jamjet vs initrunner
jamjet: JamJet is an action-control plane for AI agents that enforces safety policy across hooks, guardrails, MCP gateways, SDKs, and custom runtimes. It blocks unsafe tool calls, requires human approval for risky actions, caps costs, and provides a durable audit trail. One policy file works everywhere, supporting frameworks like Claude Code, OpenAI Agents SDK, LangChain, and more.; initrunner: InitRunner lets you define an agent in one YAML file, chat with it, run it autonomously, and deploy it as a daemon triggered by cron, file changes, webhooks, or Telegram messages. It supports multiple execution modes, built-in memory, cost controls, multi-agent orchestration, and security features. Built on PydanticAI.
