Supports parallel task execution in dedicated sandboxes.

Detailed Introduction

Open SWE is an open-source framework designed to empower engineering organizations to develop their own sophisticated internal AI coding agents. Inspired by the successful patterns of companies like Stripe and Ramp, it provides a robust architecture built on LangGraph and Deep Agents. The framework features isolated cloud sandboxes for secure code execution, a curated set of development tools, and intelligent context engineering. It aims to streamline development workflows by automating tasks, integrating with existing systems like Slack and Linear, and facilitating automatic PR creation, all with minimal human oversight.
