undb is an open-source no-code database and backend-as-a-service platform built around SQLite.
What undb is
undb is an open-source no-code database and backend-as-a-service platform built around SQLite. It provides table management, formula fields, and OpenAPI REST support, with published OpenAPI documentation. A browser playground lets users explore the platform without registration or installation, but its data remains only in browser memory and disappears when the page is refreshed or closed. Deployments can run with Docker or be built from source. Documentation lists SQLite, Turso, and PostgreSQL as database providers, along with GitHub and Google OAuth configuration. Storage options include local storage, MinIO, and Amazon S3, while email can use SMTP through Nodemailer or Mailgun. The terms describe free and paid services, with possible storage and OpenAPI request-frequency limits on paid services. The privacy policy states that data is encrypted in transit with HTTPS. The GitHub repository was archived on September 22, 2026, and says development moved to Teable, making that project status central for new deployments.
Good
- Open-source and free
- Browser playground needs no registration or installation
- Supports Docker and source builds
- Offers OpenAPI REST support
- Lists SQLite, Turso, and PostgreSQL providers
Watch out
- GitHub repository was archived
- Playground data disappears after refresh or closing
- Paid services may limit storage and API frequency
Who it suits
undb suits developers seeking an open-source, no-code database platform with self-hosting, API, and configurable storage or authentication options. The archived repository matters to anyone considering it for a new deployment.
Verdict
undb offers a broad self-hosted and API-oriented feature set, including database, storage, authentication, and email integrations. However, its repository is archived and points to Teable, so adopters should account for that transition.
