Web conferencing (only)

Comparison of Web Conferencing Products

I needed a simple web conferencing capability for sharing my computer screen with up to three other people over the internet.   The connection will frequently be over a low bandwidth connection, so I didn't want to rely on voice/audio with the conference as well, as that requires more bandwidth (cell phone with bluetooth headset is much easier / reliable).   Below is my exact criteria for the service:

  1. Desktop sharing with up to 3 attendees
  2. Minimum bandwidth requirements
  3. No download / plugin required for attendees to install
  4. Encrypted communications
  5. The screen viewed by the user should be of a good size, clear, and with good refresh/update relative to the source
  6. Super simple to use
Web Conferencing Applications
App Name Evaluation [1] Cost [2] Features [3] Comments
Join.me tried Free
(max 3 attendees, only host may share screen); LITE plan ($10/mo) allows participants to share scree.
Host sends url/link to attendees by email and they click on the link and are connected automatically, and the host's computer screen is shown (if shared).   Host must download and install browser add-in, but attendees to not need to install any plugin.   Secure.   Personalized URL.   Super easy for host and attendee to use.   Attendee and host controls are simple to use.   The view of the screen shared is fairly good (size can be adjusted), and it updates quickly relative to changes from the host.   My final choice
FreeScreenSharing.com tried Free
(max 1000 attendees); Individual plan at $6.95/mo allows attendee to share screen.
Browser plugin required for host, optional for attendee.   Oriented more to voice conferencing, but it does support screen share and video sharing, chat, etc.   Easy to use and the attendee can easily adjust the view so that the shared screen is as large as possible on their screen (worked better than Join.me).   What you get for free seemed too good to be true (but it wasn't).   This would have been my choice if I needed voice / teleconference capability.  
Mikogo none $192/yr for 1 host and 25 attendees No plugin required for attendees.   Mobile app option.   Voice and video conferencing   Session scheduling.   The website was well designed and easy to navigate.   The pricing should be changed so that it is free for 1 host & 1 attendee, and then the "standard" level is 1 host & 3 attendees.   The "Professional" package at $192/yr was required in order to achieve the goal of 1 host and at least 3 attendees.  
AnyDesk none $79/yr + $29 per additional attendee (seat) Encrypted to banking-standard TLS 1.2.   Windows, Mac OS, FreeBSD, iOS, Android, ..   Both host and attendee must download and install app.   Claims to work well on low bandwidth (100 kB/s).   Low latency and fast frame rates of 60 fps.   No admin privileges req'd for install.   The app is targeted at IT remote support and looks like a great app should I ever need remote control of a PC.   The requirement that a attendee (seat) was required to download and install an app failed my no dataplugin requirement, but it was still interesting to consider this product for screen sharing and occasional remote desktop control.  
AnyMeeting none $180/yr for up to 10 conference attendees see website.   Unable to determine if plugin is required for attendees.   Website poor.
