Twilio Flex Review & Benchmarks
Programmable cloud contact center platform with CustomerAI and predictive routing
Overview
Twilio Flex is a completely programmable cloud contact center platform built on Twilio global communications infrastructure. Unlike rigid off-the-shelf CCaaS suites, Flex allows software engineering teams to customize every pixel of the agent interface, every step of the routing logic, and every backend data integration.
