Introducing VelocityKit: The Production-Ready SaaS Starter for AI-Native Founders

We're excited to launch VelocityKit—a production-ready SaaS starter kit designed for founders who want to ship fast without sacrificing quality.

The Problem with Starting a SaaS

Every SaaS application needs the same foundation: authentication, billing, email, analytics, and a database with proper security. You can build this yourself, but it's repetitive work. And grabbing random boilerplates often means inheriting technical debt and questionable patterns.

We built VelocityKit because this setup work is tedious, not hard:

• Auth: You know how to do it, but there are a dozen decisions to make and edge cases to handle
• Billing: Stripe's API is good, but webhook handling and subscription states have gotchas
• The rest: Analytics, email, rate limiting, RLS policies—all straightforward, all time-consuming

None of this is complex. It's just work you've done before and would rather skip.

What VelocityKit Includes

VelocityKit ships with everything you need to launch a real SaaS:

Authentication & Authorization

• Email/password and social login via Supabase Auth
• Multi-factor authentication support
• Account-scoped data with Row Level Security
• Session management and refresh

Billing & Subscriptions

• Stripe Checkout for payment collection
• Customer Portal for self-service management
• Webhook handling for subscription lifecycle
• Free, Pro, and custom tier support

Analytics & Insights

• PostHog integration for product analytics
• Feature flags for gradual rollouts
• LLM cost tracking for AI features
• User behavior insights

Developer Experience

• Next.js 16 with App Router and Server Components
• TypeScript with strict mode
• shadcn/ui components with Tailwind CSS
• AI-optimized workflow with Claude Code support

Built for the AI Era

What sets VelocityKit apart is our focus on AI-native development:

AI-Optimized Structure. The codebase is organized with clear patterns and comprehensive documentation that AI assistants can understand and extend safely.

LLM Cost Tracking. Built-in analytics for monitoring token usage and AI spending—essential for any product with AI features.

Claude Code Integration. CLAUDE.md provides context for AI assistants, and docs/prompts contains templates for common tasks.

Getting Started

After purchase, you get access to the VelocityKit GitHub repository. Use it as a template to create your own private repo, then:

git clone https://github.com/your-username/your-new-repo
cd your-new-repo
pnpm install
pnpm onboard

The interactive setup wizard guides you through:

1. Configuring your branding (name, tagline, colors)
2. Connecting Supabase, Stripe, PostHog, and Resend
3. Creating your subscription products via the Stripe API
4. Validating all integrations

Then run pnpm dev and start building your product. The code is yours—no ongoing fees or licenses to worry about.

Who Is This For?

VelocityKit is ideal for:

• Solo founders who want enterprise-quality infrastructure without the overhead
• Small teams who need to ship fast and iterate quickly
• AI-native builders who use Claude Code or similar tools
• Experienced developers who know what good patterns look like

What's Next

We're continuously improving VelocityKit based on real-world usage:

• Team and organization support
• Additional payment providers
• More AI feature examples
• Enhanced analytics dashboards
