Templates that ship themselves.

DeesseJS is the open template ecosystem for agent-aware apps. Built by the team behind the engine, every template ships MIT and is runnable from the first commit.

The main app

The deessejs org runs more than one product. There are the templates you can scaffold today, the contracts they all share, the SDKs and CLI you install them through, and a small set of sub-domain products that ship on the same defaults. DeesseJS is the surface that ties them together and tells the world what the org is for.

When a new template is published, when a contract version bumps, when the CLI gains a flag. DeesseJS is where it shows up first. The marketing site, the docs surface, and the registry all read from the same source of truth, so a release on one side reaches every surface on the other.

Edited by Nesalia Inc.

DeesseJS is published by Nesalia Inc., a small company that funds the work and owns the brand. The templates, contracts, CLI, and sub-domain apps are MIT. The brand, the curated registry, and the marketplace positioning stay ours.

That split is intentional. The source-code ecosystem is shared. Anyone can fork, ship, and contribute back. The product surface is owned: a single team gets to curate the registry, set the defaults, and steward what ships under the DeesseJS name.
