The OpenAI Agents SDK offers the simplest path to building agents — if you are committed to OpenAI models. Klawty is provider-agnostic, routing across 200+ models with cost-aware 5-tier selection, native channels, and production-grade security.
| Feature | OpenAI Agents SDK | Klawty |
|---|---|---|
| Vendor | OpenAI (locked) | Any provider via OpenRouter |
| Models | OpenAI only | 200+ models (5-tier routing) |
| Multi-agent | Handoffs between agents | Unlimited coordinated with proposals |
| Channels | None | 20+ native |
| Security | Guardrails (input/output) | Docker sandbox + policy + PII + integrity |
| Memory | None persistent | 6-tier + Qdrant + context threads |
| Cost control | None | 5-tier routing, daily caps, per-agent tracking |
| Self-hosted | Yes (pip) | Yes + managed option |
| Voice | Realtime voice agents | No voice (text channels) |
| Dashboard | None | CLI + TUI + web portal |
The OpenAI Agents SDK is the simplest way to build agents if you are already committed to the OpenAI ecosystem. It also uniquely supports realtime voice agents — something no other framework offers natively.
Klawty is the right choice when you need provider independence, cost control, production security, or native channel integrations that go beyond what a simple SDK provides.
