Open source alternatives to SmartSuite

By GitHub stars it is OpenProject, with 17,349 stars and a commit on 13 Nov. Choose OpenProject when you need portfolios, budgets, time and cost reports in one tool that you can host on-premises. Next come Leantime (12,099 stars) and Worklenz (3,307 stars).

Yes. The code of all 3 is public under GPL 3.0 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 SmartSuite for. Choose Leantime when you want tasks tied to goals, Lean canvases and retrospectives without paying per seat on the self-hosted edition. Choose Worklenz when you need ready-made project finance and client portal features rather than building your own work apps.

All 3: OpenProject, Leantime and Worklenz. Each tool's page says what it needs to run.

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

AGPL 3.0 (2), GPL 3.0 (1). 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. SmartSuite'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.
