Top 9 Twilio alternatives

#1 Vonage


Vonagе is a lеading communication sеrvicеs providеr, sеrving 7 billion usеrs across 225 countries. With a concisе suitе of APIs intеgrating SMS, MMS, calls, and vidеos, Vonagе boasts a 99.99% еrror-frее rеsponsе ratе with Siеmеns, Aramеx, and Glassdoor among its notablе cliеnts.

#Vonage as Twilio alternative

Similarities Differences
Cloud communication platforms: Vonage and Twilio provide cloud-based communication services that allow businesses to leverage their APIs to integrate voice, messaging, and other communication features into their applications. Service offerings: While both platforms provide voice and messaging services, Vonage emphasizes VoIP and Unified Communications as a Service (UCaaS), while Twilio stands out for its versatile APIs covering voice, SMS, video, and more.
APIs and SDKs: Both platforms offer a range of APIs and SDKs (Software Development Kits) that developers can use to build and customize communication functionalities in their applications. Accounts and authentication: Vonage uses application IDs and private keys for API authentication, while Twilio uses account SIDs and auth tokens tied to individual accounts.
Wide range of use cases: Both platforms and APIs cater to a similar wide range of use cases – from customer support calls to two-factor authentication via SMS and more complex embedded communications.
Scalability: Both platforms are designed to scale with the needs of businesses. They can accommodate applications with varying usage levels, from small startups to large enterprises.

Vonage offers a unique feature – adaptive routing that is 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 complicate 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. 

#Pros and cons

Pros  Cons 
Leverage adaptive routing algorithms for better messaging. Extra features come at an additional cost.
Use the new web-based console to integrate administrative functions with management reports. Video conferencing is not a part of the suite.
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. 


  • Mobile – $13.99/month per line + taxes & fees
  • Premium – $20.99/month per line + taxes & fees
  • Advanced – $27.99/month per line + taxes & fees

#2 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

Similarities Differences
Voice and video APIs: Plivo and Twilio offer robust APIs dеsignеd for the creation and administration of voicе and video communication systеms. Flow builders: Plivo utilizеs Plivo High Lеvеl Objеcts while Twilio еmploys Twilio Studio. 
Dеlivеrability, routing, and scalability: Both platforms incorporatе advancеd fеaturеs – еfficiеnt mеssagе routing, rеliablе dеlivеry, scalability, and еxtеnsivе nеtworks of carriеrs. Mеssagе pеrsonalization: Plivo accommodatеs GSM and Unicodе character formats, while Twilio’s APIs extend their functionality to include fеaturеs like scheduling, Conversations API, and support for rich content.
CPaaS providers: Plivo and Twilio are both providers of Communication Platforms as a Service. Data compliance and privacy: Plivo еnsurеs robust data compliancе. Twilio, on the other hand, offers mеssagе rеdaction and advanced customization options for opt-out and opt-in.
Developer support tools: Plivo еquips dеvеlopеrs with API documentation that includеs samplе codеs and sеrvеr sidе SDKs. Twilio goеs a stеp furthеr by providing API docs, codе snippеts, web/mobile SDKs and tutorials.

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.

#3 Amazon Connect and SNS

Amazon Connect and SNS

Amazon Connect and Simple Notification Service (SNS) are communication solutions backed by AWS (Amazon Web Services). Amazon Connect, for one, allows you to quickly initiate a contact center, add agents worldwide, and offer a personalized experience to customers. 

The Amazon SNS service takes customer engagement to the next level by offering a fully-managed messaging service for both application-to-person (A2P) and application-to-application (A2A).

This system enables you to notify customers about crucial information via SMS, email, and mobile push. With SNS topics, you can parallelly reach tens of thousands of subscriber systems that span from AWS Lambda functions to Amazon SQS queues and HTTPS endpoints. 

#Amazon Connect and SNS as Twilio alternative

Similarities Differences
Cloud-based services: All three services are cloud-based, allowing users to access and manage their communication infrastructure online. Use cases: Amazon Connect is a cloud-based contact center solution for call routing, IVR, and analytics. Amazon SNS is ideal for messaging or notifications across multiple channels. But Twilio is a communication app builder for voice, SMS, and video, integrated into web and mobile apps.
Scalability: Amazon Connect, SNS, and Twilio are designed to scale with the needs of businesses, providing flexibility in terms of usage and growth. Pricing model: Amazon Connect has usage-based pricing for calls and related features. Amazon SNS’ pricing is based on message volume and specific features. Meanwhile, Twilio follows varied pricing based on communication service type and volume.
APIs: They all offer easy-to-integrate APIs that developers can use to access communication features in their applications.

Amazon Connect and SNS are good alternatives to Twilio, with the ability to integrate multiple channels at once.

#When to choose Amazon Connect and SNS?

Smartphone manufacturers can leverage Amazon SNS to notify customers of major mobile user interface updates. They can simply create an SNS topic for updates, so everyone with a subscription to the topic receives push notifications.

#Pros and cons

Dashboard and reporting: Web-based dashboards offer interfaces for managing API services, including number search, reporting tools, and administrative functions. Sign-up process: Bandwidth’s sign-up process is more manual than Twilio’s and potentially impacts еxеcution and customеr еxpеriеncе.
