The successor to the OktaToEntra PowerShell module. Same problem - discovering what lives in Okta, planning the order of a migration, and tracking each app through to completion - handled in a browser rather than a console.
It is designed to be self-hosted, so the Okta and Entra credentials it needs never leave the environment that owns them.
The app is at a deployable state and is currently going through further testing and QA. The source is private for now, with the intention to open source it so others can stand up their own instance.
