Plan prices exclude VAT and sales tax. Stripe is the seller of record for plan payments: the tax due where you are is calculated and added at checkout, and your receipt, tax invoice and card statement (LINK.COM*) come from Stripe. Signet Stack Ltd provides the service.
✓ included · Add-on à-la-carte · Soon on the roadmap (not yet live). Every ✓ maps to a real server-enforced gate — inference modality, tier, or add-on — reconciled in lib/tier/capability-enforcement-map.ts.
Included in every plan
Platform-level trust & security that is always on — on Free as much as on Enterprise. Not a tier upsell; the substrate every Signetify site is built on.
Post-quantum signatures
Governance artifacts are signed with real FIPS-204 ML-DSA-65 — NIST post-quantum cryptography, live today, not a roadmap promise.
Published, verifiable keys
Every signature verifies against a versioned public key registry + a /.well-known endpoint, so any third party can check it independently.
Tamper-evident provenance
A BLAKE3 hash-chain records every asset transformation — an auditable history of exactly how each build was made.
Tenant isolation, evidenced
Scope is server-derived (VF-021); every cross-tenant access attempt is blocked and recorded, so 'zero leaks' ships with the evidence beside it.
Exactly-once payments
Payment webhooks are idempotent — a provider retry can never double-apply a charge or a subscription change.
EU AI Act Art.50 disclosures
AI-generated content carries a recorded, auditable synthetic-content disclosure — Art.50(2) evidence on tap.
C2PA Content Credentials
Exported and AI-generated assets carry C2PA Content Credentials — the open provenance standard — so any downstream tool can read exactly how each asset was made.
Commerce & growth — on every plan
The revenue engine ships with every plan: take payments, recover carts, and grow — no tier unlock required.
Multi-gateway payment rails
Stripe, Adyen, PayPal and Paystack — with Connect payouts and refunds — wired into every plan. Connect your processor to go live; live money activates at go-live.
Universal site ingestion
Turn any URL into a governed, editable Signetify build — SSRF-guarded, provenance-tracked from the first byte.
Verifiable receipts + verify badge
Every asset gets a public, independently-verifiable provenance receipt and a drop-in verify badge for your site.
Automated sales tax
Nexus-aware tax resolution — holidays, reverse-charge, per-jurisdiction rates — live in checkout today.
Cart abandonment recovery
Signed, cross-device recovery links bring shoppers back to the exact cart they left.
Referral & affiliate program
Merkle-attributed referrals with cryptographic inclusion proofs — attribution you can audit, not just trust.
Screenshot / image → build
Turn a screenshot or reference image into a styled build, brand-snapped to your palette via CIEDE2000.
Export & self-host — you own your build
Export any build to a self-hosted bundle: a static snapshot (provenance receipts + verify badge, no live governance), or the Premium runtime bundle that self-hosts the live governance layer while tethered to Signetify. Lose the tether → it gracefully collapses to static.
Agentic — on every plan
Built for the agentic era: delegate to agents under cryptographic governance, license your data, and pay for agent compute by the unit — no tier unlock.
Agent delegation grants
Issue scoped, revocable delegation grants to AI agents — Macaroons-style, HMAC + BLAKE3 lineage, W3C Verifiable Credentials. Every agent action traces back to a grant.
Training-data licensing & royalties
Opt any asset into training-data licensing with provenance + EU AI Act Art.10 lineage, and earn royalties when it's used to train.
SCU token economy — metered
The agentic compute currency: escrowed, refundable, priced in Agentic-Drive packs. Pay-as-you-go for exactly what your agents consume, on any plan.
Agent reputation report cards
Every agent operating in your tenant gets a reputation report card — behavior baselines, drift detection, and a signed forensic record of what it did.
Every capability above maps to a typed constant in lib/tier/capabilities.ts. Paid access is enforced server-side by a unified capability gate keyed to your subscription tier — derived from your billing, never a client-supplied value. Enforcement is rolling out across surfaces.
Knowledge estates — coming to every plan
Get paid for your knowledge and for how agents use it: per answer, per skill run, per session or by licence, at a price you set, under a no-training clause. In build; the agent gateway, grants and metering it sits behind are live today. Read more
