Tabellum: SQL Database Client

@dudko.dev

About this app

Tabellum is a database client for people who look after real databases. Connect to PostgreSQL, MySQL and MariaDB, SQL Server, and BigQuery, browse the schema, page through tables, and run SQL — from your phone or tablet, directly or through a tunnel.

BROWSE AND EDIT
• Tables, views, functions, and sequences in one tree, with columns, keys, indexes, and constraints in the inspector
• A fast results grid: paging, filters, sorting, JSON view, 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
• Users and roles, views with conditions, and table functions with arguments

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 Android Keystore
• 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 VPN permission, no extra app
• TLS to the database, and servers on your local network

YOUR FILES
• Connections and saved queries are plain YAML and SQL files in the app's folder
• Export tables and schemas as SQL, CSV, or JSON, and import them back

What’s new

• Saved queries go into the queries folder, subfolders too; rename or delete one from its menu
• Dashboards named in Cyrillic get files of their own; a renamed dashboard no longer leaves a copy
• Add to dashboard takes the statement that ran
• The AI assistant can save, rename and delete queries and delete dashboards — each change waits for your OK
• Run takes the selection or the statement at the cursor; several statements get a result tab each
• Copy error on every connection error
