Peppermint

Peppermint is an open-source issue management and help desk platform offering email-to-ticket conversion, a clean web UI, webhook-driven automation, and OIDC single sign-on for integration with identity providers like Keycloak or Authentik. Positioned as a lighter alternative to Zendesk or Jira, it is deliberately lightweight enough to run on low-end hardware or a low-cost VPS, without requiring internet connectivity to function, keeping all customer and ticket data on infrastructure the operator controls. It suits small businesses, homelabs, and makerspaces that need structured support ticketing without the overhead of enterprise ITSM suites.
