One screen, one reply, then the next step.
No provider account is needed to build and test.- 01
Add the first screen

Add numbered choices or typed answers, then decide which screen should appear next.
- 03
Test every route
Use the phone simulator, correct unfinished paths and publish the exact version others should review.
Your resultA working browser prototype you can save, share and export.
Inside the Studio
Build the first version.
Payment and SMS steps are simulated in Studio.
Start from scratch
Use a blank canvas or copy an example.
Add the screens you need
Create menus, messages, typed input, payment and SMS steps.
Test every path
Use the phone simulator to catch unfinished or broken paths.
Save and share
Publish a fixed version, create a seven-day review link or export JSON.
Ask for a review
Send a published version to Iderwell for a feasibility check.
A feasibility review does not start provider onboarding.

Provider setup is a separate step.
Iderwell currently reviews Ghana projects that plan to use Hubtel. Hubtel controls KYC, shortcode approval and network access. Studio supports browser prototypes today; live hosting and integrations are not yet open as self-service.
Before you begin
Straight answers.
Do I need to know how to code?
No. Add screens, connect replies and test on the phone simulator.
Can I create my own flow or only edit the examples?
Yes. Start blank; the examples are optional.
Is USSD Studio really free?
Yes. The browser Studio is free in public alpha. Provider services cost separately.
Will the result work from a shortcode?
A Studio prototype is not a shortcode. A live service needs a separate production agreement and provider approval.
Do payment and SMS steps use real providers?
They are simulated in Studio. Live connections need an approved production scope and provider account.
Can I use Studio outside Ghana?
The Studio works anywhere with a modern browser. Iderwell currently reviews live integration only for Ghana and Hubtel.
Can Iderwell build the service for me?
Yes. Bring the outcome and choose Iderwell Managed Build. Live delivery is agreed separately.
