OpenClaw
OpenClaw is a free, open-source autonomous AI assistant developed by Peter Steinberger, released November 2025. Unlike conversational AI tools (ChatGPT, Claude), OpenClaw runs as a persistent local daemon that initiates actions independently via its Heartbeat system (cron-scheduled autonomous tasks). Users interact through messaging platforms (WhatsApp, Telegram, Slack, Signal) rather than a dedicated app. The agent maintains persistent memory in plain Markdown files and supports 50+ integrations. With 234K GitHub stars and 300-400K users by early 2026, it represents a shift from conversation-as-interface to agent-as-infrastructure. In February 2026, Steinberger announced joining OpenAI, with the project moving to an open-source foundation.
