StackScan — Technographic lead generation database
Tool Overview
Finding qualified prospects still takes hours of manual research, guesswork about what tools a company uses, and endless tab-switching. StackScan cuts through that by indexing 360 million websites across 55,000+ detected technologies, so you can pull a list of every site running Shopify, HubSpot, or any other platform in seconds.
The platform gives you two distinct search modes: Tech Lookup finds websites by the specific tools they use, while Keyword Scan surfaces sites by topic, niche, or buyer intent. Results can be filtered by country, TLD, and stack combinations, then exported as a CSV ready to drop into your CRM.

Our Take on StackScan
StackScan fills a real gap in the market: technographic prospecting at a price point that smaller teams can actually afford. BuiltWith starts at $295 per month and Wappalyzer’s paid tier runs $250 per month. A one-time $129 for the same category of data is a genuinely different proposition.
The dual-tool setup is the most practical thing about it. Tech Lookup answers ‘who is using X tool right now’ and Keyword Scan answers ‘who is writing about or focused on Y topic.’ Together they cover both technology-based and intent-based prospecting from a single platform.
The credit system takes a moment to understand. Each credit unlocks one technology report permanently for that month, and you can rebuild it as many times as needed without burning another credit. Keyword downloads work differently though: each download costs a credit and cannot be rebuilt free. New users should read that distinction before diving into bulk keyword scans.
Best fit for solo SDRs, agency researchers, and lean marketing teams who do regular prospecting but cannot justify a $300 per month SaaS bill for data they only need a few times a week.
At a Glance
What stands out
The index covers 360 million websites and 55,000+ tracked technologies, which puts it in the same data tier as tools costing six to eight times more per month.
Rebuilt tech reports within the same month don't consume additional credits, so you can refresh a Shopify list or re-run a HubSpot search without worrying about burning through your allocation.
Keyword Scan goes beyond tool detection by surfacing websites based on topic or buyer intent, which lets you build niche prospect lists that a pure technographic tool would miss entirely.
Stack Explorer lets you browse technology categories and review global adoption stats before committing a credit, which helps you sanity-check market size before building a list.
Things to note
The credit pool resets monthly, but unused credits do not roll over, so lighter users on the Pro tier (5 credits per month) may leave capacity on the table in slow months.
Keyword report downloads cannot be rebuilt free the way tech reports can, meaning each fresh keyword CSV costs a credit regardless of how recently you ran a similar query.
All three lifetime plans are single-user accounts, so teams needing shared access will need to coordinate or wait for potential future multi-seat options.
The platform is still building out its roadmap and was in early-traction mode as of its lifetime deal launch, so feature depth in areas like company enrichment and contact data is thinner than established enterprise tools.

Founder and Company Information
StackScan was founded by Manish Patel, who built the platform to address the cost gap between enterprise technographic tools and what smaller teams can realistically afford. Patel has been deliberate about brand clarity, choosing the stackscan.com domain specifically because it communicates the product’s core function in two words.
The company is bootstrapped and self-funded, running a lifetime deal to gather early user feedback and traction before moving to a standard subscription model.

StackScan's Key Features
Tech Lookup Tool — Search the 360M+ site index by any of 55,000+ detected technologies, including CMS platforms, ecommerce tools, analytics scripts, payment processors, and JavaScript frameworks, then export the matching domain list.
Keyword Scan Tool — Find websites based on page content, topic, or niche intent rather than installed technology, letting you build prospect lists around what a site talks about rather than just what it runs.
Advanced Filtering — Narrow any result set by country, TLD, domain type, and technology stack combinations to remove noise and concentrate the export on the segment you actually want to reach.
Stack Explorer — Browse technologies by category, review global adoption numbers and country-level usage breakdowns, and jump directly into a Tech Lookup from the explorer without starting from scratch.
CSV and XLS Export — Download filtered website lists in CSV or XLS format, with up to 100,000 rows per list on the Pro tier and up to 150,000 rows on Business, ready to import into any CRM or outreach tool.
Credit Reinstatement Policy — If StackScan incorrectly detects a technology on a lookup, the team reviews the case and returns the spent credit, which provides a practical safety net against data errors eating into your monthly allocation.
StackScan's Use Cases
SDRs and outbound sales reps who build targeted call and email lists by the tools their prospects use, such as finding all Salesforce shops with 50 or more employees in a given country.
Agency and freelance marketers who need to show clients a qualified prospect pool segmented by platform, vertical, or geography without paying enterprise data prices every month.
SaaS founders doing pre-launch market sizing research who want to see exactly how many sites run a competing or complementary tool before deciding where to focus.
SEO and link-building specialists who use keyword and technology filters to find topically relevant domains for outreach rather than manually scraping site lists from search results.

