Custom web engineering for platforms and tools.
When a project outgrows a site builder, Design X Develop builds it in code: Astro and Next.js sites, React frontends, internal tools, and services on Cloudflare Workers, written in TypeScript.
This site is an example — a static Astro build served by a Cloudflare Worker. The studio also publishes open-source developer tools and automation on GitHub.
What’s included
- 01Marketing sites and web platforms in Astro and Next.js
- 02React frontends and component-based design systems
- 03Cloudflare Workers, R2 storage, and edge asset delivery
- 04Internal tools, admin interfaces, and booking or intake flows
- 05Developer tools and command-line utilities
- 06CI, automation, and LLM-assisted engineering workflows
- 07Performance, accessibility, and cleanup of inherited code
How an engagement runs
- 01Discovery call. A short call to understand the project, the team, and what is in the way.
- 02Proposal. A written proposal with scope, deliverables, and price.
- 03Contract and deposit. A signed contract and a deposit invoice start the work.
- 04Build and review. Work ships to a review link as it is built, so feedback happens on the real thing.
- 05Launch. DNS, redirects, tracking, and forms are checked before and after go-live.
- 06Post-launch. A check-in after launch, then an optional maintenance retainer.

Questions
Which stack does Design X Develop use?
TypeScript throughout: Astro and Next.js for sites, React for application frontends, Cloudflare Workers and R2 at the edge, PostgreSQL for data, and Playwright and GitHub Actions for testing and automation.
Should we use Webflow or a coded site?
Webflow fits marketing sites that a non-technical team edits every week. A coded site fits when you need custom logic, application features, tight performance budgets, or full ownership of the code. DXD builds both and will recommend one after a discovery call.
Can you take over a codebase someone else started?
Yes. Taking over an inherited codebase — auditing it, fixing what blocks the team, and making it maintainable — is one of the most common ways engagements start.
