I've just published the new Unleash Toolbar to npm.

It's a client-side debugging toolbar for the Unleash, the open source feature flagging project.

It enabled on-page flags and context overrides, without requiring any API tokens or complex setup. You simply wrap the JS SDK in your code and everything else works seamlessly.

Also supports React and Next.js SDK, so you can use for any frontend application (including Angular, Vue, etc.).
