The 2026 SaaS Starter Kit:
A Next.js SaaS Starter Kit & Boilerplate that eliminates tool chaos.

Stop duct-taping tools.

Start building your product.

Early-stage SaaS founders lose weeks stitching together billing, CRM, email, and support tools.

Multiple logins, broken integrations, scattered customer data — all before product–market fit.

There’s a simpler way to run a SaaS without the tool chaos.

The Stack: Next.js 15 (App Router) • Tailwind CSS • Outseta Script / Auth Widgets • Stripe Payments • Zero-Config Deployment.

3 Steps to a Fully Functional SaaS Stack

Step 1: Connect Stripe

Link your Stripe account to Outseta in one click.

Step 2: Inject the Script

Add the integration snippet to your layout.tsx file.

Step 3: Launch

Implementation is as simple as a single script tag.

// Outseta + Next.js Integration

import Script from 'next/script'

<Script

src="https://your-domain.outseta.com/js/site.js"

The Problem With the Typical SaaS Tool Stack

Comparison of expensive fragmented SaaS stack with multiple logins

Cost: $250+/month

Setup: 5 different logins, API integrations, constant data syncing issues.

Result: Distracted founder, fragmented customer data.

Outseta all-in-one SaaS dashboard with billing and CRM included

Cost: From $37/month

Setup: One login, zero integrations. Works "out of the box."

Result: Focused founder, unified view of every customer.

Common Questions

**"I already use Stripe. Can I still use Outseta?"**

Yes—Outseta is built on Stripe. Your existing Stripe account connects

in one click. No migration required.

**"What if I outgrow this?"**

Outseta scales to $1M+ ARR companies. If you eventually need enterprise

tools, you can migrate—but most founders don't need to.

**"Does this replace my entire stack?"**

For most pre-PMF SaaS companies: yes. If you have complex needs

(custom integrations, enterprise features), check the full review for limitations.

*Is this a GitHub repo or a hosted service?**

It’s both. Outseta provides the heavy-lifting (Auth, Billing, CRM) via a simple script integration, allowing you to keep your Next.js repository clean and focused on your core product features instead of 5,000 lines of boilerplate 'plumbing' code.
