Lombiq maintains and/or provides commercial support for multiple open source projects, Orchard modules and themes, as you can see under our GitHub profile. There are two projects that we actually published along with the founding of Lombiq: Pretty Good Bootstrap Base Theme and Orchard Read-only.
PGBBT is an Orchard theme that is intended to be used as a base theme. It contains Twitter's Bootstrap CSS framework and adapts it to be used with Orchard. Styles are packaged as individual files so you can use only what you really need. The theme employs a minimal amount of shape template overrides for maintainability and LESS for helping re-usability. PGBBT is the base theme under the themes of Orchard Dojo and Lombiq.com itself.
Read-only is a simple module for a simple task: to switch your Orchard site into "read-only mode". That means, with this module you can put your site into a state where no content item can be saved. Instead, a customizable message is displayed. This is useful if you want to freeze your site's content for a short time for some reason - we use it for seamlessly updating our sites' code (more on that later).
We hope you find our open source project useful!
