Features and specs

What each product offers, as listed by its team.

IsValid.dev 5 features
Things 7 features
  • 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.
  • User Experience
    Things is known for its clean, intuitive, and beautifully designed user interface, making it easy to use.
  • Integration with Apple Ecosystem
    Seamlessly integrates with macOS and iOS devices, offering features like Handoff and deep Apple Calendar integration.
  • Powerful Task Management
    Supports projects, areas, headings, and tags, providing a robust system for managing complex tasks and workflows.
  • Quick Entry
    Provides a quick entry function allowing users to capture tasks efficiently, which can later be categorized and detailed.
  • Updates and Support
    Regularly updated with new features and enhancements, backed by reliable customer support.
  • Keyboard Shortcuts
    Offers extensive keyboard shortcuts for power users to navigate and manage tasks quickly.
  • Natural Language Processing
    Allows users to input tasks using natural language, which is then intelligently parsed and scheduled.

Possible disadvantages

  • Cost
    Things requires a one-time purchase for each platform (macOS, iOS), making it relatively expensive compared to some subscription-based competitors.
  • Platform Limitation
    Only available on Apple devices (macOS and iOS), making it inaccessible for users on Windows, Android, or other platforms.
  • No Collaboration Features
    Lacks built-in collaboration tools, which can be a drawback for teams looking to share and manage tasks collectively.
  • Learning Curve for Advanced Features
    While the basic interface is user-friendly, fully utilizing advanced features can require time and a deeper understanding.
  • Limited Automation
    Offers fewer automation options and integrations compared to some competitors like Todoist or Microsoft To Do.

Questions & Answers

As answered by people managing IsValid.dev and Things.

IsValid offers 70+ validators in a single API — 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.

What's the story behind your product?
