Durable Objects

Persistent data for each user, room, or job in your application.

API guide

One object. One place for its data.

An object is a small, persistent database with a name you choose, like user:alice. Store its JSON, run SQLite transactions, or keep small files together. Your application reads and updates it over an API.

A namespace groups one app’s objects, API keys, and spending cap.

Your application
my-app namespace
  • user:alice
  • room:general
  • job:42
Each object keeps its own data.

How charges and limits work

Every command, including reads and failed SQL, saves a recovery checkpoint. Charges use the full checkpoint size. Repeating the same request ID does not charge twice. Object deletion is free.

Up to 100 objects per namespace, 16 MiB per object, and 64 KiB per request or result. Retained recovery data counts toward a 10 GiB namespace allowance and is not reclaimed by object deletion. This service stores data; it does not run your application code.
