Open-source alternatives to Crisp
Crisp is a shared inbox, live chat and AI chatbot for small teams. If you would rather own the software, keep data on your own server or avoid per-seat pricing, these open-source tools tackle the same problem: answer customers 24/7. Customers expect an answer in minutes, at midnight, on the channel they chose. An AI agent can resolve the repetitive half, if it's grounded in your real answers.

Hosted vs open source: what changes
Open source swaps a subscription for setup time. Crisp is hosted, supported and updated for you; with the tools below you (or someone you hire) install, update, back up and secure them. 0 of the 6 with a setup rating here need a developer. Most can also be bought as a hosted cloud plan from the same maintainers, which is a good middle path. Check each licence before you build on it.
