Quest is a desktop user interface to common postgress wire protocol-compatible databases such as:

• QuestDB
• Postgres

• <your system's gradle command> wrapper: regenerates the gradle scaffolding, eg. gradle whapper, so that then you can use the subsequent commands.
• build: ./gradlew clean build

• windows: gradlew.bat run
• mac/linux: ./gradlew run

After the build command completes, you will find a zip file in build/distributions/:

• cd build/distributions
• unzip quest-*.zip
• cd quest-<version>
• bin/quest (or bin\quest.bat in windows)
