Our toolkit
The stack we compose for you.
Every UWC project is built on the same set of carefully chosen tools — picked for reliability, ownership, and fit with the kind of work founder-owned businesses, solopreneurs, and small businesses actually do.
Code lives on your GitHub. Payments go through your Stripe. Email runs on your Resend domain. Hosting bills go to your Cloudflare account when you're ready. We compose; you own.
Infrastructure
Cloudflare
Pages, Workers, D1, R2 — every site we ship runs on the edge.
Fly.io
Postgres + Django for app projects. Region-flexible, scale-on-demand.
Hetzner
Long-running app projects when Fly is the wrong fit.
GitHub
Code lives on your account. You own the repo from day one.
AI + agents
Anthropic
Claude — the model behind every agent and the build pipeline.
Claude Code
Headless build dispatch via GitHub Actions. PRs land for human review.
MCP
Model Context Protocol — agents read your portal, schema, and reports.
Atlas Cloud
Image generation for marketing surfaces, under composite-illustration discipline.
DeepSeek
V4 with caching for cost-aware routine drafts where Claude is overkill.
OpenAI
Backup model where Claude isn't the right fit. Chosen on a per-task basis.
Payments + email
Stripe
Checkout, invoices, subscriptions. Connected to your Stripe account, not ours.
Resend
Transactional + broadcast email. Inbound webhook ingests replies into the portal.
OAuth for portal sign-in, Maps where useful, Workspace integration on retainer.
Frontend + content
Astro
Static + island-driven sites. Fast by default, no JS shipped you didn't ask for.
React
For the islands that need state. Forms, dashboards, interactive widgets.
Tailwind
Design tokens locked to your brand. No untraceable CSS.
Keystatic
Git-backed CMS for blogs and case studies. You edit, you push.
No paid affiliations with any of these vendors. We pick the right tool for the job and tell you when something on this list is the wrong fit for what you're building.
