Kilnx documentation

Kilnx is a declarative backend language that compiles .kilnx source to a single standalone binary. Models, routes, SQL, auth, jobs, WebSockets, SSE, and tests live in one file. SQLite and PostgreSQL are first-class.

• Zero JavaScript, zero runtime dependencies for the user
• ~15MB self-contained binary
• Built for the htmx era

Minimal example

config
  database: env DATABASE_URL default "sqlite://app.db"
  port: env PORT default 8080
  secret: env SECRET_KEY required

model user
  name: text required min 2 max 100
  email: email unique
  password: password required
  created: timestamp auto

auth
  table: user
  identity: email
  password: password
  login: /login
  after login: /dashboard

page /dashboard requires auth
  query stats: SELECT count(*) as total FROM user
  html
    <h1>Welcome, {current_user.name}</h1>
    <p>Total users: {stats.total}</p>

One file. kilnx run app.kilnx starts a dev server with hot reload. kilnx build emits a standalone binary.
