Template Guides
Field notes on shipping Next.js SaaS templates: Stripe webhooks that survive production, Supabase RLS that holds under real load, App Router SEO patterns, AI/RAG pipelines, and pricing pages that convert. Practical, code-anchored writing — no recycled framework history.
Multi-tenant Next.js architecture with Postgres RLS
Workspaces as the tenant boundary, a workspace_id column on every row, and Postgres RLS as the enforcement layer so a missing WHERE clause in your code cannot leak data across tenants. The B2B architecture decision worth getting right on day one.
ShipFast vs Makerkit: honest 2026 comparison
Two serious Next.js boilerplates, two different buyers. ShipFast wins on community and solo-maker launch speed; Makerkit wins on multi-tenant depth and TypeScript discipline. A side-by-side on stack, billing, depth, and price, written without a favorite.
What is a SaaS boilerplate? (And when it actually saves you time)
A SaaS boilerplate is a pre-built codebase, auth, billing, database, landing, you buy as a starting point. It saves time when the stack and conventions match your product. It costs more than rolling your own when you fight them. A guide to deciding before you pay.
Best stack for shipping a SaaS in 2026
The default 2026 SaaS stack, Next.js 16, React 19, TypeScript strict, Postgres, Tailwind v4, Stripe or MoR, Vercel. Where the exotic alternatives earn their slot, and the stack debates that do not matter as much as the discourse implies.
Next.js vs Remix for a SaaS in 2026
Next.js wins by default in 2026, App Router, Server Components, the Vercel story, and ecosystem volume. Remix (now React Router v7) has real strengths in data loading and progressive enhancement. A five-minute decision tree on which to pick for your SaaS.
Building a ChatGPT clone with Next.js + Claude
A working chat product in Next.js 16 is three pieces, a streaming Route Handler, a React UI on the Vercel AI SDK, and a thread/messages schema. The hard parts are auth, persistence, and credit metering, not the model call. Written for engineers shipping their first AI product.
RAG starter kit: a guide to shipping retrieval in Next.js
A production RAG pipeline in Next.js is four steps, upload, chunk, embed, retrieve, backed by Postgres with pgvector. The cost shows up at chunking and retrieval quality. Auth and multi-tenant scoping matter as much as embeddings once you charge money.
next-intl tutorial: shipping a multilingual Next.js site
next-intl is the i18n library most App Router projects pick in 2026. Locale-prefixed routes, messages per language, middleware-based detection. The hard parts are hreflang, locale-aware canonicals, and keeping translations in sync, not the library API.
Why your Next.js 16 build crashes on a missing env var and a 5-line Proxy fix
Your production build fails with 'Missing API_KEY' but your runtime works fine. Here is why Next.js collects page data at build time, why naive fixes do not work, and the lazy Proxy pattern that ends it.
SAML SSO in Next.js: the enterprise checklist
SAML SSO unlocks the contracts your sales team cannot close without it. The work is correct IdP integration, SP- and IdP-initiated flows, and the audit trail procurement actually reads. Use BoxyHQ Jackson, WorkOS, or Stytch, do not parse the XML yourself.
Best Next.js SaaS boilerplate in 2026: an honest buyer's guide
ShipFast, Makerkit, Supastarter, and Boilerlykit compared on stack, billing, multi-tenant, AI, and price. Where each one leads, where each one lags, and how to pick without regret.
Template vs boilerplate for Next.js SaaS (2026)
When a paid starter saves you time, when it costs more than rolling your own, and what to audit in the repo before you commit.
Selling templates online: Paddle vs Stripe (and when both)
Merchant-of-record vs DIY taxes, chargebacks, and checkout UX. What actually changes for template sellers.
Deploy a Next.js SaaS template on Vercel without drama
Env groups, webhook URLs, preview vs production domains, and caching surprises that only show up under load.
Supabase Auth plus RLS: keep rows where they belong
How JWT claims, policies, and schema line up so one workspace never reads another's data by accident.
Next.js App Router auth that does not fight Server Components
Sessions in cookies, middleware timing, route handlers, and the refresh flow that stops mystery 401s.
Pricing pages that do not bury the lead
Plans, limits, annual toggle, and the microcopy around the button people stare at the longest.
Next.js technical SEO checklist (App Router)
Canonicals, metadata API, sitemap route, robots, OG images, and JSON-LD that matches what users actually see, plus a 2026 update on AI search (GEO) tactics.
Internal links that turn blog traffic into trials
Topic clusters, hub pages, and CTAs so search traffic stops dying on orphan posts.

Analytics, billing smoke tests, support paths, and the toggles people flip wrong between staging and prod.
