Managed CDN for sites that need Tor and clearnet delivery, without rolling your own hidden service.
ViaductCDN is a managed CDN for sites that want to be reachable over Tor — without standing up and operating their own hidden services.
Every tenant site gets its own per-site .onion address, auto-provisioned within ~60 seconds of creation, plus an optional clearnet hostname. The same content is served over both, with consistent caching and a "no-JS first" delivery path that works on Tor Browser's "Safest" security level.
What you get
- Per-site .onion auto-published by our multi-tenant Tor pod — no key management, no descriptor publishing, no torrc edits.
- Optional clearnet with managed TLS via Let's Encrypt (Pro and Business plans).
- Edge caching (Varnish) with `vsthrottle` rate limiting and header sanitisation that strips `Server`, `Via`, and `X-Ms-*` from responses.
- Signed URLs for token-gated content with automatic SAS rotation on Azure Blob origins.
- Progressive MP4 delivery for video, with a noscript fallback page for Tor users with JavaScript disabled.
- Per-tenant abuse triage and operator-mediated suspension / reinstate flows.
Why not Cloudflare Onion Routing?
Cloudflare ships an .onion for sites already on its CDN, anchored to your Cloudflare-managed identity. ViaductCDN inverts the model: the customer's `.onion` is the site's identity, the clearnet hostname is optional, and there is no master .onion fronting tenant traffic. Useful when your audience uses Tor as the primary surface, not as a fallback.
How it's billed
- Pro: $39/month with 250 GB included egress, $0.06/GB over.
- Business: $499/month with **5 TB** included egress, $0.04/GB over.
- A free anonymous tier is available outside the Marketplace (sign up directly at portal.viaductcdn.com/signup-anon) for .onion-only sites with no clearnet and a hard egress cap.
