The editor runs multiple AI agents in parallel, including Codex and GitHub Copilot, and connects to vendor APIs such as DeepSeek. Against Cursor under the same conditions, GENSHI AI measures about 96 percent lower memory use at idle and about 88 percent lower while an agent runs.","whyItMatters":"A small medical AI company now builds its own development tool to run many agents at once, and the measured memory gap against Cursor is the argument it is publishing alongside the source code.","webCardHtml":"\u003cp\u003eNagashima began writing necoder in July 2026, released a first version in August, and moved off Cursor entirely in September. In-house engineers now use it for daily work. The editor is built on the Agent Client Protocol, so existing agent subscriptions carry over and no separate necoder API key is needed. Templates cover DeepSeek, GLM, Kimi, Qwen, MiniMax, Xiaomi MiMo, OpenRouter, and Ollama, and any OpenAI- or Anthropic-compatible API can be added.\u003c/p\u003e\u003cp\u003eThe problem it addresses is window sprawl.