Similar Alternatives to StackScan
BuiltWith
The longest-running technographic database, with historical adoption data and deep filtering, but entry pricing starts at $295 per month, making it hard to justify for solo users or small teams.
Wappalyzer
Good for per-site technology detection via browser extension, with a paid tier at $250 per month for bulk lookups, though credits expire after 60 days and there is no keyword-intent discovery mode.
SimilarTech
Positioned more as a market-share analytics tool than a lead list generator, useful for studying technology adoption trends across industries but less practical for building outbound prospect lists quickly.
TheirStack
A newer technographic tool that focuses on backend and job-signal-based detection rather than website crawling, with a free tier and paid plans from $59 per month for teams wanting intent signals beyond visible tech stacks.
User Reviews for StackScan
Marcus T.
★★★★★
I've been using StackScan for about two months to build Shopify prospect lists for a Klaviyo integration pitch. The Tech Lookup filters by country and TLD work exactly as advertised. The credit rebuild feature is genuinely useful since I refreshed the same Shopify list three times in one month without spending extra credits.
Priya S.
★★★★☆
The keyword scan tool surprised me. I wasn't expecting it to be as targeted as it is for finding niche blogs and content sites. The one thing I wish was clearer upfront is that keyword downloads cost a credit each time, unlike tech reports which you can rebuild free. Once I understood that, I stopped burning credits unnecessarily.
(Based on product analysis)
★★★★☆
For the price, the data coverage is hard to argue with. Running 360 million indexed websites against 55,000 tracked technologies gives you enough breadth to work with in almost any B2B vertical. The five-credit monthly limit on the Pro tier is tight if you're doing frequent outbound cycles, but the Business tier at $259 lifetime solves that.
(Based on product analysis)
★★★★☆
The Stack Explorer feature doesn't get mentioned enough. Being able to browse technology categories and see adoption numbers before you commit a credit to a full lookup helps you validate whether a market is large enough to bother targeting. It's a small thing that saves real time during planning.
Here's what our community thinks about StackScan
Here's what people are asking about StackScan (FAQs)
How does the credit system work?▼
Each monthly credit unlocks one technology lookup. Once you run a Tech Lookup, you can rebuild that same report as many times as you want within the month without spending another credit. Keyword Scan works differently: a credit is consumed each time you download a keyword report, and those downloads cannot be rebuilt free.
Do unused credits carry over to the next month?▼
No, credits reset each month and unused ones do not roll over. If you're on the Pro tier with 5 credits per month and only use 3 in a given month, the remaining 2 are lost. Plan your lookups accordingly or consider the Business tier if you anticipate heavier use.
What happens if StackScan detects a technology incorrectly?▼
StackScan has a credit reinstatement policy for bad detections. If a technology is flagged incorrectly on your lookup, you can report it and the team will review it and return the credit after confirmation. You can also request detection support for technologies that are not yet in the database.
Is the lifetime deal available indefinitely?▼
No. StackScan has stated that the lifetime deal is available for a limited period only and will close once a target number of sales is reached. The deal is positioned as an early-traction offer while the team gathers user feedback, so availability is not guaranteed long-term.
Can I share one account across multiple team members?▼
All three lifetime plans are single-user accounts. There is no built-in multi-seat option in the current lifetime deal tiers. Teams that need shared access would need separate accounts or should watch for future enterprise plan announcements from the StackScan team.
