# Awesome PETs — Privacy Enhancing Technologies [](https://awesome.re)
|
||||
|
||||
> A curated **map of the privacy-enhancing technology stack** — the cryptographic primitives, protocols,
|
||||
> and systems you use to *build* privacy into products and research.
|
||||
>
|
||||
> **For builders and researchers, not switchers.** If you're looking for "use this app instead of Google,"
|
||||
> see [awesome-privacy](https://github.com/pluja/awesome-privacy). This list answers the other question:
|
||||
> *which primitive, protocol, or system do I reach for?*
|
||||
|
||||
PETs are the technologies that let data be **used without being exposed** — computed on, queried, shared,
|
||||
or transmitted while staying private. This list organizes them into a practical 7-tier stack (synthesized
|
||||
from the [ENISA](https://www.enisa.europa.eu/publications/pets-evolution-and-state-of-the-art), UN, and
|
||||
OECD PET taxonomies) and links out to the excellent per-discipline lists for depth.
|
||||
|
||||
> **🚧 Skeleton / work-in-progress.** Seeded with well-known projects; entries to be verified, expanded, and
|
||||
> annotated. Contributions welcome.
