No analysis of Linewhale yet.

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 Linewhale and ShellNewHandler.

What makes your product unique?

Linewhale's answer

Linewhale puts sportsbook odds and prediction-market prices (Kalshi and Polymarket) on the same screen, so you can see where they disagree. Most odds tools only cover sportsbooks. Linewhale also gives away a lot without a paywall: live odds comparison, line movement charts, and a full set of betting calculators are free with no account. Only the advanced finders (arbitrage, positive EV, middles and steam moves) are behind premium.

We also are the only odds comparison that shows you positive EV territory per betting market all for free.

Why should a person choose your product over its competitors?

Linewhale's answer

Price and simplicity. Competitors like OddsJam and Unabated are powerful, but their premium plans can cost well over $100 a month. Linewhale's Arbitrage Finder, Positive EV Finder, Middle Finder and Steam Moves cost $25/month, or $20/month billed annually. The interface is built to be fast and clean, so a newer bettor can learn to shop for the best line without feeling overwhelmed. Linewhale is independent and isn't owned by a sportsbook. We also provide tons of free resources where at a glance you can get a good betting edge all for free.

How would you describe the primary audience of your product?

Linewhale's answer

Two groups. The first is recreational bettors who want to stop leaving money on the table by checking every book for the best price before they bet. The second is advantage bettors (people hunting arbitrage, positive-EV and middle opportunities) who need fast, reliable data without paying enterprise-level prices. Most users bet on the NFL, NBA, MLB, NHL and UFC across several sportsbook accounts.

What's the story behind your product?

Linewhale's answer

Linewhale started because I was betting across several sportsbooks and got tired of opening five apps to find the best line / the existing tools were too expensive for what I needed. I built the first version to compare odds for myself, then added the calculators and finders I wished existed. It's built and run independently, with no sportsbook ownership, and every dollar of revenue goes back into making the product better.

Which are the primary technologies used for building your product?

Linewhale's answer

Next.js and Node.js

Who are some of the biggest customers of your product?

Linewhale's answer

Linewhale is used by thousands of individual bettors every month, from casual bettors learning to line shop to advantage bettors running arbitrage and +EV strategies. We host odds from large name bookmakers and exchanges like: - Kalshi - Polymarket - Novig - Draftkings - Fanduel - BetMGM - Pinnacle - Smarkets - Matchbook - ESPN Bet - Caesars - Fanatics and many many more

  • 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
