Packages

Headless pptx deck writer/reader — markdown headings, highlighted code, tables, gradients, and a high-fidelity reader.

Shared pure core for the Fancy document/surface packages — the model an agent or human emits and edits. Flat node-tree + collab-safe fractional ordering, a typed op-spine contract (reduce + invert), an infinite-canvas primitive, and a surface-agnostic staged-write (accept/reject) model. Zero dependencies, no React.

Shared pure core for the file-focused packages (editors / viewers / writers / diff surfaces) — the structured diff engine + model, git unified-diff parser, merge resolution, per-line gutter annotations, path helpers, and filename→language. Zero deps, no React; fancy-diff re-exports it and the fancy-code diff gutter runs on it.

Headless xlsx spreadsheet writer/reader with a formula engine — one Agent write / describe / lint API, mirrored across languages.

Headless docx writer/reader on one JSON Doc model — headings, styled runs, lists, tables, code — with markdown bridges both ways.

Multi-level referral / network-marketing engine — configurable unilevel / binary / matrix downlines from one CompensationPlan JSON, with identical rewards across languages and a React surface for trees and statements.

Headless Stripe catalog — products / prices / plans + checkout — adapter-based with an injected Stripe client.

Headless feature management — gate / registry / config / group strategies plus metered quotas. Owns the FeatureSource contract catalog plugs into.

Analytics-driven gamification — XP, achievements, prizes, and leaderboards. Powers the sandbox's engagement economy.

End-user (not search-engine) optimization — human + agent interaction analytics: event ingestion, focus heatmaps, and session / actor rollups, with a browser collector.

Installable + offline PWA layer — manifest, lean service worker, install/offline/update hooks, and a fancyPwa() Vite plugin. Framework-agnostic, SSR-safe.

Server-rendered SEO + crawlability for Laravel + Inertia — per-route meta / Open Graph / Twitter / JSON-LD on the first byte, dynamic sitemap.xml / robots.txt / llms.txt, and per-page Markdown. The PHP baseline that pairs with @particle-academy/fancy-inertia's <Seo>.

Well-known + agent-facing files from one declarative registry — robots.txt, security.txt, humans, llms, sitemap, AGENTS — with a leak-safe protect() guard, plus an admin UI to edit them.

MCP docs server — serves the Fancy UI documentation to agents over MCP, so an assistant can answer questions and pull usage straight from the source.

Shared Human+ primitives — AgentActivity events, presence, undo stacks, and effect helpers. Low-level plumbing reused across the kit; usually installed transitively.

CDN-safe browser relay channel for agent-integrations' RelayTransport. Adaptive SSE↔long-poll with Cloudflare detection, so the MCP relay survives a Cloudflare/HTTP-3 edge that resets long-lived SSE streams. Zero runtime deps.

Source-vendoring CLI — `npx fancy-cli@latest add <component>` copies component source from the registry into your project (the shadcn-style own-the-source path).

Git as a first-class, agent-driveable surface — a headless engine with proposal-first mutations, normalized provider adapters for GitHub / GitLab / Bitbucket, and a React UI. Mirrored in PHP and Node.

Super-lite, single-file MCP client (bash / Python / TS / Go) for connecting an agent to a session-based relay — drive any agent-integrations-hosted app (e.g. the Agent Playground) from your terminal. Download one file, or run the zero-install npx CLI; point it at a session URL.
