OpenPSA is a Web application designed specifically to meet the needs of Web agencies and consultants. It aims to be a one-stop solution for the management of typical agency business processes, such as project management and time tracking, invoicing and document management, and group calendars. It also includes CRM features such as sales force automation and direct marketing, and is extendable via the builtin component framework.
Ductus is a wiki system designed to handle arbitrarily-structured content and a variety of workflows. With Ductus, programmers can easily define classes of structured content, providing rich mechanisms for user interaction. For instance, the Wikiotics project uses Ductus to allow people to collaborate on "language lessons," which can later be used as quizzes or flashcards. Such modes of interaction are not possible with most wikis, which are designed primarily to handle freely-structured text.
Güickie is a fork of quickie, from Peter Miller, mainly because of the need to enhance the markup features. It is coded in C++, so it is lightweight and fast in comparison to most of the other wiki engines. In contrast, it is not as feature rich as the most known of them. But it uses ptdoc as an HTML formatting engine, and has a rich set of text formatting features.
PageWork is a wiki that focuses on fast content delivery as well as an expandable and adaptable code library. It explicitly separates the volatile run-time environment of a hosted site from the encapsulated code library, and has the ability to host multiple sites based on the same software. All pages and files undergo revision control of arbitrary depth. In combination with users and groups, access to resources is controlled by ACLs that resemble Unix permissions. Features include tagging, SEO, media and meta data management, comments, breadcrumbs, bookmarks, templates, memos, Atom/RSS feeds, adaptable resource caching, and site-wise and personal customization.
wadWiki is a extremely light and simple Wiki engine that anyone can modify. It aims to be a fast scratchpad for arranging ideas without frills and complications. Major releases are supported for more than three years, so server requirements don't get suddenly bumped. Since it is written using only procedural functions, anyone with basic programming skills can adapt it to new requirements. The extension API is stable. There is official hosting for third-party extensions. Because collecting knowledge is not the goal of this project, if you want a full-featured wiki engine, you may wish to choose another software like MediaWiki.
HiveMind Project Manager is a project management application featuring request tracking, and wiki-based content management. It supports multiple vendors, multiple clients, flexible billing rates, time recording, expenses, client and vendor/worker invoicing, payments, and general ledger. In addition to specific find screens for everything, there is a single screen with general text and parametric search across projects, tasks, requests, and wiki pages. Based on Moqui Framework and Mantle Business Artifacts, HiveMind has a solid business foundation and is well suited to complex customization.
