Features and specs

What each product offers, as listed by its team.

Node.js 6 features
Diopter 5 features
  • Asynchronous and Event-Driven
    Node.js uses an asynchronous, non-blocking, and event-driven I/O model, making it efficient and scalable for handling multiple simultaneous connections.
  • JavaScript Everywhere
    Developers can use JavaScript for both client-side and server-side programming, providing a unified language environment and better synergy between front-end and back-end development.
  • Large Community and NPM
    Node.js has a vibrant community and a rich ecosystem with the Node Package Manager (NPM), which offers thousands of open-source libraries and tools that can be integrated easily into projects.
  • High Performance
    Built on the V8 JavaScript engine from Google, Node.js translates JavaScript directly into native machine code, which increases performance and speed.
  • Scalability
    Designed with microservices and scalability in mind, Node.js enables easy horizontal scaling across multiple servers.
  • JSON Support
    Node.js seamlessly handles JSON, which is a common format for API responses, making it an excellent choice for building RESTful APIs and data-intensive real-time applications.

Possible disadvantages

  • Callback Hell
    The reliance on callbacks to manage asynchronous operations can lead to deeply nested and difficult-to-read code, commonly referred to as 'Callback Hell'.
  • Not Suitable for CPU-Intensive Tasks
    Node.js is optimized for I/O operations and can become inefficient for CPU-intensive tasks, slowing down overall performance due to its single-threaded event loop.
  • Immaturity of Tools
    Compared to more established technologies, some Node.js libraries and tools still lack maturity and comprehensive documentation, which can be challenging for developers.
  • Callback and Promise Overheads
    Managing asynchronous operations using callbacks or promises can lead to additional complexity and overhead, impacting maintainability and performance if not handled correctly.
  • Fragmented Ecosystem
    The fast-paced evolution of Node.js and its ecosystem can lead to fragmentation, with numerous versions and libraries that may not always be compatible with each other.
  • Security Issues
    The extensive use of third-party libraries via NPM can introduce security vulnerabilities if not properly managed and updated, making applications more susceptible to attacks.
  • AI-Powered Code Review
    Diopter leverages artificial intelligence to automate and enhance code review processes, potentially catching issues faster than manual review alone.
  • Integration Capabilities
    The tool is designed to integrate with existing development workflows and version control systems, making it easier to adopt without disrupting current processes.
  • Time Efficiency
    By automating parts of the code review process, Diopter can help development teams save time and accelerate their software delivery cycles.
  • Consistency in Reviews
    AI-driven reviews can provide consistent feedback based on predefined rules and patterns, reducing variability that might occur with different human reviewers.
  • Scalability
    As an AI-based solution, Diopter can potentially scale to handle large codebases and high volumes of pull requests more efficiently than manual review processes.

Questions & Answers

As answered by people managing Node.js and Diopter.

What makes your product unique?

Diopter's answer:

Diopter scores the live call, not a file after the fact. Most detection tools ask you to upload media and wait for a verdict. Diopter runs alongside a Zoom, Microsoft Teams, Google Meet or Webex call and scores every participant continuously for the full length of the call, including someone who is not speaking.

It also combines four signals rather than one. Video deepfake detection, audio deepfake detection, identity and payment verification, and policy alignment resolve into a single recommended action, so a security or finance team gets one decision rather than four dashboards.

The verdicts are deliberately honest. Bands are AI, mixed, clean and inconclusive, each with a confidence level rather than a flat yes or no. If a call could not be fully checked, Diopter reports that rather than defaulting to clean. It does not identify who is speaking, uses no voiceprints or enrollment, and never treats accent, region or language as a signal.

Why should a person choose your product over its competitors?

Diopter's answer:

Because the attack happens on the call, and that is where Diopter works.

Identity verification tools check a person once, usually at onboarding or account recovery. That does nothing for a wire approval call three months later where the person on screen is a deepfake. Single-frame or file-based detectors judge a moment of media rather than the conversation shaping the ask.

Diopter runs for the whole call and scores every participant continuously, on Zoom, Microsoft Teams, Google Meet and Webex, and on VoIP and conference phone calls through Zoom Phone, Teams Phone, RingCentral and Dialpad. It combines synthetic media detection with identity and payment verification and policy alignment, then returns one recommended action.

It is also straightforward to deploy and clear about its limits. No caller-side install, works with a meeting bot or bot-free, on-prem and hybrid supported, configurable retention including zero data retention, and rollout through existing MDM such as Intune and Jamf. SOC 2 Type II in progress.

How would you describe the primary audience of your product?

Diopter's answer:

Security and fraud teams at organisations where a phone or video call can move money, grant access or hire someone.

The people who buy and run it are CISOs and security operations, fraud operations, and IT. The people it protects usually sit elsewhere in the business: finance and treasury staff approving wires, accounts payable teams handling vendor payment changes, recruiters and hiring managers interviewing candidates, executive assistants fielding urgent requests, and IT help desk agents resetting credentials.

The common thread is a live conversation where someone is asking for something consequential and the only proof of who they are is their face or their voice.

What's the story behind your product?

Diopter's answer:

Diopter was founded in April 2026 by Rohan Gupta and Jeremy Pippin, after they watched generative AI move from productivity use cases into impersonation, fraud and social engineering.

Both came from QuillBot, where Rohan was founder and CEO of a generative AI company with more than 35 million monthly users, and Jeremy was VP of Product, having previously held the same role at FanDuel. They had spent years on the building side of generative AI and could see how cheap and scalable the attack had become while defence stayed expensive and manual.

The belief that shaped the product is that fraud is rarely detectable from a single frame or voice sample. It unfolds across a conversation, so the arc is the unit of analysis: authority, urgency, isolation, escalation and the ask, scored continuously through a live call.

The company is based in Chicago, Illinois.
