Etapsky develops open-source software and technology products focused on documents, data, and developer infrastructure.
An open document format that combines human-readable visuals with machine-readable structured data in a single file.
TypeScript SDK for producing and consuming SDF files. Works in Node.js, browser, and Electron environments.
CLI utilities, integrations, and infrastructure tooling for modern software teams.
Our core work is open source. We believe good infrastructure belongs to everyone.
Every product starts with the developer experience. Simple APIs, clear documentation, zero magic.
We build on open standards and design for composability — no lock-in, no walled gardens.
We move in phases, ship working software, and iterate. Step by step.
