Code health
This codebase scores 6.9 out of 10 for code health, which we rate fair. It also scores maintainability 8.2 and static performance 9.7 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 76 of 868 files are git hotspots, and they average 3.8 — which is where the fixes pay off most.

How tabularisdb/tabularis works
tabularis uses a TypeScript application in src for the desktop interface and database workspace features. The src/pages/Editor.tsx file provides the SQL editor, while src/components/ui/DataGrid.tsx displays tabular query results. The src-tauri directory provides the Rust Tauri layer, including commands in src-tauri/src/commands.rs and database driver code such as src-tauri/src/drivers/mysql/mod.rs. The packages/plugin-api module exposes the plugin API, and packages/create-plugin provides plugin creation scripts and templates. The application connects to databases, executes SQL, and presents results in editor tabs, notebooks, grids and visual plans.
Open-source desktop SQL workspace for PostgreSQL, MySQL/MariaDB, SQLite and 13+ more databases like DuckDB, ClickHouse, Redis and Firestore. Built-in MCP server for Claude, Cursor and Devin, SQL notebooks and visual EXPLAIN. This page is a map of the tabularisdb/tabularis repository, written primarily in TypeScript, rebuilt from the source each time it is indexed. Repowise parses every symbol, computes a dependency graph, scores per-file code health from complexity, duplication, test coverage and churn, mines git history for hotspots and ownership, and lifts the architectural decisions into documentation you can read here or query through MCP.
The codebase has 868 files and 6,172 symbols in 7 modules, led by TypeScript, Rust and JavaScript. Code health is 6.9 out of 10, rated fair.
