# Nextrey s.r.o.
> Software studio in the Czech Republic. We design and build custom software: web apps, SaaS products, mobile apps and AI features. We maintain them after launch. Building for clients since 2023.

Native Markdown exports live at parallel `.md` URLs (e.g. `/about.md`, `/blog/slug.md`). Humans use the HTML pages; agents should fetch the `.md` siblings.

Nextrey takes software from idea to production: architecture, design, frontend and backend, databases, integrations, deployment and ongoing maintenance. Optional add-ons include product policies written with attorney partners, app store and deploy help, SEO and content, security testing, and ops work such as logs and reports. These are not included by default. We build for clients targeting any market, not only Europe. Being an EU company means we can handle GDPR and EU requirements when it applies. We also run our own SaaS product in production. Default stack: Next.js, TypeScript, PostgreSQL, Redis, but we fit the tools to the job.
