What it does
TinyBase is a reactive data store and synchronization engine that manages structured data with automatic updates across connected clients. It's designed for real-time collaboration, offline-first architectures, and state management in applications requiring data consistency.
Who it’s for
Developers building collaborative apps, real-time dashboards, or offline-capable systems who need a lightweight, embedded data layer. It may appeal to AI agents managing shared state or coordinating multi-step workflows.
Copy-paste setup
Check these steps against the project’s own instructions before running anything.
Verify against the repo README at https://github.com/tinyplex/tinybase (opens external site) for the latest installation instructions. Typical Node.js integration: npm install tinybase. For MCP connector usage, check if an official adapter exists in the repository or consult AgentArmor's connector directory.
Risks
- No apparent production usage signal (0 weekly npm downloads suggests limited real-world deployment and reduced community vetting)
- Data synchronization logic may introduce consistency or integrity issues if not carefully implemented; verify encryption in transit and at rest
- Embedded data store could expose sensitive agent state if not properly isolated; ensure credentials and secrets are never stored directly
- Supply-chain risk: single-maintainer or small-team projects may have limited security review; monitor repository for abandoned status
- If used as an MCP connector, verify it doesn't inadvertently log or persist agent prompts, API keys, or intermediate reasoning
How to stay secure
Least-privilege permissions
- Restrict data access: Configure TinyBase to only store non-sensitive information (like UI preferences). Never store passwords, API keys, or authentication tokens in it.
- Limit agent capabilities: If integrating with an AI agent, ensure the agent can only read/write specific data tables it needs—not all stored information.
- Isolate credentials separately: Keep secrets in a dedicated secure vault (like AWS Secrets Manager or HashiCorp Vault), completely separate from TinyBase storage.
Network isolation
- Encrypt data in transit: Require encrypted connections (TLS/HTTPS) when TinyBase syncs data between systems; verify this setting is enabled in configuration.
- Encrypt data at rest: Enable encryption for stored files on disk; confirm this feature is active if handling any moderately sensitive business data.
- Segment the network: Run TinyBase on isolated internal networks where only authorized systems can connect; avoid exposing it to the public internet.
Monitoring
- Track data access logs: Enable logging to see who accesses TinyBase and when; review logs weekly for unauthorized or unusual activity.
- Alert on sync failures: Set up notifications if data synchronization breaks—could indicate tampering or system compromise.
- Audit configuration changes: Monitor and log any modifications to TinyBase settings, permissions, or stored data structure.
Red flags to watch for
- Project abandonment: Check the TinyBase GitHub repository monthly for signs of inactivity (no updates in 6+ months, unanswered security issues); consider switching if maintenance stops.
- Unvetted dependencies: Review what other software packages TinyBase depends on; avoid using it if those dependencies are also unmaintained or unknown.
- Logs containing secrets: Before deploying, search system logs and error messages to confirm they never display API keys, tokens, or agent prompts.
Alternatives
- PouchDB — mature peer-to-peer sync database with stronger adoption and security track record
- Replicache — purpose-built for sync engines with explicit focus on consistency guarantees
- Yjs — CRDT-based collaboration library with broader production usage and community security reviews
- Redux or Zustand — simpler state management if real-time sync isn't required
