Problem

Building collaborative applications requires developers to manage complex real-time synchronization, stateful backend infrastructure, and secure code execution environments, which are difficult to orchestrate and scale. Existing solutions often lack integrated tooling for both real-time data sync and AI-centric workloads, forcing teams to stitch together multiple services.

Solution

Jamsocket provides a backend platform for building sync engines that power collaborative and AI-centric applications. The platform consists of multiple open-source products: Plane, an orchestrator that manages real-time backends; Y-Sweet, a document store and realtime sync backend; and ForeverVM, stateful Python REPLs as a service for AI code execution. Together, these tools let developers deploy real-time backends and code sandboxes from a single platform, simplifying the infrastructure needed for collaborative apps. The Jamsocket team is joining Modal, and the products will continue to operate while core functionality is migrated to Modal's platform, allowing customers to deploy GPU inference, code sandboxes, and real-time backends all from one place.

Target Audience

Primary users are developers building collaborative applications and AI-centric products who need real-time sync, stateful backend orchestration, and secure code execution infrastructure.
