Millions of developers trust Tcl for rapid prototyping, scripted applications, GUIs, testing and more. It runs in numerous Cisco routers and in various network management tools. Because Tcl is an open source programming language, it can help cut up-front project costs. 

But Tcl alone may not help you meet your business goals.

Like most open source projects, Tcl isn't quality-assured or commercially supported. So it may not be safe for essential business applications. Don't let Tcl fail your internal systems and cost your business in lost revenue.

Cisco, Ixia, and Agilent are just a few of the companies that trust ActiveState for development, management and distribution solutions for fail-safe Tcl.

ActiveTcl is the industry-standard, commercial-grade Tcl distribution used by millions of developers around the world for fast, easy Tcl installation, and quality-assured code. Whether you're using Tcl for vital applications or in open source projects, ActiveTcl offers worry-free implementation and significant time savings over open source Tcl for installing and managing common Tcl modules. ActiveTcl comes precompiled for out-of-the-box installation and includes not only core Tcl and Tk, but dozens of popular extensions, the Tcl Package Manager (Teapot), and complete documentation.
