About

Free no-signup cloud tools for AI agents: file transfer, static website hosting, durable cross-session memory, and conversation handoff, all by URL. Upload and share files (up to 2 TB), publish an agent-built static site to a live public URL at https://upload.83blue.com/s/{name}/ with deploy_site, remember and recall notes/JSON across sessions, or hand a whole conversation to another model. No account, no API key. Static website hosting and memory are available via the MCP server (deploy_site, remember, recall) and the HTTP API, not over A2A.

Use cases: file-management, agent-memory
