SaaS Full-Stack Boilerplates: A Buyer's Guide

What should you check before choosing a SaaS boilerplate?

Every kit in this category promises to remove the weeks of plumbing that authentication, payments and email cost a solo founder, but the kits solve different problems for different teams. Before opening a demo, decide on five things: which language and framework your team already knows, whether the product needs multi-tenant team accounts from day one, whether billing has to arrive pre-wired or you're comfortable adding it later, what a one-time license actually costs against your budget, and how much you'll depend on the maintainer for future updates and documentation.

Framework fit is the first filter, because it decides everything downstream. According to their own pages, ShipFast and Makerkit both target Next.js, SaaS Pegasus is Django-only, and Wave is built on Laravel. Supastarter is the outlier: it ships parallel Next.js and Nuxt starters on a shared architecture, which makes it one of the few options in this category for teams committed to Vue rather than React. If your team already knows Python or PHP, a Next.js kit is the wrong starting point regardless of its feature list.

Team accounts are the second filter. Makerkit's page describes multi-tenant team accounts, role-based permissions and a super-admin panel built into a Turborepo monorepo, and its own limitations note that same monorepo has a real learning curve. ShipFast's listed limitations state plainly that multi-tenancy, roles and permissions are not in the box, since the kit favors a simple shell you bolt features onto. For a B2B product where teams and roles matter from launch, that single difference decides which kit is worth its price, independent of the framework question.

Free and open-source vs paid: what actually changes?

Two kits in this category cost nothing. Open SaaS is described as completely free and open-source, MIT-licensed, built on the Wasp full-stack framework with React and Node.js underneath. Wave, a Laravel starter from DevDojo, is also free and MIT-licensed. Both cover the same core checklist as the paid kits — authentication, subscription billing, an admin dashboard — without a purchase, which raises the real question in this category: what does paying $199 to $299 one-time actually buy over a free, MIT-licensed kit?

Mostly it buys pace of updates and support. Makerkit's page describes continuous updates and 400+ pages of documentation, plus direct support from the creator in Discord, alongside a listed price from $299 one-time; its live page separately advertises lifetime access at $349. SaaS Pegasus, at $249 with per-project licensing, has a maintainer who publishes changelogs and migration guides on every release. ShipFast, from $199 one-time, leans on a large existing customer base so that most integration problems have already been answered in its community Discord.

The free options have real trade-offs. Open SaaS ties you to the Wasp framework rather than plain Next.js or Node, which its own limitations describe as a smaller ecosystem and hiring pool, with an eject later meaning a rewrite. Wave's limitations note it supports individual subscribers, not multi-tenant team accounts, and that community support is the only channel, since DevDojo's paid attention goes to its commercial products first. Free removes the price barrier, not the architecture decision.

Which stack fits: Next.js, Django, Laravel or Node.js?

Next.js is the most crowded stack in this category. ShipFast ships as a plain Next.js App Router project with Tailwind and DaisyUI and database adapters for MongoDB or Supabase, per its page. Makerkit offers Next.js and React Router starters in a Turborepo monorepo with Supabase, Drizzle or Prisma. Supastarter also targets Next.js, alongside its Nuxt starter, on a shared architecture. Three different kits, three different opinions about what a production Next.js SaaS should look like beyond the framework choice itself.

Outside Next.js, the category has one option per stack. SaaS Pegasus is the Django kit: instead of a static repo, its configurator lets you choose React, HTMX or plain templates, Postgres, Docker and Celery, then generates a codebase containing only those choices. Wave is the Laravel kit, rewritten in its v3 onto current Laravel with Folio and Volt. Open SaaS is React plus Node.js, but compiled through the Wasp DSL rather than hand-wired — a different mental model from the other five kits even though the output is JavaScript.

