osTicket — open source alternative

Classic open source support ticket system used by many SMBs.

Strengths

  • Straightforward PHP/MySQL stack — runs on any LAMP host.
  • Mature — stable for over a decade.
  • Hosted SaaS available if you want support revenue funded.

Weaknesses

  • UI feels dated compared to Zendesk or newer entrants.
  • No native multi-channel (live chat, social) without plugins.
  • Development pace is slower than rivals.
