Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
voice-bridge
Give Claude Code a voice with multi-engine text-to-speech. Speaks responses aloud using 5 TTS engines (edge-tts, ElevenLabs, Kokoro, macOS say, espeak-ng). Free by default. edge-tts uses Microsoft Neural voices with no API key. Includes a Stop hook for automatic speech, a /speak skill for on-demand use, and an MCP server with speak, set_engine, get_status, and list_voices tools. Text is automatically filtered to remove code blocks, API keys, file paths, and markdown before speaking.
Uttera
Audio for your agent: transcribe, speak, translate, summarise, plus sound effects and music.
