Twilio Flex is a programmable cloud contact center built on Twilio's communications infrastructure. Unlike pre-built help desk tools, Flex is a developer-first platform where engineering teams build custom contact center experiences using Twilio's APIs, SDKs, and React-based UI framework. Flex supports voice, SMS, WhatsApp, webchat, Facebook Messenger, and custom channels through Twilio's programmable APIs. Pricing is $1/active user hour or $150/named user/month (Twilio, 2026).

Converge is a messaging-first inbox at $49/month flat for up to 15 agents. The fundamental difference: Twilio Flex is a developer toolkit for building custom contact centers; Converge is a ready-to-use messaging inbox. Flex requires engineering resources; Converge requires zero code.
