Show HN: Hosted JayBase – An append-only data store for safe AI agent writes
Hosted JayBase is an append-only data store designed to allow AI agents safe write access to company data. It maintains an attributed history where every action is recorded as a new event, ensuring that corrections do not overwrite previous entries. The service includes a built-in user interface for inspecting agent activities and supports use cases like bookkeeping, inventory management, and job tracking.
- ▪JayBase uses an append-only architecture to preserve a complete history of all agent writes.
- ▪The platform provides a built-in UI that allows users to browse and verify data modifications made by AI agents.
- ▪Corrections to agent errors are handled by adding new events rather than deleting or altering existing records.
- ▪The service is priced at $20 per month for each JayBase instance.
- ▪Typical applications include managing ledger entries, customer profiles, stock counts, and job status updates.
