Free and open-source no-code database tools are not interchangeable: some offer a hosted free plan, some can be self-hosted, and some are designed to put a spreadsheet-style interface over an existing SQL database. The evidence available supports a careful shortlist—not a verified ranking of nine tools or a complete comparison of their current free-plan limits.

Free and open source mean different things

A free cloud plan lets you use a hosted service without paying while you stay within its plan limits. Open-source software makes source code available under a license that grants specified rights; running it yourself may still require a server, setup, maintenance, backups, and security work.

Those distinctions matter when choosing a no-code database. A product may be open source while reserving some features for paid plans, or offer a free hosted tier without being open source. Check the license for the specific edition and the current feature matrix rather than treating “free” as a promise of unlimited use.

Tools to investigate

Baserow: a practical starting point

Baserow presents itself as a no-code platform for databases and application building, with cloud and self-hosted deployment options. Its repository says that non-premium and non-enterprise features are licensed under MIT; this does not mean every feature is free. The repository showed version 2.4.0 when reviewed, and versions and plan details can change. See the Baserow GitHub repository and its official pricing page for the license and current plan-dependent feature information.

The pricing page lists capabilities such as grid, form, and gallery views, collaboration, imports and exports, automations, application building, and integrations, with availability varying by plan. Baserow is a reasonable candidate if you want an Airtable-like database experience and want to consider either hosted or self-managed deployment. That is a fit based on its published positioning, not a hands-on product test.

NocoDB: investigate it for existing SQL tables

A secondary comparison describes NocoDB as a spreadsheet-style interface for existing databases. That distinction may make it worth investigating if you already have SQL tables and want a more approachable way to work with them. The current license, supported database engines, free-plan terms, and exact feature set are not established here; verify them in NocoDB’s official documentation before choosing it.

Teable and Grist: further self-hosting candidates

A secondary comparison identifies Teable and Grist among self-hosted alternatives, describing Teable as Postgres-oriented and API-first, and Grist as a formula-oriented spreadsheet. Treat these as candidates to check, not verified evaluations: confirm the current licensing, deployment requirements, and features in each project’s official documentation before relying on those descriptions.

SeaTable and Airtable: adjacent options, not equivalent open-source entries

A 2026 secondary comparison includes SeaTable and Airtable as adjacent choices. SeaTable may merit consideration if you are comparing hosted and self-hosted spreadsheet databases, but its current licensing and plan details are not verified here. Airtable is a proprietary benchmark, not an open-source option. Check each vendor’s official information before using either in a procurement decision.

How to choose for your use case

  • Decide whether you need a hosted plan or self-hosting. Hosted service reduces infrastructure work but is subject to its plan limits. Self-hosting can offer deployment control, but you take on operations such as updates, backups, and security.
  • Check what the license covers. Review the license for the edition and features you intend to use. In Baserow’s case, its repository specifically distinguishes non-premium and non-enterprise features from premium and enterprise features.
  • Clarify where the data model lives. Determine whether the tool creates and manages its own database or provides an interface to existing SQL tables. NocoDB is described by a secondary source in the latter role; confirm that fit and supported engines with official documentation.
  • Test the workflows you actually need. Check views, forms, formulas, APIs, automations, permissions, and collaboration. Do not assume a capability listed for a product is included in its free plan.
  • Check current limits before migrating. Confirm free-tier limits, export options, and whether important controls are plan-gated on the vendor’s current pages. Avoid relying on old plan comparisons.

What this comparison can and cannot establish

The available sources support Baserow as a defensible starting candidate and identify NocoDB, Teable, and Grist as alternatives to investigate. They do not establish a reliable nine-tool ranking, current free-tier limits for all candidates, or a fully verified comparison of licenses and features. A trustworthy nine-way shortlist requires checking each product’s official documentation, repository or license, and current plan details. No exact plan prices or row limits are provided here.
