Tech Bro's Build An App in 1 Week
This is the tech stack I rely on to build and launch fully functional apps within a week. After years of experimenting with different combinations and shipping six failed products, I’ve refined a setup that balances speed, flexibility, and ease of use—especially for solo developers. It lets me move fast, iterate quickly, and get real feedback without getting bogged down in infrastructure or boilerplate. Below is a breakdown of the tools I use across frontend, backend, mobile, deployment, auth, and analytics.
8 tools

Vercel

"Hosting and deployment platform designed for frontend frameworks like Next.js. Great for solo developers who want zero-config deployments, automatic previews, and fast global CDN. Handles all CI/CD and infrastructure setup out of the box, making it easy to push changes and go live instantly without thinking about DevOps." - Dohyun Kim
Deploy, preview, and ship websites effortlessly.

Flutter

"Mobile UI toolkit by Google for building native apps from a single codebase. Chosen over React Native for its fast rendering engine and consistent cross-platform performance. Great developer experience with hot reload, custom UI flexibility, and support for Android and iOS in one go. Compiles to native code for better performance." - Dohyun Kim
Cross-platform mobile, web, and desktop apps from one codebase.

Codemagic

"CI/CD tool made for mobile apps, especially Flutter. Automates the process of building, testing, and publishing apps to the App Store and Play Store. Saves time by handling certificates, signing, and build configs. Great for solo devs looking to avoid the pain of mobile deployment setup and just ship." - Dohyun Kim
Builds, tests, and releases mobile apps with automated ease.

Supabase

"All-in-one backend platform built on Postgres, used for authentication, database, storage, and edge functions. Chosen for its Firebase-like experience with SQL under the hood. Great for fast prototyping with a single tool. Especially useful when you want everything in one place without stitching together services manually." - Dohyun Kim
Open-source Firebase alternative with AI-powered database.

PlanetScale Vitess Operator

"Serverless MySQL-compatible database platform built on Vitess. Chosen for its scalability, zero-downtime schema changes, and Git-style branch workflows. Great for production apps that need to scale reliably. Used with Prisma to provide type-safe access and better dev experience than traditional DBs." - Dohyun Kim
Scales MySQL databases effortlessly, simplifying complex deployments.

Prisma

"ORM for TypeScript that simplifies database access and schema management. Used alongside PlanetScale to write safe, typed queries and manage migrations. Offers introspection and auto-generated client APIs for productivity. Helps maintain clean code and reduces chances of DB-related bugs in production." - Dohyun Kim
Easy database access for developers, simplifying queries and scaling.

Clerk.dev

"Authentication service. Chosen over Supabase Auth for its specialized and robust auth features like user management, sessions, and UI components. Provides drop-in React/Next.js components, supports passwordless login, SSO, and handles edge cases like multi-session management. Ideal for devs who want solid auth without complexity." - Dohyun Kim
Drop-in user accounts: auth, profiles, and security made easy.

PostHog

"Open-source product analytics suite with built-in support for feature flags, A/B testing, and funnels. Chosen for its ability to self-host and track detailed user behavior without relying on third parties. Enables you to analyze retention, user flows, and safely release features with gradual rollouts. Central to understanding product usage." - Dohyun Kim
Open-source product analytics, feature flags, and session recordings.
An AI tool that observes your work, finds inefficiencies, and suggests smarter ways to do things. Maybe you can use your tools better, automate tasks, or switch software.
