacement that uses an XML description language instead of makefiles, and that executes build actions using Java objects instead of shell commands.

Freeware - A Make replacement with a simple and high-level target language. It supports build variants, and several different compilers and tools.

Open Source - A software build system implemented on top of GNU make featuring position-independent non-recursive multi-makefile include-based structure, complete inter-project dependency tracking, and extensible translator framework.

Freeware - A make replacement written in Perl featuring MD5 file content and build signatures, dependency scanning, viewpathing for source and derived files, multidirectory builds, and Perl build actions.

Freeware - A make replacement featuring file fingerprints, dependency scanning, viewpathing, parallel threads, distributed rsh builds, cross compiling, and build actions in the "cook" description language.

A make replacement that distributes builds across multiple cluster machines for faster builds. Features plug-compatibility with GNU Make and Nmake.

Freeware - A make program featuring pattern-matched viewpaths, parallel threads, multiple platforms, conditional directives, makefile regeneration, and an advanced Make description language.

Freeware - A make replacement featuring dependency scanning, per-target viewpathing, parallel threads, multiple platforms, variant builds, and control flow statements in the Jam description language.

Freeware - A make program written in Java, featuring a traditional make description language and shell command target actions.

Freeware - A build system based on GNU Make and GNU M4. It automates many mundane tasks including creating Doxygen documentation.

Chambeau - A modified GNU make that uses the MPI Message Passing Interface for excellent scalability on multiple machines. Authors now say use 'GNU Make -j' instead.

Freeware - Not Ant is like Ant, but uses C# and .NET technologies.

Lucent - Features dependency scanning, viewpaths, parallel and distributed rsh execution, a coshell, compiled makefiles, C preprocessor, variable editing, and a powerful Make rule language.

Freeware - A make replacement featuring dependency scanning, viewpaths, distributed rsh execution, cached derived files, variant builds, conditional directives, and an Odin rule language.

Opus - A multiplatform make featuring dependency scanning, suffix-specific viewpaths, extended command and macro modifiers, CPP preprocessor directives, and iterators in the Make rule language.

Freeware - A modified GNU make that uses the Oakridge PVM Parallel Virtual Machine to perform parallel distributed builds.

Freeware - A make replacement like Cons, written in Python and featuring MD5 file signatures, dependency scanning, parallel build threads, viewpathing, multidirectory builds, and Python build actions.

Freeware - A make replacement, written in Python featuring global dependencies view, extensible dependency scanning, parallel build threads, multidirectory builds, automatic cleaning and extensibility via Python classes.
