ZipcodestackMarkdrop's answer
Markdrop combines powerful visual feedback, screen recording, and developer-ready bug reporting into a single, lightweight tool that feels invisible until you need it. Unlike bloated alternatives, Markdrop is fast, easy to integrate, and built for modern teams who care about speed and clarity with no Chrome extension or signup friction required.
Markdrop's answer
Affordable, transparent pricing: Markdrop offers all the core features at a fraction of the cost of tools like Markup.io or Pastel.
Designed for devs and designers: Every comment can include logs, screen recordings, and environment data ready for developers to act on.
No friction for users: Share a link and anyone can leave feedback. No browser extensions, no accounts, no hassle.
Fast and privacy-respecting: Lightweight script, GDPR-compliant, and zero tracking bloat.
All-in-one: Combines comments, annotations, bug reporting, and async video so teams donโt need 3 different tools.
Markdrop's answer
Markdrop is built for:
Founders and indie builders who want fast feedback without complex tools
Designers and PMs collecting client or stakeholder feedback
Developers who want bug reports with context, not vague screenshots
Agencies delivering websites and apps that need client review In short, itโs for lean product teams who value clarity and speed.
Markdrop's answer
Markdrop was born out of frustration. As a solo founder building multiple products, I (Manuel) kept running into the same feedback pain, long email chains, vague bug reports, and overpriced tools that did too much or too little. So I built what I needed: a clean, no-fuss tool to drop comments directly on a site, see what users saw, and get back to shipping.

Zipcodestack - Free Zip Code API and Postal Code Validation. Ten thousand free requests/month. - Source: dev.to / over 2 years ago
I have seen this request pop up quite a few times. I did a quick search for free APIs of zipcode lookups. This one, named "zipcodestack" (I'm not in any way tied to, endorsing, or promoting them) seemed like a pretty good resource with up to 10,000 free lookups each month. So, I wrapped a quick script around it and made it a custom sheets function called GET_CITY:. Source: about 3 years ago
