pumaDB - a small hosted memory layer for AI agents

What it does

pumaDB is a lightweight, hosted memory layer designed for AI agents. It provides a simple shared place for agents to save and reuse notes, facts, preferences, project context, transcripts, task state, and other useful memory. No database setup, vector DB, or infrastructure to manage. Agents can store and retrieve JSON rows via a hosted MCP server or a server-side REST API.

Who it is for

pumaDB is for developers building AI agent workflows that need durable, cross-session memory without the overhead of managing a database. It targets users of agent platforms like ChatGPT, Claude, Codex, and OpenClaw, as well as server-side applications. The product is positioned for small-scale use, with account limits of 20 tables, 1,000 rows per table, and 25 MB total storage.

Why it matters

Most AI agent workflows lose useful context between sessions, tools, and chats. The usual fixes are either too manual (copying notes into docs) or too heavy (setting up a database, vector store, or custom RAG stack). pumaDB offers a middle ground: a hosted, zero-setup memory layer that is deliberately small and explicit, with safety features like version history, rate limits, and scoped table limits. This makes it easy for agents to remember user preferences, project conventions, research clippings, and task state across sessions.

Launch signal

pumaDB launched on Product Hunt on the day of this profile, with 67 followers. The launch positions it as an AI Infrastructure Tool and AI Database.

Brand and naming

The name 'pumaDB' is short and punchy, but the 'puma' animal metaphor doesn't clearly connect to memory or databases, making it less intuitive. The domain pumadb.ai is memorable and available, which is a plus. The tagline and website clearly position it as a lightweight, hosted memory layer for AI agents, emphasizing ease of use and safety, which is a strong, focused positioning.
