Open source alternatives to ScrumDesk

By GitHub stars it is WeKan, with 21,171 stars and a commit on 13 Nov. Choose WeKan when you want backlogs, sprints, burndown charts and swimlanes in an MIT-licensed tool that needs no database server. Next come Taiga (857 stars) and Windshift (428 stars).

Yes. The code of all 3 is public under MIT, MPL 2.0 or AGPL 3.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

Start from the job you use ScrumDesk for. Choose Taiga when you want Scrum and Kanban boards for any number of users on your own server, with no licence fee. Choose Windshift when you want sprints, backlogs and boards for any number of users free, where ScrumDesk charges from the fifth user.

All 3: WeKan, Taiga and Windshift. Each tool's page says what it needs to run.

All 3 we track had a commit in the last 30 days, among them WeKan, Taiga and Windshift. A recent commit shows the project is kept up, not that it will stay that way.

MIT (1), MPL 2.0 (1), AGPL 3.0 (1). MIT, BSD and Apache let you change and reuse the code freely. GPL and AGPL ask you to share your changes under the same licence when you give the software to others, and AGPL also counts letting people use it over a network.

The hosting. ScrumDesk's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
