This page provides a list of Lisp-friendly web hosting services, i.e. companies or organizations providing services or online tools that make it possible -- or easier -- to deploy web-based Lisp applications. Information and comments (features, reliability, costs, etc.) by users of such services are particularly appreciated.

Warning: There is a known problem with Xen 3.0 on 64 bit machines (which many providers like Slicehost are using). Just starting sbcl will send it into 99% CPU usage and you'll be unable to kill -9 it, a forced reboot is the only way to fix it. Xen 2 and 3.1 do not suffer from this bug, and is used at The Tech Co-op specifically for this reason.

The workaround is to use 32 bit sbcl binaries, see this forum post on the issue

Focus is on Lisp friendliness. Sites providing access to PHP are a dime a dozen, we are interested in Lisp here.

www.tech.coop Services Co-operative

We offer Lisp hosting and other hosting services on a not-for-profit basis. Prices are determined by server use, and can be as low as $17.50 CAD monthly for a Lisp package on our virtual hosting platform. Your choice of lisp implementation, web server, mod_lisp or Pound.
Also, we now have Virtual Private Servers running under Xen if you need something more, $35 CAD for 128mb. Support packages are available specifically for lisp developers, at a discount from our normal rates.
Contact Drew Crampsie or /join #tech.coop on irc.freenode.net for details.

The "arpa" membership option also provides access to OpenLisp, an ISLISP implementation.

Copyleft Software AS

Small, Lisp-friendly Norwegian ISP. (Targeting the Norwegian market, really, so maybe this should be in some kind of local section?)

Lisp hosting at Zill.Net

Lisp-Friendly Web hosting company. Can run CLISP, CMUCL/SBCL for you. Primarily using OpenBSD/FreeBSD but can custom configure. "Standard" Lisp hosting at $24.95 per month, with ssh access to shared server - your lisp image runs behind Apache as a proxy. DNS service included.

http://common-lisp.net

This is not really Lisp Hosting but we are offering free CVS access, mailinglists and some web and ftp space. Restrictions apply, see within.

Bytemark Hosting

This is not really "Lisp Hosting" out of the box, either, but you do get a full Debian/Woody partition with 3GB and root access, for 15 GBP (approx. 24 USD) per month. Install CMUCL/clisp/your-favorite-implementation and go to town. You can also ask for other distributions and (for more money, of course) more disk and memory space.

Lycos VDS

Similar idea to Bytemark above. Starts at 7 GBP pm. Europe-wide, not just UK.

Phrase Purchase Hosting

Offers an SSH accessible account, with latest CLISP on GNU/Linux machines.

Slicehost

Xen VPS Slices - Built for Developers. Lisp friendly.

RootRoute Secure Hosting

Preinstalled Clisp and scsh as well as plenty other programming languages on OpenBSD servers. SSH access etc. Recent user experience says the virtual memory ulimit is far too low to run anything that manages its own heap, like SBCL or CMUCL. An ancient version of CLISP is installed by default.

Nearly Free Speech

Clisp installed and pay as you go. Extremely low cost if you're just trying things out. MIT Scheme, Guile, Chicken and MzScheme are installed for you lisp-1 fans. No persistent processes allowed, so you're limited to CGI.

Zettai

Don't really know anything about them. They include clisp by default and provide you with a virtual server (some BSD flavor). Seemed worth adding them to the list.

GrokThis.net

Clisp, CMUCL, and SBCL are installed and available for use by all clients. Advanced plans offer upto 100 megabytes of ram and a dedicated web server process. mod_lisp is available. Configuration of lisp based technologies NOT yet provided. Please contact sales for more information.

WebFaction

WebFaction is very popular in python world. They provide shared service, SVN and Trac which are easily configurable, and though they don't provide direct Lisp support, it's easy to setup your server under Apache / mod_rewrite using their sophisticated ControlPanel.

TekTonic

They offer VPS services that start at $15 a month. The VM is set up within a couple of minutes after the order. I've been running Hunchentoot on top of SBCL for two days and haven't encountered any problems. (another vote for Tektonic, been using them for years, very good XEN setup)

VPSLink

VPSLink offers full root-access and a bunch of Linux OS templates (debian, gentoo, fedora, slackware, opensuse, etc).

Dedicated Hosting Server

Cheap Lisp dedicated server by Webhosting.UK.com starting from £74 / Month. Free Management, free setup, dedicated network connection and more upgrade options available.

VPS Hosting Server

Micfo.com offers cheap Linux VPS hosting on the following Operating Systems (OS): CentOS 4.4, Debian 3.1, Fedora Core 5 and Gentoo. As your preferred control panel, you may choose from cPanel/WHM, Plesk and OpenVZ.

If none of these are suitable, you could just use any host offering CGI support, of course. There are far too many of them to list any such here; try a search engine.
