Web based – Once you have activeCollab installed on your server only thing you’ll need to use it is web browser. Most of the modern browsers are supported (Internet Explore 6, Mozilla Firefox etc).

• You can use activeCollab free of charge.
• You can redistribute it without any limitations.
• You can make modifications and while they are used in-house they can stay closed. If you start distribution of modified system you need to make modification publicly available under the terms of General or Honest Public License.
• You can’t charge for the software itself even if it is modified.

The whole point is about sharing, not just using.

No limitations – Some systems are limited by the number of users, clients or projects that you can have at the same time. activeCollab comes without such limitations. You can have as many projects (client companies, users, task lists or anything else) as you need.

Per project permissions – You can have two types of projects:

1. internal projects where only your company is involved in development
2. project where you have one or many client companies involved

In both cases there is permissions system that enables administrators to set up access permissions to specific companies and users, even for the members of your own team. You want Peter to have access to Project A and Project B but you don’t want him around Project C. Not a problem.

You can also limit access permissions for specific tools in a project. So, you can give access to messaging part of the project to some of your clients, but restrict file upload and task management.

Private data – Some objects have option to be marked as private. In that case only members of owner company that have access to specific project will see it and be able to manage it. Clients will not be aware of existence of that objects (message, milestone, task list…)

Private data remains private among members of owner company.
