The system that runs your business still works, but every change takes weeks, only one developer understands it, and it can’t connect to the tools your team wants to use.

Is Your Application Ready for Modernization?
Modernization usually pays off when three or more of these are true:
Small changes take weeks and often break something else
Only one or two people understand how the system works
The framework, language or OS is no longer supported
Hosting and maintenance costs rise every year
It can’t connect to modern tools, APIs or AI
Users rely on spreadsheets and workarounds to get their jobs done
Security or compliance reviews keep flagging the same system
Choosing the Right Strategy
Rehost
Hosting only (move to cloud)
The app works but servers are the problem
Replatform
Hosting + managed services
You want lower running costs fast
Refactor
Code structure, same features
The code is hard to change
Rebuild
New code, same business rules
The technology is obsolete
Replace
Off-the-shelf or new product
Your needs have changed completely
Most projects combine two or three strategies across different parts of the system.
App Development Company in Dallas
from new builds to app rescues
Pixarsart is an award-winning app development company in Dallas–Fort Worth, working with startups, growing businesses and enterprises. Some clients come to us to launch a new mobile app. Others need an existing app fixed, modernised or scaled. Choose your scenario below.
App development

You’ve validated the idea but don’t have engineers. Our senior team takes your app from concept to App Store and Google Play launch — without the cost and risk of hiring in-house.

an unfinished app project
Missed deadlines, half-built features and code no one understands. We start with a code audit, tell you what’s worth keeping, and deliver a clear plan to finish or rebuild.
Fix a slow, crashing
or poorly rated app
Crashes and one-star reviews cost you users every week. Our app maintenance and support team stabilises performance, fixes critical bugs and helps recover your ratings.
App modernization
for outdated technology

Technologies We Use
An app development partner for companies that choose quality over the lowest quote
Great products come from the right partnership, and the right partnership starts with honest expectations. Pixarsart isn’t the right fit for every project. That focus is exactly why our clients trust us with the products their business depends on.
Buyers comparing only hourly rates
If the lowest hourly rate is your main decision factor, there are cheaper options out there. We price for outcomes – senior engineers, proper QA and on-time delivery – because rework and missed launches cost far more than a lower rate saves.
Small fixes and quick website updates
Pixarsart focuses on building and scaling apps, software and AI products. For quick website fixes, WordPress or Shopify updates and urgent repairs, our sister brand alley214 offers fast, fixed-price help.
Teams that want to manage every developer task
We work best as an accountable partner, not a pair of hands to direct line by line. You set the goals and priorities, our leads manage delivery, and you keep full visibility of progress in Kanbaan.
Projects without clear ownership on your side
Every successful build has a decision-maker who can review work and give timely feedback. If no one on your team can own the project, we’ll recommend starting with a short discovery workshop first.

Application Modernization FAQs
What is application modernization?
Updating older software — its code, architecture, hosting or interface — so it’s easier to change, cheaper to run and able to connect to modern tools.
Do we have to rewrite everything?
Rarely. Most systems are modernized in phases, keeping the parts that still work.
Will our users be disrupted?
We replace one module at a time and keep the old system running until each new part is ready.
How long does modernization take?
An assessment takes 2–3 weeks; modernizing one module typically 2–5 months; full platforms are phased over 6–18 months.
How does AI help modernization?
AI speeds up code analysis, documentation and test creation, and assists code conversion. Our engineers review every change.
Can you modernize software another company built?
Yes. Most of our modernization projects involve code written by other teams, often years ago.
