A batteries-included starting point for a multi-tenant, role-aware SSR app: Nuxt 4, Supabase (Postgres + Auth), Nuxt UI v4, i18n (English + Serbian), plus observability, notifications, seeding, and release tooling wired up. One example CRUD (notes) shows the pattern to copy for your own domain.

Using this as a template? Click "Use this template" on GitHub, then follow SETUP.md — one rename command and env setup and it's yours.

• Auth — email/password + social login (GitHub, Google via Supabase OAuth), registration, password reset, email confirmation. Global role-aware middleware (app/middleware/auth.global.ts), not the module redirect.
• Multi-tenancy — every table is tenant-scoped by RLS via a current_tenant_id() helper. Self-service registration creates a tenant with the registrant as admin.
• Roles — member / admin, enforced by RLS (the real gate) + page meta (UX).
• Example CRUD — notes, RLS-scoped. layers/notes/app/composables/useNotes.ts + layers/notes/app/pages/notes/*.
• Notifications — in-app feed + bell + transactional email (Resend). A DB trigger fans a new note out to tenant admins; a DB webhook mirrors it to email. Off by default — flip NUXT_PUBLIC_NOTIFICATIONS_ENABLED=true.
• Billing — Polar checkout + customer portal + webhook, plan gating via useSubscription() (layers/billing). Off until keys are set.
• Account & admin — self-serve account deletion; admin user list with invite / set-role / ban / delete / impersonate (layers/{account,admin}); two-factor login with recovery codes (enforced by RLS), signed-in sessions, idle sign-out, synced preferences (language, theme, accent, typeface, text size, contrast, motion), API keys for a read-only /api/v1.
• Transactional email — Resend + a typed template layer with a dev preview route at /dev/emails (layers/email).
• Feedback — self-hosted in-app widget, RLS-scoped, no third-party script (layers/feedback). Off by default.
• Onboarding tour — driver.js first-run product tour targeting nav by href (layers/tour). Off by default.
• Analytics & flags — PostHog pageviews + useFeatureFlag() that degrades to a fallback when PostHog is off (layers/analytics). Off by default.
• Observability — Sentry (client + server + 5xx forwarding + tunnel), BetterStack log forwarding, Vercel Analytics + Speed Insights. All no-op until configured.
• Seeding — pnpm seed builds a demo tenant (admin + members + notes) with @faker-js/faker. Idempotent; wipes the @example.com demo domain first.
• i18n — en (default) + sr, parity-checked in CI.
• Testing — vitest (pure logic, 100% coverage gate on the logic layer) + Playwright (e2e + a11y via axe, both themes). Includes a tenant-isolation e2e that proves one tenant can never read another's rows through RLS.
• DX — pnpm setup (pick your integrations, it writes .env), pnpm doctor (verifies them — both driven by one manifest), pnpm gen:layer <name> to scaffold a feature, and Claude Code skills checked into .claude/skills/.
• CI/release — GitHub Actions (lint/test/typecheck, scheduled a11y, PR visual regression) + release-please + a user-facing /changelog.

📖 Documentation → gstack.goranninkovic.com — getting started, architecture, and the reasoning. Source in site/.

This is the GStack. What it is and why: docs/gstack.md. What's built and what's next: docs/roadmap.md. Key decisions (payments, data layer, Redis, distribution): docs/adr/.

Get the code — it's a GitHub template repository, so make your own repo from it rather than forking:

# GitHub CLI: creates your repo from the template and clones it
gh repo create my-app --template TerrorSquad/gstack --private --clone && cd my-app

# or, no GitHub account needed (downloads the files, no git history)
pnpm dlx degit TerrorSquad/gstack my-app && cd my-app && git init

Then:

pnpm install
cp .env.example .env          # fill in after `pnpm supabase start`
pnpm setup                    # pick which integrations to enable + stub their env vars
pnpm supabase start           # local Postgres + Auth (needs Docker)
pnpm db:reset                 # apply the migration + seed
pnpm db:types                 # regenerate the typed client from the live schema
pnpm dev                      # http://localhost:3000

Demo logins after pnpm db:reset: [email protected] / [email protected], password Demo123!Demo123.

The typed client (shared/types/database.types.ts) ships hand-written so pnpm dev and typecheck work before Supabase is up. Run pnpm db:types to regenerate it.

pnpm dev / build / preview
pnpm test              # vitest unit tests
pnpm test:e2e          # Playwright e2e + a11y (needs seeded local Supabase)
pnpm lint / fmt
pnpm lint:i18n / lint:i18n-keys
pnpm db:reset          # reset local DB + migrate + seed
pnpm db:types          # regenerate shared/types/database.types.ts
pnpm seed              # reseed (SEED_FAST=1 for the minimal set)

Registration makes you your tenant's admin automatically. To promote a member:

update public.profiles set role = 'admin' where email = '[email protected]';

• Notifications email: set NUXT_PUBLIC_NOTIFICATIONS_ENABLED=true, NUXT_RESEND_KEY, and NUXT_NOTIFICATION_WEBHOOK_SECRET, then add a Supabase DB webhook on notifications INSERT → POST /api/hooks/notification-email with the secret header.
• Social login: enable [auth.external.github] / [auth.external.google] in supabase/config.toml, set the client id/secret env vars (see .env.example), and restart local Supabase. The login-page buttons are already wired.
• Sentry: set NUXT_PUBLIC_SENTRY_DSN (+ org/project in nuxt.config.ts).

• Branding is generic ("GStack", indigo theme). node scripts/rename.mjs "My App" swaps the display name everywhere; brand palette (layers/ui/app/assets/css/main.css), favicon and LICENSE are by hand — see SETUP.md.
• Auth email templates (supabase/templates/*.html) are generated from the same shell as the app's own mail — edit scripts/gen-auth-templates.ts, not the HTML, then pnpm gen:auth-templates. A unit test fails if the committed files drift.
• CHANGELOG.md is release-please's (never hand-edit). The user-facing changelog is app/utils/changelog.ts → /changelog; see the changelog skill.
