Quick start

This guide will get your first QuestDB instance running.

As the goal is to, well, start quickly, we'll presume defaults.

Once running, we'll provide guides for inserting data, configuration and production hosting.

QuestDB already running? Jump ahead! Select a first-party client or ingest method.

Install QuestDB

Choose from the following options:


To use Docker, one must have Docker. You can installation find guides for your platform on the official documentation.

Once Docker is installed, you will need to pull QuestDB's image from Docker Hub and create a container:

docker run \
-p 9000:9000 -p 9009:9009 -p 8812:8812 -p 9003:9003 \

For deeper instructions, see the Docker deployment guide.


To install QuestDB via Homebrew, run the following command:

brew install questdb

On macOS, the location of the root directory of QuestDB and server configuration files depending on the chip:

  • Apple Silicon (M1/M2/M*) chip: /opt/homebrew/var/questdb

  • Intel chip: /usr/local/var/questdb


Download and run QuestDB via binaries.

Select your platform of choice:

Download the binary:


This package does not embed Java.

Use this if there is no package for your platform, such as ARM Linux.

Requires local Java 17.

To check your installed version:

java -version

If you do not have Java, install one of the following:

  • AdoptOpenJDK
  • Amazon Corretto
  • OpenJDK
  • Oracle Java

Other Java distributions might work but are not tested.

For environment variable, point JAVA_HOME to your Java 17 installation folder.

Run QuestDB

./questdb.sh [start|stop|status] [-d dir] [-f] [-n] [-t tag]
-dExpects a dir directory value which is a folder that will be used as QuestDB's root directory. For more information and the default values, see the default root section below.
-tExpects a tag string value which will be as a tag for the service. This option allows users to run several QuestDB services and manage them separately. If this option is omitted, the default tag will be questdb.
-fForce re-deploying the Web Console. Without this option, the Web Console is cached and deployed only when missing.
-nDo not respond to the HUP signal. This keeps QuestDB alive after you close the terminal window where you started it.
