Thunderbit Alternative: Thunderbit Pricing and Alternatives for High-Volume Scraping

The right Thunderbit alternative is the one you move to when the credit meter becomes the job. Thunderbit Pro costs $38 a month for 3,000 rows, and a row with subpage details costs 2 credits, so a weekly refresh of 2,000 products with detail pages needs 16,000 credits and a custom quote. WebRobot starts at $79 a month for 10,000 records, with the REST API, scheduling and Slack delivery included. Below a few thousand rows, Thunderbit is cheaper, and this page says so.

Comparison

Thunderbit vs WebRobot: pricing and features

Thunderbit figures come from its public pricing page and FAQ. Plans change, and Thunderbit's yearly Pro price is marked as a limited-time discount, so confirm on thunderbit.com/pricing before you buy. Our side is on the WebRobot pricing page.

Free option	Free plan, 6 pages a month; 7-day trial of Pro features	No free tier; the interactive demo is the free taste
Entry paid plan	Starter $15/mo for 500 credits a month, or $9/mo yearly for 5,000 credits a year	Launch $79/mo or $63 billed yearly: 5 robots, 10,000 records/mo, daily scheduling, API

API	Web Scraper API sold as a separate product	REST API included on every plan
Logins, search forms, multi-step flows	Extension works on pages you already have open; AI Autofill fills forms in your browser	Agent actions on Scale and up: the robot signs in, searches and paginates on a schedule

Their pricing

Thunderbit pricing, plan by plan

Thunderbit's yearly plans hand you all credits upfront for the year, which is generous for bursty work and easy to burn through in one big job. Monthly plans reset every month.

Plan	Billed monthly	Billed yearly	Scheduled scrapers	Fastest monitor	Bulk URLs / paginated pages	Retention
Free	$0: 6 pages a month, max 30 credits per page		1	Daily	3 / 3	14 days
Starter	$15/mo, 500 credits a month	$9/mo, 5,000 credits a year	5	Hourly	2,000 / 200	60 days
Pro	$38/mo, 3,000 credits a month	$16.50/mo (list $24), 30,000 credits a year	25	5 minutes	2,000 / 200	60 days
Business	Custom credits, custom limits, priority support and account management

Worked bill 01

500 leads a month

A recruiter pulls 500 profiles from a directory list page. That is 500 credits: Thunderbit Starter at $15 a month, or $9 on the yearly plan. WebRobot Launch at $79 is the wrong purchase for this job.

Worked bill 02

2,000 products, weekly, with details

Each row pulls specs from the product page, so 2 credits a row. Four runs a month is 16,000 credits, more than five times Pro's 3,000. That is a Business quote. On WebRobot it is 8,000 records, inside Launch at $79.

Worked bill 03

2,000 products, every day

Daily competitor pricing with detail pages is about 60,000 rows and 120,000 Thunderbit credits a month. WebRobot Scale covers 100,000 records for $249, with hourly schedules and change alerts to Slack.

Fair play

Three reasons to stay on Thunderbit

Thunderbit is a good product for the job it was built for. If one of these describes you, an alternative costs more and gives you little back.

Advantage 01

Price at small volume

$9 to $38 a month is hard to beat when you need a few hundred or a few thousand rows. Our cheapest plan is $79. For a solo seller or recruiter scraping occasionally, Thunderbit is the better value.

Advantage 02

Two clicks on the page you are on

The extension reads whatever tab is open, which is ideal for ad hoc grabs while you browse. WebRobot is built around robots that run on a schedule, so a one-off copy of a single page is not where it shines.

Advantage 03

Browser helpers

AI Autofill, email, phone and image extractors and data enrichment sit in the same extension. If your workflow is filling forms by hand and grabbing contact details as you go, that bundle is convenient.

Switching triggers

Why teams search for a Thunderbit alternative

The trigger is almost always a recurring job that grew, not a one-off scrape.

