Websites using Formvalidation

Okay, let s break down Formvalidation, covering its overview, revenue (estimated), alternatives, pricing, and customer care details.

Formvalidation Overview

Formvalidation is a JavaScript library designed to help developers create robust and user-friendly form validation experiences. It goes beyond simple HTML5 validation, offering a wide range of features to handle complex validation scenarios. Here s a breakdown of its key aspects:

• Purpose: To simplify and enhance the process of validating user input in web forms. It aims to provide a consistent and reliable way to check for errors, display informative messages, and prevent invalid data from being submitted.
• Key Features:
  • Comprehensive Validation Rules: Supports a wide range of built-in rules (e.g., required fields, email format, number ranges, pattern matching) and allows for custom rules.
  • Real-Time Validation: Validates input as the user types, providing immediate feedback.
  • Clear Error Messages: Displays user-friendly and configurable error messages.
  • Cross-Browser Compatibility: Works reliably across different browsers.
  • Framework Integration: Can be integrated with popular JavaScript frameworks (e.g., jQuery, Bootstrap, Foundation, Pure.css).
  • Highly Customizable: Allows for extensive customization of styles, messages, and behaviors.
  • AJAX Validation: Supports asynchronous validation (e.g., checking if a username is already taken).
  • Internationalization (i18n): Provides support for different languages.
• Target Audience: Web developers who need a flexible and powerful solution for handling form validation in their projects, ranging from small static sites to large dynamic web applications.

Estimated Revenue

It s difficult to provide exact revenue figures for Formvalidation as it s a primarily open-source project with a commercial license option. Here s an estimation:

• Commercial License Revenue: Formvalidation offers commercial licenses for projects requiring additional support or wanting to use the software without the restrictions of the GPL license. This is likely where a majority of its revenue would be generated. Given the active user base and long history, they likely generate low to mid-six figures annually.
• Consulting/Support: While not heavily advertised, they may also offer paid consulting and priority support for enterprise clients. This would supplement the commercial license income.

It s important to note that Formvalidation s core value proposition is in the free and open source version. The revenue streams are generally a secondary or optional part of their model.

Alternatives to Formvalidation

There are many JavaScript form validation libraries available. Here are some of the prominent alternatives:

1. HTML5 Built-in Validation:

   • Pros: Simple and readily available; No external library is required.
   • Cons: Limited flexibility, customization, and browser compatibility.
   • Use Cases: Basic, non-complex forms.

2. jQuery Validation Plugin:

   • Pros: Well-established, easy to use, and good community support.
   • Cons: Requires jQuery, may be less flexible for complex scenarios.
   • Use Cases: Projects already using jQuery.

3. Parsley.js:

   • Pros: Simple to use, focuses on HTML5 data attributes for rules, good documentation.
   • Cons: Not as flexible and extensible as Formvalidation.
   • Use Cases: Projects with simpler validation requirements, HTML-centric approach.

4. Vee-Validate:

   • Pros: Framework-agnostic (works with Vue, React, and more), component-based, highly customizable.
   • Cons: Might be overkill for non-SPA projects.
   • Use Cases: SPA (Single Page Application) projects using modern frameworks.

5. Zod:

   • Pros: Type-safe schema validation, works with TypeScript, good for API input validation too.
   • Cons: Might require a learning curve.
   • Use Cases: Projects with an emphasis on typed interfaces.

6. React Hook Form:

   • Cons: Limited scope. Requires React usage.
   • Use Cases: React projects, focusing on performance.

Pricing

Formvalidation has different pricing options based on project needs:

• Free and Open Source (GPL v3):

  • License: GPL v3.
  • Cost: Free for personal and open-source projects.
  • Limitations: GPL license means that any project using it must also be licensed under GPL if the source code is distributed. This restricts use in closed-source commercial software.

• Commercial License:

  • License: Proprietary, allows use in closed-source commercial software.
  • Cost: Varies based on project scope and number of developers. The website provides a contact form to request a quote. Prices are usually on a per-site basis.
  • Benefits:
    • Can use in private, closed-source projects
    • Guaranteed support
    • Freedom from GPL s requirements
    • Possibility for enterprise level features and assistance

Customer Care Details

• Documentation: Comprehensive and well-maintained documentation is the main source of information.
• Online Community: There is an active community through GitHub where you can ask questions, report bugs and contribute to the project
• Contact Form: A contact form is available on the website for questions related to commercial licenses, priority support, and sales inquiries.
• Commercial Support: For commercial license holders, the vendor offers direct support, usually through email.

Summary

Formvalidation is a powerful and customizable library for handling complex form validation needs. While the free version suits many projects, the commercial license enables commercial closed source projects to use it, with the additional benefit of customer support and assistance. It’s a solid solution for those who value a flexible and robust tool, but it s essential to consider the alternatives based on project requirements and frameworks.
