What Substly is

Substly is a SaaS management platform for small and medium-sized businesses that need visibility into software subscriptions and usage. Its discovery engine uses Google Workspace and Microsoft Entra ID integrations plus browser extensions to identify applications. The Monitor plan covers multi-source discovery, Shadow IT detection, contract and cost management and renewal alerts. Substly can notify employees when they open applications marked as unapproved. Optimize adds individual-level usage data for unused-license detection, employee offboarding and Microsoft 365 license monitoring and optimisation. The company says offboarding can save up to 90% of offboarding time. Web access is paired with extensions for Chrome, Edge, Safari and Firefox. Listed security details include encrypted customer data stored in the EU for GDPR compliance, with custom plans choosing EU or US hosting. Google or Microsoft single sign-on and authenticator-app multi-factor authentication are listed. Monitor costs $130 a month and Optimize $260 a month, both billed monthly.

Substly suits small and medium-sized businesses tracking SaaS use, subscriptions, renewals and employee access. It is useful for teams managing Microsoft 365 licences and offboarding workflows.
