mesu.ro is a fully-featured, browser-based measurement tool for images and PDF files. No upload, no account, no installation required โ everything runs locally in your browser. Measurement tools: Distance, diameter, angle (works without scale), area, path/perimeter, and text annotations. All measurements are displayed in real-world units with pixel fallback when no scale is set. Scale calibration: Draw a line over any known reference, enter its real-world value and unit (mm, cm, inches, feet, or any custom unit). The last used value is remembered across sessions. PDF support: Load PDF files directly โ single-page PDFs open instantly, multi-page PDFs show a high-resolution page picker. Pages are rendered at ~430 dpi for precise measurement of technical drawings. Edge snap: Toggle sub-pixel edge detection (full Canny pipeline with Non-Maximum Suppression). The cursor locks onto detected contours with subpixel precision โ ideal for engineering drawings and schematics. Perspective correction (Rectify): Place 4 corner points to correct perspective distortion before measuring. True homography with automatic aspect ratio recovery. Pan & zoom: Mouse wheel zoom up to 20ร, click-drag pan, keyboard arrow navigation. A magnifier overlay shows a 5ร live zoom around the cursor for precise point placement. Export: Annotated image (PNG, JPG, WebP), CSV data table, PDF measurement report with scale info and measurement table. Save/load full project files (.mesuro) to resume work later. Interface: 5 languages (EN, FR, ES, DE, IT), dark theme, keyboard shortcuts for all tools, undo (50 levels), draggable measurement labels.

Mesu.ro's answer:
mesu.ro is the only tool that combines: Browser-based, zero friction โ open URL, drop image, measure. No account, no upload, no install PDF import with page selection โ direct load, rendered at 430dpi, no conversion step needed Edge snap โ Canny edge detection with NMS and subpixel interpolation, running entirely client-side in JS Perspective correction โ full homography, not just a crop or rotate Complete measurement suite โ distance, diameter, angle, area, perimeter, notes, all calibrated to real-world units Privacy by design โ images never leave the device, no server, no telemetry on the image data Multilingual โ 5 languages out of the box
Mesu.ro's answer:
mesu.ro wins on speed of access and zero friction. No download, no signup, no payment, no learning curve. For anyone who measures images occasionally โ checking a dimension on a photo, measuring a PDF plan, verifying a part from a SEM image โ the barrier to use is essentially zero.
Mesu.ro's answer:
Engineers, technicians, and researchers who receive images or PDF drawings and need to extract real dimensions from them. PCB designers checking component placement from a photo. Mechanical engineers measuring a part from a SEM or microscope image. Architects verifying dimensions on a scanned floor plan. They know what a scale is, they measure in mm, and they need a result fast without opening a dedicated software suite.
Mesu.ro's answer:
mesu.ro was born out of frustration. As an engineer, I kept needing to measure things in images โ parts, drawings, microscope photos. Every existing tool was either a $500 desktop app, a complex scientific suite, or a basic online tool that only did distance. So I built a single HTML file that did exactly what I needed. No server, no upload, no account. Just drop an image and measure. I added PDF support, edge snap, perspective correction, multilingual interface. At some point I realized I'd accidentally built the tool that should have existed all along. I put it online. A stranger sent $5 on Ko-fi three days later. That was enough.
Mesu.ro's answer:
A single HTML file. That's the whole stack โ no framework, no build tool, no dependencies bundled locally. Everything runs in the browser. The technologies inside that file: Vanilla JavaScript โ all measurement logic, canvas rendering, pan/zoom, undo, project save/load HTML5 Canvas API โ drawing the image, measurements, magnifier overlay, snap indicator PDF.js (Mozilla, via CDN) โ PDF parsing and high-resolution page rasterization jsPDF (via CDN) โ PDF report generation client-side Canny edge detection โ implemented from scratch in JS (Gaussian blur, Sobel, NMS, hysteresis, subpixel interpolation) Umami Analytics โ privacy-friendly, self-hosted compatible, no cookies Formspree โ feedback form backend, zero server required GitHub Pages โ hosting, free, zero infrastructure to manage
Based on our record, API Platform seems to be more popular. It has been mentiond 39 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Another difference is that in .NET Core, we can integrate with OpenAPI out of the box (it is part of the framework), while in Symfony, an API-based application with OpenAPI features is only available using a third-party toolโthe API Platform. - Source: dev.to / about 2 years ago
API Platform is a great tool for rapid API development, but it has a lot of not-so-well-documented features which can sometimes lead to confusion. Playing around with a new project of mine I've stumbled into one: tests were failing for my validation assertions of endpoints' responses! - Source: dev.to / about 2 years ago
Technically API Platform is not part of Symfony. Although, they are both French. ๐. - Source: dev.to / over 2 years ago
Probably API-platform. The website is down at the moment, but: https://github.com/api-platform/api-platform It's Symfony based (and plays nice in that ecosystem), also allows you to describe entities via Schema org vocab, has a client generator, and comes with docker-compose and helm charts. I've used it extensively to build various headless services. It's really easy to expose annotated Doctrine entities. Source: about 3 years ago
API Platform is a framework for API-first projects, built on top of Symfony components. Let's see how to create a minimal and lightweight starter project in just 5 minutes! - Source: dev.to / about 3 years ago
