Self-Hosted AI Code Review Tools

ripwire helps AI coding agents find relevant code and assess changes without filling their context with whole files. It runs offline on your machine as a self-contained binary, with a CLI and an optional MCP server. It's for developers who want their agents to spend less context on repository research and check the effects of their edits.

Superpowers adds a structured development process to AI coding assistants. It's for developers who want their agent to agree on a design before writing code, follow an implementation plan, and check its work against that plan. The open-source framework uses the MIT license and works inside coding tools including Claude Code, Codex, Cursor, Gemini CLI and OpenCode.

Codex CLI is an open source coding assistant that runs on your computer and works with local repositories. It's for developers who want to explore code, make changes, and use their existing development tools from the terminal. It runs on macOS, Windows, and Linux under the Apache 2.0 license.

Twinny is an AI coding assistant for VS Code that lets developers choose where their models run: on their own computer, a private server or a hosted API. It's for individuals and teams who want code suggestions and repository chat with control over where their code goes. The extension and team gateway are open source under the MIT license.

Kodus is an AI code review tool for engineering teams that want automated pull request feedback while choosing where the reviewer runs and which model it uses. Its open source core uses the AGPL license and can be self-hosted with Docker Compose or on Kubernetes. Kodus also offers a hosted cloud service that manages the infrastructure.

ECC is a free, MIT-licensed open source toolkit that adds repeatable engineering workflows to coding assistants. It runs alongside your chosen agent and works with self-hosted models or cloud providers through that agent's supported endpoints. It's for developers who want planning, testing and review to follow a consistent process across coding sessions.

Skills (mattpocock) is an MIT-licensed collection of engineering workflows for developers using Claude Code, Codex and other AI coding agents. Its small, separate skills work with any model and can be combined or adapted to your project, so you can choose specific practices without adopting an entire development process.

PR-Agent is an open source AI code review agent for development teams that want to choose where their reviewer runs and which model it uses. It reviews pull requests, writes descriptions, suggests code improvements, and answers questions about proposed changes. You can run it locally through a CLI, on a self-hosted server, in Docker, or through GitHub Actions.

Agenta is an MIT-licensed, open source workspace for teams that want AI agents to handle tasks in chat and continue recurring work in the background. You can self-host it with Docker Compose or Helm to keep agents and workspace data on your infrastructure, or use Agenta Cloud as a hosted service.

codecompanion.nvim brings model chat, inline code edits, and coding agents into Neovim. It's for developers who want AI assistance inside their editor, with a choice between local LLMs through Ollama and cloud providers such as Anthropic, OpenAI, and Google Gemini. The plugin runs in Neovim; where model processing happens depends on the backend you connect.

OpenHands is a coding agent platform for developers and teams that want agents to make changes across a codebase and handle recurring engineering work. You can run it on your own computer or self-host it on a server. Its core is open source under the MIT license, and a separate OpenHands Cloud service offers hosted execution.

Kilo Code is an AI coding agent for developers who want help writing and understanding code in their editor or terminal. It runs in VS Code, JetBrains IDEs and the CLI, with cloud agents available for remote work. The project is open source under the MIT license and can be self-hosted.
