Catalyst DBench

The universal database IDE, built in Rust.

DBench is a fast, open-source, cross-platform desktop application for connecting to, querying, and administering any database — from a single unified interface.

---

Why Catalyst DBench?

Modern stacks are polyglot. You use Postgres in production, Redis for caching, MongoDB for documents, DynamoDB on AWS. Every database ships with its own GUI tool — each with a different UX, different install process, different shortcut keys.

DBench gives you one IDE for all of them.

• Zero config switching between databases
• Consistent UI and keyboard shortcuts across every DB type
• Native performance — built in Rust, powered by Tauri
• Fully open source, forever free for individuals

Features

• Query Editor — Monaco-based editor with SQL/NoSQL syntax highlighting, auto-complete, snippet bar, and formatting
• Schema Explorer — Browse tables, collections, indexes, and relationships; MongoDB grouped by database (Atlas-style)
• Data Grid — High-performance table with sorting, filtering, pagination, inline editing, and delete for both SQL and NoSQL

• Multiple Tabs — Work across multiple connections simultaneously; tabs show table/collection name
• App Menu Bar — File / View / Tools dropdown menus (MongoDB Compass-style)

• Query History — Full history of executed queries including inline edits
• Export — Export results to CSV or JSON; export schema as SQL DDL
• Import SQL — Open .sql files directly into the query editor
• MongoDB Support — JSON query mode (find, aggregate, update, delete, insert), Atlas-style tree, explain plans
• ClickHouse Support — HTTP API driver with full schema introspection
• Dark / Light theme — Toggle from menu or keyboard shortcut
• Zoom — Ctrl+= / Ctrl+- zoom in/out without breaking editor cursor placement

Architecture

DBench is a Tauri v2 desktop application with:

• Rust backend: All database logic, connection pooling, query execution, schema inspection
• React frontend: UI built with React 19, Monaco Editor, and TanStack Table
• Trait-based driver system: Adding support for a new database means implementing two Rust traits

dbench-core        — Core traits (Driver, Connection) and types
dbench-macros      — Derive macros for driver boilerplate
dbench-drivers     — Database driver implementations
dbench-engine      — Query execution, connection pooling, schema inspection
dbench-app         — Tauri application backend (IPC commands)
frontend/            — React + TypeScript UI

See PLAN.md for the full architecture and roadmap.

Contributing

Contributions are very welcome! DBench is an ambitious open-source project and there is a lot to build.

See CONTRIBUTING.md for how to get started. Good first issues are labeled good first issue.
