Botpress vs Retell AI

Botpress: Subscription plus conversation packs and AI usage beyond the included allowance. Plus packs cost $65 per 100 conversations; Team packs $50 per 100. Paid plans automatically add conversation packs and $10 AI credit grants near the limit. AI and human-assisted conversations both count; added packs recur until removed. Retell AI: Voice cost combines infrastructure, speech, model, telephony and optional per-minute features. Chat is charged per AI message. Phone numbers cost $2/month; 20 concurrent calls are included, with additional concurrency $8/month each. Use the selected configuration to estimate the monthly bill. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.

Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Can it cite or restrict answers to approved knowledge? What happens when the agent is uncertain? Which actions can it complete beyond answering? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Botpress: Separate AI spend can make costs less predictable; production quality depends on workflow design and model configuration. Retell AI: Telephony, model, speech and other provider costs may be separate; technical integration work is expected.
