About ActiveTcl

Enterprise-grade, pre-compiled programming language for developing applications in Tcl.

ActiveTcl is a precompiled, cross-platform, secure way for developers and engineers to work with Tcl from desktop to production to embedded in systems. To ensure that enterprises can safely adopt open source software (OSS) like Tcl in their mission critical systems, ActiveState has been in the business of providing supported, community-derived OSS language distributions for more than 20 years. When developing applications or writing scripts, 97% of the Fortune 1000 think of ActiveState. Getting started with coding in Tcl easy - ActiveTcl is optimized to run consistently across your operating systems, with popular modules precompiled so you don’t have to do the plumbing to get started. The ActiveTcl distribution features popular third-party modules, all of which have been carefully curated for license compliance and stale-dated components that may arise from lack of community support. Only then are the modules incorporated into the distribution through a process of rigorous testing, patching and optimization to ensure compatibility and performance.
