Overview
In the rapidly evolving landscape of AI agents, two distinct needs have emerged: persistent memory and humanlike behavior. pumaDB and Humalike address these needs from different angles. pumaDB is a lightweight, serverless memory store that lets agents save and retrieve JSON records across sessions without any database setup. Humalike, on the other hand, is building behavioral APIs that give agents social skills, theory of mind, and proactiveness – making them feel like they belong in a room with humans.
This comparison will help you understand which product fits your use case, or how they might work together.
Feature Comparison
| Feature | pumaDB | Humalike |
|---|---|---|
| Core Purpose | Durable memory storage for AI agents | Behavioral infrastructure for humanlike AI agents |
| Primary Interface | Hosted MCP (Streamable HTTP) + REST API | Behavioral APIs (coming soon) – model-agnostic components |
| Memory Model | Structured JSON rows in tables with version history | Social memory that tracks norms, opinions, and behavior |
| Setup Complexity | Minimal – connect via MCP URL or REST key | Requires integration with behavioral APIs |
| Target Use Cases | Any agent needing persistent memory | Gaming NPCs, AI coworkers, therapy, companions, ed-tech, humanoids, communities |
| Safety & Review | Version history, natural edits, viewer links, rate limits | SOC 2 Type II and ISO 27001 in progress; encrypted data |
| Integration | Works with Codex, ChatGPT, Claude, OpenClaw, any MCP client | One-shot Hermes integration for turn-taking, persona, theory of mind |
Pricing
pumaDB offers a generous free tier: 20 tables, 1,000 rows per table, and 25 MB total storage. Rate limits are 30 writes per minute per key and 60 reads per minute per key. No credit card is required to start, making it easy to experiment.
Humalike provides $20 in free credits for new accounts, with no card required. However, the full pricing for their behavioral APIs has not been disclosed yet, as the APIs are still in development.
Pros and Cons
pumaDB
Pros:
- Extremely easy to set up – no database or infrastructure management
- Dual interface (MCP + REST) covers both agent and server-side needs
- Built-in version history and natural language edits for safe memory management
- Lightweight and focused on durable JSON storage for agents
Cons:
- Limited storage capacity (25 MB total) may not suit large-scale applications
- No built-in behavioral or social intelligence – purely a memory store
Humalike
Pros:
- Unique focus on making agents socially intelligent and humanlike
- Model-agnostic APIs that compose across use cases (gaming, therapy, companions, etc.)
- Includes theory of mind, social observability, and social signals – advanced features
- Free credits to start and SOC 2/ISO 27001 compliance in progress
Cons:
- APIs are still 'coming soon' – not yet fully available for production use
- Requires more integration effort compared to a simple memory store like pumaDB
- Pricing beyond the free tier is unclear
Verdict
Choose pumaDB if you need a dead-simple, durable memory store for your AI agents without any infrastructure overhead. It's perfect for saving preferences, project context, task state, and other JSON records across sessions. Choose Humalike if you want to build agents that feel human and socially aware, especially for interactive or community-driven use cases like gaming NPCs, AI companions, or therapy agents. They can also complement each other – pumaDB for memory, Humalike for behavior – giving you both persistence and social intelligence.
