SWEKit

An open-source, framework-agnostic toolkit for building highly customizable AI-powered Software Engineering (SWE) agents.

SWE-Kit (by Composio) is a headless IDE and AI-native toolset designed for creating dependable, custom coding agents. It is framework-agnostic, supporting major frameworks like LangChain and LlamaIndex, and integrates specialized tools: Code Analysis, File Management, and Git tools. The platform runs agents securely in isolated Docker environments (also supporting cloud options like E2B). Developers use it to automate complex workflows, including GitHub PR reviews, codebase Q&A, and bug resolution. Notably, a reference agent built with SWE-Kit scored 48.60% on the SWE-bench Verified track, validating its performance on real-world software issues.
