Familiar HTTP
Receive a standard Request, return a standard Response, and use ordinary Web APIs.
PORTABLE WEB APPS · SELF-HOSTED PLATFORM
Servers exist.
Your app doesn't care.
Build a small TypeScript App against Web Standard Request and Response. Run it locally, manage it on your own nosrv Platform, or hand deployment to a supported cloud provider.
- Web Standard handlers
- Portable context
- Versioned deployments

ONE SMALL CONTRACT
Write the App.
Choose the runtime later.
nosrv keeps application code focused on HTTP, portable context, and declared resource capabilities. Provider details stay at the deployment boundary, so a useful internal tool does not have to begin as an infrastructure project.
Explicit resources
Declare database, KV, and storage needs and use runtime-provided environment, secrets, and identity instead of importing a cloud SDK.
Static and dynamic
Ship an API with a frontend, a static-only site, scheduled work, or a small file collection.
AI-readable by design
A compact specification, examples, and JSON management commands give coding agents firm boundaries.
THE APP CONTRACT
Small enough to understand at a glance.
The handler stays portable. Runtime services arrive through ctx, with
requirements visible beside the code that uses them.
import { defineApp } from "@nosrv/core";
export default defineApp({
requires: { db: true },
async fetch(request, ctx) {
const { rows } = await ctx.db.sql.query(
"SELECT * FROM notes",
);
return Response.json(rows);
},
});SELF-HOSTED, WHEN YOU WANT IT
A home for the small Apps your team keeps making.
Run one lightweight Platform with Docker or systemd. Deploy from another machine, watch linked source during development, and operate Apps from the browser or an agent-friendly CLI.
DeployAuthenticated Artifact upload with digest verification.
OperateStart, stop, restart, inspect logs, and list status.
Roll backKeep immutable versions and activate an earlier one.
PersistPer-App SQLite and files, or shared PostgreSQL and Redis.
START SMALL. KEEP AN EXIT.
Create
Begin with one handler, plain HTML, or even a lone index.html.
Iterate
Run locally or link source into Platform with automatic restarts.
Deploy
Send a versioned Artifact to your Platform or select a public target.
Grow
Move to dedicated infrastructure without rewriting the App boundary first.
