Formtastic

Project Overview

Formtastic is a service for creating forms and surveys used in business scenarios with high requirements for stability, speed, and interface flexibility. As the project grew, it became clear that further development required not only updating client technologies but also targeted optimization of the server side.

Migration from Django to Nuxt

Initially, Formtastic's frontend was implemented using Django templates. This allowed for a quick start, but over time, this approach began to limit product development. The interface became more complex, changes required backend developer involvement, and the server was doing too much HTML rendering work, which negatively impacted scalability.

As a result, we architecturally separated the system. Django remained as the main backend and API, while the entire user interface was moved to a separate Nuxt frontend. This provided clear separation of concerns and allowed the interface to evolve independently from server logic.

After migration, UI development speed increased noticeably. The team started releasing new screens faster and improving user experience, while server load decreased as it stopped handling page rendering. Nuxt with SSR and SSG also provided significant gains in SEO and loading speed, which positively impacted marketing and public pages.

In parallel, the server side began to evolve. In areas with increased load and strict performance requirements, part of the logic was extracted from Django and implemented in Go as separate services. This reduced latency, simplified horizontal scaling, and eliminated bottlenecks without completely reworking the backend.

Migration from Native Apps to Flutter

Formtastic's mobile clients were initially developed as two independent native applications — for iOS and Android. As the product grew, this approach became increasingly inefficient: development slowed down, features were released out of sync, and maintaining two codebases increased the total cost of ownership.

The transition to Flutter allowed us to consolidate mobile development into a single codebase. This significantly simplified maintenance and made new feature releases predictable. Updates began rolling out simultaneously on both platforms, and the interface and app behavior became completely consistent for all users.

From a business perspective, the effect was direct: development and maintenance costs decreased, time-to-market accelerated, and the team gained the ability to test hypotheses and develop the product faster without proportional cost increases. At the same time, Flutter allowed us to maintain high performance and quality user experience.

Summary

Formtastic is an example of deliberate technological evolution of a product. Moving the frontend from Django to Nuxt simplified web version development and provided gains in speed and SEO. Targeted use of Go on the server solved performance issues without radical platform changes. The transition from native mobile apps to Flutter reduced ownership costs and accelerated product development. As a result, the system became more stable, flexible, and better prepared for scaling.
