## Server-side SDKs
Server-side SDKs (or Server-side helper libraries) make it easy for you to use Twilio's REST APIs, generate TwiML, and perform other common server-side programming tasks. These SDKs are available in a variety of popular server-side programming languages.
## OpenAPI Specification
Twilio's OpenAPI specification empowers you with a broad set of developer tooling, ranging from Postman collections to API mocking to automatic client generation in over 40 programming languages.
## JavaScript SDKs
Twilio's JavaScript SDKs are used in the browser to create video conversations, make VoIP phone calls, or implement real-time omnichannel chat. Get started with the SDK you need.
## iOS SDKs
Our iOS SDKs enable native apps to create video conversations, make VoIP phone calls, and embed real-time omnichannel chat. Get started with the SDK you need.
