Questions & Answers

As answered by people managing Widin.io and Handler.

What makes your product unique?

Widin.io's answer

We use the Refine framework to help you easily create advanced and organized frontend features.

On the backend, we structure the codebase using Hexagonal Architecture best practices. This approach is crucial for a SaaS platform to effectively deliver advanced features.

Handler's answer:

Handler is built specifically for app marketers who want to find what is already working on TikTok. Instead of guessing content ideas, Handler helps teams discover outlier TikToks, understand winning patterns, and decide what to test next.

Why should a person choose your product over its competitors?

Widin.io's answer

Widin is the only starter that focuses on hexagonal architectures. It helps to start quickly but also to stay on the right track over time.

Handler's answer:

Handler is focused on TikTok research for app growth, not generic social media management. It helps marketers move faster from โ€œwhat should we post?โ€ to clear creative direction based on real winning TikToks.

How would you describe the primary audience of your product?

Widin.io's answer

Startup CTO launching a new product.

Handler's answer:

Handler is made for app founders, growth marketers, mobile app teams, indie app builders, and agencies that use TikTok to grow consumer apps.

What's the story behind your product?

Widin.io's answer

Having built several SaaS web apps from scratch, I developed over and over similar features. Trade-off between velocity and clean architecture are sometime made, while undesirable. Widin aims to provide a solution to that compromise.

Handler's answer:

Handler was created because app teams spend too much time manually scrolling TikTok trying to understand what content works. We built it to make TikTok research faster, clearer, and more repeatable for app marketers.

Which are the primary technologies used for building your product?

Widin.io's answer

Next.js, React.js, Typescript, Refine, Next Auth, GraphQL, GraphQL Codegen, Nest.js, Passport, CASL, Zod, Prisma, PostgreSQL, Vercel, Render.

Handler's answer:

Handler uses AI analysis, TikTok content research, video metadata extraction, creative pattern detection, and a web-based dashboard to help app marketers find and understand winning TikToks.

Who are some of the biggest customers of your product?

Handler's answer:

Handler is currently early, so we are not publishing customer names yet. The product is built for app founders, consumer app teams, growth marketers, and agencies working on TikTok-based app growth.
