OpenClaw

OpenClaw, published by PSPDFKit founder Peter Steinberger, goes by the nickname "Molty." In January 2026, the project exploded in popularity on GitHub, surging from thousands of stars to 60,000 stars within 72 hours. The reason OpenClaw gained such strong support is straightforward: its design philosophy of "an AI agent that runs without sending data outside, as long as you bring your own API key." No subscription required. You can choose your model from OpenAI, Anthropic, or a local LLM. It connects to more than 50 channels including WhatsApp, Slack, and smart home devices, and runs continuously in the background 24 hours a day. What makes it technically interesting is that the agent can write new Skills on its own. When instructed to "automate this task," it autonomously writes the code needed for execution and reuses that Skill going forward. The community Skills marketplace has over 5,700 skills published, allowing functionality to be added with a single install. Context retention across sessions (long-term memory) is another key feature. Since it remembers user preferences and past conversation content when entering the next conversation, there is no need to explain everything from scratch each time.
