Pharo is a new open-source implementation of Smalltalk.
Pharo's goal is to deliver a clean, innovative, open-source Smalltalk environment. By providing a stable and small core system, excellent developer tools, and maintained releases, Pharo is an attractive platform to build and deploy mission critical Smalltalk applications. Pharo is MIT licensed and is steered by a board of benevolent dictators. The board makes final decisions if no consensus can be reached within the community. Pharo fosters a healthy ecosystem of both private and commercial contributors who advance and maintain the core system and its external packages.
Pharo provides a pure object-oriented language and system that runs on all major platforms, a stable core system with unit tests, a clean look and feel full block closures, low memory footprint (in progress).
