Setup beautiful event
pages in minutes

Kastio makes it easy to setup and style registration and watch pages and incorporate your clients branding. Change colors, images and text without writing a single line of code, and show or hide only the widgets your want the viewers to see.

Whitelabel pages and URL's

Your clients only see your branding and URL's on the platform pages. They'll think you built your very own webcasting platform.

Fully Responsive Interface

All pages and players scale automatically to fit any browser and device and there are no plugin downloads required.

Control access to your event with most flexible controls in the industry

With Kastio you can control access to your webcasts either through open registration or through secure password protection. Let users access your event with a simple button click, or require multi-field data collection. You can even embed the registration form on any website you like.

Record your live stream
for archive and playback

With Kastio you can record your live stream right inside the dashboard. Choose when to start and stop recording and easily download an mp4 after the recording is finished.

On-demand playback

Recordings can be made available for viewing after your event finishes. You can choose with ones to show and hide to your viewers, and they can be accessed using the same registration and authorization settings used for live.

Curate your on-demand library

While recording your live streams, you can split up your recordings into content sections and them trim the head and tail of each clip for playback. This can eliminate the need to editing and uploading after to save you time. Add section headers and categorize your clips into groups for a full organized VOD page. You can also include clips from third party video sites like YouTube, Vimeo and Wistia to complete your archive.

Registration Emails

Sent to everyone as soon as they register with a private link that gives them instant access to the event from their email.

Reminder Emails

Sent at various times before your event begins to remind attendees when your event is starting. This includes the option to send an email when you open your event alerting everything that your event is about to start.

Post Event Emails

Sent after your event ends, post event emails can be segmented between those that attended and those who didn’t. Post event emails can also be used to drive action such as filling out a survey.

What the industry is saying about Kastio

Claude Boudreau

President, Cybermediacom Inc

As a professional webcasting service provider we were considering building our own webcasting platform to better serve our clients. Before jumping in, we were evaluating some of the newer webcasting platforms on the market. It was in this evaluation period that we found Kastio. All we can say is 'wow'. They've built everything we need (and more) in their platform and it's a fraction of the cost to us building our own. Now we're running our biggest webcasts on Kastio and loving every minute of it.

Andrew Irving

Owner & Webcast Producer, IrvTech

Kastio's platform gives me the ability to produce interactive webcasts with enterprise-grade features. The platform lets me deliver on my clients' expectations for a fraction of the cost of previous previous providers. Great work, Eventstream!

Chris Kamarianakis

Executive Director, Protect Your Boundaries Inc

Kastio's integration to our e-commerce system enabled us to seamlessly sell seats to our webcast.  Their execution of the webcast during the event was flawless, garnering a 9.5 out of 10 rating from an audience.
