Hosting & infrastructure

Question 1

Where are Blanca's Builder sites hosted?

Accepted Answer

On Cloudflare's global edge network with origin compute in Frankfurt and Stockholm. Static content is served from the location nearest the visitor.

Question 2

Is a CDN included?

Accepted Answer

Yes. Every project is served through Cloudflare's CDN with caching, image optimisation and Brotli compression enabled by default.

Question 3

What is the uptime SLA?

Accepted Answer

99.9% on Builder, 99.95% on Pro and 99.99% on Enterprise. Historical uptime is visible at /trust/uptime.

Question 4

How fast is my site for visitors abroad?

Accepted Answer

Static assets are served from the nearest of 300+ Cloudflare edge locations. Dynamic responses round-trip to the nearest origin region (Frankfurt or Stockholm).

Question 5

Will the hosting scale if my site goes viral?

Accepted Answer

Yes. The edge serves static traffic essentially without limit. Dynamic compute scales horizontally; Enterprise plans include reserved capacity for predictable spikes.

Question 6

How much storage is included?

Accepted Answer

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.

Question 7

Are there bandwidth limits?

Accepted Answer

No hard limits on Pro and Enterprise. Builder and below have generous monthly bandwidth allowances that fit the vast majority of projects.

Question 8

Is rate limiting available?

Accepted Answer

Yes. Per-route limits can be set in Settings, Security, Rate limits. The defaults block common abuse patterns without affecting normal users.

Question 9

Are sites protected against DDoS attacks?

Accepted Answer

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.

Question 10

Do my pages render on the server?

Accepted Answer

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.

Question 11

Which runtime does the server side use?

Accepted Answer

Cloudflare Workers with nodejs_compat. It is fast (V8 isolates, no cold starts) and resource-efficient — perfect for SSR and API routes.

Question 12

Can I run PHP, Python or Ruby on Blanca's Builder?

Accepted Answer

No. The runtime is JavaScript/TypeScript on Cloudflare Workers. You can call PHP or Python services running elsewhere via HTTP.

Question 13

Can I run background jobs and cron?

Accepted Answer

Yes. Use Cron Triggers in Cloudflare Workers, or pg_cron inside Supabase for database jobs. Both are documented in the Knowledge Center.

Question 14

Are WebSockets supported?

Accepted Answer

Yes, via Cloudflare's Durable Objects. They are the right tool for chat, live collaboration and real-time dashboards.

Question 15

How are file uploads handled?

Accepted Answer

Uploads go directly to Supabase Storage via signed URLs, so they never touch our compute. Limits depend on your Supabase plan.

Question 16

Is private/dedicated hosting available?

Accepted Answer

Yes, on Enterprise. We deploy a dedicated edge isolate, dedicated Supabase project and optional dedicated database region.

Question 17

Can I pin data residency to the EU?

Accepted Answer

Yes. EU residency is the default; Supabase data is stored in Frankfurt or Stockholm. US or Asia residency is configurable on Enterprise.

Question 18

Is monitoring included with hosting?

Accepted Answer

Yes. Request logs, error tracking and Core Web Vitals are collected automatically. Forward to Datadog, Sentry or your tool of choice in Settings, Observability.

Question 19

Do I get credits if you breach the SLA?

Accepted Answer

Yes. The SLA terms describe the credit schedule — 10% for missing 99.9%, scaling up to 100% credit for a major outage.

Question 20

Can I move my site off Blanca's Builder if I want to?

Accepted Answer

Yes. Project, Export produces a clean repository. You can self-host on any Node-compatible platform or another edge provider.
