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.\n\nOver 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.\n\nBut 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.\n\nSo 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.\n\nThen 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.\n\nI’m still shipping. I just want the next idea to start with the idea, directly.\n\n## Everything that comes with supastack.\n\n### Codebase\n\nNext.js and Expo share TypeScript modules so agents and humans extend one codebase instead of forking surfaces.\n\n### Auth\n\nEmail, OTP, and social providers land in Better Auth sessions scoped to the user’s personal workspace.\n\n### Payments\n\nCheckout, customer portal, and signed webhooks keep subscriptions and product access in sync. Swap Stripe for Paddle, Polar, or another adapter without rebuilding billing.\n\n### AI workflows\n\nRoute through OpenAI, Anthropic, or a compatible API with encrypted keys, usage tracking, and workspace budgets.\n\n### Wait, there's more!\n\n### Jobs + email\n\nTrigger.dev runs jobs through a narrow enqueue, status, and cancel contract. Transactional email stays separate from outreach.\n\n### Audit\n\nAudit records, analytics hooks, and sanitized error context keep operational history attached to the right workspace.\n\nAudit log\n\n| Event | Workspace | When | \n|---|---|---|\n|  | ws_8f2a | 2m | \n|  | ws_8f2a | 1h | \n|  | ws_8f2a | 1d | \n\n### Orgs\n\nInvitations, membership boundaries, and a consistent workspaceId scope connect identity, data, and product access — for a solo space or a full organization.\n\n### Email\n\nTransactional email belongs to product workflows, with provider adapters behind a shared interface—never mixed with outreach.\n\n### Key storage\n\nBring your own AI credentials without exposing provider secrets to the browser. Encryption stays server-side.\n\n### Usage budgets\n\nToken tracking, model-aware estimates, and workspace budgets put consumption in context before spend runs away.\n\n### Analytics\n\nAn analytics interface carries event properties and workspace context while redacting sensitive values.\n\n### Error monitoring\n\nCapture exceptions with workspace tags and sanitized context through the observability layer.\n\n## 21 themes, 4 layouts.\n\nNew workspace provisioned2 minutes ago\n\nInvoice paid18 minutes ago\n\nMember invited1 hour ago\n\nObsidian — Black field, warm amber actions.
