summary
Lemonade builds t-env, an internal dev platform running Kubernetes plus Okteto, Pulumi and Grafana that gives each developer one or more personal copies of the system, deploys via production pipelines in minutes, and supports file sync, remote debugging and hot reload through the Octeto CLI. Launch causes a dramatic spike in PRs merged per week, adoption scales across hundreds of developers, and practical fixes include ephemeral environments sleeping by timezone to cut cloud costs while accepting a long‑term platform team commitment.
