Try PermitCore Live — Not Just the Docs

Download a tiny, real app in your language. Run it. Paste in a license key from your own PermitCore account. Watch it unlock — then flip a feature flag in your Admin and watch it change live. This is exactly the SDK integration your customers will build on.

Under 1 minute to run Full source included No database, no Docker

Download & run

Node.js, Python and PHP run with one command, no build step. Java, C++ and .NET need a normal build first — pick your language below.

Create a test license

In your PermitCore Admin — free, doesn't count against your quota.

Paste it in

The app activates and shows your plan, expiry, and usage.

Flip the "pro" flag

Add it to the license's Feature Flags, refresh — watch limits lift live.

The scenario

Task Manager Pro

A tiny task/project manager. On the Free plan it caps you at 3 projects and disables CSV export. Add the pro feature flag to the license in your Admin, and both unlock immediately — no redeploy, no restart. It's the same features array every PermitCore license already returns from validate()/activate(); this demo just reacts to it.
