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
join-meeting
AgentCall turns any AI coding agent into a meeting participant. Install the `join-meeting` command, give your agent a meeting link, and the agent joins the call as a bot with a name and visual presence — it can talk, listen, screenshare, chat, and keep working on your codebase while in the meeting. Works with Claude Code, Cursor, Codex, Gemini CLI, Windsurf, OpenClaw, Junie, and 30+ other agent frameworks. Modes: - Audio-only — voice presence for standups and 1-on-1s - Webpage-avatar — voice + animated visual presence - Webpage-avatar-with-screenshare — full presence for presentations and demos What's included: real-time transcription (English, more languages coming soon), interruption handling, 54 TTS voices across 9 languages, collaborative mode with GetSun voice intelligence for natural multi-party conversations, direct mode with Kokoro TTS for latency-sensitive 1-on-1 interactions. API key required (free sign-up, no credit card): https://app.agentcall.dev
