About Flex USSD

USSD software should be easier to ship, and safer to operate.

Flex USSD gives teams a visual way to design mobile services, test the journey, publish to providers, and export code when engineering needs full control.

Our focus

Simple on the surface. Serious underneath.

Every major feature maps to one job: plan the flow, prove it works, launch it safely, or hand it to developers.

Accessible mobile services

USSD reaches customers without data, smartphones, or app installs.

Production discipline

Callbacks, sessions, permissions, usage controls, and validation are part of the workflow.

Developer-friendly when needed

Teams can build visually, then export code when they want to own the runtime.
