What is CADProps?
CADProps is a browser tool for opening, measuring and converting CAD and 3D files. It supports 92 extensions, including STEP, IGES, STL and common mesh formats, plus native SolidWorks, Inventor, CATIA and NX. Native formats are processed on CADProps servers rather than only inside the browser tab.\n\nEngineers, buyers and 3D-print shops use it when a supplier sends a model and they need dimensions, volume, surface area or a conversion without installing a full CAD seat. Check a known dimension before you slice or forward the file, because many STEP exports are unitless or in inches while the drawing is in millimetres.\n\nA free tier covers everyday viewing and measurement. Paid plans exist for heavier use. Ethan Tan builds CADProps.
What problem it solves
People receive STEP, IGES or native CAD from a supplier and cannot open or measure it without an expensive CAD license. CADProps lets them inspect size and volume in the browser.
What is rdyrct?
rdyrct is an open-source URL shortener and QR code platform for people who want branded links and clear campaign analytics. Create short links on your own custom domains, choose memorable slugs, and tag destinations with UTM parameters. On shared domains, slugs are random. The public QR generator lets anyone create and download plain link QR codes without an account; hosted Free plans include plain QR codes, while custom colors, dot styles, and logos are available on paid plans.
Understand how links perform with analytics by country, referrer, device, time, and UTM campaign, without storing IP addresses or tracking precise locations. Compare periods, review campaign, source, and medium rankings, explore activity patterns, and set alerts for quiet links or significant click drops. The built-in UTM builder helps keep campaign tags consistent.
Teams can organize work in shared organizations with owner, admin, member, and viewer roles. Email invitations are single-use and expire after seven days. Rename slugs with a 48-hour redirect, add aliases, or consolidate destinations that have already been shortened. Temporary anonymous links last 24 hours. For automation, use scoped organization API keys or connect an MCP client through OAuth.
The hosted Free plan includes one organization, 30 links, three teammates, seven-day analytics, API access, and MCP access. Hobby is $4 per month; Pro is $9 per month with higher limits and longer analytics history. rdyrct is MIT licensed and can also be self-hosted on Cloudflare Workers, D1, KV, and R2. Version 1.0.0 has no plan caps when billing is not configured; Cloudflare infrastructure costs still apply. Email and billing providers are optional for self-hosting, though email features such as password reset and verification require an email provider or Google sign-in.
