Features and specs

What each product offers, as listed by its team.

Modular JavaScript 5 features
StealthPeek 6 features
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Questions & Answers

As answered by people managing Modular JavaScript and StealthPeek.

Who are some of the biggest customers of your product?

StealthPeek's answer:

Our users are individuals: marketers, journalists, creators, partners, and parents.

What makes your product unique?

StealthPeek's answer:

We are honest about the limits. Public accounts only, no credentials, no fake results, and we say plainly when something cannot be done, like viewing a private profile. That honesty is rare in this category.

Why should a person choose your product over its competitors?

StealthPeek's answer:

No account or login, so your name never appears in a seen list. Downloads come out in original quality with no watermark. And we keep the service maintained, because these tools break when Instagram changes its backend and most others go silent.

How would you describe the primary audience of your product?

StealthPeek's answer:

Professionals who need to see public Instagram content without being seen: marketers checking competitors, journalists verifying posts, recruiters reviewing profiles. At home, partners and parents checking what loved ones share publicly. The common thread is wanting to browse without leaving a trace.

What's the story behind your product?

StealthPeek's answer:

A small team with a background in privacy and data kept running into viewers that demanded a login or faked their results, and the honest option was missing. So we built one: public content only, no credentials, no tricks.

Which are the primary technologies used for building your product?

StealthPeek's answer:

Next.js and React on the front end, backed by our own fetching infrastructure that pulls public content so your identity stays out of the request.
