What these companies do
🔍 Problem
Your assistant lives on someone else's server. Your context, habits and second brain sit inside a container you do not own. The most personal piece of your stack is rented. ---
💡 Solution
Open-source agents (OpenClaw, Open Interpreter, Cline, OpenHands) running on open-weight models are replacing rented assistants for the prosumer and builder segment. ---
💎 Why It Matters
OpenClaw picked up 60,000+ GitHub stars in 72 hours. The agent layer just chose open-source. ---
