description: Sigstore is a free, open-source software-supply-chain signing service operated as a public-good,
  non-profit by the Open Source Security Foundation (OpenSSF) under the Linux Foundation. There is
  no paid tier, no commercial SKU, and no per-call charge for the public Sigstore instances (Fulcio,
  Rekor, the public-good Cosign workflow). Organizations that need private/dedicated infrastructure
  typically self-host or use a vendor-operated Sigstore service.
