Building Zero Cost Openclaws

This guide argues that a fully autonomous OpenClaw agent can be built with minimal monthly cost by combining decentralized hosting with free-tier APIs, while still requiring attention to infrastructure, security and model behavior. It recommends deploying on Aleph.im's decentralized VPS (Debian 12, 7.5GB RAM), which offers one month of free credits, and running the agent under a restricted user with 600 permissions on config files. It warns that autonomous agents can stall when searching directories like node_modules, and that misconfigured keys such as "Unrecognized key" errors cause silent crash loops. It also advises using Google's text-embedding-004 for free semantic memory, configuring fallback model chains, and scanning third-party SKILL.md files for malicious instructions before use.
