ExphoraDB

A fast, lightweight dataset viewer and explorer for your desktop. Open your data, filter it, analyze it, share it — no cloud required.

Tech Stack

Rust backend, React frontend, no nonsense.

• Core & Backend — Tauri v2 + Rust
• Frontend — React 19 + TypeScript
• State — Zustand
• Styles — Tailwind CSS v4
• Charts — Recharts
• Icons — Lucide React

---

Supported Formats

Open, explore and export all of these:

Format	Extensions
Exphora Views	.exh
JSON	.json
JSON Lines / NDJSON	.jsonl, .ndjson
CSV	.csv
XML	.xml
SQLite	.db, .sqlite, .sqlite3

Export to: CSV, JSON, Excel, Markdown, PDF.

(Pro tip: the .exh format acts as a complete saved workspace for your session, seamlessly preserving active filters, column configurations, chart states, and dataset paths. It also features floating markdown notes per view, column annotations, Smart Save, and native OS file associations.)

Architecture

Two clear layers, nothing weird.

src/ — Rust backend Native OS integration via Tauri. Handles file I/O, schema inference (parser.rs), filtering and stats (filters.rs), expression eval (expr.rs) and the full P2P layer (p2p/).

ui/src/ — React frontend Modular SPA split into:

• components/ — virtualized tables, sidebars, modals, overlays, charts
• hooks/ — useDataset, useFilters, useFocusTrap, useAutoSave and more
• store/ — global tab state via Zustand (appStore.ts)
