Is Your Dev Agency Using Modern Tech? A Non-Technical Checklist
A developer tells you they're building your app with "modern tech." You nod. You don't actually know what that means. It could mean they're using bleeding-edge frameworks from 2025, or it could mean they're using jQuery—which was last relevant in 2010.
The problem: developers love to say "modern" because it sounds good. But you need to understand what modern actually means. And you need to be able to evaluate whether what they're building will last, scale, and be maintainable.
You don't need to understand code to understand technology. You just need to know the right questions to ask. I'm going to give you a checklist that works for non-technical founders.
Is It Built with React, Vue, or Next.js?
What You're Looking For
Modern frontend frameworks let developers build fast, interactive applications that work on phones and computers. React, Vue, Next.js, and Svelte are all modern. They're actively maintained, have large communities, and can scale.
Modern (Good):
"We're building your app with React and Next.js." / "We use Vue with TypeScript." / "We're using Svelte for performance."
Outdated (Red Flag):
"We're using jQuery." / "We build with vanilla JavaScript and HTML." / "It's a custom framework we built ourselves."
Why it matters: jQuery was the standard in 2010. It's slow, hard to maintain, and doesn't scale to complex applications. If they're using it now, they're either behind the times or not serious about quality.
Is It Node.js, Python, Go, or Something Else?
What You're Looking For
The backend is the engine behind your app. Node.js, Python (Django/FastAPI), Go, and Java are all modern, well-supported choices. They're actively used by major companies. They have vast libraries and tooling. They scale to millions of users.
Modern (Good):
"We're using Node.js with Express." / "Our backend is Python with FastAPI." / "We built this with Go for performance." / "We use Java with Spring Boot."
Outdated (Red Flag):
"We use PHP 5." / "This is built on Ruby on Rails (older version)." / "It's a custom backend we wrote." / "We use older versions of frameworks."
Why it matters: PHP 5 is from 2004. It's slow, insecure, and hard to scale. Old Ruby on Rails versions lack modern security. Custom backends are unmaintainable. When your developer leaves, the next one has to learn your custom tech instead of using industry standards.
PostgreSQL, MongoDB, or MySQL?
What You're Looking For
PostgreSQL is the gold standard for relational databases. It's robust, free, and powers some of the biggest companies in the world. MongoDB is modern for non-relational data. MySQL 8.0+ works, but older versions are dated.
Modern (Good):
"We're using PostgreSQL." / "MongoDB for document storage." / "MySQL 8.0 with proper configuration."
Outdated (Red Flag):
"We use MySQL 5.0." / "SQLite for production." / "A custom database solution we built."
Why it matters: MySQL 5.0 is from 2005. It lacks modern features, security patches, and performance. SQLite is for small projects, not production apps with real users. If they're using something custom, you're locked into their tech and their understanding.
Cloud (AWS, Google Cloud, Vercel) or Shared Hosting?
What You're Looking For
Modern apps run on cloud infrastructure. AWS, Google Cloud, Azure, Vercel, Netlify. These platforms scale automatically, are secure, and cost less at scale. Shared hosting is cheap but slow, insecure, and can't handle growth.
Modern (Good):
"We deploy to AWS with auto-scaling." / "Running on Google Cloud Platform." / "Your app is on Vercel." / "Using Azure with containerization."
Outdated (Red Flag):
"We host on a dedicated server we manage." / "Shared hosting with cPanel." / "On an old server in our office." / "We use FTP to upload files."
Why it matters: Shared hosting is slow and can't scale. Managing your own servers is expensive and risky. Cloud platforms handle security, backups, and scaling automatically. If your developer is using outdated hosting, your app will be slow and unreliable.
Do They Use CI/CD or Just Upload Files?
What You're Looking For
CI/CD (continuous integration/continuous deployment) means code is automatically tested and deployed when it's pushed. GitHub Actions, GitLab CI, Jenkins. This catches bugs before they reach users. Uploading files via FTP is the 2005 approach.
Modern (Good):
"We have GitHub Actions running tests on every commit." / "Using GitLab CI for deployment." / "Automated testing with Jenkins." / "Every push triggers our CI pipeline."
Outdated (Red Flag):
"We upload files via FTP." / "Manual deployment to the server." / "No automated testing." / "Developer manually clicks a button to deploy."
Why it matters: Manual deployment is error-prone and slow. No CI/CD means bugs get to users. Automated testing prevents regressions. If your developer isn't using modern deployment practices, you'll have constant bugs and downtime.
Is Everything HTTPS? Are They Using Modern Security?
What You're Looking For
HTTPS (encrypted connections) is mandatory for any app that handles data. Modern security means secure headers, proper password hashing, protection against common attacks. If your app isn't HTTPS, data travels unencrypted across the internet. That's inexcusable.
Modern (Good):
"Everything is HTTPS." / "We use secure headers and CORS properly." / "Password hashing with bcrypt." / "Regular security audits."
Outdated (Red Flag):
"HTTP only, HTTPS is optional." / "Passwords stored in plain text." / "No security headers." / "Never heard of OWASP."
Why it matters: Security breaches are expensive and damage your reputation. If your app handles any user data, it needs modern security. Period. If they're not taking security seriously, they're not serious about your business.
Quick Evaluation Checklist
☐ Frontend: React, Vue, Next.js, or similar (not jQuery)
Modern frameworks are fast, maintainable, and have big communities
☐ Backend: Node.js, Python, Go, or Java (not old PHP)
Modern languages scale and have active communities
☐ Database: PostgreSQL, MongoDB, or modern MySQL
Modern databases are secure and performant
☐ Infrastructure: Cloud-based (AWS, Google Cloud, Vercel)
Cloud platforms scale automatically and handle security
☐ Deployment: CI/CD pipeline with automated testing
Automation catches bugs before users see them
☐ Security: HTTPS everywhere, modern security practices
User data must be protected with current standards
Let Experts Evaluate Their Stack

Modern Development: How AI Is Changing the Game
Understanding modern developer tools and how they impact project speed and quality.
You don't need to understand code to evaluate technology. You just need to know what matters: modern frameworks, secure infrastructure, automated testing, and proper deployment. If a developer can't explain why they chose their tech stack, or if they're using outdated technology, that's a red flag.
The tech stack they choose will determine whether your app is fast or slow, secure or vulnerable, scalable or stagnant. Before you hire, make sure they're building on a solid, modern foundation.
Use this checklist. Ask these questions. If they hesitate, that's your answer.
