The honest brief
Relevance AI
Prices on 'actions' with unlimited agents on every tier, so cost tracks work done rather than per-agent headcount.
- Unlimited agents on all tiers
- No-code multi-agent 'workforce' builder
- BYO-LLM on paid plans
- Library of tools and triggers
- Action-based billing can be opaque
- Cloud-only, no self-host
- Governance depth still maturing
Voiceflow
Visual no-code canvas that designers and PMs can build on alongside engineers — used by 130k+ people including Fortune 500 teams.
- Visual builder for chat and voice agents
- Deploy to web, phone, or any channel
- Multi-model (OpenAI, Anthropic, Google)
- Built-in knowledge base / RAG
- Scales to enterprise volumes
- Advanced/scaled usage gets pricey
- Credit-based pricing can be hard to predict
- Less code-level control than SDK frameworks
- Steeper curve for complex flows
