Questions and Answers

As answered by people managing JSONLint and PulpMiner.

What makes your product unique?

PulpMiner's answer:

PulpMiner is the easiest way to turn any webpage into a clean, structured API. What makes it unique is its ability to automatically generate smart JSON templates using AI, eliminating the need for manual schema design. With just a URL, users can create fast, real-time, cacheable API endpoints — all without writing a single line of code.

Why should a person choose your product over its competitors?

PulpMiner's answer:

Unlike most web scraping tools that require complex setup or coding knowledge, PulpMiner offers a plug-and-play experience powered by AI. It’s affordable, credit-based (no monthly lock-ins), and uses top-tier infrastructure like Cloudflare Workers and powerful non-blocking scrapers for reliability and access. You get real-time data, fast responses, and the ability to customize your outputs with minimal effort.

How would you describe your primary audience?

PulpMiner's answer:

Our primary audience includes indie developers, no-code/low-code builders, SaaS founders, data analysts, and marketers who need structured web data for automation, reporting, or integrating with other tools — without the usual headaches of scraping.

What's the story behind your product?

PulpMiner's answer:

PulpMiner was born from the frustration of building scrapers for every new project. While exploring ways to automate this repetitive work, we realized there was no simple, AI-powered solution to convert webpages into structured APIs — especially one that didn’t require subscriptions or complex configurations. That gap led to the creation of PulpMiner, a lightweight but powerful tool built for speed, scale, and simplicity.

Which are the primary technologies used for building your product?

PulpMiner's answer:

Cloudflare Workers (for backend)

Vercel (for frontend hosting)

Cloudflare KV (for data caching)

Clerk (for authentication)

Paddle (for credit-based payments and licensing)

Who are some of the biggest customers of your product?

PulpMiner's answer:

Indie SaaS founders scraping pricing data for competitors

E-commerce consultants extracting product data from supplier sites

No-code builders integrating data into Airtable/Notion

Marketing agencies automating web data collection

Startup growth teams building real-time dashboards
