Hosting & infrastructure
Where your project runs, how the edge is structured and what you can control.
- Where are Blanca's Builder sites hosted?On Cloudflare's global edge network with origin compute in Frankfurt and Stockholm. Static content is served from the location nearest the visitor.
- Is a CDN included?Yes. Every project is served through Cloudflare's CDN with caching, image optimisation and Brotli compression enabled by default.
- What is the uptime SLA?99.9% on Builder, 99.95% on Pro and 99.99% on Enterprise. Historical uptime is visible at /trust/uptime.
- How fast is my site for visitors abroad?Static assets are served from the nearest of 300+ Cloudflare edge locations. Dynamic responses round-trip to the nearest origin region (Frankfurt or Stockholm).
- Will the hosting scale if my site goes viral?Yes. The edge serves static traffic essentially without limit. Dynamic compute scales horizontally; Enterprise plans include reserved capacity for predictable spikes.
- How much storage is included?Starter 1 GB, Builder 10 GB, Pro 100 GB, Enterprise custom. Storage is for project assets and uploaded media; database storage is separate under Supabase.
- Are there bandwidth limits?No hard limits on Pro and Enterprise. Builder and below have generous monthly bandwidth allowances that fit the vast majority of projects.
- Is rate limiting available?Yes. Per-route limits can be set in Settings, Security, Rate limits. The defaults block common abuse patterns without affecting normal users.
- Are sites protected against DDoS attacks?Yes. Cloudflare's network-level DDoS protection is always on and free. Layer-7 mitigations are enabled by default; advanced WAF rules are configurable on Pro and Enterprise.
- Do my pages render on the server?Yes. Generated projects use TanStack Start with SSR for fast first paint and full SEO crawlability. Static-only pages are pre-rendered at build time.
- Which runtime does the server side use?Cloudflare Workers with nodejs_compat. It is fast (V8 isolates, no cold starts) and resource-efficient — perfect for SSR and API routes.
- Can I run PHP, Python or Ruby on Blanca's Builder?No. The runtime is JavaScript/TypeScript on Cloudflare Workers. You can call PHP or Python services running elsewhere via HTTP.
- Can I run background jobs and cron?Yes. Use Cron Triggers in Cloudflare Workers, or pg_cron inside Supabase for database jobs. Both are documented in the Knowledge Center.
- Are WebSockets supported?Yes, via Cloudflare's Durable Objects. They are the right tool for chat, live collaboration and real-time dashboards.
- How are file uploads handled?Uploads go directly to Supabase Storage via signed URLs, so they never touch our compute. Limits depend on your Supabase plan.
- Is private/dedicated hosting available?Yes, on Enterprise. We deploy a dedicated edge isolate, dedicated Supabase project and optional dedicated database region.
- Can I pin data residency to the EU?Yes. EU residency is the default; Supabase data is stored in Frankfurt or Stockholm. US or Asia residency is configurable on Enterprise.
- Is monitoring included with hosting?Yes. Request logs, error tracking and Core Web Vitals are collected automatically. Forward to Datadog, Sentry or your tool of choice in Settings, Observability.
- Do I get credits if you breach the SLA?Yes. The SLA terms describe the credit schedule — 10% for missing 99.9%, scaling up to 100% credit for a major outage.
- Can I move my site off Blanca's Builder if I want to?Yes. Project, Export produces a clean repository. You can self-host on any Node-compatible platform or another edge provider.
