User metadata API

What is Blip?

The Blip service is a fast JSON API that gives you meta information about the client that you make the request from, including geolocation and browser identification (coming soon).



Here's what the response looks like when called right now, from your browser:

That's it, actually. For the code and more information, refer to the README at You can also file feature requests and bug reports on the issues page.

We make no guarantees about the accuracy of the geolocation, but we think it's precise enough to be quite useful.

What does it cost?

Blip is completely free. We run the service as a convenience to ourselves and to others. It's also open source under the MIT License, so you're free to deploy your own Blip service if you don't want to rely on ours.

What can I do with it?

  • Quick Geolocation
  • Determine Browser capabilities (soon)
  • Analytics
  • Location based personalization
