Tabellum DBMS

Tabellum is a database client for people who look after real databases. Connect to PostgreSQL, MySQL and MariaDB, SQL Server, BigQuery, SQLite, and MongoDB, browse the schema, page through tables, and run queries — from your iPhone or iPad, directly or through a tunnel. A demo database is built in, so you can try everything before you connect your own. BROWSE AND EDIT • Tables, views, functions, sequences, and enum types in one tree, with columns, keys, indexes, and constraints in the inspector • A fast results grid: paging, filters, sorting, a JSON view, and copy as CSV, JSON, or SQL • Edit cells in place; every change becomes SQL you review before it runs, in a transaction where the database has one • Run several statements at once, each result in its own tab, and read a query's plan as a tree • MongoDB collections as documents, with find and aggregate commands • Users and roles, views with conditions, and table functions with arguments SEE AND DESIGN • Charts from any result, and dashboards that read from several databases at once • Schema diagrams with their foreign keys • A schema designer: draw tables, columns, and keys, review the change as SQL, and apply it in one transaction • Compare two schemas, or a schema with a saved snapshot, and get the migration between them AN AI ASSISTANT THAT ASKS FIRST • Ask in plain language; the assistant explores the schema, writes the query, and shows the result as a table with its SQL • Bring your own OpenAI, Anthropic, or Google Gemini key — requests go straight from your device to the provider you choose • Every write, schema change, or admin statement stops at an approval screen with the exact SQL and the rows it would touch • Row values reach the model only for connections where you allow it; by default it sees the structure, not your data SAFE BY DESIGN • Each statement is classified by a real SQL parser before it runs — read, write, schema change, or admin • Read-only connections are enforced by the database server as well • Passwords, tunnel keys, and API keys stay in the iOS Keychain • No account, no analytics, no ads, no tracking REACH ANY SERVER • SSH tunnels with keys or passwords, and WireGuard tunnels built into the app — no system VPN, no extra app • TLS to the database, and servers on your local network YOUR FILES • Connections, saved queries, dashboards, and designs are plain YAML and SQL files in the app's folder • Keep them in a GitHub, GitLab, or Bitbucket repository and sync them between your devices • Export tables and schemas as SQL, CSV, JSON, or Excel, and import SQL, CSV, and JSON back The user guide, with every screen marked up, is inside the app and needs no network. Tabellum works on iPhone and iPad, with a layout that uses the space a tablet gives it.
