PUBLISHED BETA TERMS · evaluation-2.0

Know the limits before connecting.

Evidence available to read: Read evidence for 3 days from its first receipt.
Collection requests: Up to 1,000 collection attempts per workspace per UTC day, 50 per minute and 4 at a time.
Evidence reads: Up to 200 evidence reads per workspace per UTC day, 30 per minute and 4 at a time.
Owned workspace: One owned workspace per account; up to 10 active customer workspaces across the beta.

Duplicate, invalid and connection-check requests count as collection attempts. Shared budgets can reject requests before your own limit is reached. No automatic overage charges.

Each delivery can produce several events. The collection limit is a request budget, not an execution allowance.

Read these published beta terms or check the current terms for the full scope and limits.

BEFORE YOU CHOOSE

Start free.
Review the beta scope.

The free beta supports one Node.js → PostgreSQL outbox → BullMQ → webhook delivery path. You will add observation code to your app; installation alone does not send evidence. Review the current evaluation terms before connecting. The installation guide takes you from your key to the first execution in the dashboard.

A few things to know.

Does one collection attempt mean one execution?

No. A delivery can produce several evidence events, and each collection request uses the request budget. Duplicate events, invalid requests, and connection checks also use that budget. The limit does not promise a number of stored events or complete executions.

What happens if I reach a collection limit?

Collection can be limited by workspace usage, shared service budgets, or concurrent requests. Follow any wait time shown before checking again. Reaching a collection limit can leave gaps in evidence; it does not stop your business operations. Existing evidence remains subject to its retention window. There are no automatic overage charges in the free beta, and paid plan allowances remain proposals.

When does the retention period start?

Retention starts when each piece of evidence is first received by the collector. Retransmitting it does not extend that window. The published beta terms provide three days of Evidence reads. Read expiry, live deletion, and provider backup expiry are separate; see the privacy notice for details.

Do I pay for each teammate?

The beta is free, and no per-seat fees are proposed for paid plans. You can create a workspace for your application. Access to an existing workspace still requires a grant from its operator; logging in does not grant access to someone else’s evidence.

Can Nestarc retry or recover a delivery?

Nestarc is read-only. It shows the last confirmed delivery boundary and distinguishes a reported failure from an unknown outcome or interrupted evidence. It does not replay, retry, or recover your business operations.

Can I subscribe now?

Paid subscriptions are not open yet. Prices, usage limits, retention windows, and support for Starter and Team are proposals being validated. You can start the free beta now and connect your own supported application. No payment method is required.
