nab vs initrunner

nab: nab is a single Rust binary that fetches any URL as clean markdown using your real browser cookies, transcribes audio and video on-device, and watches URLs for changes. It runs as a CLI, an MCP server and a Claude Code plugin with no cloud backend.; 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.
