Top 3 Alternatives to Twilio Video SDK 2023

Twilio is a public company listed on New York Stock Exchange since August 2016. It provides various cloud-based SDKs, including sms, voice, and video, to allow clients to integrate into their own applications. Actually, there are various similar global cloud services providers such as ZEGOCLOUD which provides real-time video communication to make real-time video calls or even interactive live streaming in the apps.

What is a Video SDK

SDK means a Software Development Kit, a collection of software development tools in one installable package. The description is a bit abstract. You can think of SDK as a collection of software development modules built into a library file, static or dynamic, and you can use it by calling the interfaces exposed to developers.

Video SDK refers to the kind of SDK you can use to conduct real-time interactive video calls. Real-time video SDK cannot work without a network, therefore, it has to contain a network transmission module. It won’t work as a standalone module, it has to connect with other apps for real-time video calls.

There are two kinds of video SDK. One kind transmits real-time media data in a peer-to-peer manner like WebRTC. WebRTC video SDK allows you to make a video call with another user without a server cluster. WebRTC does have some kind of servers like TURN and STUN servers. However, they are optional and are not designed for media data transmission.

The other kind transmits real-time media data with leverage on a data acceleration network like ZEGOCLOUD. ZEGOCLOUD built a proprietary data acceleration network called MSDN (Massive Serial Data Network) and uses it to guarantee the service quality of video calls like smoothness, low latency, and high definition. With the acceleration network deployed on the cloud, real-time video communication service providers like Twilio and ZEGOCLOUD will provide the video SDK as a PaaS. Developers can integrate the video SDK and use the service easily.

The Must-Have Video SDK Features

Different video SDKs contain various features for differentiation. However, there are some basic features that a typical video SDK must have.

First of all, the video SDK must allow one-on-one or many-to-many interactive video conversations. Once participants join a discussion, they should be able to enjoy a quality voice and video communication experience.

Secondly, the video SDK must guarantee conversational voice quality, including acoustic noise suppression, acoustic echo cancellation, and automatic gain control. These basic but important techniques ensure that you can hear voices that can almost replicate offline experiences.

Thirdly, the video SDK must ensure critical user experience including low latency, smoothness, and high definition. If the latency is lower than 300ms, you can feel no lagging and speak naturally with other participants. An appropriate frame rate is important for smoothness. In terms of motion pictures, the frame rate is 24 FPS. The high-definition feature allows adjustments of video picture quality. A 720p resolution should provide acceptable video quality on a smartphone screen. However, the resolution must be adjusted to 1080p to ensure a quality user experience on a PC screen.

Fourthly, some support and supplement features must include recording, streaming mixing, and monitoring. For example, ZEGOCLOUD’s video sdk allows video recording on the cloud or on-premises; it also allows you to mix multiple streams into a single stream for broadcasting purposes; ZEGOCLOUD also provides a backend monitoring dashboard that allows you to monitor the system from various aspects including user, room, stream, device, etc.

What is a PaaS and aPaaS

Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.

In our context, ZEGOCLOUD and Twilio deployed the whole service on the cloud as a PaaS and exposed the video SDK as endpoints to allow developers to integrate and use it on the go. It is like using electricity, you plug in, pay the bill, and use it, and you don’t have to worry about how it works. This is the great thing about PaaS.

To developers, the video SDK exposed by a PaaS is just lines of code, and there is still some distance from the application-level GUI and business logic. Some clients would rather focus on their own business and fully trust ZEGOCLOUD’s technology and demand a high level of encapsulation of the video SDK. In that case, we have launched some scenario-based solutions, such as the solution for online transactions and recording in the finance industry. The solution encapsulates partial application-level business logic and provides some GUIs. We call this kind of PaaS an aPaaS, i.e. Application Platform as a Service.

Why Should We Need Alternatives to Twilio Video SDK

Twilio was founded in 2008 and its main business is to provide SMS service. In 2016, the company obtained real-time communication technology through the acquisition of Kurento Technology.

Twilio entered into a definitive agreement to acquire proprietary WebRTC media processing technologies built by the team behind the popular Kurento Open Source Project. Upon completion of this transaction, the team behind Kurento joined Twilio to lead the integration of the new technologies and enable the development of advanced video in web and mobile applications.

Even though Twilio developed its video SDK service through the acquisition of Kurento Technology, its video SDK is still far from being able to match its SMS service.

In addition, as a common practice in the industry, companies tend to integrate at least two vendors’ solutions and balance the traffic load depending on their performance. For some regions, one vendor’s video SDK might perform the best, while for other regions, the other vendor’s video SDK might work better. It is also wise to have an alternative solution as backup or load balancing.
