UpKeep is the right choice for maintenance teams wanting a proven, mobile-first CMMS with basic IoT sensor integration at published SMB-friendly pricing. Not suitable as a standalone machine health or advanced PdM platform.
Plex is the right choice for mid-market discrete manufacturers wanting machine monitoring as part of a broader cloud MES/ERP investment — particularly in automotive supply chain environments where Plex has deep vertical expertise.
