ManageEngine OpUtils vs Monsoon
Both stand on ip address management software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan AndroidAPIiPhone+4
OpUtils brings IP address management, switch-port mapping, diagnostics, and security controls together, with browser and mobile access. Its free edition is narrowly scoped, and IPAM does not assign addresses to devices.

Choose Monsoon if you want a free, open-source, self-hosted platform that brings DHCPv4, DHCPv6, and IPAM together with APIs and migration tools. Look elsewhere if you need LDAP authentication, passive rogue-DHCP sensing, or broadly scoped high availability.
