Analysis

Mello.tools
ShellNewHandler

Overall verdict

  • Mello.tools appears to be a useful collection of free online utilities, though as with any lesser-known tool site you should evaluate it based on your specific needs and always exercise caution with sensitive data.

Why this product is good

  • Offers a convenient set of online tools accessible directly from your browser with no installation required
  • Typically free to use, which lowers the barrier to entry for casual or one-off tasks
  • Web-based tools can be handy for quick conversions, formatting, or calculations on the go
  • Cross-platform accessibility means it works on most devices with a modern browser

Recommended for

  • Users who need quick, occasional access to online utilities without installing software
  • Developers or students looking for lightweight browser-based helper tools
  • People handling non-sensitive data who want fast, no-cost solutions
  • Anyone wanting to try out a tool before committing to a paid or dedicated alternative

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

Questions & Answers

As answered by people managing Mello.tools and ShellNewHandler.

Why should a person choose your product over its competitors?

Mello.tools's answer

Most "free online tool" sites send your input to a server you don't operate. For utilities you reach for daily — JWT decoders, image compressors, PDF mergers, password generators — that means handing potentially sensitive data to a third party you have no agreement with. Mello solves this architecturally: the site is statically generated, there are no API routes, and the only thing the server returns is HTML and JavaScript. If your input matters at all, that's the difference.

How would you describe the primary audience of your product?

Mello.tools's answer

Developers, designers, small-business operators, and knowledge workers — anyone who reaches for a "free online tool" several times a week. The privacy-first design especially fits people working with sensitive material (auth tokens, scanned IDs, financial data, unannounced creative assets) and people on slow or metered connections where avoiding uploads matters in practice.

What's the story behind your product?

Mello.tools's answer

Mello started from a recurring annoyance: needing to do something quick — decode a JWT, compress a photo, format a JSON payload — and realizing the easiest path was to paste sensitive data into a free site I had no relationship with. The "decoded client-side" claims in small text were untestable from outside. Browser-only seemed like the obvious right answer for these kinds of utilities, so I built it that way from the start. Mello shipped in May 2026 with 122 tools across 10 categories.

Which are the primary technologies used for building your product?

Mello.tools's answer

Next.js 15 (App Router) with full static export, React 19, TypeScript, and Tailwind CSS v4. Tool implementations use native browser APIs (Canvas, Web Crypto, FileReader, DOMParser) where possible, with carefully chosen JS libraries for the rest: pdf-lib and pdf.js for PDF handling, libheif compiled to WebAssembly for HEIC decoding, exifr for image metadata, marked and turndown for Markdown conversion, sql-formatter for SQL. Hosted on Cloudflare Pages as a fully static site.

What makes your product unique?

Mello.tools's answer

Mello is the only utility-tools directory at this scale built around a strict no-server-processing rule. Every one of its 122 tools runs as JavaScript in your browser — no uploads, no accounts, your inputs never leave the page. JWTs, photos with embedded GPS coordinates, contract PDFs, production data: none of it ever leaves your machine, because there is no server endpoint that could see it.

  • 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
