Features and specs

What each product offers, as listed by its team.

Foam 6 features
CipherKit.app 5 features
  • Open Source
    Foam is an open-source tool, which means it is free to use and allows for community-driven development and contributions. Users can modify the source code to fit their specific needs.
  • Markdown Support
    Foam uses Markdown, a lightweight and easy-to-read syntax, making it simple to create and manage notes. This also allows for easy integration with other Markdown-based tools and platforms.
  • Integration with Visual Studio Code
    Foam is designed to work seamlessly with Visual Studio Code (VS Code). This provides users with a powerful and familiar text editor environment, complete with extensions and customization options.
  • Graph View
    Foam includes a graph visualization feature that helps users see and navigate the relationships between their notes, making it easier to understand and manage complex information.
  • Bidirectional Links
    Foam supports bidirectional links, allowing users to create connections between notes in both directions. This enhances the note-taking experience by enabling a more interconnected and dynamic information structure.
  • Community and Documentation
    Foam has a growing community of users and contributors, as well as comprehensive documentation. This support network helps users troubleshoot issues, share tips, and improve their knowledge of the tool.

Possible disadvantages

  • Limited to VS Code
    Foam relies on Visual Studio Code as its primary environment. Users who prefer different text editors or platforms might find this limitation restrictive and less convenient.
  • Learning Curve
    Although Foam leverages Markdown, users may still face a learning curve, especially if they are not familiar with VS Code or the specific features and extensions required to maximize Foam's capabilities.
  • Performance with Large Datasets
    Foam can struggle with performance issues when handling large datasets or a high number of notes. This can lead to slow response times and inefficient workflows.
  • Limited Mobile Support
    Foam is primarily designed for desktop use within VS Code, which means that mobile support is limited. Users looking for a seamless cross-platform experience might find this aspect lacking.
  • Customization Complexity
    While Foam offers a high degree of customization, setting up and configuring the tool to meet personal preferences and workflows can be complex and time-consuming for some users.
  • Privacy-focused
    CipherKit is designed as a local-first encryption toolkit, meaning your data stays on your device and is not uploaded to external servers, which is ideal for users who prioritize privacy and data security.
  • Multiple encryption tools in one app
    CipherKit bundles several cryptographic utilities together—such as encryption, decryption, hashing, and encoding—into a single convenient application, reducing the need for multiple separate tools.
  • User-friendly interface
    The app provides a clean and intuitive interface that makes complex cryptographic operations accessible to users who may not have deep technical expertise in encryption and security.
  • Offline functionality
    Since CipherKit operates locally on the device, it can function without an internet connection, making it reliable for use in situations where connectivity is limited or when users want to ensure no data leaves their machine.
  • macOS native experience
    CipherKit is built as a native macOS app, which means it integrates well with the Apple ecosystem, offering smooth performance and a familiar look and feel for Mac users.

Questions & Answers

As answered by people managing Foam and CipherKit.app.

What makes your product unique?

CipherKit.app's answer:

Most legacy developer tools send your sensitive JSON payloads, JWTs, and encryption keys to a backend server, often logging data or running heavy ad-tracking scripts.

CipherKit is built differently. It is an enterprise-safe utility suite engineered for absolute privacy:

  • 100% Client-Side: All 77+ tools process your data locally right inside your browser. Your proprietary data never leaves your machine.
  • Zero Tracking: There are no databases, no server uploads, and absolutely no tracking scripts or ads.
  • High Performance: Engineered with Vanilla JS and Web Workers, ensuring that even massive payloads won't freeze your UI.
  • Enterprise Ready: Perfectly safe for developers working in strict corporate, healthcare, or fintech environments.

Why should a person choose your product over its competitors?

CipherKit.app's answer:

Developers should choose CipherKit over legacy competitors because it finally solves the "security versus convenience" dilemma.

  • Absolute Data Privacy: Popular online formatters often send your data to remote servers for processing. CipherKit executes everything locally, meaning you can safely format proprietary company code or API keys without risking a data leak.
  • No Installation Needed: Desktop-based alternatives require downloads and IT admin privileges to install. CipherKit gives you native desktop-level power instantly right in your browser.
  • Ad-Free Experience: Most legacy web tools are cluttered with intrusive banner ads, pop-ups, and trackers. CipherKit offers a clean, premium, dark-mode UI designed for focused work.
  • Lightning Fast: By utilizing Web Workers, heavy tasks (like hashing large files or diffing massive JSON blocks) happen in the background without freezing your browser tab.

How would you describe the primary audience of your product?

CipherKit.app's answer:

The primary audience is software engineers, DevOps professionals, and security analysts. It is specifically designed for developers working in strict enterprise environments—like fintech, healthcare, and large corporate networks—where corporate firewalls block legacy online tools, and Infosec policies strictly prohibit pasting proprietary API payloads into external websites.

What's the story behind your product?

CipherKit.app's answer:

As a Software Engineer working in fintech, I constantly needed to debug API payloads, format JSON, and decode JWTs. However, I quickly realized that pasting sensitive company data into random, ad-heavy online formatters was a massive security violation. I searched for a clean, privacy-first alternative but couldn't find one that didn't track data or send it to a backend server. So, I decided to build CipherKit myself—a tool that the strictest Infosec teams would actually approve for their developers to use.

Which are the primary technologies used for building your product?

CipherKit.app's answer:

To guarantee absolute data privacy and offline capability, CipherKit is built entirely without a backend. The primary technologies include:

  • Vanilla JavaScript: Keeps the application lightweight, incredibly fast, and free of unnecessary framework dependencies.
  • Web Workers: Offloads heavy cryptographic operations (like AES encryption) and massive text diffs from the main thread, ensuring the UI remains buttery smooth even with huge payloads.
  • Native Browser APIs: All formatting, decoding, and hashing happens securely utilizing the browser's local environment, meaning zero server uploads.

Who are some of the biggest customers of your product?

CipherKit.app's answer:

CipherKit is a free, open-source tool built for the community, rather than a paid B2B enterprise product. Its "customers" are individual software engineers, security analysts, and IT professionals working inside strict corporate networks who rely on it daily as their safe, locally-hosted utility suite.
