Yet another font manager when Font Book and iOS already handle this.
Open-source font recognition avoiding proprietary databases like WhatTheFont requires.
afont wraps the Adobe Fonts API into a tidy agent skill and CLI: it supports local caching, API fallback, kit management, preview screenshot capture, and returns ready-to-use embed tags/CSS snippets. Nothing groundbreaking, but the packaging for Codex/Claude/OpenCode and the sensible cache/index commands make this an immediately practical tool if you already rely on agent workflows for build tasks.
Single-page font test with no depth beyond basic timing measurements.
Raycasting engine in 6.5KB of TrueType hinting bytecode—font VM as GPU.
Clean font previewer, but Google Fonts already covers most of these use cases.
