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.

A make replacement based on Jam, with more powerful features than the original Jam. Features dependency scanning, per-target viewpathing, and control flow. Distributes builds across multiple cluster machines for faster builds.

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.

A .NET based build tool. A replacement for make based on Ant.

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.

Open Source - A Make replacement written in Perl featuring hierarchical builds, dependency graph node triggers, no built in rules, PBS/Perl syntax for PBSfiles, a Perl API for the system, and shell or Perl build actions.

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 tiny command-line prefix tool that can track dependencies for a file automatically without the need for a Makefile.

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.

Open Source - A modular makefile system for multi-platform C++ development in Unix environment using GNU make 3.80 or higher, featuring modular makefiles and transparent handling of dependencies and sources of multiple projects.
