Frequently asked questions

Is the protocol really free?
Yes. The SIG protocol specification, all Rust crates, and the CLI are fully open source under the MIT license. You can self-host everything at no cost, forever.
What does the managed service include?
Pro and Enterprise plans host your .well-known endpoints, manage key rotation, provide a dashboard for managing attestations, and include monitoring and analytics.
Can I migrate between self-hosted and managed?
Absolutely. Everything is based on the open SIG protocol, so your event logs and keys are fully portable. Export or import at any time — no vendor lock-in.
Do you offer annual billing?
Yes — annual plans come with two months free. Contact us for Enterprise annual agreements.
What happens to my data if I cancel?
Your event logs and keys are always exportable. After cancellation, you have 30 days to export everything. The protocol is portable — switch to self-hosting at any time.
