Questions

Is the core really free?

Yes. Nauro is open source. You install it with uv tool install nauro and run it on your own machine with unlimited local use and projects.

What does hosted access include?

Cloud sync and remote MCP access for a single owner are included within 5,000 calls/month. Running Nauro locally does not count against that allowance.

What happens if I hit the 5,000-call limit?

Hosted calls pause until the first of the next month (UTC); your local store and local MCP server keep working throughout. Your agent gets a clear in-session message with the reset date rather than an opaque failure, and warnings with the remaining count appear inside the last 500 calls. Higher limits are a conversation, not a checkout: [email protected]. Details on the plans page.

Does my code or data leave my machine?

The local store and retrieval path make zero external calls. When you enable cloud sync, the decisions, state, and open questions you choose to sync are stored in the hosted store so they can be read across surfaces. Nauro never uploads your source files, though anything you write into a decision's own text is part of that decision. Deleting synced data is currently via support request. Nauro sends no product analytics.

Can several people share one hosted project?

No. A hosted project currently has one owner and no invite or shared-membership mechanism. Cloud sync lets that owner use the same record across their machines and connected surfaces.

Team support is a planned expansion once teams show clear demand. The intended direction is one trusted project record shared by multiple engineers and their agents, with clear membership and ownership, controls over who can propose or approve changes, a visible approval history, conflict handling, and safe concurrent writes. The team trust model, workflow, pricing, and timing are not decided yet. If your team needs shared projects, tell us; those conversations will shape the design.

Start with a local decision record.

Install the open-source core in one command and run it on your machine. Cloud sync and remote MCP access are included up to 5,000 calls/month. Contact support if you need a higher hosted limit.
