Deploy a Next.js SaaS template on Vercel without drama

Green builds still fail when prod URLs, secrets, and Stripe webhooks do not line up. This is the short checklist we run before sharing a link with paying users.

Budget about half an hour on Vercel plus your providers.

1) Set your canonical URL

Make sure your app knows its public URL (for share cards, emails, and redirects). In Boilerlykit templates this is typically an env like:

• NEXT_PUBLIC_APP_URL

2) Configure environment variables (and validate them)

Your “minimum viable env” usually includes:

• Auth provider keys
• Database URL + service role key (server-only)
• Billing/webhook secrets (server-only)
• Email provider keys (if you send transactional emails)

If your template has a setup page, use it. If not, create a small “env validation” route early.

3) Webhooks: point them at production

The #1 billing incident: webhooks still pointing at staging.

Checklist:

• Update webhook endpoints to the production domain
• Verify signature secrets are set
• Make handlers idempotent
• Log webhook processing failures

4) Domains and redirects

Decide:

• Will you use www or apex?
• Do you redirect HTTP → HTTPS?
• Do you redirect the other hostname to the canonical one?

Consistency matters for SEO and cookie/session behavior.

5) Caching and revalidation

If you use ISR (revalidate) for docs/blog:

• Pick a revalidation interval that matches your content cadence
• Confirm dynamic pages generate correct metadata
• Avoid caching user-specific pages

6) Observability (before you need it)

At a minimum:

• Capture server errors with stack traces
• Monitor webhook failures
• Track the conversion funnel (visit → template page → checkout)

7) Do a “real user” pass

Open a private window and run:

• Sign up / sign in
• Purchase flow
• Upgrade/downgrade (if applicable)
• Password reset (if applicable)
• A core feature flow end-to-end

For a deploy-ready minimal shell, SaaSForge Starter is the fastest path: landing + blog + docs + theme, zero billing/DB dependencies to configure on first deploy. For the full SaaS path with billing and workspaces, see SaaSForge Core or SaaSForge AI and their docs (Starter deploy, AI deploy).
