Revievv features and specs

  • 3D STEP/STL viewer in the browser
    Open and inspect 3D CAD files directly in your browser. No CAD license, no plugins, no desktop software required. Works on Mobile as well.
  • Pin comments directly on 3D model
    Click any point on a 3D model to pin a comment with exact visual context. No more describing "the corner on the left side."
  • PDF and image review
    Review technical drawings, schematics and images with markup tools, distance and angle measurements โ€” all in the browser.
  • Share review links
    Send a link to anyone - suppliers, clients, teammates. They can view and comment without creating an account or paying for a seat.
  • Issue tracking with severity
    Assign severity levels, set deadlines, track resolution status. Every comment becomes a trackable issue.
  • Export review as PDF
    Generate a PDF report with all comments pinned on the model or drawing. Ready to share with stakeholders or archive.
  • Wire tracing on PDF
    Click a line on an electrical schematic โ€” the system highlights the entire connected circuit through connectors and branches. One click instead of tracing by eye.

php eventloop features and specs

  • Simple and lightweight
    The library provides a minimalistic implementation of an event loop in PHP, making it easy to understand and integrate into small projects without heavy dependencies.
  • Educational value
    As a straightforward PHP event loop implementation, it serves as a great learning resource for developers wanting to understand how event loops and asynchronous programming concepts work under the hood in PHP.
  • Non-blocking I/O support
    The library enables non-blocking I/O operations in PHP, allowing developers to handle multiple tasks concurrently without relying on multi-threading, which PHP does not natively support well.
  • Timer and periodic task support
    It provides built-in support for timers and periodic tasks, enabling developers to schedule recurring operations or delayed execution within the event loop.
  • Pure PHP implementation
    The library is written in pure PHP without requiring external C extensions, making it portable and easy to install across different PHP environments without special compilation steps.

Possible disadvantages of php eventloop

  • Limited community and support
    The project has a very small community with minimal stars, forks, and contributors on GitHub, which means limited peer support, fewer bug reports, and potentially slower issue resolution.
  • Not production-ready
    Given its small scale and limited adoption, the library may not be battle-tested enough for production environments where reliability, performance, and stability are critical.
  • Limited features compared to alternatives
    More established PHP async libraries like ReactPHP, AmpPHP, and others offer far more comprehensive ecosystems with HTTP servers, database clients, and stream handling that this library lacks.
  • Performance limitations
    Being a pure PHP implementation without leveraging extensions like ev, libuv, or swoole, the event loop may suffer from performance bottlenecks compared to extension-backed alternatives when handling high concurrency.
  • Poor documentation
    The repository has minimal documentation and examples, making it difficult for new users to understand the full API, edge cases, and best practices for using the library effectively.

Analysis of php eventloop

Overall verdict

  • php-eventloop is a lightweight event loop implementation for PHP that provides a solid, minimalistic solution for developers wanting to implement asynchronous, non-blocking behavior without adopting a full framework like ReactPHP or Amp. It's good for learning purposes and simpler use cases, though it lacks the extensive ecosystem, tooling, and production hardening of more established async libraries.

  • Lightweight and simple to understand, making it easy to integrate into small projects
  • Useful for learning how event loops work under the hood in PHP
  • Minimal dependencies compared to larger async frameworks
  • Open source and available for inspection/modification on GitHub
  • Can be a good starting point for building custom async solutions

Recommended for

  • Developers learning about event-driven programming in PHP
  • Small projects needing basic async functionality without heavy dependencies
  • Educational purposes and understanding event loop internals
  • Prototyping simple non-blocking I/O operations
  • Developers who want full control over a minimal event loop implementation

Questions & Answers

As answered by people managing Revievv and php eventloop.

What makes your product unique?

Revievv's answer

Reviewers don't need a CAD license, an account, or any installed software. Just a link. Most design review tools charge per seat or require everyone to have CAD software. Revievv gives unlimited free reviewers on every plan - so your suppliers, clients and cross-functional teammates can give feedback without any barriers.

Why should a person choose your product over its competitors?

Revievv's answer

Some competitors costs six figures and takes months to deploy. Revievv starts at $0, works in 30 seconds, and does what engineering teams actually need: open a CAD file, pin comments on the 3D model, share a link, collect feedback. No procurement process, no IT department required.

How would you describe the primary audience of your product?

Revievv's answer

Mechanical and electrical engineers in teams of 5-50 people โ€” product design, manufacturing, automotive, aerospace. Engineers who send STEP files by email, mark up screenshots in PowerPoint, and lose feedback in chat threads. Also useful for engineering managers who need documented, traceable design reviews instead of meeting notes in Excel.

What's the story behind your product?

Revievv's answer

Built by an engineer with ADHD who got tired of the same broken design review process, also had problems with doing all those related topics โ€” screenshots in PowerPoint, feedback lost in email threads, "see attachment page 3 top left corner." Every CAD collaboration tool was either enterprise-priced or view-only. Revievv fills the gap: real design review with 3D markup, simple enough to start in 30 seconds, affordable enough for a small team.

Which are the primary technologies used for building your product?

Revievv's answer

Three.js for 3D rendering, OpenCascade for STEP/STL geometry processing, Next.js for the web application, and cloud infrastructure for file conversion. Everything runs in the browser โ€” no plugins or desktop installation needed.

Who are some of the biggest customers of your product?

Revievv's answer

Revievv is an early-stage product used by small and mid-size engineering teams. We're focused on onboarding our first 100 customers โ€” teams that need fast, affordable design review without enterprise overhead.
