Beyond Web3, XDefiDev is a full-stack software engineering partner. We design, build, and ship custom web and mobile applications, internal tools, SaaS products, and integrations that solve real business problems.
Using modern stacks like Next.js, React, Node.js, and React Native, we cover the full product lifecycle: architecture, UI/UX, backend APIs, databases, testing, and cloud deployment.

Fixed price for products, starting prices for services. Pay with crypto or request a quote.
Timelines depend on scope: an MVP web app typically takes 2-4 weeks, a full SaaS product 6-12 weeks, and a complex platform with multiple integrations 3-6 months. We deliver in phases with demos at each milestone.
Simple web applications start at $1,000, full SaaS products range from $5,000-$25,000, and large platforms with mobile apps and cloud infrastructure can exceed $50,000. We provide fixed-price quotes based on a detailed scope.
We build with modern, well-supported stacks: Next.js, React, Node.js, TypeScript, PostgreSQL, MongoDB, AWS/GCP/Azure, Docker, and Kubernetes, and ship cross-platform mobile apps with React Native and Flutter.
Yes, we offer ongoing maintenance plans covering bug fixes, security patches, feature development, performance monitoring, and cloud cost optimization.
