| API | The data plane uses standard REST HTTP and supports GET, PUT, DELETE, and prefix listing. | The public ReQL API includes commands such as connect, run, table, joins, reconfigure and HTTP access. |
| Authentication | Each tenant exposes an OIDC issuer and supports Authorization Code with PKCE, so browser clients do not need embedded secrets. | Users and permissions are supported, but passwords are sent in plaintext unless TLS is enabled. |
| Durability | Durable data is kept in AWS S3 or compatible object storage such as Cloudflare R2, MinIO or Wasabi. | The FAQ says writes are not acknowledged until safely committed to disk by default. |
| License | The project states that its open-source engine is released under the MIT license. | The Linux Foundation licenses RethinkDB under the permissive Apache License 2.0. |
| Limit: transactions | The product page says writes cannot be made atomically across multiple documents. | G2 reviewers report that the lack of atomic updates across multiple documents led some teams to move to PostgreSQL. |
| Self-hosting | JayDB says its Go engine can be self-hosted as an embedded library or standalone server using S3-compatible or local storage. | RethinkDB is distributed as installable server software and an official Docker image, allowing users to operate their own clusters. |

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.
