Show HN: SpaceApp – Self-hosted workspace running AI coding CLIs in parallel

SpaceApp is an MIT-licensed, self-hosted workspace that runs up to 16 AI coding CLIs (including OpenCode, OpenAI Codex, Claude Code, Gemini, Qwen, Kimi, Grok and DeepSeek) side by side in persistent rooms on your own machine, installed with a single npx command on Linux, macOS or Windows 11. It adds a coordinating agent called Nous, optional copilots and studios, a Vault for logins, and a Space Gateway that uses your subscriptions before API keys. The post notes that rooms are not a security boundary between mutually untrusted users and links to a Known Limitations page.
