That’s [Next.js development](https://pentaclay.com/services/nextjs-development) . - You need updates and fixes every month. That’s [website maintenance](https://pentaclay.com/services/website-maintenance) . - You need a new site, written and designed. That’s [website design](https://pentaclay.com/services/b2b-website-design) . - Your site needs new copy and a new look.

[Book a call](https://cal.com/pentaclay/discovery-call) Or email us at [contact@pentaclay.com](mailto:contact@pentaclay.com) What’s the difference between custom web development and a Next.js site? Custom development adds code components or integrations to the site you have. A Next.js site is custom-coded from end to end: that’s our [Next.js development](https://pentaclay.com/services/nextjs-development) service. Can you connect our website to an outside API? Yes. On Comtel’s site, the coverage check in the first screen connects to an outside service that looks up the address. See the [Comtel case study](https://pentaclay.com/work/comtel) . Do you build custom Framer components? Yes. We build code components for Framer sites, and we publish Framer components of our own. Will custom code hide our content from AI search? Not if it’s built right. AI crawlers read the raw page and don’t run scripts, so we keep your text in the page. Can our team still edit the site after you add custom code? Yes. We add the part you’re missing and leave the rest of the site as it is, so your team keeps editing it without a developer. Who owns the custom code? You do, once the project is paid. The site, the code and every account are handed over to you. How much does custom web development cost? It depends on what we build and what it connects to: every integration has to be set up and tested. We quote it after a 30-minute call, with a fixed scope, price and date in writing within 3 business days. Starting prices are on our [pricing page](https://pentaclay.com/pricing) . Can you do one small tweak? Yes. [Book a call](https://cal.com/pentaclay/discovery-call) and tell us what you need; we quote it after the call. When the part has to fit your design, your platform and your launch date, the price goes in the contract. ## Need something else?
