Productized SaaS starter kit for the boring parts

What to build

A paid Next.js + Stripe + Drizzle SaaS starter kit that ships only the 'boring half' solo builders skip: pre-built onboarding flows, seat/plan-limit enforcement logic, populated empty-state screens with sample data, and transactional email flows (welcome, upgrade, dunning, trial-ending) wired to a provider like Resend.

Solo SaaS builders burn weeks reinventing onboarding, plan limits, empty states, and email flows instead of their core product — a focused, code-level boilerplate for just that plumbing is a sellable niche next to broader all-in-one starter kits.

Demand

Solo founders and indie hackers racing to ship a SaaS MVP want to skip the non-differentiating plumbing work; the pain is fresh enough to be posted and discussed right now in builder communities.

  First-person account of a solo builder implementing onboarding, plan limits, empty states, and email flows, framing them as the overlooked 'boring half' of SaaS development that costs real launch time.

• ShipFast / SaaS Pegasus / Supastarter boilerplate marketDemand

  Existing paid Next.js SaaS boilerplates (ShipFast, SaaS Pegasus, Supastarter) each charge $100-$300+ one-time, showing solo builders already pay for pre-built SaaS plumbing rather than building it themselves.

Stack

• Next.js
• Drizzle ORM
• Stripe Billing
• Resend (transactional email)
• Clerk or Auth.js
• PostgreSQL

Solo + AI difficulty

Easy to medium for one person with AI help: onboarding UI and empty states are straightforward frontend work, but seat/plan-limit enforcement and graceful billing degradation (webhooks, race conditions, downgrade edge cases) take real care to get correct. Realistic time-to-MVP is 3-5 weeks for a sellable v1 if scoped to one framework stack rather than multi-stack support.

Entry threshold

Low barrier: a single developer can assemble and polish this in 1-3 weeks using existing open-source pieces (Next.js, better-auth, Drizzle, Stripe); main cost is the time to productize and document, not capital or licences.

Counter-signals & risks

• Established Next.js/Stripe SaaS boilerplates already cover auth, billing, and onboarding, making differentiation hard for a new entrant focused on the same plumbing.

• Solo founders often prefer free or open-source starter templates over paid ones, which limits willingness to pay for a packaged solution.

• The underlying pain point is anecdotal from a single builder's blog post and Reddit thread, and may not generalize to a broad base of paying customers.
