Thunderbit is an AI web scraper Chrome extension: you describe the data on any page and it builds a table, with templates for sites including Telegram. It is the right tool for someone who scrapes many different websites. It is the wrong tool for someone who only needs Telegram groups, WhatsApp contacts, LinkedIn searches or Instagram followers, because its plans meter credits per year and its templates are generic. The Mastros extensions do those five jobs with no credits and no prompt.
What is Thunderbit?
A Chrome extension that uses an AI model to read a web page, guess the columns you want and extract them, for any website, PDF or image. It sells to people who scrape often and everywhere: product lists, directories, listings. Its Telegram template is one of many.
How does Thunderbit's pricing work?
On the plans we checked in August 2026, credit allowances are counted per year, not per month, with a free tier of a few pages a month. A yearly credit pool reads like a monthly one until you divide by twelve, so compare the unit before comparing the price. Mastros prices by monthly export volume with a free tier, on each product page.

Is Thunderbit worth it?
Yes if the variety of sites is the point. No if the site is always the same one, because a purpose-built extension knows the page's structure, paginates it correctly, exports the fields that matter and costs less per month. That is the whole comparison.
