Squeakbit 5.1 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally designed by Squeak Project.
The software lies within Developer Tools, more precisely Debugging Tools. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software.
From the developer:
Squeak is an open-source Smalltalk programming system with fast execution environments for all major platforms. It features the Morphic framework, which promotes low effort graphical, interactive application development and maintenance. The Squeak Wiki collects useful information about the language, its tools, and several projects.
