We build AI products. Ours are already live.
vx-build is a small AI-first studio. We design, ship and operate our own software — an AI website builder, an AI app builder, and a diagnostic tool used by diesel technicians. The same team and the same stack are available for your build.
Tell us what you're building
A studio that ships its own software
Built, launched and operated in-house
Most agencies talk about AI. We run it in production. Everything we offer, we have already built for ourselves: a website builder that generates and hosts complete multi-page sites, an app builder that writes and deploys working web apps, and a diagnostics tool that ranks fault-code causes for diesel technicians. That means we are not learning on your budget. The architecture, the failure modes and the running costs are things we have already paid for once. We work in small, direct engagements — you talk to the people writing the code, not to an account manager.
Three products, in production
Not case studies — live software we designed, built and run.

caddisfly.ai
Describe a business in plain words and caddisfly generates a complete multi-page website — copy, layout and images — then publishes it on your own domain. It will also rebuild an existing site into a modern design from nothing but its URL.
- Multi-page sites with real navigation and themes
- Per-section AI editing and automatic SEO
- Plugins for CRM · store · bookings · courses · members · newsletters · chat
- Custom domains and hosting included
- Built on Cloudflare Workers · D1 · R2 — in English · Spanish · Portuguese

vx-build.ai
Describe an app and vx-build writes it, deploys it and runs it — live in about a minute. Not a demo on someone else’s server: every app gets its own isolated stack.
- A private SQL database per app with a visual studio to query it
- Passwordless email sign-in for your users
- Stripe checkout · transactional email · Telegram alerts
- API keys in an encrypted vault; one-click AI security review
- File storage · traffic charts · custom domains — in four languages

rigmedic.ai
A working tool for diesel technicians. Enter a fault code, a symptom or a VIN and RigMedic ranks the probable causes by real-world fix rates — then shows the matching service bulletins and the parts the job is likely to need.
- Covers both OBD-II and J1939 fault codes
- Probable causes ranked by real-world fix rates
- Matching technical service bulletins — VIN-aware where available
- A searchable fault-code library plus solved cases
- Published in English · Portuguese · Spanish
Where we can help
The work behind those three products, applied to yours.
AI products, end to end
From prompt design to a deployed product — architecture, model choice, interface, and the bill that comes with it.
Apps and internal tools
Customer portals, dashboards and the small internal tools that quietly keep a business running.
Websites that earn their keep
Fast, accessible marketing sites with real SEO, working forms and a CMS your team will actually use.
Edge infrastructure
Cloudflare Workers, D1, R2 and queues — low latency, low cost, and no servers to babysit.
AI you can operate
Model fallbacks, health monitoring and spend controls, so an outage or a price change is not an emergency.
Multilingual by default
Every product we run ships in three or four languages. Yours can too.
