In four steps
From idea to embedded in minutes
Building an interactive tool used to mean hiring a developer. With CalcStack it is a visual configuration and a single line of embed code. Here is the whole path. For the deeper version, see how it works.
Step 1
Pick a tool
Calculator, quiz, scorecard, benchmark, and more.
Step 2
Configure it
Set inputs and a formula or questions in the visual builder.
Step 3
Embed it
Copy one line of code onto any website.
Step 4
Capture leads
Visitors who complete it arrive in your CRM, scored.
Why build a tool instead of a form
It out-converts a form
People give their details in exchange for a personalized result, not in exchange for nothing.
It captures context, not just an email
Every input the visitor enters travels with the lead, so follow-up is informed.
It works everywhere
One embed line drops into any CMS or site builder, no developer required.

Questions
Frequently Asked Questions
I just clicked a 'Powered by CalcStack' badge. What is CalcStack?
CalcStack is the platform that built the interactive tool you just used. It lets any business add embeddable calculators, scorecards, quizzes, graders, decision tools, and benchmarks to their website, then captures and qualifies the people who use them as leads. You can build your own free, no code required.
How long does it take to build my first tool?
Minutes. You pick a tool type, configure inputs and a formula or questions in the builder, and copy a single line of embed code onto your site. Most first tools are live the same day with no developer involved.
Is it really free to start?
Yes. The free plan includes interactive tools with lead capture and basic analytics, with no credit card required. You upgrade only when you need to capture more leads per month, remove CalcStack branding, or route leads to your CRM.
What happens to the leads my tool captures?
Every person who completes your tool can be captured with the inputs they entered, scored by quality, and routed to your CRM or inbox. Unlike a static form that collects only an email, an interactive tool captures the context your sales team needs to prioritize follow-up.
Do I need to know how to code?
No. Tools are configured visually and embedded with one line of code you paste like a YouTube video. CalcStack works on WordPress, Webflow, Wix, Shopify, Squarespace, Framer, and plain HTML.
