The setup provides 16GB RAM, 2 vCPU, 50GB disk, and unlimited Spaces on HuggingFace, plus 100K daily requests and global CDN via Cloudflare—dwarfing the 512MB free tiers of Railway and Render. A critical Cloudflare Worker script converts HEAD requests to GET to avoid HuggingFace Spaces' 405 errors, enabling free uptime monitoring that also prevents the 48-hour inactivity sleep.", "body_md": "Every \"deploy your AI app\" tutorial sends you to Railway, Render, or Vercel.\n\nI needed something different. My app runs:\n\nNone of these work on serverless platforms.\n\nAfter research and testing, I landed on:\n\n**HuggingFace Spaces (free) + Cloudflare Worker (free) + Custom domain (~$10/year)**\n\nHere's why this combination is unbeatable for AI apps.\n\n| Resource | Free Allocation |\n|---|---|\n| RAM | 16GB |\n| CPU | 2 vCPU |\n| Disk | 50GB |\n| Spaces | Unlimited |\n| Sleep | After 48hrs inactivity |\n\nFull Docker support — any framework, any language. FastAPI, SSE streaming,\n\nlong-running processes — all work perfectly. Compare this to Railway (512MB)\n\nor Render (512MB) on free tier.\n\n| Feature | Free Allocation |\n|---|---|\n| Worker requests | 100K/day |\n| Bandwidth | Unlimited |\n| SSL certificates | Auto, free |\n| CDN locations | 300+ globally |\n| Domains | Unlimited |\n\nUser → yourdomain.com (Cloudflare Worker)\n\n→ username-spacename.hf.space (HF Spaces)\n\n→ Docker container (your app)\n\n→ External APIs\n\nHuggingFace custom domains require Pro ($9/month).\n\nThe free URL `username-spacename.hf.space`\n\nis fine for testing but not\n\nfor a real product.\n\nThe fix? A Cloudflare Worker that proxies all traffic — free, instant, global.\n\n``` js\nexport default {\n  async fetch(request, env, ctx) {\n    const url = new URL(request.url);\n    const targetUrl = 'https://username-spacename.hf.space' \n                    + url.pathname + url.search;\n\n    // Convert HEAD to GET for HF Spaces compatibility\n    // Critical: monitoring tools (UptimeRobot etc) use HEAD requests\n    // HF Spaces returns 405 for HEAD — this fixes it\n    const method = request.method === 'HEAD' ? 'GET' : request.method;\n\n    const newRequest = new Request(targetUrl, {\n      method: method,\n      headers: request.headers,\n      body: request.method === 'HEAD' ? null : request.body,\n    });\n\n    const response = await fetch(newRequest);\n    const newHeaders = new Headers(response.headers);\n    newHeaders.set('Access-Control-Allow-Origin', '*');\n\n    return new Response(\n      request.method === 'HEAD' ? null : response.body,\n      {\n        status: response.status,\n        statusText: response.statusText,\n        headers: newHeaders,\n      }\n    );\n  },\n};\n```\n\n⚠️\n\nThe HEAD→GET conversion is not optional.Without it, UptimeRobot\n\nand other monitoring tools will report your site as DOWN even when it's\n\nperfectly healthy. HF Spaces only accepts GET requests on the root path.\n\nCreate a Space at huggingface.co/spaces/new — select **Docker** as SDK.\n\nYour `Dockerfile`\n\n:\n\n```\nFROM python:3.11-slim\nWORKDIR /app\nCOPY . .\nRUN pip install -r requirements.txt\nENV PORT=7860\nEXPOSE 7860\nCMD [\"python\", \"-m\", \"your_app\"]\n```\n\nPush your code:\n\n```\ngit remote add hf https://huggingface.co/spaces/username/spacename\ngit push hf main\n```\n\nAdd API keys in Space Settings → **Variables and Secrets**.\n\n`myapp-proxy`\n\n)In Cloudflare DNS, add:\n\n`@`\n\n`username-spacename.hf.space`\n\nAdd a free [UptimeRobot](https://uptimerobot.com/?rid=49c064d68c8652) monitor pointing to `https://yourdomain.com`\n\n.\n\nThe HEAD→GET Worker fix ensures monitoring shows green correctly.\n\nAs a bonus — UptimeRobot pings every 5 minutes keep HF Spaces awake,\n\npreventing the 48hr sleep entirely!\n\n| Service | Monthly Cost |\n|---|---|\n| HuggingFace Spaces | $0 |\n| Cloudflare DNS + Worker + SSL | $0 |\n| UptimeRobot monitoring | $0 |\n| Domain name | ~$0.83 |\nTotal |\n~$0.83/month |\n\nFor comparison:\n\nRailway, Render, and Vercel dominate tutorials because they have marketing\n\nbudgets. HuggingFace Spaces + Cloudflare is genuinely better for AI apps:\n\n✅ 16GB RAM vs 512MB on competitors\n\n✅ Full Docker support\n\n✅ No process killing or timeout limits\n\n✅ Global CDN via Cloudflare\n\n✅ Auto SSL\n\n✅ $0.83/month total\n\nThe only cost is your domain name. Everything else is free.\n\nI used this exact stack to deploy my own AI DevOps tool —\n\nfeel free to check it out at [deepshell.cloud](https://deepshell.cloud).\n\n*If this helped you, drop a ❤️ and follow for more DevOps + AI content.*", "url": "https://wpnews.pro/news/how-i-hosted-a-production-ai-app-for-10-year-huggingface-spaces-cloudflare", "canonical_source": "https://dev.to/muralipala/how-i-hosted-a-production-ai-app-for-10year-huggingface-spaces-cloudflare-worker-5gfk", "published_at": "2026-05-28 05:10:56+00:00", "updated_at": "2026-05-28 05:23:41.745866+00:00", "lang": "en", "topics": ["ai-infrastructure", "ai-tools", "ai-products", "ai-startups", "mlops"], "entities": ["HuggingFace", "Cloudflare", "Railway", "Render", "Vercel", "Docker", "FastAPI"], "alternates": {"html": "https://wpnews.pro/news/how-i-hosted-a-production-ai-app-for-10-year-huggingface-spaces-cloudflare", "markdown": "https://wpnews.pro/news/how-i-hosted-a-production-ai-app-for-10-year-huggingface-spaces-cloudflare.md", "text": "https://wpnews.pro/news/how-i-hosted-a-production-ai-app-for-10-year-huggingface-spaces-cloudflare.txt", "jsonld": "https://wpnews.pro/news/how-i-hosted-a-production-ai-app-for-10-year-huggingface-spaces-cloudflare.jsonld"}}
