In 2025, the author finds satisfaction in a fast, clean, and expressive developer stack that is enjoyable to work with.For frontend development, the author uses Next.js, Shadcn/ui, and TailwindCSS, creating a pleasant development environment.Next.js has improved with App Router, Server Actions, and caching strategies, enhancing the developer experience.Initially hesitant about TailwindCSS, the author now appreciates its speed, readability, and Just-in-Time mode.Shadcn/ui simplifies building accessible components with smarter defaults, offering more control to developers.Supabase is the author's favored backend choice in 2025, offering Postgres, realtime subscriptions, row-level security, and user uploads storage.Supabase Auth has made authentication flows easier with features like built-in email/password, OTPs, and reliable session persistence.Additional tools include Zod for schema validation, tRPC for typesafe APIs, Vercel for deployments, and GitHub Copilot for boilerplate assistance.Tools like Firebase, Redux, and custom UI kits have been dropped in favor of the more efficient components in the current stack.The author values a stack that is reliable, efficient, and allows for rapid development without compromising on functionality.Building a stack for 2025 should focus on tools that feel like natural extensions of one's workflow, rather than just following trends.
