InstallBuilder vs NSIS

InstallBuilder provides tools for packaging, deploying, and updating software. From one project file and build environment, it creates native cross-platform installers, RPM and Debian packages, and CD or DVD media. Output options also include self-contained executables, DMG, and ZIP. Installers can present a graphical interface, run in text mode, or install silently. Teams can use an XML project format with source control integration and external scripts, and automate builds through the command-line interface. Installers are single-file executables with built-in LZMA compression and no external dependencies; optional downloadable components are fetched only when selected during installation. The product supports automatic updates, Windows and OS X installer signing with PKCS#12 or PFX certificates, and password-protected encrypted payloads. Platform-specific licenses, Professional and Enterprise editions, and site licenses are listed. Prices start at $995, paid once, with one year of support and updates included. A fully functional evaluation copy is available through the download form.

NSIS is a free programmer’s tool for creating self-contained Windows executable installers and uninstallers. Its scripting language handles variables, functions, string manipulation, and custom installation logic, including installing or removing software, changing system settings, and extracting files. Developers can choose classic or modern wizard interfaces, create custom pages, and provide multiple interface languages, including right-to-left languages. Compression options include ZLib, BZip2, and LZMA. Plug-ins can extend installer tasks and interfaces, download files, make internet connections, or patch existing files. The compiler preprocessor can combine projects, automate builds, and produce lite or full variants. Installers can support command-line packaging, silent installation, and CRC32 self-checking. The compiler can be built on POSIX systems such as Linux and BSD, but generated installers run on Windows. Documentation links to a FAQ, wiki, and forum.
