Cachely is the managed self-hosted remote cache for Nx and Turborepo - the cache backend you'd otherwise build and run yourself, hosted for you on Cloudflare's edge (R2). It's a drop-in replacement for a DIY @nx/s3-cache / S3 bucket setup: point your build tool at Cachely with a token and two environment variables, and share build cache across CI and every developer's laptop.

Unlike a self-hosted cache, Cachely enforces read-only tokens at the API, so pull-request and fork builds can read but never write - closing the Nx cache-poisoning attack (CVE-2025-36852). It adds ROI reporting (the real build minutes and dollars the cache saved), per-tool insights, and build-optimization suggestions on top.

Pricing is a flat per-workspace subscription with no per-seat fees - add every developer, bot, and CI actor without watching the bill. Cachely never stores your source code; it caches only task outputs and their content hashes. Nx and Turborepo today; Bazel on the roadmap.

  • Ease of Integration
    The library is designed to be easily integrated into web applications, requiring minimal setup and enabling quick implementation of eye-tracking features.
  • No Special Hardware Required
    WebGazer.js uses a web camera to perform eye-tracking, eliminating the need for specialized hardware, which makes it accessible to a broad audience.
  • Real-time Tracking
    The library provides real-time gaze tracking, making it suitable for interactive applications requiring immediate feedback.
  • Cross-Platform Compatibility
    As a JavaScript library, WebGazer.js works across different browsers and platforms, increasing its usability in diverse environments.

Possible disadvantages of WebGazer.js

  • Accuracy Limitations
    The accuracy of WebGazer.js may not match that of dedicated eye-tracking hardware, which can limit its use in precise applications.
  • Environmental Dependency
    Lighting and camera quality can affect the performance of WebGazer.js, posing challenges in uncontrolled environments.
  • Browser Performance Variability
    The performance and accuracy of the library might vary between different browsers due to discrepancies in camera access and processing capabilities.
  • Privacy Concerns
    Using a webcam raises privacy issues, as it involves capturing video data from users, which may require clear consent and data handling policies.
  • Limited Functionality
    While useful for basic eye-tracking, WebGazer.js might lack the advanced features provided by specialized eye-tracking software or libraries.

Cachely.dev features and specs

  • Simplified Caching Setup
    Cachely.dev likely offers an easy-to-integrate caching layer that reduces the complexity of manually configuring caching infrastructure, allowing developers to implement caching with minimal setup time.
  • Performance Improvement
    By providing a dedicated caching solution, Cachely.dev can help reduce latency and improve application response times, especially for frequently accessed data or API responses.
  • Developer-Focused Design
    The .dev domain and branding suggest the product is tailored specifically for developers, potentially offering clean APIs, SDKs, and documentation that fit into modern development workflows.
  • Scalability
    As a specialized caching service, it may be built to handle scaling automatically, removing the burden of managing cache infrastructure as traffic grows.
  • Reduced Backend Load
    Effective caching can significantly reduce the load on primary databases and backend services, potentially lowering infrastructure costs and improving overall system reliability.

  • Building a realtime eye tracking experience with Supabase and WebGazer.js
    I had ran into WebGazer.js a while back when I first had the idea for this project. It's a very interesting project and works suprisingly well! - Source: dev.to / over 1 year ago
  • Any way to detect a hand for touchless navigation?
    You could use something like https://webgazer.cs.brown.edu/ for reference, or tensorflow.js. Source: almost 4 years ago
  • A Drawing I've been working on since I finished the game.
    If you are looking for some extra ideas... Mmm... If I were to make something like this, I would display it in a webapp with a simple eye tracking system (like this one, for example) so that, when it doesn't detect anyone looking towards the screen, it automatically changes the background. It requires some work and coding experience, so I am not expecting anyone to actually realize it, but... Hey! If someone... Source: almost 4 years ago
  • Controller for pain-free reviewing in MedSchool (Mac, iPad)
    Ankimote developer here. I was thinking about writing something to control Anki using this gaze tracking library, but I came to realize it would be slower than finger movements since you'd need to keep your gaze in an area for a second or two to avoid false positives. It also takes a good deal of effort to consciously focus your eyes at a small area of a screen, which would probably distract the user from thinking... Source: about 5 years ago
  • Webcam and browser eyetracking libraries?
    Do you know about JS libraries which can be used in the browser to perform eyetracking (gaze prediction) using a webcam? I was giving a look at the WebGazer JS but wanted to know if there are some other alternatives out there. Source: about 5 years ago
