Microsoft Entra ID Emulator
Stateful Microsoft Entra ID emulator for OAuth 2.0, OpenID Connect, client credentials, and a curated Microsoft Graph subset covering users, mail, calendar, and OneDrive.
Create an instance

Each instance is isolated, stateful, and addressable at its own host. The server generates an unguessable name; an optional {"instance":"<prefix>"} body adds a readable prefix.

curl -s -X POST https://microsoft.emulators.dev/_emulate/instances

Hosted deployments create instances lazily when the returned URL is first used. The instance URL is a capability: anyone who has it can read and modify the instance, so save the returned URLs. Never store real secrets in an emulator.

Sample instance host: https://microsoft.your-instance.emulators.dev
