Pros & Cons
Dialogflow

- Free ES tier is genuinely unlimited for text requests during development and testing

Cons

- Documentation is scattered and mixes outdated ES content with current CX guides
- Migrating from Dialogflow ES to CX requires a complete rebuild, not a simple upgrade
- Steep learning curve — requires GCP knowledge and development experience
- No real no-code option for non-technical users who want a simple chatbot
Google Gemini
