Build full-scale apps with frontend code — fully offline

Welcome to frontql offline

frontql is a revolutionary platform designed to empower developers to build entire applications using only frontend code, eliminating the need for traditional backend development.

With frontql you get complete, scalable applications from JavaScript, HTML and CSS alone — no servers to run and nothing to deploy beyond your frontend. frontql offline keeps your entire application, its database included, in the browser, so it keeps working when the connection does not. The API you already know is the API you call: sdk.fetch() takes the same arguments as fetch() and returns a real Response.

app.js

import frontql from 'https://offline.frontql.dev/sdk.js'

// fetch( -> frontql.fetch( : same arguments, a real Response
const res  = await frontql.fetch('/items?sort=-id&page=1,5')
const { err, result } = await res.json()

await frontql.fetch('/items', {
  method: 'POST',
  body: JSON.stringify({ name: 'widget', qty: 3 }),
})

// window.fetch is never touched — the live API still works

Test REST and SQL together.

Explore seeded users, products and orders; build GET, POST, PUT and DELETE requests; then query the same relational data in the SQL editor with a live response panel and request history.
