Hugging Face Spaces: Hosted Platform for AI Apps, Demos, and Agent Tools
Hugging Face Spaces is a hosted platform to build, deploy, and share AI apps in the browser. It doubles as a public directory for models, apps, and agent tools, offering one-click forking and Git-based deployments. Teams can ship with familiar stacks like Gradio or Streamlit, or containerize with Docker, then run on free CPU or scale up to on‑demand GPUs. Ideal for demos, internal tools, and agentic workflows.
Explore the [Spaces hub](https://huggingface.co/spaces) and read the [Spaces overview](https://huggingface.co/docs/hub/en/spaces-overview).Configure deployments via the [Spaces config reference](https://huggingface.co/docs/hub/en/spaces-config-reference).Embed apps anywhere with [Spaces embed](https://huggingface.co/docs/hub/en/spaces-embed).Why Teams Choose Spaces
**Fast, repeatable shipping**: Push to a Space repo and the platform builds and serves your app. Scale hardware from a dropdown.**Familiar stacks**: Build with Gradio or Streamlit, serve static apps, or bring any framework via Docker (FastAPI works via Docker).**Integrated secrets and config**: Manage app secrets and YAML-based configuration for SDK, hardware, ports, and env.**Git-native CI/CD**: Sync with GitHub and automate using [CircleCI workflows](https://huggingface.co/docs/hub/en/spaces-circleci).**Embeddable and shareable**: Drop an iframe or script to let users interact without setup using [Spaces embed](https://huggingface.co/docs/hub/en/spaces-embed).**Agentic by design**: Expose Spaces as agent tools, integrate with HF Agents and MCP-compatible assistants. See [Agents on the Hub](https://huggingface.co/docs/hub/en/agents) and the guide on [Gradio Spaces as agent tools](https://huggingface.co/blog/burtenshaw/gradio-spaces-agent-tools).How It Works
1. Create a Space from the [Spaces hub](https://huggingface.co/spaces).
2. Choose a stack: Gradio, Streamlit, Static, or Docker (bring your own runtime).
3. Configure via YAML in README (SDK, hardware, secrets, ports) using the [config reference](https://huggingface.co/docs/hub/en/spaces-config-reference).
4. Push code; the app builds on commit and deploys automatically.
5. Scale hardware or switch to GPUs on demand via the UI or config.
6. Embed your Space or expose it for agent tool usage.
Key platform features:
Public or private SpacesFree CPU; paid CPU/GPU tiers with hourly pricing on the [HF pricing page](https://huggingface.co/pricing)Optional persistent storage add‑ons (verify in-account pricing)ZeroGPU for serverless-style sessions, included for hosting your own ZeroGPU Spaces on [HF Pro](https://huggingface.co/pro)Agentic Workflows and Tools
Spaces integrates with agent frameworks and MCP‑compatible assistants, so hosted apps can be invoked as tools within assistants or workflows.
