What is FOSS — and why does it matter?

FOSS stands for Free and Open-Source Software.

  • Free as in freedom, not (necessarily) price: you can use it, study it, modify it, and share it.
  • Open-Source means the source code is public and auditable — anyone in the world can inspect what the software actually does.

The reason this matters

If the service is free, you are the product.

Google, Facebook, TikTok and friends don't charge you because your attention, behaviour and data are what they sell. FOSS flips that: the software is free and there's nothing to harvest, because the operator has no advertiser to please.

Why is this good for you?

  • Privacy. No hidden telemetry, no selling your data to advertisers. If a project tried to slip in something shady, the community would see it in the code and fork it.
  • No lock-in. Your data lives in standard formats on a server you (or someone you trust) control. You can leave any time and take your data with you.
  • Longevity. Companies pivot, get acquired, or shut down (Google Reader, anyone?). FOSS projects can be picked up and maintained by anyone — they outlive their original authors.
  • Cost. Free or cheap to run. The savings go into better hardware and backups instead of license fees.
  • Trust. Security researchers regularly audit popular FOSS. Bugs and back-doors have nowhere to hide.

Why is this good for everyone?

  • It's a public good — every fix and feature benefits all users of that software, globally.
  • It enables small operators (like this one) to offer services with the polish of a Big Tech company without surveillance-capitalism business models.
  • It keeps the internet diverse — fewer monopolies, more interoperability.

Every service on this site is FOSS. If you ever wonder "could I run this myself?" — yes, you can.
