Void – open-source Cursor alternative (voideditor.com)

Void is an open‑source, VS Code–based alternative to Cursor that lets you keep your themes, keybindings and settings with one click while routing LLM usage directly — not through a private backend. It supports both hosting private open‑source models (DeepSeek, Llama family, Qwen, etc.) and direct connections to commercial “frontier” models (Gemini 2.5, Claude 3.7, Grok 3, o4‑mini, Qwen 3), so you can run locally to avoid API credits or connect to a provider when needed. Core features include Agent Mode (full file create/edit/delete, terminal and MCP tool access), Gather Mode (read/search‑only), checkpoints for LLM changes, lint error detection, native tool use, and fast apply performance even on 1,000‑line files. For the AI/ML community this matters because it removes the middleman and lowers barriers to experimentation with private or open models while preserving developer ergonomics from VS Code. Crucially, Agent Mode can enable tool‑enabled, agentic workflows even for open models that don’t natively support tool calling, making local models more capable for code generation, repo manipulation, and automation. The tradeoffs to watch are governance and security (Agent Mode’s file/terminal access) and model management overhead, but Void is a practical step toward more private, flexible LLM integration for developers and researchers.
