QCoder
What QCoder is
QCoder is a free, standalone AI code editor based on a fork of Visual Studio Code. It runs on Linux, macOS, and Windows, with code completion, code chat, and an agent mode for multi-step work. You can provide keys for OpenAI, Anthropic, Google, DeepSeek, Mistral, Groq, and xAI, or connect local models through Ollama or LM Studio without an API key. Inline suggestions appear as red and green diffs that you can accept or reject by hunk. Agent mode can read and write files, run terminal commands, and produce reviewable diffs. MCP connections can link databases, APIs, documentation, and custom tools over stdio or HTTP. QCoder says it supports air-gapped use, optional Docker sandboxing, and OS-keychain key storage. It also says data is not sent to its servers by default and code remains local unless sent to an API you control. The MIT-licensed project offers a self-hosted option.
