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.
