Twelve things you won't build again
Full authentication
Google OAuth and email/password, with verification, password reset, change password, and account deletion.
Stripe subscriptions
Checkout and the billing portal wired up, gating a real feature end to end.
CSV bulk import
Upload a CSV, validate row by row, batch-insert with per-row error reporting.
Real test suite
Backend unit tests, Vitest, and a full Playwright e2e run — wired into CI, not an afterthought.
Charts & metrics
An example dashboard with aggregate metric cards and a monthly chart.
Light & dark mode
Theme-aware components throughout, no flash on load.
Legal pages included
Terms of Service and Privacy Policy stubs, ready to fill in for your business.
SEO-ready
Per-page metadata, sitemap, robots.txt, and Open Graph tags out of the box.
Product analytics
PostHog ready with one environment variable — pageviews plus conversion events on the CTAs.
Rate limiting & pagination
Per-IP rate limiting and server-side pagination on the API.
Sentry monitoring
Optional error monitoring and tracing across the frontend and backend.
CI/CD pipeline
A staging → production GitHub Actions pipeline, off until you opt in.
Same price, same frontend
Which one should you buy?
Pick on how you want to write the backend. Everything above this line is identical in both.
Go template
Buy this if you want an explicit backend: typed queries with sqlc, a single binary, and no framework magic to unlearn.
