Markdrop'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.
Markdrop's answer:
Which are the primary technologies used for building your product?
Frontend: Svelte 5 Backend: Cloudflare Workers, D1, and Durable Objects Database: Wrangler DB (D1) DevOps/Infra: Cloudflare Pages + R2 for static assets and file storage
Markdrop's answer:
Indie founders using Markdrop to launch and iterate faster
Agencies working with clients.
YC applicants using it to get fast design review
No-code builders collecting client feedback inside Webflow
Internal product teams replacing Slack screenshots with structured feedback

To begin, you can start creating your own react app using the command line or can directly go to CodeSandbox if you want to skip using the command line which is faster. CodeSandbox is an online code editor and prototype tool that speeds up the creation and sharing of web apps where you can directly deploy your app without any hustle. - Source: dev.to / about 2 months ago

I am thankful for a platform like CodeSandbox because it allows me to offload majority of the processing power and memory resources to the cloud. With a local VS Code installed, I can tunnel in via a remote connection to work on my projects, tinker, or do a deep-dive on certain topics; all while ensuring that the RPi 4 still has sufficient resources left to run other things in the background. - Source: dev.to / over 1 year ago
