Guides · From scratch
Building an app from scratch in 2026 means picking one of three paths. You drive an AI builder yourself, you hire a studio to build it, or you take the hybrid route and prototype the idea before a team makes it production-ready. Then comes the engineering a prompt never covers. A small, real product runs ₪3K–18K and takes 2–4 weeks. Platforms with logins, payments and an AI engine cost more and take months.
This is the from-scratch chapter of our complete guide to taking a prototype to production. Same honest numbers we quote on calls, with the reasoning behind each path.
It means going from an idea to running software, and there are three realistic ways to get there. The tools changed a lot in two years. The work underneath them didn't.
The first path is an AI builder you drive yourself. Lovable, Bolt, Base44 and Replit turn a prompt into a working React app with a Supabase backend you own. You get a demo in a day. What you don't get is the hardening that keeps it standing once real users arrive.
The second path is a studio that builds the whole thing from planning: spec, design, backend, security and deployment, handed over as code in your own repo. The third is the hybrid most founders actually want. You prototype the idea yourself to prove it's worth building, then give it to a team that rebuilds the foundations. You keep the momentum and skip paying to design something nobody asked for.
The path decides the price far more than the feature list does. Here is what each one costs in the Israeli market, and what you actually own when it ships.
| Path | What you pay | Time to something real | What you own |
|---|---|---|---|
| Drive an AI builder yourself | Tool subscription, roughly $20–50/mo | Days | A working prototype, unhardened |
| Prototype, then harden it (hybrid) | ₪3K–18K on top | 2–4 weeks | Production software in your repo |
| Full studio build from planning | ₪35K–80K+ | 6 weeks–5 months | A platform built for scale |
The subscription looks cheap until the app touches a real customer. The moment it holds someone's data or card, the ₪3K–18K to decouple and harden it stops being optional. Why we price by scope instead of hours, and what each tier includes, is in what it costs to rebuild a no-code app for production.
A small production app takes 2–4 weeks, including penetration testing and a deployment we verify instead of assume. Larger platforms run 2–5 months, depending on integrations and how much environment testing they need.
The thing that moves the timeline most is not the number of screens. It's how much the app is trusted with. A trading dashboard we built spent three months on paper trading before it touched a real account, because a bug there loses real money. We've delivered 15 production apps this way, with two more in progress now.
Pick by one question: will a real customer trust this app with their data or their money? If the answer is no, and it is an internal tool, a demo for investors next week or a landing page, an AI builder is doing its job, and a studio build is money spent on a problem you don't have yet.
If the answer is yes, the hybrid path usually wins. You prove the idea cheaply, then pay once to make the single version that survives contact with users. Building the polished thing before anyone has confirmed they want it is the most common way founders burn a budget from scratch.
The part you can't see in a demo, which is most of the work. A prototype proves the idea. It rarely proves the app can be trusted with anything.
The usual gap is security. AI builders tend to decide permissions in the browser, with no server-side control, so anyone who opens the developer console reaches more than they should. Real authorization has to live in the database: Postgres row-level security enforces it on every query, not in client code a user can edit. Closing that gap before launch costs a fraction of closing it after a breach.
Spend is the other blind spot. One client ran an automated builder with no cap on concurrent jobs and no spending limit, left it alone for a day, and got an AI bill over $1,000. The prototype worked exactly as built. Nobody had built the brakes. The full list of holes we keep finding is in security holes we keep finding in AI-generated apps.
Start by writing down what the app has to do and who it has to be safe for, before you pick any tool. That one page decides which path fits and what it should cost.
One of our systems arrived as an idea with no code at all. It's now a legal document engine that runs on the client's own machine, reads their evidence database, and produces lawyer-grade letters in Hebrew, each verified through several gates before a person approves it. It exists because we mapped the goals first and built to them, not because someone prompted it into being.
