Why teams pick @pyriter

TypeScript-first

Every package ships with full type definitions. Strict mode friendly, no `any` escape hatches in our public APIs.

Tree-shakeable

ES module entrypoints with explicit exports. Pull in only what you use — your bundle stays lean.

Battle-tested in production

These libraries power our internal infra and shipping products like Piezopy and Rezuned. We use them too.

Open source

GPL / MIT licensed and developed in the open on GitHub. Issues, PRs and discussions welcome.

Showcase

Built on top of these libraries

Production apps that use the same packages we publish. We dogfood our own work.

All projects

Need a custom build?

We also do consulting work — TypeScript, Node.js, and AWS infrastructure. If our libraries fit your stack, we'll fit your team too.
