Hosted vs open source: what changes
Open source swaps a subscription for setup time. AIGPTZero is hosted, supported and updated for you; with the tools below you (or someone you hire) install, update, back up and secure them. 5 of the 7 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.
