Two kinds of machine were modelled as one. A host somebody brings is theirs, reached through a team, and should die with their account. A host bought to serve other people's workloads is none of those things — and there was nowhere to put it, so it had to be registered under an employee's personal team, where it was that person's property and their account going away took it with them. Ownership becomes an either/or. A machine names a team or an organisation, exactly one, enforced by a check constraint rather than by convention: both null is a host nothing can bill, and both set is two answers to "whose is this?" where whichever join a query happens to take decides who pays. Hardware an organisation owns has no team and no person at all, which is the point. The organisation is deliberately not a billing subject and has no plan columns. It says who owns the metal; a team pays for what it uses either way. Membership is derived from a verified email domain rather than stored. An address is already the root identity, so a second record of who belongs where is a second answer that can disagree with the first — and deriving it means signing in with a personal address still gets an ordinary personal account, which is what lets one person hold a company account and use the consumer product. Nothing is granted on an unverified domain or an unverified address: either one is a string somebody typed. Entitlement on fleet hardware refuses everyone for now, with a reason that says so. What grants a run on metered hardware is a plan, and there is nothing to ask yet, so it fails closed rather than giving the expensive case away. The branch is written out so the plan check has one obvious place to land. Routes are read-only, and nothing seeds an organisation. Creating one grants membership to everyone who can receive mail at a domain, so it is an operator action against the database — a migration that inserted one would insert it into every deployment, including ones we have nothing to do with. See docs/deploy.md.
apps/api
The public HTTP API for Nestri — a Hono app. One handler, run either as a Cloudflare Worker or as an ordinary HTTP server.
What it does
Exposes the JSON API consumed by frontends and other clients. Every route is a thin wrapper that
validates input, delegates to a domain function in @nestri/core,
and returns { data: ... }. All business logic lives in the core package.
Routes:
| Prefix | Purpose |
|---|---|
/ |
Health check |
/user |
Current user profile, fingerprints, linked accounts |
/steam |
Link / sync / unlink a Steam account |
/library |
Owned games with playtime |
/games |
Game catalog |
/pairing-code |
Device pairing codes |
/machine |
Host machines |
/access-token |
Short-lived access tokens |
/doc |
Generated OpenAPI spec |

Key details
- Auth:
Authorization: Bearer …, carrying either a session token verified against@nestri/author a personal access token resolved from the database; or a registered host's ownx-nestri-machine-idandx-nestri-machine-secret. There is no shared secret and no credential that stands for more than one caller, so every route resolves to a specific user or a specific host — which is what lets a route say "the caller's own library" and mean it. - Errors: centralized
VisibleError→ typed JSON responses. - Settings arrive as bindings or as environment variables, and two of them have one spelling of
each: Postgres is
HYPERDRIVEorDATABASE_URL, and the route to the issuer is anAUTHservice binding orAUTH_INTERNAL_URL. Nothing here branches on which it got. AUTH_ISSUER_URLis the issuer's public URL and never the internal one, because it is compared literally against theissclaim on every token.
Running
bun run dev # under the Workers runtime, on :3000
bun run serve # as a plain process, on $PORT (default 3000)
Needs a Postgres database and a reachable issuer. Full list and deployment steps:
