k6-gui is a Flask web app that runs both test types from the browser: k6 load tests via docker compose run, and Playwright browser tests via docker compose exec into the long-running playwright-runner container (Monaco editor, real-time log streaming, HTML reports for both). See terraform/modules/ec2-k6/templates/k6-gui/README.md for details.
