Use it for agent memory

pumaDB is currently free while the service is early. You get small, durable JSON tables that connected agents can write to, query, update, count, list, export, and clean up explicitly.

What you can store

Notes, preferences, research, links, tasks, lightweight state, and any other JSON row up to 64 KB.

Account limits

20 tables, 1,000 rows per table, and 25 MB total storage per account.

Rate limits

30 writes per minute per key and 60 reads per minute per key.

Store

What agents can store.

Skills markdown

Reusable operating instructions, project-specific workflows, and tool notes that agents can load across sessions.

Project conventions

Repository facts, architecture notes, branch rules, naming patterns, and decisions that should not be rediscovered.

User preferences

Communication style, formatting defaults, review expectations, and other durable preferences keyed by person or workspace.

Research clippings

Sources, summaries, links, comparison notes, and follow-up questions from investigations that continue over time.

Task state

Open threads, blockers, handoff notes, pending commands, and lightweight status records for long-running work.
