The whole application. Not just the front end.

appbuilder

| by modlix

Screens, database, business logic, logins, roles, customers and your own domain. All of it in one tool, with nothing left over for you to stitch together afterwards.

Most builders hand you beautiful pages and stop. Ours gives you the half that is actually hard: a real data model, logic that runs on a server, users who can sign in, and one app you can sell to a hundred different companies without forking it.

In production right now
These are not demos. They are the businesses we run.

Every site and app below is built on this platform, by this team, using the same App Builder you are about to open. Same components, same runtime, same deploy path. No hand-written escape hatch anywhere.

Every one of these is served from the same runtime you get. Open the network tab on any of them.

Why this one
Everything else stops at the halfway mark.

A website builder gives you pages and no data. An app builder gives you data, in their cloud, on their terms. An AI code generator gives you a repository and a new job as its maintainer. Every one of them leaves the second half of the work on your desk.

Site builders

Webflow, Wix, Framer. Gorgeous pages. Then you need a login, a database and a nightly job, and you are shopping for three more products and the glue between them.

App builders

Bubble, Glide, Retool. You get an app. Your data lives in their store, your logic in their proprietary blocks, and the export button either does not exist or produces something you cannot run.

AI code generators

Lovable, v0, Bolt. Ninety seconds to a prototype, then it is a codebase. You host it, you patch it, you upgrade it, and the next prompt quietly rewrites the file you fixed by hand.

App Builder is one product that covers all four layers, and hands you the keys at the end.

Comparison written from the published capabilities of each product as of August 2026. Where a competitor calls something possible with an add-on or a plugin, we said so rather than marking it absent.

What is actually in the box
Four layers. You get all four, or it is not an application.
Layer one · Screens

Pages that survive a real user on a real phone.

Drag components onto a canvas and bind them to your data. Not a template you fill in, an actual composition tree you control down to the pixel.

75+ components
, from Button and Grid up to server-paginated Tables, Charts, file upload, rich text and schema-driven forms.
16 breakpoints
, not three. Style anything per screen size, and per state, without writing a media query.
A theme, not a stylesheet.
Change one brand colour and every component in every page follows, including the ones you have not built yet.
Two people, one page, no locking.
Every component tracks its own version, so edits land side by side instead of overwriting each other.

Layer two · Data

A database you design, not a spreadsheet you outgrow.

Declare what a Job or a Customer is, with types, relationships and rules. The platform gives you the storage, the API and the audit trail without being asked.

Documents or tables.
Mongo when the shape varies, SQL when it does not. One definition either way.
Relations, uniqueness, defaults and validation
declared once and enforced everywhere, including in the AI's edits.
A REST API for free.
Every storage is queryable, filterable and paginated the moment you save it.
Row history and soft delete
when you tick the box, so "who changed this and when" is never a forensics project.

Layer three · Logic

Write it once. It runs in the browser and on the server.

Logic is a diagram of typed steps. The very same diagram validates a form in the user's browser and runs a nightly billing job on our servers. There is no second language and no bridge to maintain.

One definition, two runtimes.
Move a step from the browser to the server because it got sensitive, and nothing else changes.
Call anything.
REST APIs, your storages, email and WhatsApp, other functions, all as ordinary steps.
Scheduled jobs and event rules
without a cron box, a queue or a worker to babysit.
Step through it.
Run with sample input, watch each step's output, fix it, save. That is the debugger.

Layer four · People

Sign-in, roles and a hundred customers on one app.

This is the layer that turns a prototype into a product, and the layer nobody else gives you. It is here on day one, before you have written a page.

Real authentication.
Email, phone, OTP, social and single sign-on, with password and PIN policies you set.
Roles bundled into profiles
, then handed to people. Gate a page, a button, a record or an API call with the same switch.
One app, many organisations.
Each customer can have their own logo, their own fields and their own pages, on top of the one app you maintain. You do not fork anything.
Their domain, their branding, your codebase.
Sell the same product to fifty companies and ship a fix to all of them at once.

