FAQ

Frequently asked questions.

Common questions about Agent Messenger, how it integrates with your stack, and what it costs.

How is this different from Twilio? +

Twilio gives you raw channels. Agent Messenger gives you a single agent-aware SDK across channels — plus inter-agent handoffs, audit-grade logs, and replay. Built specifically for autonomous agents, not human operators.

What frameworks do you support? +

OpenAI Agents SDK, Anthropic Claude, LangGraph, CrewAI, Mastra, Vercel AI SDK, and custom orchestrators via raw HTTP / OpenTelemetry.

Are you SOC 2 compliant? +

SOC 2 Type I in progress. HIPAA BAA available for healthcare customers. Audit logs retained 7 years for regulated industries.

How does pricing work? +

Free tier for indie developers. Team plan $99/mo. Enterprise — contact sales.

Can I self-host? +

Open-source SDK + local viewer free forever. Enterprise self-hosted backend available on Team and Enterprise tiers.

How long does integration take? +

Most teams ship a working integration in under an afternoon. Python, TypeScript, and Go SDKs all auto-discover your existing agent framework.

I have more questions — who do I contact? +

Drop us a line at hello@agentmessenger.dev — we typically respond within a few hours.
