Tabula0.2.0

A database client you can point at production.

Browse, query and edit MySQL, PostgreSQL, SQL Server, SQLite and Redis in one window. Written in Rust, so it opens in under a second and installs in 10.6 MB. Then let an AI assistant help, with limits you set per connection and Tabula enforces.

Tabula showing a table list on the left, a query editor in the middle, and the assistant on the right walking through a database schema with the SQL it ran and the rows it returned.
The assistant answering a question about a live MySQL schema. It writes the SQL, runs it read-only, and shows you exactly what it ran.

Decide how far the assistant goes.

Every connection carries its own access level. Tabula classifies each statement and checks it in the Rust backend before the database ever sees it, so an agent cannot talk its way past the level you picked. Change the level below and watch what an agent is allowed to run.

orders-prod Access level Read

    A connection flagged read-only is capped at Read whatever the level says, and a production connection starts at Off. Anything above a read also needs the agent to ask for it explicitly.

    Tabula settings open on the AI agents panel, showing a saved connection with a permission dropdown set to Read, and a paste-ready setup command for Claude Code.
    Where you set it. The same panel gives you a paste-ready line for Claude Code, Claude Desktop, Codex or Cursor.

    Five engines, one window.

    Open several at once and switch between them on the left rail. Each keeps its own tables, query tabs and selection.

    Built for the work, not the demo.

    Edits you review before they land

    Inline edit, insert and delete collect into a changeset. Read the SQL, then commit. Optimistic concurrency catches a row that moved under you.

    Queries as files you can commit

    Saved queries are plain .sql files in a folder of your choosing, so the library lives in git next to the project it belongs to.

    -- name: monthly refunds

    Parameters bound as values

    Placeholders bind as typed values instead of being pasted into the text, so a date stays a date and nothing gets concatenated into your SQL.

    :start $1 ? @name

    Numbers that survive the trip

    Sorting compares DECIMAL and BIGINT exactly. Excel export keeps numbers as numbers and dates as dates, and long decimals stay exact.

    Read-only that means it

    A read-only connection is verified on the server before every statement, not filtered in the app, so a pooler or a reconnect cannot quietly reopen writes.

    Charts without leaving the grid

    Any result switches to a chart, with a picker for mark, axes and aggregate. Keep the chart beside the query and it reopens in chart view.

    Passwords in the OS store

    Credentials go to Windows Credential Manager, never into a config file and never into an exported connection.

    Fifteen themes

    Ten dark and five light, including Nord, Dracula, Tokyo Night, Gruvbox and Solarized. The title bar button flips between your last dark and light pick.

    The assistant runs on your machine.

    Ask about an error, a query plan, a result or selected rows, and insert the SQL it writes at your cursor. It runs through the Claude Code CLI you already have, on your own sign-in.

    Your sign-in, your quota

    Tabula starts the Claude Code CLI already installed on your machine. There is no Tabula account and no server in the middle.

    Credentials stay put

    Passwords and SSH secrets are read from Windows Credential Manager at connect time. They are never copied into a config file for an agent to read.

    Reads cannot write

    Every read the assistant makes runs inside a read-only transaction that is rolled back, under a time limit, so an exploratory query cannot leave a trace.

    Your other tools, same limits

    Tabula also runs as an MCP server, so Claude Code, Claude Desktop, Codex and Cursor can use the same connections under the same per-connection levels.

    Tabula settings open on the Assistant panel, showing a signed-in Claude Pro account, the detected Claude Code version and path, and a choice between the Opus and Sonnet models.
    It picks up the Claude Code you already have. Account details are blurred here.

    Pick one in Settings or from the command palette. The title bar button flips between the last dark and light theme you used.

    Check the file before you run it

    Compare the hash of what you downloaded against the one listed above. If the two do not match, delete the file and download it again.

    Windows will warn you once

    Tabula has no code-signing certificate yet, so SmartScreen says it protected your PC. Choose More info, then Run anyway. That is also why the hashes above are worth checking.

    Credential Manager asks the first time

    The first time Tabula saves or reads a connection password, Windows asks for permission to use its secure store. Approve it. It can ask again after an update.
