2018-02-16 Warning: the person that updated this page stopped doing this more as ten years ago. Sometimes people update the page, but it really is not a page any-more that does justice to the usage of Tcl.

EMJ 2018-02-16 : How can you say this? Have you looked at the page history (and that of Companies That Use Tcl which was combined with this page)??

CecilWesterhof 2018-02-16: From the newsgroup:
> Also the page of companies using Tcl seem to reference old applications

Well, this is true because the person(s) who used to update that page
stopped doing so over 10 years ago.

So I thought it a good idea to warn people about this.

If someone knows a lot about the usage of Tcl and is willing: maybe this person could become the torch-bearer?

SEH This page is frequently updated with new entries. Like every other page, it is community-edited. Updaters have prioritized adding new links over removing old ones. If some of the links are old, it is because that is an inherent issue with a wiki that has been around for 20 years. If you think old links are a problem, it is wiki-wide. The wiki remains a valuable resource nonetheless.

Who Uses Tcl is a list of notable projects, products, organizations that use Tcl Many of the links are to other pages on this wiki that describe the variety of "mission-critical", "enterprise-class", or other ways that Tcl is being employed.

Discussion  edit

The page, Companies That Use Tcl was folded into this page on 2013-03-08. There may be useful information in the history of that page.

Several years ago, at a time before Tcl was well-known as a "mission-critical"-grade product, CL maintained Cameron Laird's personal notes on commercial aspects of Tcl. There's still useful information there, but also a lot of dead links. The Developers Exchange front page [1] used to point to several interesting industrial uses of Tcl.

very nice, the best marketing way
