Licenses
The core of schakl. is open source (AGPL-3.0): the platform itself plus the Klanten (Clients), Contactpersonen (Contacts), Taken (Tasks) and Meldingen (Notifications) modules. The extension modules are governed by the commercial license and require a license key. There are eighteen of them today: Projecten (Projects), Uren (Time), Verlof (Leave), HR, Domeinen (Domains), Websites, Hosting, Abonnementen (Subscriptions), Facturatie (Invoicing), Contactmomenten (Interactions), Automatisering (Automation), Marketing, Rapportage (Reporting), Klantportaal (Client portal), Google Workspace, Cloudflare, OXXA and Mollie — plus two surfaces that are not modules in the list but carry a license entry of their own: the MCP server and AI assistance. The source of those modules is plainly visible in the repository; only using them requires a key.
Every extension module has its own license entry, so a license need not cover all eighteen.
Instellingen → Licentie (Settings → License) lists all of them under Gelicentieerde
modules (licensed modules) with a status per line, so you can see per module whether your
key covers it. Two lines are still shown by their technical name, reporting and mcp —
Rapportage (Reporting) and the MCP server. Which modules are switched on is settled under
Instellingen → Modules (Settings → Modules).
How it works
Section titled “How it works”- A license key is a signed block of text (
SCHAKL1.…). You paste it under Instellingen → Licentie (Settings → License), visible to the instance owner only. - Validation is fully offline: your server never needs to “phone home” to keep running — even if our infrastructure is unreachable.
- The license states who it belongs to, which modules it covers and until when it is valid. All of that is shown on the license page.
Trial window
Section titled “Trial window”Every fresh install (and every existing install upgrading to this version) gets a
built-in trial: licensed modules work fully for fourteen days without a key. After that
they can no longer be enabled, and already-enabled licensed modules turn read-only. The
clock starts the moment the database is migrated to this version; the end date is shown on
Instellingen → Licentie (Settings → License) as Modules zonder licentie worden
alleen-lezen op (unlicensed modules turn read-only on). Set
SCHAKL_LICENSE_BOOTSTRAP_GRACE_DAYS for a different length.
When a license expires
Section titled “When a license expires”- A license may carry a grace period of its own: a number of days past the expiry date in which everything keeps working, so there is time to renew. How long that is comes from the key itself and therefore differs per license — there is no fixed number of days in the software. The end date is shown on Instellingen → Licentie as Respijtperiode tot (grace period until), with the status Verlopen (respijtperiode) (expired, in grace). If the key states no grace, read-only starts on the expiry date itself.
- After that, licensed modules turn read-only: existing data stays visible and export always works. Nothing is ever lost; installing a new key makes the module fully functional again immediately.
- The trial above does not bring an expired license back. That clock only covers modules that no installed license lists at all.
- The rest of the platform is unaffected.
Getting or renewing a license
Section titled “Getting or renewing a license”Get in touch through the channels on the website. Renewal is pasting a new key on the same page — that is all there is to it.
