Our team makes the decisions and stands behind the work. - hyperAI Choosing the right stack ## When Next.js is the right choice. Not every website needs a custom application framework. We recommend Next.js when your product requires deeper functionality, integrations, and engineering control. - ### Your product has real application workflows. Users need accounts, permissions, dashboards, transactions, and connected data. - ### Your systems need to work together. You need to connect APIs, external services, a database, or internal business tools. - ### Your product will keep evolving. New workflows, integrations, and features need an architecture your team can maintain. - ### You need control over the implementation. Your engineering team needs access to the code, deployment configuration, and technical decisions. ### When another platform makes more sense If your main goal is a marketing website with frequent visual updates and limited custom application logic, Framer, Webflow, or Astro may be a better fit. We'll recommend the approach that matches your team and requirements. - [Astro](https://gr8rstudio.com/services/astro) - [Framer](https://gr8rstudio.com/services/framer) - [Webflow](https://gr8rstudio.com/services/webflow) What we engineer ## Software built around how your business works. From the interfaces customers use to the systems behind them, we connect design and engineering into one product experience. - 01 ### SaaS platforms & dashboards Customer portals, multi-user workspaces, account management, and data-rich dashboards. - 02 ### AI-powered applications AI assistants, intelligent search, and AI features connected to real product workflows. - 03 ### Custom business software Internal tools and operational platforms that replace fragmented manual processes. - 04 ### APIs, authentication & integrations Secure sign-in, user permissions, payments, databases, and third-party connections. - 05 ### Performance & production readiness Rendering, caching, accessibility, security reviews, and performance checks appropriate to your product. - 06 ### Documentation & handover An organized codebase, agreed documentation, and a walkthrough for your team.

Miguel Queirós Collaborator FAQ ## Questions about Next.js Development Ask anything else Reading our answers… - How much does a Next.js project cost? Projects start at $8,000\. Final pricing depends on the scope, integrations, design requirements, and complexity of the software. We agree on deliverables, timeline, and cost in writing before work begins. - Can you rebuild or migrate our existing website or app? Yes. We first review your current platform, content, application logic, integrations, and SEO requirements. Then we recommend what can be migrated, what needs rebuilding, and how to reduce disruption during the transition. - Do you handle design and development together? Yes. We can work from your existing designs or handle product UX, interface design, and Next.js engineering as one engagement. This helps align the user experience with technical requirements before development begins. - Can you connect our existing tools, database, and APIs? Yes, depending on the systems involved and their available integrations. We assess authentication, data flow, permissions, and API limitations before defining the technical scope. - How do you approach performance, security, and SEO? We plan performance, security, and search requirements around the product. That can include rendering and caching strategy, access controls, image optimization, metadata, and testing. Exact checks and targets are agreed as part of the scope. - Can our team maintain the product after launch? We aim to deliver readable, organized code and agreed documentation so your developers can continue the work. If your team needs onboarding, a walkthrough, or ongoing support, we can scope that separately. - Who owns the code and repository? Your agreement defines ownership and handover. For custom development, we aim to keep the repository, deployment access, and agreed project files under your control, subject to third-party tools and licenses. ## Need more than a build?
