Questions & Answers

As answered by people managing JSFiddle and ASO.dev.

What makes your product unique?

ASO.dev's answer:

ASO Toolkit with NO limits on keywords or apps made by developers for developers

How would you describe the primary audience of your product?

ASO.dev's answer:

We build ASO.dev for everyone who manages apps on the App Store - from independent developers to major mobile publishers. Whether you run a single app or a whole portfolio, we help you automate the repetitive work and focus on what really drives growth.

Why should a person choose your product over its competitors?

ASO.dev's answer:

ASO.dev gives you complete freedom - no limits, no restrictions. You can track unlimited keywords, apps, and developer accounts. All the keywords your apps rank for are automatically collected into a single, unified list - you don’t need to search or guess which ones matter.

Our automation tools handle repetitive App Store Connect tasks like metadata editing, bulk uploads, translations, and screenshots - saving hours every week for developers and marketing teams. Unlike most tools, ASO.dev combines keyword tracking, metadata management, reviews, and Apple Search Ads insights in a single dashboard, designed for both indie developers and large publishers.

In short: ASO.dev saves time, removes limits, and gives you full control over your App Store growth.

What's the story behind your product?

ASO.dev's answer:

ASO.dev was born from our own experience and frustration. After translating our app into 39 languages, we got tired of manually filling out What’s New, managing screenshots, and guessing which keywords users were searching for. We wanted a tool that would simply show all the keywords our app ranked for - and automate everything else.

So we built it ourselves. What started as a small tool quickly grew into a full platform - designed, coded, and scaled entirely by two people, bootstrapped from day one.

Today, ASO.dev helps developers and companies of all sizes save time, automate App Store workflows, and focus on growth instead of routine.

Built from our own pain, grown by passion - and still 100% bootstrapped.

Which are the primary technologies used for building your product?

ASO.dev's answer:

  • Flutter (multi-platform: macOS, Windows, iOS, Andoid)
  • .NET Core (C#) for API services and integrations
  • MongoDB for app data and user state
  • RabbitMQ for distributed task processing and queue management
  • Kubernetes
  • Rancher
  • Hosted on Hetzner
  • Data backups stored on S3-compatible storage
  • Apple App Store Connect API (metadata, screenshots, in-app events, pricing, etc.)
  • Stripe & RevenueCat for subscription management
