Work with your favorite stack
Query JSON documents with Python, Ruby, Node.js or dozens of other languages. Build modern apps using your favorite web framework, paired with realtime technologies like Socket.io or SignalR.
The open-source database for the realtime web
RethinkDB pushes JSON to your apps in realtime.
When your app polls for data, it becomes slow, unscalable, and cumbersome to maintain.
RethinkDB is the open-source, scalable database that makes building realtime apps dramatically easier.

Building realtime apps just got easy
-
Reactive web and mobile apps
Web apps like Google Docs, Trello, and Quora pioneered the realtime experience on the web. With RethinkDB, you can build amazing realtime apps with dramatically less engineering effort.
-
Multiplayer games
When a player takes an action in a multiplayer game, every other player in the game needs to see the change in realtime. RethinkDB dramatically simplifies the data infrastructure for low latency, high throughput realtime interactions.
-
Realtime marketplaces
RethinkDB dramatically reduces the complexity of building realtime trading and optimization engines. Publish realtime updates to thousands of clients, and provide pricing updates to users in milliseconds.
-
Streaming analytics
Build realtime dashboards with RethinkDB data push notifications, and make instantaneous business decisions.
-
Connected devices
RethinkDB dramatically simplifies modern IoT infrastructures. Stream data between connected devices, enable messaging and signaling, and trigger actions in millions of devices in milliseconds.
What's in the box?
Robust architecture
RethinkDB integrates the latest advances in database technology. It has a modern distributed architecture, a highly-optimized buffer cache, and a state-of-the-art storage engine. All of these components work together to create a robust, scalable, high-performance database.
Everything you need to build modern apps
Express relationships using joins, build location-aware apps, or store multimedia and time-series data. Do analytics with aggregation and map/reduce, and speed up your apps using flexible indexing.
Built with love by the open source community
Originally developed by a core team of database experts and over 100 contributors from around the world, RethinkDB is shaped by developers like you participating in an open source community development process.
Scale your cluster in seconds
When you're ready to scale your app, shard and replicate in a few clicks using an intuitive web UI.
If you need it, a simple API provides precise control over the cluster:
r.table('games').reconfigure(shards=5, replicas=3)Monitor your production cluster with live statistics and complete visibility into running jobs:
r.db('rethinkdb').table('jobs').changes()
