The Coyne Labs tech stack — what we build on and why

Most agencies hide their tech stack. Coyne Labs publishes it. The stack is part of the product, and the client owns it at month 12. There are no secrets.

Frontend and framework

Next.js 14+ App Router with TypeScript — every site we build. Next.js gives us static rendering, incremental regeneration, and edge performance out of the box. TypeScript keeps the code base maintainable at scale.

Tailwind CSS — utility-first styling for speed and consistency. No bespoke CSS file per page. No theme drift.

Hosting

Vercel — static and edge hosting. Free tier for most client sites. Deployments tied to Git. Automatic SSL. Global CDN. Zero maintenance burden.

GoDaddy for domain registration only, never hosting. Domain stays at GoDaddy, nameservers point to Vercel.

Forms and lead capture

Server Actions + Zod validation + rate limiting + honeypot + Resend for email + optional Supabase for lead storage. Every form on every site has the full stack — not a plugin, not a third-party service. Leads arrive by email the moment they are submitted, and are optionally stored in a database the client owns.

Analytics

Vercel Analytics + Google Analytics 4. Real-time performance monitoring, conversion tracking, and historical reporting. Client owns the GA4 property.

SEO

Custom sitemap generation, structured data markup, robots.txt tuned for AI crawlers and search crawlers, Core Web Vitals compliance. Every site ships with SEO baked in, not bolted on later.

Security

Content Security Policy, secrets in environment variables only, automated dependency audits, route authentication where needed, rate limiting on all public endpoints. Phase 7b of every build.

Accessibility

WCAG 2.2 AA compliance — skip nav, focus management, semantic HTML, color contrast, touch target sizing, form labels. Not optional. Not an add-on.

Content management

Content lives in the Git repository as TypeScript files. Version controlled. Reviewable. Reproducible. No WordPress plugins, no headless CMS subscriptions, no database for content. Clients who want visual editing have options, but most prefer the reliability of code-based content.

Observability

Sentry for error tracking, uptime monitoring, and monthly anomaly review. Errors get caught before the client sees them. Monthly reports surface patterns that need attention.

What clients own at month 12

• —Full Next.js codebase, portable to any hosting provider
• —Full content library in plain text, portable to any CMS
• —Google Analytics property and data
• —Google Search Console property
• —Google Business Profile
• —Vercel project (client takes over billing if desired)
• —Domain registration
• —Resend and Supabase accounts (if used)
• —All lead data

There is no lock-in. Clients can leave Coyne Labs at any time and take the full operation with them.

Why this stack

It is the fastest-loading, most secure, most maintainable stack available for local service businesses. It is what I would build for my own businesses — because it is what I build for my own businesses. Coyne Commercial Group runs on this stack. So does every client site.

Why Coyne Labs

The stack is part of the value. The ownership model is part of the value. The reliability is part of the value. For more on the operating model, read the Coyne Labs difference. Or book a call and we will walk through exactly what the tech stack looks like for your build.
