klanex is the asynchronous execution layer between LLM agents and production APIs. Here's how it lines up against the tools and patterns teams use to run agent tool calls today — including where the honest answer is "different layer, use both."
Composio is an integration catalog with managed OAuth. klanex is a reliability engine for any API. Different layer — durable retries, schema gating, idempotency, and replay a catalog doesn't do.
Arcade authorizes agents as real users and governs them. klanex makes each authorized call survive production. Two layers that can sit in the same pipeline.
LangChain's .with_retry() and LlamaIndex's retry helpers run in-process and synchronously. See why durable, async execution survives the agent process — and why teams run both.
The naive baseline breaks on hallucinated payloads, timeouts, naked credentials, and double-executions. See what changes with a reliability layer in between.