The AI part, honestly
It edits your application. It does not write you a codebase.

Ask for a change in plain language and the agent performs it as real, typed operations on your app: add this component, bind that field, create this storage, wire this function. Every operation is one you could have done yourself in the editor, which is exactly why you can inspect it, undo it, and trust it.

Describe it, get it

"A field-service app where technicians see today's jobs on a map." You get pages, storages and logic, not a wall of code to review.

Nothing is a black box

Every change the agent makes is a named operation on a named object, versioned like your own edits. Read it, keep it, or roll it back.

It sees what you see

The sidekick follows you. Ask "why is this table empty" while looking at the table, and it already knows which one you mean.

It remembers the app

Decisions, conventions and history are curated into the app's own knowledge base as you work, so month six is as informed as week one.

The last one is the one that matters over time. Most AI tools start every conversation from zero. Yours accumulates: why this storage is shaped like that, which naming convention you chose, what was tried and abandoned. The next person to open the app, or the next agent, starts with all of it.
Getting it out the door
Saved is shipped. There is no deploy step.

No build pipeline, no staging dance, no release ceremony. You save a page and it is live. When you want the real thing on a real address, it is one field in Settings.

Your own domain

Point it at us and we handle the certificate. HTTPS, renewals and the CDN are ours to worry about.

Mobile apps

Turn the same app into an installable Android and iOS build, from the same pages you already made.

Preview before anyone sees it

Every app has a live preview address from the first minute. Send the link, get the feedback, then point the domain.

Leave whenever you like

Export the whole application (pages, data model, logic, settings) as one file, and import it into any Modlix instance, including your own.

Who this is for
People who need the whole thing and do not want a team to build it.
Founders

Get to paying customers without hiring three engineers first. Billing, sign-in and tenants are already there.

Operations teams

The internal tool that runs on eleven spreadsheets and one person's memory. Model it properly in a week.

Agencies

Build once, sell it to every client with their own branding and domain, fix bugs in one place.

Product teams

Ship the admin screens, the customer portal and the marketing site out of one system, with one theme.

Consultants

Hand the client something they can actually keep, on their domain, exportable, not locked to your retainer.

Engineers in a hurry

Skip the fourteenth CRUD screen and the fourth auth integration. Drop to real logic only where it earns its keep.

How it goes
From an idea to a working address.
01
Describe it

A paragraph about what you want. The agent proposes the pages, the data model and the roles, and shows you the plan before touching anything.

02
Watch it get built

Storages, pages and logic appear while you read. Preview is live from the first page, so you correct course early instead of at the end.

03
Make it yours

Open any page in the editor and move things. Change the theme once. Add the rule the agent could not have known about.

04
Point a domain at it

One field in Settings. Certificate, CDN and sign-in are handled. Invite your team, or your first customer.

The questions you are about to ask
Straight answers.
Am I locked in?

Export your entire application as a single file whenever you want, and import it into any Modlix instance, ours or one you run yourself. The platform's runtime is open on GitHub.

Can I write actual code?

Yes, where it earns it. Logic is a typed step graph you can also read and edit as text, and you can call any external API. You are not stuck in blocks.

What happens when I outgrow it?

You mostly do not, because the layer underneath is a normal service architecture with a real database. When you do need something exotic, you add a service and call it as a step.

Who runs the servers?

We do, by default. Scaling, patching and backups are ours. If you would rather run it yourself, the stack is deployable on your own infrastructure.

Is my data mine?

Yours. It sits in a database per application, exportable in full, and we do not train anything on it.

How fast is fast?

A working internal tool in an afternoon is normal. The showcase above took weeks each, not quarters, and they are real businesses with real customers.

Can my whole team work in it?

Yes, at the same time, on the same page. Components version individually, so two people editing one screen is an ordinary Tuesday, not a merge conflict.

What does it cost?

Free while you build. You pay when you go live, on what you actually use. No per-seat tax for letting a colleague look at a screen.

Build the whole thing.
Open the builder, describe what you need, and have something real on a live address before the end of the day.
