JayBase's creator claims the newly hosted append-only, attributed datastore lets agents modify business records while preserving inspectable history and correction events, reducing the risk of silent destructive writes.

What is this?
JayBase is a hosted append-only fact store for AI agents working with critical business data, published from Kyle Visner’s GitHub account and announced via Show HN. It accepts flexible JSON facts while preventing the hosted API from rewriting prior entries; its creator describes writes as auditable, replayable, and reversible, with corrections retained as new events and a browsing interface for inspection. The supplied material establishes the release and its claimed semantics, but provides no independent validation of those safety claims or implementation details.
Why it matters to Scott
Scott’s “Keep the Bronze,” Cognitive Git, and Persistent delta event log pages already prescribe immutable source history, append-only changes, and correction events rather than destructive rewrites. JayBase is a concrete hosted instance of that established position, but the supplied evidence offers no independent validation or novel control that would change what Scott builds or argues.

You want agents doing real work on company data, not just generating insights. JayBase keeps an append-only, attributed history, so every write is saved and corrections are new events.

## Why write access can stay usable
A bad agent write can poison the data you trust if history disappears. Hosted JayBase is an append-only, attributed store with a built-in UI so you can browse what agents wrote.
Agents can work on sensitive data, and you can inspect their writes without digging through terminal logs. When a write goes wrong, you catch it in the UI and correct it as a new event. The past stays in the record.
## How JayBase actually works
Giving agents write access needs a store that keeps history. Here is a short look at how JayBase handles agent writes.
## What can you do with it?
Use JayBase as the place where agents write the company data behind real work.
1. ### Bookkeeping
Agents post ledger entries, bills, and payments into records your team can open and verify.
2. ### Storing customer data
Agents create and update customer profiles in one place you can browse and update directly.
3. ### Inventory
Agents adjust stock counts and item records as operations move, without scattering numbers across tools.
4. ### Job tracking
Agents log jobs, status updates, and notes you can track and update as the work progresses.
