We build interactive systems. Play one.

Signal Tap — nodes light up across the grid, tap them before they fade. Built the same way we build everything else: small, fast, and precise.

LEGEND

Node
Lights up briefly — tap it, or move the cursor and press Enter, before it fades.
Bonus
A rarer, brighter node worth triple points.
Combo
Consecutive hits multiply your score. A miss resets it.

10/16 · About

A small studio, built with intent.

AppVengers Code is a small, highly technical team that works closely with its clients — these are the principles we hold ourselves to on every project.

  1. 01

    Engineering-first

    We start from the system, not the screen. Every feature is scoped and architected before a single pixel ships, because a good idea built on a bad foundation still fails.

  2. 02

    Business-focused

    Code that doesn't move the business is just noise. We measure what we build against the problem it was meant to solve, not against how it looks in a portfolio.

  3. 03

    Scalable

    Nothing we ship is disposable. We build with growth in mind: types where they prevent bugs, infrastructure that doesn't need a rewrite under load, and code the next engineer can read.

  4. 04

    Long-term

    We don't disappear after launch. We stay close to what we build, because the real cost of software shows up later — in maintenance, in support, in decisions nobody had time for during the sprint.

11/16 · Client Voices

What it's like to work with us.

Real feedback from real projects — every quote here was submitted by a client and approved by us before it went live.

They rebuilt our online store from the ground up, and it showed within weeks — checkout conversion is up and support tickets about broken pages stopped.
Marta Delgado · Norda Home
What stood out wasn’t just the code, but how much thought went in before a line was written. Six months in, nothing we’ve changed has meant a rewrite.
Julien Faure · Lumen Logistics
We came in with a rough idea and a tight deadline. They scoped it fast, kept us updated the whole way, and shipped on time without cutting corners.
Priya Nair · Arclight Studio
Our booking process used to mean a spreadsheet and a lot of back-and-forth phone calls. Now it just works, and our team actually likes using it.
Tomás Rivera · Rivera & Co.

Indicative figures only. The real cost depends on scope, integrations and timeline — you'll always get a fixed quote before any work starts.

14/16 · Straight Answers

Questions worth answering up front.

The things most people ask before they get in touch.

  • The ranges on the Pricing section are honest starting points, not a quote — every project gets scoped individually once we understand what you need. You'll always get a fixed price before any work starts, so there's no surprise invoice halfway through.

  • It depends entirely on scope — a landing page moves in weeks, a custom platform in months. We set a real timeline together during scoping, before you commit to anything, so it's specific to your project rather than a generic estimate.

  • You do, entirely, once the final invoice is paid. No lock-in, no licensing fees to keep using what you paid for — the repository and every asset in it are yours.

  • We don't disappear. The real cost of software shows up later — in maintenance, in support, in decisions nobody had time for during the sprint — and we stay close to what we build for exactly that reason.

  • A freelancer can disappear mid-project; a big agency puts an account manager between you and the people actually writing the code. We're small enough that you work directly with the engineers building your product, and established enough to be there when you need support next year.
