Webhook events — Billing is based on webhook events admitted to the platform. Each inbound event counts once regardless of how many delivery attempts or retries occur.
Retries — Retries are included in all plans and are not billed separately. Retry behaviour is bounded by the configured retry policy. Delivery attempt counts are visible as operational telemetry for debugging but do not drive billing.
Overage block size — 1 block = 25,000 additional events at €12 per block. Retries are always included and do not count toward overage.
Production activation is gated to keep identity and billing aligned.

Duerelay provides developer utilities for webhook debugging, operational calculations, and reliability-oriented workflows. These tools are available regardless of plan.
Plan limits apply to webhook event admission, retention, and production processing scope inside the Duerelay platform.
How is Duerelay billing handled?
All paid plans are billed via Stripe in EUR. Pick monthly or yearly — yearly saves the equivalent of two months. Activation is gated behind a profile-confirmation step so production scope and identity stay aligned. Self-serve plans run on a hosted Stripe checkout; Enterprise is invoiced on a negotiated contract.
What counts as a webhook event for billing?
Every inbound webhook admitted to the platform counts as one event. Each event counts once regardless of how many delivery attempts or retries occur — retries are always included and never billed. Policy-blocked requests and sandbox traffic do not count toward your plan quota.
How does overage pricing work?
Self-serve plans (Starter, Core, Scale and their AI variants) bill overage as a flat €12 per block of 25,000 additional events above your plan quota. There is no per-event charge and retries do not count toward overage. Enterprise customers negotiate overage as part of their contract.
Do I need an Agent (AI) plan to use Duerelay?
No. Gateway plans (Starter €19, Core €49, Scale €89) cover webhook delivery, replay, retries, idempotency, policy gates, and observability. Agent (AI) plans add the full Agent Control Plane on top: typed agent SDKs with per-agent credentials, atomic bundles with rollback, approval workflows, and OTEL traces.
Is there a free trial?
The free Sandbox is always available — one source, one relay, one endpoint, 1,000 events per month, full lifecycle (retries, replay, inspect, simulate). Core AI also offers a 30-day free trial with no card required, so you can evaluate the Agent Control Plane against real traffic before committing. See the quickstart to send your first event in five minutes.
Are developer tools free?
Yes. Duerelay developer tools are available regardless of plan. Plan limits apply to webhook event admission, retention, and production processing — not to the utilities themselves.
