Docker

Containers & Dev Environments · Commercial / Open Source (Docker Engine: Apache-2.0; Desktop subscription terms apply)

Standard container tooling for packaging apps and dependencies into immutable images, ensuring consistent behavior across dev, CI, and production.

We use Docker for local service orchestration (Compose), hermetic builds, and CI pipelines; images can be deployed to managed platforms or orchestrators when serverless isn’t a fit.

How We Use It

  • Reproducible local environments and parity with CI/production
  • Containerized services and dependencies for development (DBs, queues, caches)
  • Portable deployment artifacts for servers, Kubernetes, and CI pipelines

Backend & Runtime

Why this matters: Choosing the right runtime and hosting improves reliability, security, and developer velocity from day one. We choose runtimes and hosting that balance security, developer experience, and performance. Our defaults favor fast iteration locally and reliability in production, with growing adoption of secure-by-default platforms. Preferred defaults: Bun for local dev, Node.js for production, Vercel for hosting and edge.
