Lightweight schema validation

TypeScript-first design

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

ShellNewHandler

IsValid.dev

Overall verdict

ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
Lightweight and free, without bundled bloatware typical of some other free utilities
Simple and focused in scope, making it easy to understand for its specific purpose
Open distribution via SourceForge allows transparency and no-cost access

Recommended for

Power users who want to declutter or customize the Windows New context menu
IT administrators managing standardized desktop environments across multiple machines
Users comfortable with older utility-style tools and Windows registry-related tweaks
Not recommended for casual users seeking modern, actively supported software with regular updates

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 ShellNewHandler and IsValid.dev.

What makes your product unique?

IsValid.dev's answer:

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.

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 — 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

I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
