Top 5 Twilio alternatives & competitors

Twilio is one of the more widely used CPaaS platforms available today, however it isn’t without its faults, which through steady usage of the software, becomes very apparent. 

Startup businesses attempting to bolster their performance by using voice and SMS APIs may find that Twilio comes at a higher cost that isn’t manageable due to budget constraints. 

Twilio lacks free incoming SMS and free support team coverage, which comes at a cost to your business. CPaaS competitors have taken these drawbacks into consideration and added robust features with more user-friendly interfaces that may give Twilio a run for its money.

The Twilio competitors outlined in this article are just a few of the solutions that are currently available on the market. Take your business’ needs into account when considering these Twilio alternatives and determine whether any of them will be a good fit for you.

Twilio alternatives

Twilio offers a multitude of benefits that include SMS and MMS messaging, voice calling, video communication and email. Additionally, the platform offers omnichannel communication support and local toll-free phone numbers for both mobile and national communications. Twilio also employs short codes to handle high volume MMS and SMS texting, which lifts some of the burden that your team may otherwise feel the pressure of. 

Where Twilio falls short is its lack of coverage in some countries, non-free SMS messaging, and the need for more in-depth customer service and support. The cost of Twilio may also be outside the budget of some smaller startups, meaning a competitor may be the answer. 

Some alternative vendors include:

Vonage API: Best for the authentication of APIs and the verification of number insights. 

MessageBird: Best for omnichannel inboxes. 

Bandwidth: Best for call transcriptions, text-to-speech, and recording. 

Sinch: Best for SDK development.  

Telnyx: Best for networking APIs and world-wide data transfer.

Twilio limitations

Twilio is commonly known to connect organizations with their client base on their preferred platform, but they are not alone in offering these services.

Choosing the right alternative to Twilio

There are a large number of API and communications platforms for competitors to choose from when Twilio doesn’t seem like the perfect platform. 

When it comes to simplifying SMS and MMS messages with many popular social media platforms into a single API, Vonage API is a good alternative and for flexibility, MessageBird and its ability to provide an omnichannel inbox for connecting with customers is a no-brainer. 

If your business needs additional development options through customizable APIs, Sinch would be a good bet for you. Meanwhile, Bandwidth has an advantage over Twilio when it comes to its ability to provide live text message notifications and detailed insights, which developers will find very useful. 

Finally, Telnyx trumps Twilio by offering free 24/7 customer support, in-app calling and texting, and is one of the cheaper communications platforms in today’s market.