For frameworks not covered by a dedicated SaaS kit in this list, the broader catalogue is the next stop rather than forcing a framework mismatch onto a kit that assumes something else. General Next.js and React starters, including ones outside the SaaS-specific category, live under Next.js & React. Readers evaluating a framework this category skips entirely, such as Angular, can check Is there a good Angular SaaS boilerplate? for what actually exists outside this list of six.

Does billing come already wired, or do you add it yourself?

Billing is wired into every kit here, but the providers differ. ShipFast's page lists Stripe payments alongside magic-link and social auth. Makerkit offers per-team billing through Stripe or Lemon Squeezy. Open SaaS's live page states it has pre-configured checkout and webhooks for Stripe, Polar.sh and Lemon Squeezy, so you choose a provider rather than integrate one from scratch. None of this is generic advice: Stripe's own billing documentation covers subscriptions, invoicing and usage-based pricing that any of these kits are wrapping for you.

SaaS Pegasus wires Stripe subscriptions together with team invitations and background jobs via Celery, so billing events can trigger asynchronous work rather than blocking a request. Supastarter's page lists payments alongside organizations and internationalization as core, pre-solved pieces, with localized pricing described as first-class rather than added later. Wave bundles subscriptions and billing with its Filament-based admin panel, so a subscriber's plan and status are visible from the same screen an admin already uses.

The catch across every paid kit is the same: heavy customization of the built-in billing flow generally means maintaining your own fork from that point on, as Supastarter's own limitations note. If your pricing model is a simple monthly subscription, wired billing saves real time; if you need a pricing model none of these kits anticipated, budget for divergence from the base kit regardless of which one you start from. General auth-and-payments options outside this category are grouped at Auth & Payments.

What's in the category, and how do the filters help you narrow it down?

The category page for SaaS Full-Stack lists boilerplates and starter kits, openly labelled as open-source or paid, with filter buttons across the top for related categories: Next.js, React, Mobile & Native, Landing & Marketing, AI Apps, E-commerce, Browser Extensions, Backend & API, Auth & Payments and Dev Tooling, according to the live category page. Each filter narrows the list to kits tagged with that trait rather than requiring you to read every card.

Beyond the six kits detailed above, the same category page surfaces others worth knowing by name. Gravity is a paid Node.js and React kit with multi-tenant accounts, a REST API with token auth, an admin dashboard with user impersonation, and a scaffolding CLI for one codebase across web and mobile. Skipzero is a paid, from-€99 Next.js kit built specifically for founders working with AI coding agents, bundling auth, billing, access, email, an app shell, tests and agent instructions. Bullet Train is an open-source Rails framework with teams, invitations, roles and a scaffolding generator, MIT core with paid pro modules; Epic Stack is Kent C. Dodds's opinionated open-source full-stack starter.

Lined up side by side, the six kits with full detail in this guide split cleanly on stack, price and license, which is usually the fastest way to eliminate most of the list before reading a single doc page.

What mistakes do buyers make when picking a SaaS starter?

The most common mistake is buying for the demo instead of the limitation list. ShipFast's own page is explicit that multi-tenancy, roles, permissions and tests are not included, yet teams building B2B products from day one sometimes discover this only after paying $199. Reading the limitations section before the features section would catch this in minutes.

The second mistake is picking free without checking the framework lock-in. Open SaaS is a genuinely complete, MIT-licensed kit, but it compiles through the Wasp DSL rather than plain Next.js or Node, and its own limitations note that ejecting later means a rewrite, with a smaller ecosystem and hiring pool than Next.js. That trade-off is worth making deliberately, not discovering after months of building on Wasp-specific patterns.

The third mistake is assuming heavy customization is free just because the base kit is. Supastarter, Makerkit and the other paid kits all note, in their own limitations, that deeply customizing the built-in billing or auth flows generally means maintaining your own fork of the kit going forward. Budget that maintenance cost at purchase time, not after the fork has diverged. For a broader set of first scaffolds beyond this category, Is create-t3-app free? covers a free CLI alternative that starts from a narrower base.
