| **Environment isolation** | 3 environments (dev, prod, eval) | No | Staging + production | No | No | No | Limited |
| **Dashboard** | Real-time admin UI (13 modules) | Visual canvas + analytics | Visual studio + analytics | No | LangSmith UI (separate) | No | Visual workflow editor |
| **Deployment** | Managed (`struere deploy`) | Cloud publish | Cloud or self-hosted | Self-hosted | Self-hosted | Self-hosted | Self-hosted or cloud |
| **Custom tools** | TypeScript handlers on sandboxed Fly.io | Visual action blocks | JavaScript code cards | Python functions | Python/JS functions | Python functions | JavaScript code nodes |
| **Conversation persistence** | Built-in threads with channel context and message history | Built-in conversation state | Built-in conversation state | Memory modules (short/long-term) | Memory classes (buffer, summary, entity) | Chat history | No (stateless) |
| **Open source** | No | No | Partially (v12 MIT) | Yes (MIT, 50k+ stars) | Yes (MIT, 100k+ stars) | Yes (MIT, 35k+ stars) | Yes (fair-code) |

## Pricing Models

| Platform | Model | BYOK |
|----------|-------|------|
| **Struere** | Credit system + BYOK with 3-tier key resolution | Yes (org direct key → OpenRouter key → platform credits) |
| **Voiceflow** | Free tier + per-interaction paid tiers | No |
| **Botpress** | Free tier + usage-based | Limited |
| **CrewAI** | Open-source (free); CrewAI Enterprise for managed hosting | Yes (direct LLM keys) |
| **LangChain** | Open-source (free); LangSmith paid for tracing/eval | Yes (direct LLM keys) |
| **AutoGen** | Open-source (free) | Yes (direct LLM keys) |
| **n8n** | Self-hosted (free); Cloud per-execution pricing | N/A (workflow tool) |

## When to Choose Each

**Struere** — Choose when building production AI agents that need a built-in data layer, fine-grained RBAC, multi-channel support (WhatsApp, web, API), environment isolation, and a managed deployment pipeline. Best for developer teams building business automation agents with sensitive data and complex permission requirements.

**Voiceflow** — Choose when product teams and designers need to prototype and deploy conversational agents without writing code. Best for teams that prioritize visual flow design, rapid iteration, and broad channel deployment over programmatic control.

**Botpress** — Choose when teams with mixed technical and non-technical members need a visual builder with code escape hatches and a large integration ecosystem. Best for teams that want self-hosted control with a visual development experience.

**CrewAI** — Choose when Python developers need multi-agent orchestration for task pipelines, research automation, or batch processing. Best for teams with existing Python infrastructure that want a lightweight framework for agent collaboration patterns.

**LangChain** — Choose when building custom LLM applications that require maximum flexibility in chain composition, retrieval patterns, and model selection. Best for developers who want the largest ecosystem of integrations and community resources.

**AutoGen** — Choose when building experimental multi-agent systems with complex conversational patterns, group chat, or research prototypes. Best for teams exploring novel multi-agent architectures.

**n8n** — Choose when building deterministic workflow automation that connects external services with fixed logic. Best for operations teams that need reliable, repeatable automation without LLM reasoning costs.
