HONEST BOUNDARIES

What make1day does — and what it won't pretend to

We lay it out plainly: the left column is what's stable today; the right is what we know we don't do. No hidden clauses.

Stable today

Production-grade scaffold

Next.js 15 App Router + TypeScript + Tailwind that runs out of the box — not a demo toy.

Row-level security on by default

Supabase data is isolated by user/org at the schema level. Boundaries are built in, not bolted on later.

License-code distribution

After buyout you get license codes — activate per code, revoke anytime, with a transparent distribution log.

RAG knowledge base & multi-tenancy ready

Document Q&A and org isolation scaffolding are ready; wire in your data and ship.

Known limits

Won't write your business logic

make1day gives a production-ready skeleton. Your differentiation — domain model, core algorithm — is on you.

Won't pass merchant onboarding for you

An independent web SaaS has no app-store review, but payment providers do run merchant onboarding, KYC and compliance checks, and they alone decide the outcome. The starter ships legal-page templates and the webhook wiring — not legal advice or an approval.

Won't cover unlimited quotas

AI calls and build counts bill against your own keys and quotas. make1day doesn't silently back infinite usage.

Won't auto-chase every framework major

Major upgrades arrive as drift-safe patches through the Care plan — not as real-time auto-upgrades.

REAL LAUNCH PITFALLS

The pits that actually sink launches — named upfront

Templates look great in demos. These are the holes make1day helps you fill early — and where indie devs most often crash on launch.

Webhook

Payment webhook reconciliation

Stripe/Creem webhooks drop events, duplicate them, fail signature checks. make1day ships idempotent handling and retry — your ledger stays correct.

RLS

Row-level security & permissions

The most overlooked breach: one bad policy lets user A read user B's data. We default to least privilege with auditable policy templates.

License

License distribution & activation

Rolling your own license check, abuse protection, and revocation is another deep pit. make1day's license-code system is ready, with a queryable distribution log.

Drift

Dependency & version drift

Ignore it for three months and one upgrade breaks everything. The Care plan merges patches into your fork drift-safely — no merging from scratch.

CAPABILITY MATRIX

What we lead with, what we keep quiet

We put differentiators up front; commodity SaaS features aren't hyped or padded — they sit in the footnote.

Differentiators (production-grade boundaries)

RAG knowledge base

Runnable doc ingest → retrieve → cite Q&A. Wire in your data and ship.

Multi-tenancy

Org/workspace isolation scaffolding with helpers to extend per-customer data.

Row-level security (RLS)

Supabase least-privilege policies by default — authorization bugs blocked at design time.

License-code distribution

Buyout license codes: generate, activate, revoke — with a transparent distribution log.

Commodity included (no hype, works out of the box)

Auth (email + OAuth)Subscription billing (Stripe/Creem + webhooks)1-click deploy (Vercel/Cloudflare)Observability (structured logs + error boundary)

The commodity items above are production-grade — but we don't sell them as features. They're the entry ticket, not your product.

THEME SYSTEM

Not another UI kit — a design asset you can take with you

make1day's theme system exports reusable design assets, not hardcoded styles locked inside a project you can't touch.

Reusable CSS tokens: Colors, spacing and type scale ship as CSS variables (design tokens). Change once, apply everywhere — reuse them in other projects.
design.md spec file: Auto-generated design.md documents design decisions, token mappings and component conventions — so you and your AI coding assistant extend the UI consistently.

FAQ

Questions indie founders actually ask

Everything about using make1day to ship your AI SaaS — auth, checkout, AI, deployment, white-labelling and licensing, including the limits we do not hide.

Does the starter include a user dashboard and an admin dashboard?+

Yes — two separate consoles ship by default.

`/account` is the signed-in user area: profile, subscription, issued license keys, settings.
`/admin` is the operator area: users, licenses, traffic, runtime status.

Both are five-language (EN/ZH/JA/FR/DE).

In the Builder, account and admin are toggleable features. Unchecking one removes its entire route tree from the ZIP, and navigation plus post-login redirects are rewritten so no dead links remain.

Both are writable:

PATCH /api/profile edits the signed-in profile
PATCH /api/admin/users manages roles (admin only)
/api/billing/portal opens the provider billing portal
/admin/tickets changes ticket status

RBAC tables (0004_profiles_rbac.sql) and org tables (0007_orgs.sql) ship with every build.

Protect `/admin` before deploying: ADMIN_USER / ADMIN_PASSWORD create an operator account that signs in through /admin's own form with an HMAC-signed session cookie; with no credentials configured, the console stays closed in every environment. A Supabase user with an admin/staff role — or an ADMIN_EMAILS allowlist entry — is accepted too.

How do I get my license key after paying?+

The full source ZIP requires a license — a Buyout license ($99) or an active Care plan.

After a paid webhook, the key is emailed to the checkout address automatically, idempotent per issued key. A failed send is queued in mail_outbox and retried by a cron endpoint.

You can also:

Sign in with the email you paid with and open /account/licenses
Paste an offline key into /license
Use the claim form on /license to request a re-send if you checked out as a guest or used a different login email

Real delivery still requires configuring a mail provider and a host scheduler — those are deployment steps, not missing code.

No license yet? Download a free, source-free preview: the complete file inventory of your build plus the design tokens (no source code). The gate protects this site only; the project you download ships with it disabled.

What is a Next.js SaaS boilerplate?+

It's a prebuilt, production-grade starting point for a SaaS: authentication, database, billing, an admin area and often a working AI feature.

The point is to skip 4–8 weeks of commodity setup and build only what makes your product unique.

How do I build a SaaS with Next.js?+

Start from a configurable starter such as make1day.
Set your env vars — Supabase, a payment gateway, an AI key.
Pick your stack in the Builder.
Download the generated scaffold and deploy to Vercel or Cloudflare.

Most founders reach a launchable MVP in days, not months.

Does make1day include subscription billing and Stripe support?+

Yes. The generated app ships with hosted checkout (Waffo Pancake by default) and webhook-synced plan status.

In the Builder you can switch to Stripe, Creem, PayPal, Lemon Squeezy or Waffo Acquiring — checkout and webhook routes are provider-agnostic, and only the selected adapter ships in the ZIP.

Trial periods are configured in your payment provider's dashboard, not hardcoded in the scaffold.
