500 directory leads a month
A recruiter pulls 500 profiles from a list page. That is 500 credits, so Starter at $15 a month fits exactly, or $9 a month on the yearly plan. WebRobot Launch at $79 is the wrong purchase for this job.
Thunderbit Pricing for Every Plan With Credit Costs per Row and Real Monthly Bills
8 min read
Thunderbit pricing starts at $15 a month for 500 credits on Starter and $38 for 3,000 on Pro, with larger Pro tiers up to $249 for 20,000 credits and a free plan of 6 pages. One credit is one output row, or 2 credits when the tool opens each row's detail page. That makes the real cost $12.45 to $30 per 1,000 rows on monthly billing and $6.60 to $21.60 on yearly.

| Plan | Monthly price | Credits a month | Yearly price and credits | Cost per 1,000 rows |
|---|---|---|---|---|
| Free | $0 | 6 pages a month | $0 | Max 30 credits per page, 1 scheduled scraper |
| Starter | $15 | 500 | $108 ($9 a month) for 5,000 credits | $30.00 monthly, $21.60 yearly |
| Pro Tier 1 | $38 | 3,000 | $288 list, shown at $198 ($16.50 a month) for 30,000 | $12.67 monthly, $6.60 to $9.60 yearly |
| Pro Tier 2 | $75 | 6,000 | $576 for 60,000 | $12.50 monthly, $9.60 yearly |
| Pro Tier 3 | $125 | 10,000 | $1,152 for 120,000 | $12.50 monthly, $9.60 yearly |
| Pro Tier 4 | $249 | 20,000 | $2,304 for 240,000 | $12.45 monthly, $9.60 yearly |
| Business | Custom | Custom | Custom | Quoted by sales |
The yearly Pro Tier 1 price deserves a caution. The $16.50 a month figure is marked as a limited-time discount from $24, so budget $288 a year if it reverts. Tiers 2 to 4 sit at $9.60 per 1,000 credits on yearly billing, which is the same rate as Pro Tier 1 at list, so the discount is the only reason Tier 1 looks cheaper. Higher Pro tiers also keep the same features, so the extra money buys credits and nothing else.
The meter
How Thunderbit credits are counted
The unit is a row, not a page, which makes the bill easy to predict until subpages or enrichment come in.
| Action | Credits | What it means in practice |
|---|---|---|
| One output row | 1 credit | A list page with 50 products is 50 credits |
| A row with subpage scraping | 2 credits | The tool opens each row's detail page to add fields |
| Advanced model message | 1 credit | Used when the extraction needs the stronger model |
| Data enrichment query | 30 credits | Adds researched fields to a row |
| Save to Sheets, Airtable or Notion | 0 credits | Exports are free |
Subpage scraping is the switch that changes the plan you need. A product list with name and price is cheap. A list that also needs stock, specs or seller from each product page costs twice as much, and enrichment costs thirty times a row. Check which of your fields sit on the list page and which need the detail page before you pick a tier. The Thunderbit alternative page compares the product feature by feature.

Monthly billing, list rates, before tax.
Worked bill 02
2,000 products, weekly, with detail pages
Each row needs the detail page, so 2 credits a row. Four runs a month is 16,000 credits, which is more than Pro Tier 3's 10,000 and puts you on Tier 4 at $249 a month. On WebRobot it is 8,000 records, inside Launch at $79.
Worked bill 03
2,000 products, every day, with detail pages
About 60,000 rows and 120,000 credits a month, six times the largest listed Pro tier. That is a Business quote. WebRobot Scale covers 100,000 records for $249, with hourly schedules and change alerts to Slack.
Worked bill 04
One 30,000-row list build for an outreach campaign
An agency scraping prospect sites for building outreach lists for link placements uses 30,000 credits once. Yearly Pro Tier 1 at $198 is the cheapest way to get them, and for a one-off job Thunderbit wins.
Compared
Thunderbit vs WebRobot on cost per 1,000 rows
Same output unit, one row or record, at full use of each plan. Rows with detail pages count double on Thunderbit.
| Plan | Volume a month | Price a month | Per 1,000 rows |
|---|---|---|---|
| Starter, monthly | 500 rows | $15 | $30.00 |
| Pro Tier 1, monthly | 3,000 rows | $38 | $12.67 |
| Pro Tier 4, monthly | 20,000 rows | $249 | $12.45 |
| Pro Tier 1, yearly (promo) | 2,500 rows a month | $16.50 | $6.60 |
| WebRobot Launch | 10,000 records | $79 | $7.90 |
| WebRobot Scale | 100,000 records | $249 | $2.49 |
The pattern is simple. Thunderbit wins below about 3,000 rows a month and on one-off yearly jobs. Past roughly 6,000 rows a month, or whenever detail pages double the credit count, a flat plan is cheaper, and a WebRobot record stays one unit whether the robot read one page or three. The WebRobot pricing page lists every plan and billing period.
Which plan
Which Thunderbit plan to buy, and when to skip it
Buy Starter or Pro Tier 1
Occasional lists
You scrape a few hundred to a few thousand rows a month, mostly by hand, and want them in a sheet today. Take yearly if the work is bursty.
Buy Pro Tier 3 or 4
Recurring weekly jobs
Steady volume under 20,000 rows a month with list-page fields only. Remember that detail pages halve the volume.
Skip it
Daily jobs and detail pages
Daily runs across thousands of products, logins, or a team that needs an endpoint. That is what competitor price monitoring on WebRobot is for, from the $79 Launch plan.
Before you pay
Billing rules to know before you buy Thunderbit
Refunds
No refund on unused time
Thunderbit does not refund unused time or credits after you cancel, so a yearly plan is a commitment, not a trial.
Retention
14 to 60 days
Free keeps data 14 days, paid plans 60 days. Export before the window closes if you need history.
Running out
Upgrade or wait
There is no per-row overage. Out of credits means a plan change or waiting for the next cycle.

FAQ
Thunderbit pricing questions, answered
Thunderbit costs $15 a month for 500 credits on Starter and $38 for 3,000 credits on Pro. Larger Pro tiers cost $75 for 6,000, $125 for 10,000 and $249 for 20,000 credits a month. Yearly billing is $108 for Starter and $288 for Pro Tier 1, shown at $198 during a limited discount, and Business is custom.
Only to test. The free plan covers 6 pages a month with a maximum of 30 credits per page. Subpage scraping, bulk scraping, pagination, pre-built scrapers and enrichment need a paid plan, and the paid plans have no refund for unused time or credits after you cancel.
One credit is one output row from the AI Web Scraper. With subpage scraping on, each row costs 2 credits because the tool opens a second page for it. Advanced model messages cost 1 credit each, a data enrichment query costs 30, and saving to Google Sheets, Airtable or Notion is free.
You upgrade your plan or wait for the next billing cycle. Thunderbit does not bill overage per row. On monthly plans credits reset each month. On yearly plans all credits are granted upfront for the year, so one large job can use up the allowance months early.
For occasional or bursty work, yes. Yearly Pro Tier 1 gives 30,000 credits for $198 during the current discount, $6.60 per 1,000 rows against $12.67 on the monthly plan. If your work is steady and recurring, the credits come out of one pool, so heavy months drain it.
Not for small jobs. Thunderbit Pro at $38 covers 3,000 rows, which is cheaper than WebRobot Launch at $79. The math flips on recurring volume: Launch includes 10,000 records a month, Scale includes 100,000 for $249, and a record costs one unit whether the robot read one page or two.
