USSD app builder
USSD apps your customers can dial from any phone.
Dial *384# on a $10 feature phone — no internet, no app — and your service answers. Design the menu on a visual canvas, test it in the built-in simulator, and go live through your aggregator.
- 01No internet required — USSD works on every GSM handset, smartphone or not.
- 02Banking, agriculture, public services — self-service menus for markets where USSD is how business gets done.
- 03Same canvas as your chatbots — one platform, one team, every channel.
How it works
From menu sketch to live shortcode service
Design the menu flow
Drag menu, input, datastore and API nodes onto the canvas. Branch on user choices, validate entries, and call your own systems mid-session.
Dial it in the simulator
The in-browser phone runs your USSD menu exactly as a handset would — every branch, every timeout, with live logs for each step.
Publish and connect your gateway
Validation runs first, then you get a live URL. Paste it into your aggregator — Africa's Talking, Twilio, or Infobip — and you're live.
Built for production USSD
Everything a real USSD service needs
Menu & input nodes
Numbered menus, free-text input with validation and retries, and pagination for long lists.
APIs mid-session
Check balances, create records, or verify customers against your backend while the session is open.
Datastores built in
Persist registrations, orders and survey answers without standing up a database.
SMS follow-ups
Send confirmations and receipts by SMS through Twilio, Africa's Talking or Infobip when the session ends.
Validation before deploy
Structural linting catches dead ends and unwired branches before a customer ever dials in.
Versioned publishing
Every publish is a version. Roll back instantly if a change misbehaves.
- Need chat too? The same flow can serve WhatsApp, web chat and more →
Your customers are already dialing.
Build your first USSD menu in minutes and test it before you ever touch a gateway.
