Introducing Spidra tools: 8 free developer tools, no account needed

Today we are launching Spidra Tools, a collection of eight free utilities for developers working with web data.

You don't need to create an account, sign up, or connect a credit card to use them.

The Tools

These tools run on the same infrastructure as Spidra so you enjoy JavaScript-rendered pages, CAPTCHA solving to an extent and lots more.

Website to Markdown

Turn any URL into clean, LLM-ready Markdown in seconds.

Most Markdown converters make a plain HTTP request and convert whatever the server sends back. On modern React and Next.js sites, that is an empty shell. Our converter loads the page in a real browser so the JavaScript runs, the content populates, and then the conversion happens on the actual page.

You can strip navigation, footers, ads, and cookie banners before converting. What you get is the content. Perfect for feeding pages into LLMs, building RAG pipelines, or archiving articles.

Website to JSON

Describe what you want to extract from any webpage. Get back structured JSON.

Just tell it what you need in plain text: "Extract all product names and prices" or "Get the article title, author, and publish date." The same AI extraction engine that powers the Spidra API, available for free in your browser.

Website Screenshot

Capture a full-page or viewport screenshot of any website. Real browser rendering, downloads as PNG.

Try it →

AI Question Generator

Paste a URL and generate a set of questions from the page content. Great for building quiz material, study guides, research prep, or testing whether someone actually read the documentation. You control the number of questions and the format.

Try it →

Prettify JSON

Format, validate, and minify JSON instantly. Two spaces, four spaces, or tabs. Validates as you paste so you catch malformed JSON before it causes problems downstream.

Try it →

JSON to CSV

Convert any JSON array or object to a CSV file. Choose your delimiter, toggle headers, download instantly. Useful when you have API response data that needs to go into a spreadsheet or a tool that only accepts CSV.

Try it →

Markdown to HTML

Live Markdown to HTML conversion with a preview that updates as you type. Full GitHub Flavored Markdown support including tables, task lists, and fenced code blocks.

Try it →

Text Diff Checker

Compare two versions of any text side by side. Additions in green, deletions in red. Runs entirely in your browser so nothing gets sent to a server. That matters when you are comparing code, config files, or API responses.

What makes the scraping tools different

The Website to Markdown, Website to JSON, and Website Screenshot tools run on the same infrastructure as the Spidra API. Every request loads the page in a real headless browser. JavaScript executes fully. If there is a CAPTCHA, it gets handled. If the content is inside a framework, it renders before anything is extracted.

This is not a thin HTTP wrapper with a Markdown library on top. It is actual browser-based rendering available for free with no sign-up.

Get started

All eight tools are free and will stay free.

If you find yourself wanting to do any of this at scale, converting hundreds of pages, extracting structured data from a URL list, crawling an entire domain, the Spidra API handles all of that. Free tier with 300 credits, no card required.
