Backends for
The platform for scaling sync engines, based on the infra behind Figma and Google Docs.

How it works
Run your sync engine.
1
Spawn a backend
When a user opens a document in your app, your app spins up a sync server on Jamsocket.
2
Connect clients
Clients connect directly to the sync server over WebSocket or HTTP.
3
Your code runs
Each sync server is an isolated Linux process, running code you provide in any language.
4
Automatic termination
Once every client of a sync server disconnects, we automatically suspend it until they reconnect.

Case Studies
Jamsocket in Action
Jamsocket is the most powerful solution for realtime collaboration, AI agents, and data-intensive apps.
Rayon
Multiplayer Collaboration
Rayon uses Jamsocket as the realtime data backend for its CAD software.
When a user opens a document, Rayon spins up a Jamsocket backend, which serves as the source-of-truth for all clients connected to that document. The session backend is responsible for persisting changes to the database.
“We love using Jamsocket at Rayon. It just works!”
Bastien Dolla
Co-founder, Rayon
Op
Data Intensive Apps
Op lets users analyze data with Pandas within the browser.
When a user opens a sheet, Op spins up a Jamsocket backend to load the user’s dataset into memory. It then allows the user to answer questions about the dataset using plain language (by invoking an LLM) or directly in Python.
“I wanted the easiest way to set up a code execution backend for every user. Jamsocket had the simplest API.”
Samuel Quinn
Co-founder, Op
Toolchest
Jupyter Notebooks
Toolchest uses Jamsocket to create ephemeral demo notebooks for its computational biology platform.
When prospective customers click the link, Toolchest starts a Jupyter server inside a Jamsocket session backend. When the tab is closed, we shut the notebook down.
“Before Jamsocket, we set up demo environments manually for each lead. Now, setting up a demo environment is as easy as sharing a link.”
Noah Lobovic
Co-founder, Toolchest
Advanced concepts
Building blocks for modern apps
Jamsocket provides simple, powerful abstractions for locking and authorization.
Keys
Ensure that only one session backend is running per document at a time, as a single source of truth.
Tokens
Limit backend access to authorized people by gating that backend behind a tokenized URL.
Monitor your app
Observability built in
Retrieve application logs or view details like memory and CPU usage in your Jamsocket dashboard or CLI.
