Top 10 Twilio Alternatives: A Guide to Choose Communication APIs for your Project

Virtual communication is becoming an integral part of our day to day lives and businesses. Especially in the time of COVID-19, startups and enterprises have no option but to make virtual communication their #1 priority. To aid this upsurge in sudden demand, communication APIs became a go-to option and today they are the most preferred technology for virtual communication. 

The need to make this scalable and inexpensive was quickly met and now there are countless options available. One of the biggest options is Twilio. It has been the top API provider for communication services since 2008. It is no surprise that Twilio is a very popular option for many businesses because of its ease of use and the whole suite of enterprise services that it offers. 

However, the most popular option is not always the best option. To make the best decision, you need to thoroughly examine several options and weigh their pros and cons. 

Confused? Don’t worry! This blog is a comprehensive list of the ten best Twilio alternatives that will help you clear your dilemma. But before you get to the list, here is a quick look at why you need a Twilio alternative in the first place?

Why do you need an alternative to Twilio?

Twilio has been helping businesses with customized communication solutions since the beginning of the API era. It earns an astounding $1.4 billion per year from its vast clientele, including Uber, Airbnb, and eBay. Twilio Flex is a cloud contact center that boasts of a massive user base. 

So, is Twilio the perfect solution for your communication needs? Um, let’s discuss. 

There are limitations to the dominance of Twilio. Let’s take an example of the European Union. The region has strict laws for data exchange with the US. According to GDPR, the data transfer across servers in the US and the EU should be safe. 

GDPR or General Data Protection Regulation helps regulate data transfers. Now, Twilio has been quite successful in the European Union. With the EU court’s latest ruling, it is now illegal to use a US-based cloud service provider, even if it has a physical server in Europe. It has led to many European companies looking towards a Twilio alternative

Another example, there was a common complaint among many SMS API users that delivery notification does not work often. What happened was the SMS was not sent from a web app, but Twilio’s system showed it as delivered. 

Similarly, some of the telecom operators in Russia use a grey scheme with Twilio, making it inefficient. What happens is there are some messages in the lot that don’t reach the desired recipient. Besides, Twilio does not indicate such mishaps. So, you may even miss the target audience and not know about it.

Another issue with Twilio is pricing; it offers communication API services at a higher price point., The total cost of ownership(TCO) with Twilio is expensive. At the same time, there are alternatives to Twilio that offer similar services at low TCO.

So, if you are thinking about what can be a good Twilio alternative in terms of technical features, efficiency, and flexibility? Here are the top ten options for you!

Top 10 Twilio alternatives

#1 Vonage


When Vonage acquired Nexmo in 2016, it was already making a significant impact on the CPaaS market with its 650 globally interconnected SMS delivery carriers. Alan Masarek, CEO at Vonage, saw this as an opportunity to establish a company that brought UCaaS and CPaaS together to offer top-of-the-line communication services. 

Today, Vonage has a user base of more than 7 billion people across 225 countries and a global web of more than 1,600 networks. Vonage combined Nexmo’s communication prowess with the video capabilities of TokBox. So, you get a suite of communication APIs that help integrate SMS, MMS, calls, videos, and social chat apps like Facebook Messenger, WhatsApp, etc. 

Vonage offers API calls with a 99.99% error-free response rate and a shorter data access turnout. Its services come with SLAs (Service Level Agreement) support. Vonage has clients like Siemens, Aramex, BlaBlaCar, Babylon, Cambly, and Glassdoor.

#Vonage as Twilio alternative

Vonage offers a unique feature – adaptive routing – not available in Twilio. This feature’s algorithm routes messages to the optimum path, enabling faster delivery to user devices. 

While Twilio employs SMS gateways that complicates the whole process, Vonage uses the carrier’s network directly. Furthermore, the use of REST APIs in Vonage makes it easy for developers to manipulate data and understand the architecture. 

Besides that, it incorporates robust protocols to its inbuilt architecture that protects your communication channel. On the other hand, Twilio uses RESTful APIs consisting of multiple layers that may expose your application to security hazards.  

#When to choose Vonage?

If you’re a business that operates majorly in the EU region, Vonage is an excellent option as it complies with the latest data regulation policy. Moreover, its voice services are available across Europe while SMS is available in the UK, Sweden, and Germany. 


  • Leverage adaptive routing algorithms for better messaging.
  • Use the new web-based console to integrate administrative functions with management reports.
  • Put to use a combination of high-end video APIs with Tokbox.
  • Get calling insights on one of the best user interfaces.
  • Integrate social chat options like Facebook Messenger, Viber, WeChat, and Line.
  • Receive free inbound SMS and one free shortcode number. 


  • Extra features come at an additional cost.
  • Video conferencing is not a part of the suite.

#2 Plivo

Twilio Alternatives(Plivo)

With a strong network of more than 1,600 global operators and connectivity in 195 countries, you can program custom calls and SMS APIs with Plivo. It offers conference calls, recording, and multi-language support for text-to-speech features to more than 50 countries and messaging in 19 countries. What’s more, Plivo offers pricing for different APIs rather than a suite of services. 

#Plivo as Twilio alternative

Despite the usual word limit, Plivo’s long message concatenation allows you to send SMSes with more than 160 characters. When a sender exceeds the cap, the phone detects it and splits it into two different SMSes. But what makes this feature more interesting is that the receiver receives these broken texts as one message. 

Although Twilio and Plivo offer extended message support for a maximum limit of 1,600 characters, it’s the free call recordings and storage that sets Plivo apart. 

#When to choose Plivo?

Plivo can help financial organizations like banks, fintech, and credit lenders to utilize browser-based call center SDK for better communications.


  • Access virtual numbers across 65 countries
  • Get instant user feedback after each call.

Twilio Alternatives(Voxbone)

Voxbone is a cloud-native Tier-1 carrier with services spanning regulatory compliance in more than 60 countries. It means that breaching new markets, and entering new international waters become easy with all the compliance and regulations in place.

Any app transmission to a carrier passes through aggregators. These aggregators connect the application with Tier-1 carriers keeping compliance with Cellular Telecommunications Industry Association (CTIA). For maintaining such compliance aggregators charge handling fees for app data. 

Some API providers bounce your application to several providers increasing the cost and degrading the quality of transmissions. Voxbone offers routing of data through fewer aggregators to lower the cost and remove lags in communication. 

#Voxbone as Twilio alternative

Voxbone helps with a SIP-capable platform that allows you to Bring Your Own Carrier (BYOC). It enables the integration of platforms with many different carriers.

RCS is a new messaging protocol used in native environments, especially for Android, to deliver a live messaging experience. What’s more, the CPaaS provider also offers solutions for fleet management and IoT (Internet of Things)-based communications.

#InfoBip as Twilio alternative

Twilio is a market leader in the communication space, but there are some weaknesses. For example, Twilio does not offer free inbound SMS, which may not be such a viable option for small businesses looking out for a solution in their budget. 

Here, we have listed Twilio alternatives that offer free inbound SMS, direct carrier connection, and even live customer support. At the same time, Twilio does not offer live customer support if you are on a free version, which means more spending on a premium plan.

All the options enlisted here are cheaper than Twilio in terms of services and customer support. As your business scales, you will need more reliable communication services for better customer relationship management, and these Twilio alternatives can help with it.

But, you will need an integrations partner for APIs to create better communication features. So, choose the best suitable communication API for your business, and make better customer journeys!
