Convert an HTML site into Composr pages

LDAP support for corporate networks (Conversr only)

HTTP authentication: Tie into an existing HTTP authentication-based login system (Conversr only)

Proxying system: Programmers can integrate any existing scripts using our sophisticated proxying system (which includes full cookie support).

Minimodules and miniblocks: Programmers can port existing PHP code into Composr itself without having to strictly conform it to Composr's framework

Intuitive sitemap editor: Visually browse your site structure.

Menu editor: Our user friendly editor can work with several different kinds of menu design (drop-downs, tree menus, pop-ups, etc)

Zones (sub-sites): Organise your pages into separate zones. Zones can have different menus, themes, permissions, and content. They can also use a sub-domain.

Full structural control: Edit, move, and delete existing pages and modules.

Redirects: Set up redirects if you move pages, or if you want pages to appear in more than one zone.

Use Composr for clients and pretend you made it.

We ensure Composr is not hard-coded anywhere in the software where it would appear to an average user.

As of July 22, 2024, we entered beta status where our focus is now smashing bugs and stabilising the software. All planned features have been implemented for 11.0 (and most others deferred to 11.1 or later), though we may still merge in a few minor features or tweaks. The upgrader has been tested on a typical non-custom v10 site.

We will be releasing several beta versions in the beta phase.

We do not know when we will be able to release the first Release Candidate or stable versions at this time.

These plans are all subject to change without notice.
