Book a call Developers come for the code. The company pays for the cloud or enterprise plan. We build a site that makes the line between free and paid easy to see.
Companies that trusted us with their website
An open-source or API-first website serves the developer who adopts it for free and the company that pays for more. It needs a clear line between what is free and what is paid, docs and an API reference one click away, self-host and cloud options side by side, and the security answers a company asks before it pays. In our study of YC homepages (10 Oct 2026), 41 of 107 open-source companies run their site on Next.js. Pentaclay is a B2B website design agency for AI companies. We write, design and build these sites in Framer, Webflow or Next.js.
Can I see work like ours?
Yes. See our recent B2B work.
How long does a full website take?
6 weeks, from the first call to launch.
When do I see the price?
Scope, price and launch date in writing within 3 business days.
Which platforms do you build in?
Framer, Webflow, Next.js or another platform.
And how we’d fix each one on your website.
Developers love the repo, but nobody can find what the paid plan adds.
We put free and paid side by side: what the open-source version does, what the cloud or enterprise plan adds, and what drives the price.
Self-host or cloud? Our site makes people dig to compare them.
We compare both on one page, with who each one suits and what each one includes.
Our API reference is great, but the homepage doesn’t link to it.
We put docs, the quickstart and the API reference one click from every page, plus a repo link so developers can check activity.
Our site only gets updated between releases, when the team has a spare hour.
We write all the copy, and you approve it before we design. Then we build a site your engineers can own, or one marketing can run.
Free for the developer. Clear for the company that pays.
What the open-source or free tier does, and what the cloud or enterprise plan adds.
One click from every page.
Compared plainly.
A link, so developers can check activity themselves.
Status page and uptime target.
Certifications, SSO and data handling for the paid plan.
Companies a customer can check.
Releases and what changed in each, so teams see the project ships.
Our most recent work for B2B teams.
Clubs see the scale of the model before they read a word
An AI model of football is hard to picture. So the first screen leads with one number: 1.1 billion on-pitch events. The team publishes blog posts, media and glossary terms without a developer.
Families and schools each find their own way in
Families and schools wanted different things from one site. Families download a free app. Schools book a demo. A “Choose your path” choice on the first screen sends each one the right way.
Universities, brands and athletes each get a page made for them
One platform, three audiences: universities, brands and athletes. We built their design: a first screen that cycles through all three, a page for each, and a news room the team runs.
“Working with Kazi was great, and we’re very pleased with the outcome.”
Nima NejadChief Creative Officer, NOCAP SportsInvestors and borrowers each get their own first step
One lender, two audiences with opposite goals. Investors put money in. Borrowers take it out. So the first screen gives each one a button of their own, and every deal gets a page the team edits itself.

Put free and paid side by side: what the open-source version does, and what the cloud or enterprise plan adds. Then say what drives the price.
Yes. Show both, with who each one suits and what each one includes.
Yes, if your engineers will own it. Next.js is the most common platform among YC open-source companies (41 of 107). Our client work so far is in Framer and Webflow. Our Next.js work is our own website templates.
A full website usually takes 6 weeks, and we can work faster if your date needs it. A landing page takes 2 to 3 weeks. The date goes into the contract.
What teams in this industry book us for.
If customers need a demo just to understand what you sell, your website isn’t doing its job.
