Don't Panic

hitchhikers.earth is the front door to the Hitchhiker’s Guide to the Earth. It is a guide written by the people who use it. It is mostly harmless.

Douglas Adams gave the Guide two words on its cover, in large friendly letters. They are still the best advice we know.

The best place to begin is the Hitchhiker’s Declaration: the history of hitchhikers.earth as told from 2042, and an invitation to help build the Guide for real.

What the Guide Is

A Guide is a multimedia publication with performative logic. It does not only describe the world. It helps you act in it. The Guide to the Earth is many such guides, from democracy to time travel, each written by Hitchhikers on sites they steward. The sites federate, so each guide can quote, fork and build on the others. See Guides and Guidance.

The Guide stands on the Earth Edition that Douglas Adams launched in 1999, h2g2.com, and on twenty five years of Field Research since.

Who Hitchhikers Are

Anyone who writes, researches or broadcasts in the Guide. You do not need to be a fan.

Every Hitchhiker should hold three things of their own:

  • A name. A subdomain held by your own key, not rented from a platform. See Your Right to a Name.
  • A space to write in. A federated wiki site that you steward, with your pages and your history.
  • A voice on air. A place on the network of stations that starts with Hitchhiker FM.

Where to Start

And bring a towel.

  • Your Right to a Name

    Your Right to a Name

    Every Hitchhiker should hold a name of their own, a space to write and research in, and the freedom to take both anywhere. Here is how we plan to give it to them, with SIG(0) keys that never leave your device, a cooperative lease on the name, and the work of Adam Burns on sig0namectl and DNS leases.

  • A Constitution You Can Hear

    A Constitution You Can Hear

    What Hitchhiker FM brought to the Sound and Law stream at the Critical Legal Conference 2026 in London: a radio station that broadcasts a constitution being made, 240 constitutions mapped and read aloud in 3D, and a whale channel that asks who speaks for nature, and how honestly we label the voices of machines.

    Hitchhiker's Declaration

    A Wildly Improbable Declaration and Invitation, for Douglas Adams. The history of hitchhikers.earth as told from 2042: member-owned, built on h2g2 and twenty five years of Field Research, and not for sale to Sirius Cybernetics. And an invitation to you, whether or not you are a fan, to help us build the Guide for real.
