What are app builders?

App builders—also called apps builder, builder apps, or app builder platforms—are tools for creating software applications faster, easier, and (in many cases) without writing a single line of code.

If your role in your company includes addressing a backlog of requests for new and updated software, chances are you've looked into an app builder online. And with over 22,000 searches a month for terms like app builders and apps builder, it’s clear that demand isn’t slowing down.

But with hundreds of tools on the market, from easy app builders for personal use to full-scale platforms built for developing software for the enterprise, how do you choose the right one?

Why app builders are surging and evolving

The normal process for software development is slow and expensive. Finding skilled developers is tough. Meanwhile, business stakeholders want solutions now, not in six months.

Enter the modern app builder. This solution is designed to build apps without coding, streamline the dev process, and help teams launch quickly. These platforms often offer drag-and-drop tools, templates, and prebuilt connectors for integration, enabling anyone to build apps with minimal friction.

But here's the kicker: Most app builders max out when it’s time to go beyond surface-level functionality. They’re not built for scale, governance, or long-term business value.

Best app builders: What to look for

What makes a tool the best app builder depends on your goals. Are you launching a prototype or building a mission-critical system? Are you solving one problem or digitizing an entire business process?

Here’s what sets the top app builders apart:

Must-have	Why it matters
No-code or low-code	Build fast without writing code and then scale with custom logic as needed.
Full-stack capabilities	Manage data, logic, and UX all from one platform.
Cross-platform app development	Publish to Google Play and Apple’s App Store without rebuilding from scratch.
Cloud-ready infrastructure	Deploy apps that take advantage of the speed, reliability, and global accessibility of the cloud.
Security and compliance	Build apps that are secure and address the compliance essentials for finance, healthcare, and government.
AI and automation	Speed up development and reduce technical debt with intelligent tooling.

OutSystems checks every box, and it does so with the power of a platform built for developing enterprise applications, not a hobbyist tool.

Easy vs. enterprise: App builders without coding

Searches like app builder easy, app builder without coding, and online app builders highlight a growing demand for simplicity. But simplicity doesn’t mean sacrificing power.

Let’s break it down:

Type	Best for	Limitations
No-code app builders	Non-technical users, fast MVPs	Limited customization, scalability issues
Low-code platforms	Developers, IT teams, fast delivery	May require onboarding or governance
Custom app builders	Full control, mission-critical apps	Requires developer skills or platform expertise

Many tools fall short the moment your use case demands custom workflows, real-time data, mobile-native features, or integration with back-end systems.

By contrast, OutSystems gives you the speed of a drag-and-drop builder with the control of traditional code but without the headaches.
