Show HN: Supastack – Cross-Platform Turborepo for Next.js, Expo, and Tauri

Developer Noah released Supastack, a full-stack TypeScript boilerplate that unifies Next.js for web, Expo for iOS and Android, and Tauri for desktop in one Turborepo monorepo, with one-time licenses starting at $249 as of October 2026. Supastack prewires authentication through Better Auth, team workspaces, Stripe billing with swappable adapters, AI provider routing across OpenAI, Anthropic, or compatible APIs with encrypted keys and workspace budgets, Trigger.dev background jobs, and transactional email. Noah said he built the boilerplate after repeatedly rebuilding login, payments, emails, a database, and deployment for each new project, and the product claims to save 90+ hours of setup work.

Watch on YouTube https://youtu.be/sAB3zR1uzW4 Hey, I’m Noah. In 2024, I thought I could build something big. I launched a teacher-rating platform—and ended up getting a call from my director. That project is now closed, but I haven’t stopped shipping. Over the past two years, I’ve tried dozens of projects: an AI image tool, an AI gateway, an AI learning app. Today, I’m still building LearnX https://learnx.pro , and I have plenty more ideas I want to try. But every new idea came with the same first week: wiring up login, payments, emails, a database, and deployment. Before I could build the part I was excited about, I was rebuilding the same foundation. So I built Supastack for myself: a boilerplate I could reuse whenever I wanted to start something new. Set up the foundation once, then spend my time on the idea. Then I realized I couldn’t be the only one stuck doing this. If it helped me spend more time building, maybe it could help you too. That’s why I’m sharing it. I’m still shipping. I just want the next idea to start with the idea, directly. Everything that comes with supastack. Codebase Next.js and Expo share TypeScript modules so agents and humans extend one codebase instead of forking surfaces. Auth Email, OTP, and social providers land in Better Auth sessions scoped to the user’s personal workspace. Payments Checkout, customer portal, and signed webhooks keep subscriptions and product access in sync. Swap Stripe for Paddle, Polar, or another adapter without rebuilding billing. AI workflows Route through OpenAI, Anthropic, or a compatible API with encrypted keys, usage tracking, and workspace budgets. Wait, there's more Jobs + email Trigger.dev runs jobs through a narrow enqueue, status, and cancel contract. Transactional email stays separate from outreach. Audit Audit records, analytics hooks, and sanitized error context keep operational history attached to the right workspace. Audit log | Event | Workspace | When | |---|---|---| | | ws 8f2a | 2m | | | ws 8f2a | 1h | | | ws 8f2a | 1d | Orgs Invitations, membership boundaries, and a consistent workspaceId scope connect identity, data, and product access — for a solo space or a full organization. Email Transactional email belongs to product workflows, with provider adapters behind a shared interface—never mixed with outreach. Key storage Bring your own AI credentials without exposing provider secrets to the browser. Encryption stays server-side. Usage budgets Token tracking, model-aware estimates, and workspace budgets put consumption in context before spend runs away. Analytics An analytics interface carries event properties and workspace context while redacting sensitive values. Error monitoring Capture exceptions with workspace tags and sanitized context through the observability layer. 21 themes, 4 layouts.
