Open SWE: An Open-Source Framework for Internal Coding Agents

Over the past year, several engineering organizations, including Stripe, Ramp, and Coinbase, have developed internal coding agents to assist their development teams, integrating them into existing workflows through platforms like Slack, Linear, and GitHub. These agents share common architectural patterns, such as isolated cloud sandboxes, curated toolsets, subagent orchestration, and rich context integration, which ensure effective deployment in production environments. Open SWE, an open-source framework, captures these patterns and provides a customizable foundation built on Deep Agents and LangGraph, offering core architectural components seen across these implementations. The framework supports isolated execution environments, a curated toolset, context engineering, and subagent orchestration, allowing organizations to adapt the system to their specific needs. Open SWE serves as a starting point for teams exploring internal coding agents, providing flexibility through pluggable components, middleware for reliable orchestration, and options to customize sandbox providers, models, tools, triggers, and validation processes, while maintaining an upgrade path through continuous improvements to Deep Agents.
