IsValid is a validation API service for developers who need to quickly verify data formats without building their own validators. It offers 40+ endpoints covering financial identifiers (IBAN, BIC, ISIN, CUSIP), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), regional codes (PESEL, REGON, VAT), and more.

The service works on a freemium model โ€” 100 free API calls per day, no credit card required. Users manage API keys through a dashboard with usage analytics showing daily call volume and per-endpoint breakdowns.

IsValid.dev features and specs

  • Lightweight schema validation
    IsValid.dev offers a minimal, lightweight approach to schema validation for TypeScript, avoiding the bloat that can come with larger validation libraries.
  • TypeScript-first design
    Built with TypeScript in mind, providing strong type inference so validated data automatically gets proper TypeScript types without extra manual typing.
  • Simple API
    The library offers an intuitive and easy-to-learn API for defining and running validations, making it accessible for developers to quickly get started.
  • Zero or minimal dependencies
    Being a lightweight tool, it typically has little to no external dependencies, reducing bundle size and potential security/maintenance issues from third-party packages.
  • Good for small to medium projects
    Its simplicity makes it well suited for smaller projects or use cases where heavier libraries like Zod or Yup might be overkill.

Possible disadvantages of IsValid.dev

  • Smaller community and ecosystem
    Compared to established validation libraries like Zod, Joi, or Yup, IsValid.dev has a much smaller user base, meaning fewer community resources, tutorials, and third-party integrations.
  • Limited documentation
    As a newer or less mainstream tool, its documentation may be less comprehensive than more established alternatives, making it harder to find answers to edge-case questions.
  • Fewer advanced features
    It may lack some of the advanced features found in more mature libraries, such as extensive built-in validators, custom error message localization, or complex schema composition tools.
  • Less battle-tested
    Being less widely adopted, it may not have been tested against as many real-world edge cases as more popular libraries, potentially leading to undiscovered bugs.
  • Uncertain long-term support
    Newer or niche libraries carry a higher risk of reduced maintenance or discontinuation over time compared to well-funded or widely-adopted projects.

Analysis of IsValid.dev

Overall verdict

  • IsValid.dev appears to be a developer-focused validation/utility tool that can be useful for quick, lightweight validation tasks, though I don't have verified, up-to-date details on its full feature set or reliability track record.

Why this product is good

  • Likely offers a simple, developer-friendly interface for validation tasks
  • Probably free or low-cost, making it accessible for quick checks
  • May support common validation formats (e.g., JSON, schemas, or data formats) useful in development workflows
  • Could save time compared to writing custom validation scripts for simple use cases

Recommended for

  • Developers needing quick, ad-hoc validation checks
  • Small projects or prototypes where a lightweight tool suffices
  • Users looking for a free or low-cost alternative to more complex validation suites
  • Learning or testing purposes rather than mission-critical production validation

Questions & Answers

As answered by people managing Nodewood 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

  • Launchpad to quickly start a SaaS business?
    Hey, thanks for the mention! I'm the creator of Nodewood, and I'm happy to answer any questions anyone has on it, or really anything else in the space I can help with. Source: over 3 years ago
  • Build Your Own Web Framework
    This is largely why I built Nodewood [1]. Every time I wanted to start a new project, almost always a SaaS idea, I'd skip over the "boring stuff" like building user management, subscription management, teams, admin, all that, to get to the meat of the business logic, to make sure I had a valid idea. But I still needed all that stuff eventually, so I'd have to lose time later building it all in! So I decided to... - Source: Hacker News / about 4 years ago
  • Fresh is a new full stack web framework for Deno
    This is actually part of why I created Nodewood [1], because every new Node project required pulling all that together, and every new SaaS idea I had had the same basic requirements (user management, subscription management, teams support, etc). Then I figured, if I found this useful, surely others would too, so I packaged it up and have had a few happy customers since then, who have helped me refine it, which... - Source: Hacker News / about 4 years ago
  • Ask HN: Side projects that are making money, but you'd not talk about them?
    Well, I've spoken about this before, and on here no less, but only really in response to posts like this. I don't do any advertising or speak about mine except in interviews, since it's usually indicative of the kind of requirements they're looking for. I created a SaaS bootstrap for Javascript called Nodewood [1]. It actually started as just a template for me, because there's a lot of setup for each new JS web... - Source: Hacker News / about 4 years ago
  • Ask HN: Best SaaS Boilerplate?
    Disclaimer: I'm the author of the following boilerplate. Nodewood (https://nodewood.com/) is a Javascript SaaS boilerplate built to take advantage of using Javascript on the server and in the UI. Models, Validators, and other business logic can be re-used in both builds, so you don't have to write, rewrite, and maintain that logic in both places, or in different languages. It has built-in subscription management... - Source: Hacker News / over 4 years ago
