What Amazon Lex does well
- Deep integration with the AWS ecosystem — Connect, Lambda, Kendra, Bedrock, S3
- Supports both text and voice channels including IVR and Alexa
- Extremely flexible intent and slot configuration for any domain
- Leverages Amazon's NLU technology proven at Alexa scale
Why teams look for an alternative
- Requires AWS engineering to build any production-quality agent
- Per-request billing adds cost unpredictability at scale
- No native ecommerce integrations — every order action is a custom Lambda
- No built-in help desk or shared inbox for human handoff
- Total solution requires assembling multiple AWS services, increasing complexity and cost
