Supporter

£20 one-time

A single payment to support Cachesphere — documentation, the globe, and the agent-friendly JSON catalogue. Same software as self-host; this is gratitude, not a paywall.

  • One-off payment — no recurring charge
  • Stripe receipt by email
  • Helps fund ongoing improvements
  • Hosted API and team tiers may follow — we’ll keep supporters posted

After payment, Stripe emails a receipt. This is a one-time supporter payment — it does not yet unlock a separate hosted product; see Terms for how charges are described.
