Open Source Alternatives to Cursor

Switching from Cursor to an open source alternative means giving up its custom VS Code fork in favor of a tool that layers onto an editor or terminal you already use, without a closed source application layer in between. Cline runs as a VS Code or JetBrains extension with the same approval-driven, multi-file agent workflow Cursor offers, while Aider provides a terminal-native, git-aware alternative for developers who don’t want an IDE dependency at all. OpenHands goes further with sandboxed autonomous execution for larger tasks. If it’s specifically Cursor’s Tab-style inline completions you rely on rather than its agentic chat, Tabby is a more targeted match — a self-hosted completion server you run on your own GPU, with no agentic file-editing loop involved. All four support Claude, GPT, Gemini, and local models through Ollama, so you’re not limited to a single vendor’s model lineup or usage-based pricing.
