5 Best Chat API Platforms for Developers 2023

Today’s users expect a lot more from web and mobile applications. They are no longer willing to settle for basic functionality; they require speed, agility, interactivity, and dynamism on every site they visit and every app they use, regardless of whether it’s a smartphone, tablet, laptop, or desktop. So, how do you deliver the best when it comes to integrating a popular chat service that helps them communicate with each other or the brand representative? The answer is the humble chat API. Whether it’s a Twilio chat API or another live chat API, the need of the hour is an easy way to embed such functionality into your own application in order to provide that seamless and highly functional experience that your users are looking for.

What Are YOU Looking For in a Chat API as a Developer?

To that end, we’ve curated a list of the top 5 livechat API options and other chat API products that you can choose from. The key here is to look for particular aspects that can support your business. Remember: your stakeholders – in other words, your business, your internal customers, and the external end-users of the application in question – are not thinking in terms of API complexity or how hard it is to implement a solution. All they want is for their chat tools to work perfectly whenever they need it. So, as a developer, it’s up to you to worry about the nitty-gritty, such as:

  • Latency
  • API Request Success Rate
  • Uptime
  • RPM, RPS, and QPS level projections
  • Endpoint latency averages and limits
  • Errors Per Minute

… and so on. You’re the only stakeholder responsible for these metrics, which makes choosing the right live chat API or any API a crucial component of success or failure. And by that, we mean the success or failure of how well your integrations are able to serve the needs of the business as well as the end user.

With that, let’s take a look at some of the top chat API solutions available today.

#2: Vonage


As you might already know, Vonage is one of the pioneers of Voice over IP or VoIP solutions. Though not the first to the game, it does have the privilege of beating Skype to the market! Vonage bought Jumper.ai in 2021, giving it the ability to offer what it calls Conversational Commerce. 

In essence, it’s a communications API for chat services that can be integrated into your own product to provide automated responses to customer queries and even facilitate sales conversions by streamlining your sales funnel and diverting your valuable resources to other high-value tasks.

Key Features

  • Automated responses
  • Human handover to live chat agent
  • Easy-to-build chatbots
  • Conversion and engagement tools – payment gateways, appointment booking, order sync with inventory, calendar invites, etc.
  • Data capture and business intelligence mechanisms

#3: Sendbird Chat


This API-based chat service allows you to embed the power of conversational interactions with your customers into your own web and mobile applications. Used by some top companies around the world such as PayTM, Reddit, and Teladoc, Sendbird chat offers a range of capabilities for two-way private and public chat messaging, engagement, moderation, and analytics. It also offers third-party integrations for chatbot deployment and post-event webhooks.

One distinctive advantage of the Sendbird Chat API is that, similar to ZEGOCLOUD, it offers UIKit options for different platforms, making it easier to go to market with your chat integrations. The chat SDK itself is supported with samples and tutorials so you don’t have to figure everything out on your own.

Key Features

  • Private, group, and supergroup chat channels

#4: TalkJS


This API chat service comes prebuilt with a user interface SDK and includes notifications. It supports multiple chat use cases like one-to-one, group, and livechat API. It can be deployed in a number of scenarios such as marketplaces (for buyers and sellers to interact), educational platforms (to facilitate chat rooms and one-to-one chat), online job portals (connecting a hirer to a freelancer or jobseeker), and so on.

TalkJS is best known for its customizable themes where you, as a developer, get to control the layout, styling, branding elements, and other aspects of the chat API.

#5: Twilio Conversations API


Similar to Vonage’s Jumper.ai, Twilio has its own Communications API or chat API that boasts scalability to any degree and simplicity of deployment. However, it’s a little more complicated than it looks because even though it is marketed as “A single API for seamless conversational messaging”, there are several moving parts, of which chat is merely one of them.

This complexity does allow developers to build out compelling conversational and engagement platforms for their products but it requires time, effort, and more than a little relevant expertise to get the job done. The unique aspect here is the ability to blur the lines between various channels such as email, texting, MMS, Messenger, Google Business, WhatsApp, and others.

Key Features

  • Cross-channel media and text communication
  • Multichannel messaging
  • Delivery status across channels
  • Pay-as-you-go model – no subscription lock-in
  • Web and mobile SDKs and UIKits for faster deployment
  • Customizable components – messaging, user participation, etc.
  • Webhooks for intelligent escalation using Twilio Studio flows
