Small, focused tools that just run in your browser.
No backend, no telemetry. You use your own account, your browser talks to Microsoft directly.
In this repo
SPOTrim Open source
Find stale SharePoint and OneDrive sites in your tenant, see who owns them, when they were last touched or viewed, and decide what to clean up.
DupedDevices Open source
Find duplicate device registrations in Entra ID, decide which one to keep, and disable or delete the rest. Optional grace period using extension attributes so you can disable now and delete safely later.
SPNRoleMgr Open source
Browse every service principal and managed identity in your tenant and inspect or change their API permissions. Same workflow as Entra's "Add a permission", but works for SPNs that have no app registration in your tenant.
