How it works

Idea to production. In three steps.

AI does the heavy lifting. Senior engineers make every decision that matters.

Who it’s for

Built for founders and product teams.

Here is where it works best, and where it doesn’t.

Data-driven products

Dashboards, reports and analytics inside the web app.

AI-first products

LLM features, search and recommendations on the same stack.

Admin-heavy platforms

Django's admin, roles and workflows out of the box.

Booking and marketplaces

Listings, schedules and payments with background jobs.

Teams with Python developers

One language for the web app, data and ML.

Founders with a Python prototype

Turn a script or notebook into a real product.

Not the right fit

Native-only mobile features at launch: pair it with an iOS or Android app.
Static brochure sites that a website builder handles well.
Certified compliance from day one, such as HIPAA or PCI audits.
Open-ended hourly work without a defined first release.

How we work

Six stages, one team.

Pricing

Start free. Ship at a fixed price.

Two steps. The prototype costs nothing, and the release costs exactly what we agree.

FAQ

Questions, answered.

Straight answers about cost, timing, quality and ownership.

How much does it cost to build a Python web app?

The price is fixed for the agreed scope and set before work starts. You first get a free working prototype of the core flow in 1 day, then a fixed price and release date for the production version.

How long does it take to build a Python web app?

A working prototype takes 1 day. The production release date is agreed upfront and depends on the scope; AI speed with senior engineering makes it much faster than classic development.

Django or FastAPI?

Django when you want its admin, ORM and batteries included, FastAPI for lean, typed APIs and AI-heavy products. We recommend one on the call.

Do we need a separate JavaScript front end?

Not always. HTMX keeps the interface fast and interactive from one Python codebase; we add React only where it pays off.

Can it run AI features?

Yes. Python is the natural home for LLM features, retrieval and model serving, right next to the web app.

Is the prototype really free?

Yes, with no commitment. After a 30-minute call we build a working prototype of your core flow in 1 day, and then you decide whether to continue to the release.

Will the price go up during the build?

No. The price is fixed for the agreed scope. Anything new you want to add mid-build is priced separately and built only after you approve it.

Who owns the code?

You do, 100%. The source code, repository and accounts are yours, and the release ships to production under your name.

Is AI-written code safe to ship to production?

It ships only after senior review. Senior engineers own the architecture, security and code quality, and automated tests run on every change.
