NanoMDM

NanoMDM is an open-source (MIT) Apple Mobile Device Management server and Go library from the MicroMDM GitHub organization. It implements the core Apple MDM protocol: device check-ins, the command queue, APNs pushes and an HTTP API for queuing raw Plist commands, with a MicroMDM-compatible webhook for processing device responses. It is designed for horizontal scaling with almost no local state; enrollment and command data live in a storage backend (a built-in file key-value store, MySQL or PostgreSQL). It supports multiple APNs topics, which makes it potentially multi-tenant, can target one command at many enrollments at once, and has a migration endpoint for moving enrollments between storage backends or MDM servers. NanoMDM is deliberately one component rather than a complete product. You run it alongside a SCEP server (for example micromdm/scep), a reverse proxy that terminates TLS, and your own enrollment profiles. It has no web console, no VPP and no ADE (DEP) API access, although ADE enrollments are supported. Other projects in the same Nano suite fill those gaps: NanoDEP for the ADE API, NanoCMD and KMFDDM for workflows and Declarative Device Management, and NanoHUB, which combines NanoMDM, NanoCMD and KMFDDM into a single server. The MicroMDM maintainers put MicroMDM v1 into maintenance mode in 2025, ended its support at the end of 2025, and name NanoMDM and the Nano suite as the official migration path; the micro2nano tools help move existing enrollments. NanoMDM ships as release zips and a Docker image on GitHub Container Registry. It is aimed at engineers who want to build their own MDM tooling; MSPs without in-house developers will find a commercial or full-featured open-source MDM easier to run.
