OpenSpaces: An Author-Claimed Open-Source, Self-Hostable Clone of ChatGPT Spaces You Can Run Yourself

Developer Anil Chandra Naidu Matcha (@matchaman11) published OpenSpaces, an open-source self-hosted workspace modeled on OpenAI's ChatGPT Spaces, in an X post on October 8, 2026 (KST), linking the repository at https://github.com/Anil-matcha/open-spaces.

OpenSpaces is a community-built alternative that appeared shortly after OpenAI's Spaces announcement. According to the author's own stated scope, it offers in-page AI writing, inline image generation, 53 models with any-provider support, and is free, open-source, and self-hosted. Its license, install steps, and self-hosting requirements remain unverified at draft time because the repository body was not fetched, and numerical claims are treated only as author claims or third-party aggregator citations.

What OpenSpaces Is and Who It Serves

OpenSpaces aims to reproduce the "shared document plus AI working space" idea of ChatGPT Spaces in a form you can run yourself. The backdrop: per OpenAI's official Spaces page, ChatGPT Spaces is a collaborative space where teammates build living documents alongside ChatGPT, Codex, and personal AI agents (dots) on shared context. Per Engadget's reporting, it was announced at DevDay on September 29, 2026 alongside Pages and Dots, rolling out first to Pro, Business, and Enterprise plans on the ChatGPT desktop app and web.

OpenSpaces may suit individual developers who want to try a document-style AI workspace before paying for a collaboration hub, self-hosters who want an AI workspace on their own server, and makers who want to test in-page AI writing plus inline image generation in one screen. Teams expecting official-Spaces-grade real-time collaboration, permissions, and connected-tool depth should treat this as an experimental alternative, not a drop-in replacement.

Author-Stated Features and the Direct Run Path

The author's original post (@matchaman11) states exactly four features, and nothing beyond them is treated as confirmed:

  • Write with AI inside your pages
  • Generate images inline
  • 53 models, any provider (author's wording, verbatim)
  • Free, open-source, self-hosted

The only confirmed run path is the GitHub repository the author linked: https://github.com/Anil-matcha/open-spaces. Install commands, supported clients, license, and compatibility details are omitted until the repository source itself is checked.

Why It Matters Now, and the Verified Limits

The timing is the signal: roughly one week after OpenAI announced Spaces and Pages, the community shipped a "version you can run yourself," showing real demand for document-style AI workspaces. A third-party roundup (AGI Hunt, 2026-10-07) reports the project received about 3.4k stars, is built on Next.js, FastAPI, and Supabase, and advertises 53 multimodal models via MuAPI. That is cited strictly as a secondary source, not an independently verified fact.

The verified limits are equally clear. Figures such as 53 models, any-provider, and the star count must be used only as author claims or aggregator citations, and the license, install procedure, and self-hosting requirements are unverified. An unrelated reply alleging star-count inflation is an unverified claim and is not covered in this article. Always check the repository's README and license directly before running it.
