About

Who Stainless Code is, how we ship open-source libraries, and where product docs live — without a platform pitch.

We ship libraries, not a platform.

Stainless Code is the GitHub org and company hub behind open-source TypeScript and JavaScript tooling for modern apps and AI-agent workflows. This site indexes those libraries and states how we ship. Product guides stay on each library’s own docs.

Why Stainless Code

Sharp contracts — Public APIs you can pin and reason about.
Independent libraries — Pick what you need. MIT-licensed, no forced stack.
Built for agents too — Machine-readable docs and predictable packages where agents work.

Hub vs product docs

This domain root is the company index: pitch, catalog, and outbound links. Each flagship library owns its docs tree:

Product	Docs
Codemap	stainless-code.com/codemap
Persist	stainless-code.com/persist
Layers	stainless-code.com/layers

Full one-liners, npm packages, and legacy utilities: product index.

How we ship

Source and issues live under the stainless-code GitHub org.
Packages are typically MIT — confirm in each repo’s license file.
Prefer agent-readable docs (llms.txt) and clear package contracts over sprawling frameworks.
Want to help? Open an issue or PR on the relevant product repo. There is no separate company contribution guide beyond each library’s docs.

FAQ

Is Stainless Code a platform?

No. We ship independent open-source libraries — not a unified suite or hosted platform. Pick the packages you need.

Where do product docs live?

Each library has its own docs site under stainless-code.com (for example /codemap, /persist, /layers). This hub is the company index and pitch — not a second copy of those guides.

How do Codemap, Persist, and Layers differ?

Codemap indexes a local codebase for agents (SQL and recipes instead of scanning the tree). Persist adds hydration-aware persistence to reactive stores. Layers is a headless overlay manager — open any layer from anywhere. Different problems; no forced stack.

Are the libraries open source?

Yes. Work lives under the stainless-code GitHub org and is typically MIT-licensed. Check each package for its license file.

What is llms.txt?

A machine-readable docs map for AI agents. Product sites publish llms.txt so agents can navigate the docs without scraping the whole tree.

Who maintains Stainless Code?

Today, founder and maintainer Sutu Sebastian. Team has profile links; Contact has the company email for partnerships.

Does Stainless Code have a client portfolio?

Stainless Code ships open-source libraries. The Experience page covers the founder’s background — SoftState, Flowbite React, and other product work — with client attribution kept on those companies’ own sites where it belongs.
