Open-source alternatives to Smartsheet

Smartsheet is a SaaS work management platform that layers Gantt charts, Kanban boards, dashboards, and automation on top of a spreadsheet-like grid. It's closed source and priced per user, with advanced automation and reporting features gated behind higher tiers.

Baserow and NocoDB take a database-first approach instead — closer to Airtable than to project-management software — so they fit best if what you actually need is a flexible, structured data store with a spreadsheet UI rather than Smartsheet's Gantt/PM-specific views. NocoDB is the stronger choice if you're layering this on top of a database you already run.

FAQ

Is there a free, open-source alternative to Smartsheet?

Yes. Baserow and NocoDB are both open source and free to self-host.

What's the best open-source alternative to Smartsheet?

Neither is a direct feature-for-feature clone of Smartsheet's Gantt/PM tooling, but NocoDB is the better pick if you want to expose an existing database as a spreadsheet, while Baserow is better for building new structured-data apps.
