Features and specs

What each product offers, as listed by its team.

RealValidito 5 features
IsValid.dev 5 features
  • Real-Time Phone Validation
    Instantly verify if a US or Canada phone number is valid, active, and correctly formatted — with carrier, line type, and location data returned in under 1 second.
  • Carrier Lookup with LNP Detection
    Identify the current carrier serving any phone number, including numbers ported between carriers. Detects mobile, landline, VoIP, and toll-free line types.
  • DNC & TCPA Litigator Screening
    Screen phone numbers against DNC screening data and known TCPA litigator databases to reduce compliance risk before dialing or texting.
  • Bulk CSV Validation
    Upload lists of up to 50,000 phone numbers for batch validation. Download enriched results with carrier, line type, and DNC status for every number.
  • REST API & CRM Integrations
    Full REST API for real-time validation at point of entry. Native integrations available for GoHighLevel and Zapier — no custom code required.
  • 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

  • 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.
