Planio, which is based on Redmine, relies in terms of communication on blog entries, discussion forums, comments. There's also team chat available in the pro version, but it's not as deeply connected to projects as in Stackfield.
Stackfield offers the same features, but additionally for each work area a team chat, through which messages can be exchanged fluently and in real time. In that communication stream, all changes from other modules are displayed, which you can directly comment - without opening a new window or page.
This is exactly where Stackfield differs from Planio: On Stackfield, you can directly comment on items or create a discussion based on a chat message. No complex processes are necessary - and if there's something you appreciate, you can simply click the like button.
Although Redmine / Planio offers a comprehensive system for task management, it's mainly developed for the Agile method. As a result, the kanban board can not be adapted to other processes, for example.
On Stackfield, you can choose between different view options for tasks, such as kanban or list view. You are also able to define parameters such as, for example, own statuses. As a result, Stackfield is not only suitable for the IT department, but can be used simultaneously in the marketing, sales and design team. For each department, you can define your own processes and workflows with just a few clicks.
The work on Stackfield takes place in rooms thata are located in an "organization", which can be either for the entire company or even a department. All employees are added to this organization and assigned directly to a rights group. If, for example, a person leaves the company, these settings can be used to remove this person from all work areas / rooms with one click. Likewise, within the work areas / projects, there is the possibility to create fine-grained authorization groups. This makes it clear at any time who has access to the data of the company!
Stackfield feels lighter and is easier to understand right from the start. All users of the tool benefit from that, both team members and administrators. This ease of use also allows different teams to use the tool together.
Moreover, on Stackfield, unlike Redmine or Planio, all relevant data are encrypted directly on the device of the user and securely stored on our servers in Germany. For more information about Stackfield security, please visit the following page: https://www.stackfield.com/security.
In addition, Stackfield does not require its own servers, maintenance, or installation when used in the cloud, making it a true Redmine alternative for small and large companies! (But there's also a self-hosted version available!)
