| License | The project states that its open-source engine is released under the MIT license. | The project metadata identifies the license as MIT. |
| Purpose | JayDB provides per-user sign-in and a JSON document database so static apps can work without an app-owned backend. | TinyDB is a lightweight, document-oriented database intended for small apps that would be poorly served by a SQL database or external database server. |
| Storage | The documentation says the engine uses AWS S3 or S3-compatible storage such as Cloudflare R2, MinIO, or Wasabi for durability. | By default, TinyDB stores data on disk in JSON format. |

In their own words
JayDB
JayDB is a JSON document database with per-user sign-in, aimed at static apps that need user, session, or tenant data without an app-owned backend. Documents are JSON at slash-separated paths, and the first write creates the namespace. Its REST data plane supports GET, PUT, DELETE, and prefix listing. Browser apps can authenticate through OIDC with Authorization Code and PKCE without embedding a client secret. Listed identity providers include Google, GitHub, Microsoft, generic OIDC, and custom OAuth2. The official SDK supports authentication, token refresh, typed document access, and compare-and-swap operations. ETag-based compare-and-swap may reject a write with HTTP 412 if the document changed since it was read. JayDB is available as managed cloud software or as a self-hosted Go engine under the MIT license, using S3-compatible storage or local disk. The free plan is free and includes 1 GB stored, 100,000 reads per month, and 10,000 writes per month; usage hard-stops at those allowances. Metered rates are $0.05 per GB-month of storage, $0.20 per million reads, and $0.50 per million writes.
