Pricing

The full catalogue, globe, compare tool, and JSON API are open source (MIT) and free to use — self-host or use the public site. An optional one-off supporter payment helps fund ongoing work; it is not a paywall. No subscription.

Supporter

£20 one-time

A voluntary £20 one-time payment to support ongoing development of Cachesphere — docs, globe, compare, and the agent-friendly JSON catalogue. All core features stay free; you get the same software as self-host.

  • Supports maintenance and richer flagship language pages
  • One-off payment — no recurring charge
  • Stripe receipt by email
  • We may add optional extras later (for example saved comparisons or personal API keys for supporters) — nothing specific is promised yet

Optional support, not a paywall. Everything in the open catalogue stays available without paying; the supporter tier is simply a way to say thanks and help keep the project going if you want to.

Card payments are processed securely by Stripe. We do not see or store your full card number. After payment, Stripe emails a receipt. This is a one-time supporter payment — it does not unlock a separate paid product today; see Terms for how charges are described.
