Ogma — Fate Condensed GM Aid

A browser-based, offline-first progressive web app for Fate Condensed GMs. Generate world-specific content, run sessions, track players — all in one tab.

Live: ogma.net

Features

• 17 generators × 8 campaign worlds (136 generator/world combinations)
• Freeform canvas — generate cards, arrange, connect, annotate (native pan/zoom)
• Session Zero — guided world/character setup → export to prep canvas
• Offline-first PWA — works without internet after first load
• Multiplayer — players join via room code, see GM canvas in real time
• Export — Markdown, JSON, Excalidraw

Stack

• SvelteKit + Svelte 5 (runes: $state, $derived, $props)

• bits-ui — accessible headless UI components
• Font Awesome 7.2 Free — icons (cached by SW for offline)
• Dexie 4 — IndexedDB persistence
• Vite 7 + adapter-static — build
• Cloudflare Pages — deploy

Architecture

See CLAUDE.md for architecture rules, component inventory, and engineering conventions. See docs/claude/ for session bootstrap, project memory, team voices, and world voices.

Key rules

1. All styling in static/assets/css/theme.css — no <style> blocks
2. engine.js and db.js are pure JS — no Svelte imports
3. Svelte 5 runes everywhere — $state(), $derived(), $props()
4. Canvas cards must not have left/top on the component — only the .cv-card-positioner wrapper

Worlds

Shattered Kingdoms (fantasy) · Neon Abyss (cyberpunk) · Void Runners (space) · The Long After (post-apoc) · The Long Road (road post-apoc) · Gaslight Chronicles (Victorian) · Dust and Iron (western) · dVenti Realm (original fantasy)

History

Built March 2026. Original React 18 CDN UMD codebase migrated to SvelteKit + Svelte 5. SvelteFlow canvas replaced with native pointer/wheel canvas in v662. The react-source/ directory contains the original codebase (read-only reference).
