Proprietary(closed SaaS IDE, no public source)

model

multi-provider (OpenAI/Anthropic/Gemini/xAI) but the product is proprietary

source

closed(cursor/cursor holds only .github, README.md and SECURITY.md

Fully proprietary commercial product with no open source license and no public source. A direct read of the repo and the terms settles it: the GitHub contents API shows cursor/cursor holds exactly three entries (.github, README.md and SECURITY.md), the repo API reports no license and no language, and the Terms of Service state that Anysphere and its licensors retain all right, title and interest in the Service and reserve all rights not granted. None of the editor runtime is published, so there is no public core for a gating question to apply to.
