Deskpro

Deskpro is a highly customizable and API-first help desk platform available as cloud or on-premise software. It consolidates email, chat, phone, and social into a single interface and offers a help center, chatbot, and SLA management. Its strength lies in its deep customization options and robust API, allowing it to be tailored to complex workflows. It serves organizations from SMBs to large enterprises and governments.

It scores decently for its power and flexibility, particularly for teams with developers who can leverage its API to build custom integrations and unique workflows not possible with off-the-shelf solutions.
