Spaces
Hugging FaceManaged sandbox platform for hosting interactive ML apps, supports Gradio, Streamlit, Docker, and static SDKs with a free CPU tier, paid CPU/GPU upgrades, and a ZeroGPU shared-pool tier. Differentiates through tight integration with the Hugging Face Hub (one-click deploy from any model card) and community discoverability, making it the default demo surface for nearly every open-weight model release. ~400K+ apps as of early 2026 with reportedly ~40K new Spaces created per month and 100M+ monthly visits; the canonical 'where you go to try an open model in your browser'.
Hugging Face Spaces, managed hosting/runtime for ML demo apps via Gradio, Streamlit, Docker (arbitrary Dockerfile), or static HTML, with CPU/GPU hardware tiers. Confirmed live June 2026 via huggingface.co and HF Hub docs. Proprietary managed platform built on OSS SDKs (Gradio is OSS); the Spaces hosting platform itself is closed.

Closed managed hosting service. Apps are built with OSS SDKs (Gradio etc.) that run anywhere, but Spaces itself - the managed host/orchestration - is proprietary and not self-hostable; those SDKs are separate products, not a Spaces open core. Reclassified from open_core (borderline).

Adoption
5 medium confidenceHugging Face homepage (primary): Spaces hosts 1M+ AI applications, on a platform used by 50,000+ organizations. 1M+ hosted apps plus the broad end-user traffic to those demos puts served reach into the >10M band. Headline (1M+ Spaces) cites HF's own homepage; per-Space user totals not individually disclosed so confidence medium.

Spaces = 1M+ AI applications hosted; 50,000+ organizations on Hugging Face
Capability
3 medium confidenceExcellent for hosting/demoing ML apps with broad SDK and GPU support, but it is an app-hosting platform rather than a hardened arbitrary-untrusted-code sandbox (container, not microVM isolation), and free Spaces sleep. Mid-tier within the deployment sandbox lens.
