Faster file transfer

Slow file transfer has long time been an issue for plugins exchanging binary data. But recently we partnered with a gaming company that will produce mini-games for and decided to take a fresh look at the transfer problem. And, here it goes: we managed to speed the transfer up almost 4 times!

By the way, we have started a public Trello board where you all can vote for proposed features and suggest new ones:

Plugins update

  1. We've posted recently that we had a few updates to our white board plugin called "Sketcher". So now it's finalized. Feel free to try out all new features: tabs, new drawing tools, undo/redo, saving, hot keys.
  2. Room manager (breakout rooms) — drag and drop users between new rooms before sending invites.
  3. Voting/polling plugin using Google Forms.
  4. Calendly plugin — find the perfect meeting time with this appointment scheduling software.

Social media streaming is here 🕺

We have just launched our second big thing of the year — streaming using RTMP protocol. Now you can stream your confererence calls and webinars directly to Facebook, YouTube and other platforms supporting live streaming.

This feature is currently in public beta and you all are welcome to test it for free. Don't get disappointed that there are so few features, our primary goal is to assure it is all stable when lots of users come onboard.

Here's how you can participate in testing:

  1. Add Streaming plugin in our plugins manager. Don't worry, it's very light, just some minimal UI.
  2. Send a mail to specifying your email address you signed up with.
  3. Get a confirmation from us and then connect your streamer in the back office, "webhooks & robots" tab.
  4. As soon as you enter the room you connected the streamer to you'll see a green indicator on the plugin UI. Add your RTMP link, choose layout and go on air! 🌟

Since we want to test with the maximum amount of users each of you will be given access for 7 days and we'll limit it to 10 testers per week, probably 4 weeks in total. If you provide valuable feedback we'll be glad to extend it for you of course.

If the first week doesn't reveal any problems we'll start unlocking options, first three being background image, multiple destinations and own logo. During the whole testing stage the amount of people in a stream will be limited to 2, you can choose between a "solo" layout and an "interview" one.

Faster connection and new languages

Last week you may have seen our tool asking to reload the page because of a new protocol version. That almost unnoticed update changed the way all your users connect to a room with several people in it, turning that process from a partially serial to a fully parallel.

This not only speeded up entering a room but also raised a bit the recommended maximum of peers in a peer-to-peer (that is without boosters engaged) mode on a solid Internet connection up to 10 for conference calls.

Another nice thing, especially for our European users: one of you was so kind and submitted interface translations to German and Swiss German languages. 🇩🇪🇨🇭

And a whisper for those who read till the end: we have started working on a free remote assistance add-on, but shhh, it's a secret! 🤫

API wrappers for Java and node.js

Since several of our users asked for API usage examples written on server JS (for node.js) and Java we have decided to add those to our collection. Published under MIT license as always.

Room boosters 🚀

It's here! 🧙 Now anyone can choose between a peer-to-peer and a server-driven webinar. Don't be limited by your Internet connection bandwidth, invite more people to the show!

Yes, we have finally started offering room boosters — dedicated media-servers that can be connected on demand to any room you choose, allowing it to allocate much more viewers than before. The first model is a 50-participants one. Soon we will add more, just let us analyze a bit how actively you are using them. And this autumn we plan to extend boosters support to our regular conference calls.

Adding boosters is simple. Whether you already have a subscription or not simply go to and either create it or add a booster in a few clicks. After that pick a domain you wish, go to "webhooks & robots" tab and link your favourite room to a newly acquired booster. One room — one booster.

So, are you in?

Webhook API

Ever wanted to get notifications to your favourite messenger when someone calls you in your white label app room? Take any action when an event is triggered in zroom, all using our new Webhook API.

Minor before a week of major

The next week we want, we need, we must release "big rooms" set of features. All focus is on that. But until then, to keep you all tuned we published a few minor improvements that you have previosly asked for.

  • users can choose whether to keep main menu always afloat or not
  • plugins visibility levels: everyone, hosts only, noone
  • domain-preset plugins — define what will be loaded for all users
  • chat image files preview on click

Basic breakout rooms plugin

We have heard your requests and added a very simple room management plugin primarily focused on breakout rooms. 🚪🚪🚪

As it's a first version its functionality is quite basic but at least you already can use it and send us your feedback on what's missing. We will continue improving this plugin bit after bit the coming weeks as it will be very handy after we release "big rooms" feature for webinars at the end of this month.
