Realm - Convex + TanStack SaaS Starter

A production-ready SaaS starter kit built on Convex, TanStack (Router, Query, Form, Start), Better-auth, and Cloudflare Workers. Schema-first with end-to-end types, so you define your data once and it flows through queries, mutations, routing, forms, and UI without codegen or hand-rolled API contracts.

Live Demo: https://realm.raymonda.xyz/

Auth: magic link, email OTP, and Google OAuth, with multi-tenant orgs, role-based access control, and invitation flows

Real-time reactive database with typed queries and mutations (Convex)

Billing: Stripe and Polar wired side-by-side. Checkout, webhooks, and subscription state persisted in your DB. Keep the one you prefer, delete the other.

File storage: presigned uploads to any S3-compatible bucket (Tigris, R2, Backblaze, AWS) via @mzedstudio/s3-seam. Avatar upload ships as the worked example.

Rate limiting: built-in token-bucket limiter guarding invites, billing actions, and any endpoint you want gated. No Redis to run.

Transactional email queue with cron-driven processing and branded templates (magic links, OTPs, invitations, billing receipts)

Dashboard shell: sidebar, top bar, drawer, toast, and skeleton primitives

Drop-in feature modules: backend and frontend mirror each other as self-contained slices, so removing a feature is one directory delete

SSR-by-default via TanStack Start, with streaming and route-level loaders

Edge deploys via Cloudflare Workers with staging and production preconfigured (GitHub Actions included)

Dinachi UI components on Base UI, vendored into your repo (no upstream lock-in)

TypeScript, Tailwind v4, Zod, Vitest, Turborepo, pnpm

One purchase, unlimited commercial projects. Free setup assistance included.
