FlutterFlow vs OutSystems

FlutterFlow and OutSystems are both prominent platforms in the no-code/low-code landscape, but they cater to different audiences and use cases. FlutterFlow focuses on building applications using Flutter, Google's UI toolkit for creating natively compiled applications for mobile, web, and desktop from a single codebase. OutSystems, on the other hand, is an enterprise-level low-code application development platform designed for rapid application development with robust capabilities for scaling and integration.

Pushing No-Code to Its Limits

Launching an app has never been more cost-effective and time-efficient. Platforms like Bubble.io and Flutter Flow have transformed the development landscape, enabling developers to create sophisticated applications rapidly.

Fast and Cost-Effective Launch

No-code platforms empower startups to launch their apps at lightning speed—often multiple times faster than traditional development—at a fraction of the cost. This agile approach helps startups focus on growth and innovation rather than high upfront development expenses.

Agile Iteration

For early-stage startups, quickly reaching a problem-solution fit is critical. No-code platforms allow rapid adaptation, letting you implement and push new features live in a matter of hours, not weeks. This flexibility means you can stay responsive to market needs and iterate on your product with ease.

Seamless Integration and Plugins

Platforms like Bubble.io and Flutter Flow come with built-in integrations and a wealth of plugins, giving you instant access to essential features and functionalities. Whether you're building a Minimum Viable Product (MVP) or scaling up, these platforms make it easy to connect with tools you need, from payments to analytics.

Version Control Made Simple

Launching new versions of your app has never been easier. No-code platforms provide flexible version control, enabling you to create save points, roll back to previous versions if needed, and experiment confidently

VOLI Case Study: No-Code in Action

Before working with Mayfly, VOLI’s founder Charlie Crozier had approached 12 different development agencies. As a non-technical founder, Charlie struggled to get his app built and ready for users, with quotes ranging from $300,000 to $1 million. These high costs placed immense pressure on early capital raising.

“When we met Mayfly, both our budget and timeline were completely reevaluated. We were able to go to market at a fraction of the cost and time we had expected—without compromising on quality.”

—  Charlie Crozier, Founder

The Process:

Mayfly worked closely with VOLI through a series of workshops to deeply understand the product, its vision, and user needs. Leveraging no-code and low-code frameworks, we built an enterprise-grade app at a fraction of the cost quoted by other studios. Now in pilot testing, VOLI is preparing for release to 10 companies already on the waitlist.
