Why buy rather than rent

Own the asset

Website builders rent you a page and keep the code. You get the whole system and its repository.

Subscription page builders

  • Monthly fee forever
  • Source code stays with the vendor
  • Features gated behind higher tiers
  • Migration means a rebuild

Cayanide Labs

  • One-time licence, yours to keep
  • Full source code on delivery
  • Every feature in every tier
  • Host it anywhere you like
Also from Cayanide

Private storage, built to order

Custom NAS hardware for teams that would rather own their storage than rent it by the gigabyte.

Total ownership

No vendor lock-in. Your files, your permissions, your roadmap.

Local-speed access

Stream, edit and back up over your own network without cloud round-trips.

Built to grow

Add drives, memory and services as your storage demand increases.
