# Alternatives and comparisons

> How ECP (Execution Control Protocol) compares to popular agent frameworks and orchestration stacks.

# Alternatives and comparisons

If you’re evaluating **ECP (Execution Control Protocol)**, these short comparisons are designed to help you quickly place it in the modern agent stack.

ECP is a **runtime specification** for execution environments: what an agent can access (tools, data mounts), what is allowed (policies), and how execution is orchestrated and audited. It’s meant to **integrate with** frameworks you already use, not replace them.

## Comparisons

* [ECP vs LangChain](/alternatives/ecp-vs-langchain) — where orchestration ends and execution control begins
* [ECP vs OpenClaw](/alternatives/ecp-vs-openclaw) — host `security` mirror, tool gates, and why agent frameworks still need a hard execution boundary
