Web-hosting companies that offer server-side Tcl

Even if they don't advertise it, most web hosts usually do have some version of Tcl installed. On this page, hosts that have received positive reviews from members of the Tcl community are prioritized. All links on this page as of 2014-03-15 have been verified not dead and still relevant.

Choosing a Web Host

Gerald Lester has written, "I find it important to be able to build my own shell and extensions -- the hosting service may not have the combination that you like or stay up to (or back on) the version you want or need."

Occassionally, hosting can be found simply by searching on google with 'mod_dtcl hosting' or similar queries.

Try Googling for linux virtual private server hosting or linux uml virtual server hosting.

FW: Hmm... can we spin this discussion into "how to choose a good Web host"? When I see "we have a Control Panel", I read: "we provide the means for newbies to manage everything more easily". But when I see a Control Panel and no SSH, I read: "we have clearly defined the limits of what you can do and expect you to have a lot of patience clicking things and waiting for them to (re)load in every single tiny goddamn change". Oh, and your browser had better be compatible with our control panel too...

A host that won't let users have SSH is most often afraid of what users can do with it. In other words, they acknowledge that they are not competent enough to run such service and maintain a good security level at the same time.

DRH: FWIW, I keep http://www.sqlite.org/ and http://tkhtml.tcl.tk/ and several other websites on a single user-mode-linux virtual machine, packaged and sold by http://www.linode.com/ . The service has been good for a couple of years now. I run CGI scripts using whatever version of TCL I want (currently 8.4.something).

CMcC seconds that. This very wiki runs on a linode, and I'd thoroughly recommend them.

stevel thirds that - another happy Linode customer

peterc fourths that. Recently signed up (July 2010) and I'm very impressed so far.


Doug 2008-01-29 2009-01-29 2014-03-14: I've used icdsoft.com for the past seven years. They have a very responsive tech support staff. In March 2014 they installed Tcl 8.6 (they keep Tcl 8.4 as well). (As of Jan 2009 they were running Tcl 8.4 & 8.3) [L1 ]

webfaction :

PYK: I've used icdsoft.com for years, and their support is second to none, but I've recently been using webfaction more because they provide an innovative layer of abstraction where each website is composed of multiple domains and applications. Each application typically gets its own instance of Apache httpd, Nginx, or any other needed program. They've been rock solid for the few years I've been using them. Their support, while not bad, is not as responsive as icdsoft, but because they give me more control, including my own Apache instance, I haven't needed to interact with them very much. They only provide Tcl 8.4, so be prepared to bring your own.


LES They're good because they are cheap and you get everything you will ever find in other hosts' packages and no ridiculous limits, like half a dozen POP3 boxes. They even let me edit my .qmail file, which is too precious a feature to me. The only thing you don't get much is support and I do have problems once in a while. Anyway, they run Tcl 8.3.


LES Another one to the list: rootr.net The whole thing sounds a bit too good to be true, but anyway...

LES 2005-04-18: that's been more than one year since I mentioned rootr.net here. I have been hosting my main site with them since then and I can say it is very good. OpenBSD, everything is very well kept and organized. Support is good too. They run some rather old version of Tcl, but also provide full SSH access and let me install my own Tcl and extensions in my home directory. The only bad thing is that their server is in Hong Kong. That makes e-mail and SSH considerably slow. But it still is a very good and *extremely* affordable host.


provides the RIVET Apache module enabled on its server from 2004-03-31. Experience on this provider is good overall and prices are amenable to non profit uses and high end as well.


PolarHome is a non-commercial, educative effort for popularization of shell-enabled operating systems and Internet services, offering shell accounts mail and other online services on all available systems (currently on Linux, OpenVMS, Solaris, AIX, QNX, IRIX, HP-UX, Tru64, FreeBSD, OpenBSD and NetBSD).

Here's a little sqlite database served with tclkit that Eric Amundsen has hosted there.


Todd Coram: has a Tcl 8.0 tclsh (although they advertise 7.6). They have been a pretty decent (and cheap) web host for me.

Tom 2004-04-2: Neosoft was bought out by Internet America but dynamis.net [L2 ] is still hosting NeoWebScript sites, in fact they're advertising it on the radio this week right along with PHP.

Dynamis of Houston offers Neowebscript web hosting for server-side TCL, and even offers secure (SSL) Neowebscript forms hosting with online credit card processing. They appear to have several customers already running the online portions of their major bricks-and-mortar operations on their service, all based on Neowebscript (server-side TCL) scripting:

The great earth mother of all web-hosting companies, does Tcl:

JJM 2009-09-02: Talked to one of the admins at Hurricane Electric and confirmed that they have Tcl 8.4.16 on their latest servers.

Here is a trivial tclsh cgi I just whipped up as proof of concept.

Oops! Looks like I need to talk to them about that...

Okay, I talked to Michael Bernardo at he.net, and he says that since all users get a shell account, they can compile their own tcl right there in their home directory and go to town!
