Open Source Smartsheet Alternatives

Baserow lets teams organize data, build internal applications, and automate workflows without writing code. It works as a structured database with multiple view types (grid, kanban, calendar, timeline, form, and survey), so different teams can work with the same data in whatever way suits them.

On top of the database layer, you can build full applications using a visual page and dashboard composer. These apps sit directly on your data, so there's no need to export or sync between tools.

Automation is built in. You can create workflows with triggers, branches, conditions, and loops, and connect them to HTTP requests, email, webhooks, or third-party services. An audit log keeps a record of actions for compliance purposes.

Baserow is a popular Airtable alternative. It covers similar ground but adds self-hosting, an MIT open-source license, frontend and backend plugin support, and compliance certifications for GDPR, HIPAA, and SOC 2 Type II. Row limits and API restrictions that frustrate Airtable users at scale are not a factor when self-hosting.

An AI assistant called Kuma can generate database structures from a plain-language description, which speeds up initial setup. AI fields and agent support are also available for adding AI steps inside workflows.

Teams that want NocoDB- or Teable-style open-source flexibility but need a more complete app-building layer will find Baserow covers more ground. It's a practical fit when you need to keep data on your own infrastructure, avoid per-user pricing at scale, or meet stricter data governance requirements.

Plane is an open source project management platform that combines issue tracking, documentation, and AI-powered workflows into a single workspace. It's built for software teams that want the flexibility of self-hosting without giving up the polish of tools like Jira or Linear. Projects, wikis, cycles, and dashboards all live in one place, and the AI layer is woven throughout rather than bolted on afterward.

The AI side is genuinely central to how Plane works. Plane AI reads across your entire workspace, including projects, cycles, docs, and threads, so you can ask it about blockers, cycle status, or recent doc changes and get answers grounded in your actual data. Built-in agents can triage incoming requests, assign owners, and post updates automatically. There's also a Slack integration that lets you describe work in a channel and have Plane create, assign, and track it without switching tools.

For teams managing work across different roles, Plane offers board, spreadsheet, list, and Gantt views. Cycles handle time-boxed sprints with burndown charts and velocity tracking built in. Initiatives and epics let you roll team-level work up to org-level goals. Dashboards populate automatically from live data, so there's no manual reporting.

Self-hosting is a first-class option. Plane supports Docker and Kubernetes deployments and includes a God Mode admin panel for configuring SSO, SAML, LDAP, SMTP, and workspace security. Air-gapped environments are explicitly supported, which is rare among modern project management tools. If you're comparing open source alternatives, that air-gap support is a meaningful differentiator.

For teams migrating from Jira, ClickUp, Asana, or Monday, Plane offers full data migration including issues, attachments, comments, and automations. The open API, webhooks, OAuth apps, and a native MCP server make it extensible for teams that want to build custom integrations or AI agents on top of the platform. Projects-as-Code via YAML definitions lets engineering-oriented teams version and deploy project configuration from Git.

OpenProject is a project management suite built for teams that want full control over their data. It supports classic, agile, and hybrid approaches in a single platform, so you're not forced into one methodology. Organizations with strict data requirements, including government agencies, universities, and NGOs, make up a large share of its user base.

The core feature set covers a lot of ground:

• Gantt charts for visual project planning and scheduling, with dependencies and milestones
• Agile boards supporting Scrum and Kanban workflows, with backlog management and sprint planning
• Team Planner for assigning tasks across a weekly or bi-weekly calendar view
• Time and cost tracking with reporting built in
• Work packages as the central unit for tasks, bugs, features, and more, each with custom fields, watchers, and history
• Meeting management and wiki-style documentation inside each project

Data sovereignty is a genuine differentiator here. You can install it on your own infrastructure and keep everything behind your firewall. The Enterprise on-premises edition adds security features like two-factor authentication, LDAP group sync, and custom branding. For teams that don't want to manage servers, an EU-hosted cloud option is available.

OpenProject is licensed under GNU GPL v3, and development happens publicly. The free Community edition is fully functional and has no time limit. It's a credible Jira alternative for teams leaving Atlassian's self-hosted products, with a migration tool specifically for that transition.

Compared to lighter tools like Kaneo or Operately, OpenProject is heavier and more structured. That's the point. It's built for organizations running multiple concurrent projects that need audit trails, role-based permissions, and reporting across portfolios.
