sqlite-panel

A plug-and-play SQLite admin panel for FastAPI — beautiful, fast, and intelligent by default.

Features

• One-line mount — works with any FastAPI app
• Auto-discovery — detects all tables and columns automatically
• Smart cell rendering — JSON formatting, inline image previews, boolean badges, long text expand/collapse, file & URL links
• Pagination, sorting, filtering, search — all built-in
• Inline editing — double-click any cell to edit in place
• Real-time change detection — toast notifications + auto-refresh when the DB changes
• Read-only mode — disable all writes with a single flag
• Light & dark mode — with smooth toggle and localStorage persistence
• Keyboard shortcuts — / to search, n for new row, Esc to close modals
• SQL injection safe — all user input is parameterised or strictly validated
• Zero heavy dependencies — HTMX for partial refreshes, vanilla JS, Geist font via Google Fonts

├── db.py              # Core DB logic (pure Python, no web deps)

Key design decisions:

• db.py has zero FastAPI/web imports — testable in isolation
• renderers.py has zero DB imports — pure value → HTML transformation
• All SQL uses parameterised queries or _safe_identifier() validation
• HTMX partial endpoints allow row refresh without full page reload
• Change detection via polling /api/fingerprint (row count hash)
