The following companies support the ASCOM initiative, and either have products or drivers available which are ASCOM compatible or have embraced the ASCOM requirements. This list encompasses drivers, clients which use drivers, as well as programs that offer proprietary scripting capabilities. Note that the ASCOM requirements prohibit vendors from explicitly using the name ASCOM in conjunction with experimental, beta, or other unsupported products, so you may not see ASCOM explicitly mentioned for their products. Products are listed in alphabetic order by product name.
Note: In the table, a "client" is a program which uses the services of one or more ASCOM component object servers. "A "server" is a program or component that provides scriptable objects to clients. A program marked "both" uses objects from one or more other ASCOM servers, and also provides scriptable objects of its own for use by other clients. An 'adapter" is a component that converts a proprietary interface to an ASCOm standard interface, allowing compatibility with ASCOM-compliant programs.