Trigger 01

Out of credits halfway through the month

Thunderbit's own answer to running out is to upgrade or wait for the next cycle. When the job is a weekly price report, waiting is not an option, and above Pro the next step is a sales call. WebRobot plans publish the record allowance up to 1,000,000 a month.

Trigger 02

Detail pages cost double

The useful fields (specs, full descriptions, contact emails) usually live one click deep. Subpage rows cost 2 credits each on Thunderbit. WebRobot counts one record whether the robot read one page or two to fill it.

Trigger 03

The data has to reach a system, not a sheet

When rows feed a CRM, a pricing engine or your own app, you want an endpoint. Thunderbit sells its API separately; every WebRobot plan includes the web scraping API and webhooks.

Trigger 04

Portals behind a login, on a schedule

Supplier portals and member directories need a sign-in, a search and pagination every run. On Scale, agent actions do that unattended, and 5 seats let a pricing analyst and an engineer share the same robot.

Migration

How to move from Thunderbit to WebRobot in four steps

Export first. Thunderbit keeps paid-plan data for 60 days, and yearly credits do not come back as a refund.

Step 1

Export the last results

Download each scraper's latest table as CSV. The column headers become the field list for the robot, and you keep the history for comparison.

Step 2

Write one sentence per scraper

"From this search page, every listing with name, price, rating and the seller email from the detail page, all pages." Same start URL, same columns.

Step 3

Run both for a week

Keep the Thunderbit schedule on and compare row counts per run. Spot-check twenty rows field by field, especially the subpage fields.

Step 4

Repoint the destination

Move the Google Sheet, Slack channel or webhook to WebRobot, then downgrade Thunderbit at the end of the billing period, when downgrades take effect.

Most Thunderbit jobs that outgrow the extension are one of three. Sales teams building lists land on web scraping for lead generation, ecommerce teams on the price monitoring tool, and analysts who live in spreadsheets on scraping a website to Excel. For the wider market, the best web scraping tools roundup compares every major vendor.

FAQ

Thunderbit alternative questions buyers ask

Thunderbit Starter costs $15 per month billed monthly for 500 credits a month, or $9 per month billed yearly for 5,000 credits a year. Pro costs $38 per month for 3,000 credits a month, or $16.50 per month billed yearly for 30,000 credits a year during a limited-time discount from $24. Business pricing is custom. A free plan covers 6 pages a month.

One Thunderbit credit is one output row from the AI Web Scraper. With subpage scraping turned on, each row costs 2 credits. Advanced model messages cost 1 credit each and a data enrichment query costs 30 credits. Saving to Google Sheets, Airtable or Notion is free. When credits run out you upgrade or wait for the next billing cycle.

It depends on what you outgrew. For scheduled robots with more rows, logins, team seats and an API on every plan, WebRobot is the closest fit. For cheap monitoring of a few pages, Browse AI. For point-and-click desktop projects, Octoparse. For developers who host their own scrapers, Apify. If you scrape a few hundred rows a month, staying on Thunderbit is cheaper.

Thunderbit has a free plan limited to 6 pages a month with a maximum of 30 credits per page, plus a 7-day trial of Pro features. Subpage scraping, bulk scraping, pagination, pre-built scrapers and enrichment need a paid plan. Thunderbit does not refund unused time or credits after you cancel.

Yes, as a separate product. The Thunderbit Web Scraper API is listed next to the extension plans rather than inside them, with its own documentation and pricing. WebRobot includes its REST API and webhooks on every plan, starting with Launch at $79 per month.

Not for small jobs. Thunderbit Pro at $38 a month covers 3,000 rows, which is cheaper than WebRobot Launch at $79. The math flips past that point: Launch includes 10,000 records a month and Scale includes 100,000 for $249, while Thunderbit volumes above Pro move to custom Business pricing, and subpage rows cost double credits.

Yes, on Scale and Autopilot. Agent actions let the robot sign in with credentials you provide, run searches and follow pagination on a schedule, without a browser tab left open. Scrape only data you are entitled to access; the guide to scraping a website that requires login covers the rules to check first.
