Analysis

An editorial look at what each product does well and who it suits.

ShellNewHandler
SubnetLens

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

  • I don't have verified information about SubnetLens (subnetlens.com) in my knowledge base, so I can't confirm its features, quality, or reputation with confidence. It may be a newer or niche tool that isn't well-documented in publicly available sources I was trained on. I'd recommend checking recent user reviews, testing any free tier or trial, and verifying claims directly on their website before committing.

Why this product is good

  • Insufficient verified data available to confirm specific strengths or unique selling points of this product
  • Unable to validate claims about accuracy, pricing, or performance without firsthand or well-documented third-party sources
  • Recommend checking current reviews on platforms like Trustpilot, G2, or Reddit for real user experiences
  • Look for transparency about the company, its team, and how the tool sources or processes network/subnet data

Recommended for

  • Users who want to independently verify tool credibility before adoption
  • Network administrators or IT professionals researching subnet calculation or management tools who should compare multiple options
  • Anyone willing to test a free trial or demo version before making a purchasing decision

Questions & Answers

As answered by people managing ShellNewHandler and SubnetLens.

Who are some of the biggest customers of your product?

SubnetLens's answer:

System admins, Network or IT Professionas

Which are the primary technologies used for building your product?

SubnetLens's answer:

  • Electron + React — the desktop app
  • Node.js — the scanning engine and 26 diagnostic tools
  • Vite + Tailwind CSS — the UI
  • vis-network — the interactive topology map
  • A privacy-first Cloudflare Workers backend for licensing (no user data stored)

What's the story behind your product?

SubnetLens's answer:

SubnetLens started from a simple frustration: the free network scanners are basic and barely maintained, while the capable tools are either cloud subscriptions or cost thousands a year per site. There wasn't a modern, local-first option that just told you what's on your network and watched it for changes — without sending your data to someone else's cloud. So we built one: a fast, visual Windows scanner that names every device, tracks how your network changes over time, and keeps 100% of the data on your machine. One-time price, no telemetry.

How would you describe the primary audience of your product?

SubnetLens's answer:

  • SMB and solo IT admins managing a network without a big budget
  • Sysadmins, MSPs and IT contractors doing discovery and audits
  • Home-lab and self-hosting enthusiasts who want to see and monitor every device Anyone who finds Advanced IP Scanner too basic but won't pay $1,000/year for an enterprise SaaS tool.

Why should a person choose your product over its competitors?

SubnetLens's answer:

  • vs Advanced IP Scanner / Angry IP Scanner — free but basic and barely updated. SubnetLens adds live monitoring, port history, risk scoring, a credential vault and a modern UI.
  • vs Fing Desktop — no subscription. SubnetLens is one-time $79 and tracks ports per device, not just devices.
  • vs Auvik / Domotz / Lansweeper — no cloud dependency and no $500–1,000/year/site bill. Your data stays local and you pay once. More capable than the free tools, far cheaper than the enterprise ones, and everything stays on your machine.

What makes your product unique?

SubnetLens's answer:

A few things no other consumer-priced scanner combines: - It names and identifies every device — recognizes 1,451 device types by hostname, so you see "Canon G5000 printer" or "Synology NAS," not just an IP. - Per-device port history — records the exact moment a new service opens on a device, so you catch a server that suddenly started running RDP. Enterprise tools charge thousands a year for this. - Live Mode — continuous mDNS/SSDP listening catches devices the moment they appear, between scans. - 100% local — no cloud, no telemetry, no account. Your scan data never leaves your machine. - One one-time price, with an encrypted credential vault, 26 IT tools, scheduling, SNMP, IPAM and a Prometheus endpoint all bundled in.

  • 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
