Are there any screen sharing apps that handle large participant meetings with recording and stable low-latency playback?

Yes. If you need large meetings, screen sharing, recording, and stable low-latency playback, the best options are usually the mainstream conferencing platforms rather than pure screen-sharing tools.

Good options

• Zoom
  • Strong for large meetings
  • Reliable screen sharing
  • Local/cloud recording
  • Generally good latency and playback quality
• Microsoft Teams
  • Good for large organizations
  • Screen sharing and recording built in
  • Stable, especially in enterprise environments
• Google Meet
  • Easy to use and scalable
  • Built-in recording on paid plans
  • Usually solid performance, though fewer advanced controls than Zoom
• Webex
  • Very strong for enterprise-scale meetings
  • Recording, low-latency streaming, good stability
  • Often preferred for larger formal events

If “low-latency playback” matters most

If you mean the audience should experience near-real-time video with minimal delay, look for:

• Zoom Webinar / Zoom Meetings
• Webex Events / Webex Meetings
• Microsoft Teams live events / town halls
• Dedicated webinar platforms like Hopin, Demio, or BigMarker for presentation-heavy events

If you want actual “screen sharing app” behavior

For simple screen sharing with recording, tools like:

• Discord
• Slack huddles
• AnyDesk/TeamViewer can work, but they are not ideal for large meetings or reliable recording/playback.

Best practical recommendation

• For general large meetings: Zoom
• For enterprise environments: Webex or Teams
• For easy browser-based meetings: Google Meet
• For webinar-style broadcasts: Zoom Webinar or Webex Events
