OpenClaw
An open-source personal assistant that runs on your own machine and meets you in Discord, iMessage, Slack, Telegram, WhatsApp, and 20+ channels.

Best for
People who want a self-hosted assistant with memory, tools, and messaging integrations they control.
Why it deserves attention
OpenClaw runs a Gateway on your laptop or server and connects it to the chat apps you already use, with native apps for macOS, iOS, Android, Windows, and Linux. State, memory, and credentials stay on your hardware; models and agent harnesses such as Claude, Codex, or local models are swappable plugins. Skills and plugins add tools, and the same setup scales from a personal assistant to a shared team deployment. It is MIT licensed, stewarded by a nonprofit foundation, has no paid tier or hosted service, and has roughly 394,000 GitHub stars. Setup and permission boundaries take real care, especially when the assistant can act on your behalf.
