Questions & Answers

As answered by people managing SquareSpace and IsValid.dev.

What makes your product unique?

IsValid.dev's answer:

IsValid offers 70+ validators in a single API โ€” covering financial identifiers (IBAN, BIC, ISIN, LEI), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), tax numbers (VAT, REGON, PESEL), credit cards, phone numbers, and more. No need to integrate multiple services for different data types.

Why should a person choose your product over its competitors?

IsValid.dev's answer:

Most validation APIs focus on one category (email or phone). IsValid covers financial, regional, and technical formats all in one place with a consistent REST API. The free tier with 100 calls/day requires no credit card, and integration takes minutes.

How would you describe the primary audience of your product?

IsValid.dev's answer:

Developers and software teams building applications that handle user input, financial data, or international identifiers โ€” particularly in fintech, e-commerce, and SaaS products.

What's the story behind your product?

IsValid.dev's answer:

IsValid was built out of frustration with piecing together multiple validation libraries and services. The goal was a single, reliable API that handles the full range of data validation needs developers encounter in real-world applications.

Which are the primary technologies used for building your product?

IsValid.dev's answer:

Next.js, Fastify, PostgreSQL, Docker

WordPress vs. Proprietary Site Builders: What to Know Before Starting a Website Development Project
Squarespace: Squarespace lacks a formal backup and restore system. While you can export certain data (e.g., blog content) in XML format, thereโ€™s no full-site backup option. Restoration is limited and often requires direct support intervention, making business continuity less autonomous and more dependent on Squarespaceโ€™s policies.
