Pro licensing

The sv-grid-pro package is soft-gated: every feature runs without a key, with a small unlicensed-build watermark in the bottom-right corner of the grid + a one-time console nudge. Set a key once at app startup and both disappear.

Setting the key

import { setLicenseKey } from 'sv-grid-pro'

setLicenseKey(import.meta.env.VITE_SVPRO_KEY)

Call this before the first <SvGrid> mounts. In Vite/SvelteKit, expose the key as VITE_SVPRO_KEY=SVPRO-... in your .env (NOT checked in) - or read it from your config service.

License tiers

Every Pro license is a perpetual license that includes 1 year of updates and support. The price shown renews automatically each year to keep updates and support active; cancel anytime and you keep every version released during your paid term.

License	Apps covered	Price (per developer)	Support
Single Application Developer License	One deployed production app	$599	Email (next business day) + private Slack
Multiple Application Developer License	Unlimited apps in your organisation	$999	Email (next business day) + private Slack
Enterprise / volume	Unlimited	Custom quote	Priority + named contact, NDA / PO

Priced per developer - engineers who write or modify code that imports sv-grid-pro. Production seats / end users are unlimited. One license key activates every grid in scope - no per-page or per-component accounting. Teams of 5+ and multi-year terms get volume discounts; email [email protected].

License key format

SVPRO-IXIX-XXXX-XXXX-XXXX-XXXX
       │
       └── single hex-encoded payload, verified locally

The check is purely client-side, signed against our public key. No network call is ever made to validate. Air-gapped deployments work out of the box.

Per-environment keys

Different keys for different deployment stages so revoking is surgical:

const KEY = {
  development: import.meta.env.VITE_SVPRO_DEV_KEY,
  staging:     import.meta.env.VITE_SVPRO_STAGING_KEY,
  production:  import.meta.env.VITE_SVPRO_PROD_KEY,
}[import.meta.env.MODE] ?? ''

setLicenseKey(KEY)

Dev / demo key

For demos + integration tests, use the published sentinel:

setLicenseKey('SVPRO-DEV-DEMO')

This suppresses the watermark for local development. Do not ship this key to production - it's a dev-only convenience and will be revoked in any production-domain validation pipeline.

What happens without a key

Surface	Behaviour
Grid render	Works.
Editing, sort, filter	Works.
`pro.exportData(...)`	Works.
`pro.importData(...)`	Works.
`pro.ai.*`	Works.
`createPivotModel(...)`	Works.
Unlicensed watermark	Visible on every grid instance.
Console nudge	Logged once per page load.

Nothing is "trial mode" - the soft-gate is meant for evaluation. Once you're sold, drop in a key.

License renewal

The license itself is perpetual; what renews each year is your updates-and-support term. It renews automatically until you cancel (cancel anytime). The key keeps validating every version released during a paid term, and if you cancel or let the term lapse, your installed version keeps working - you just stop receiving new releases and support.

60 days before the term ends: yellow nudge on the watermark
30 days: orange
7 days: red
After the term ends (if you cancelled): features keep working; only versions released after your paid term need a renewed term

We never disable working features on a paying customer.

Audit trail

Each license key has a stable ID embedded. The same key activates as many builds as you want; the ID is what we cross-reference against your subscription in support tickets. No telemetry is sent - support uses the ID you give us, not anything we phoned home for.
