  • Analyze and manage cloud cost, usage, security, and governance in one place.
  • Control your usage and create visibility across all used services to achieve maximum cost-effectiveness.
  • Detect potential vulnerabilities that could put your cloud environment at risk.
  • Get a deep understanding of how you spend on the AWS, GCP, OVH, DigitalOcean and Azure.



Become a backer and show your support to our open source project.


Does your company use Komiser? Ask your manager or marketing team if your company would be interested in supporting our project. Support will allow the maintainers to dedicate more time for maintenance and new features for everyone. Also, your company's logo will show on GitHub and on our site - who doesn't want a little extra exposure? Here's the info.


Below are the available downloads for the latest version of Komiser (2.4.0). Please download the proper package for your operating system and architecture.


wget https://cli.komiser.io/2.4.0/linux/komiser


wget https://cli.komiser.io/2.4.0/windows/komiser

Mac OS X:

wget https://cli.komiser.io/2.4.0/osx/komiser

Note: make sure to add the execution permission to Komiser chmod +x komiser

brew tap komiserio/komiser
brew install komiser


docker run -d -p 3000:3000 -e AWS_ACCESS_KEY_ID="" -e AWS_SECRET_ACCESS_KEY="" -e AWS_DEFAULT_REGION="" --name komiser mlabouardy/komiser:2.4.0

How to use


  • Create an IAM user with the following IAM policy:
wget https://komiser.s3.amazonaws.com/policy.json
  • Add your Access Key ID and Secret Access Key to ~/.aws/credentials using this format
aws_access_key_id = <access key id>
aws_secret_access_key = <secret access key>
region = <AWS region>
  • That should be it. Try out the following from your command prompt to start the server:
komiser start --port 3000

You can also use Redis as a caching server:

komiser start --port 3000 --redis localhost:6379 --duration 30
  • Point your browser to http://localhost:3000

Multiple AWS Accounts Support

Komiser support multiple AWS accounts through named profiles that are stored in the config and credentials files. You can configure additional profiles by using aws configure with the --profile option, or by adding entries to the config and credentials files.

The following example shows a credentials file with 3 profiles (production, staging & sandbox accounts):




To enable multiple AWS accounts feature, add the --multiple option to Komiser:

komiser start --port 3000 --redis localhost:6379 --duration 30 --multiple
  • If you point your browser to http://localhost:3000, you should be able to see your accounts:


  • Create a service account with Viewer permission, see Creating and managing service accounts docs.

  • Enable the below APIs for your project through GCP Console, gcloud or using the Service Usage API. You can find out more about these options in Enabling an API in your GCP project docs.

    • appengine.googleapis.com
    • bigquery-json.googleapis.com
    • compute.googleapis.com
    • cloudfunctions.googleapis.com
    • container.googleapis.com
    • cloudresourcemanager.googleapis.com
    • cloudkms.googleapis.com
    • dns.googleapis.com
    • dataflow.googleapis.com
    • dataproc.googleapis.com
    • iam.googleapis.com
    • monitoring.googleapis.com
    • pubsub.googleapis.com
    • redis.googleapis.com
    • serviceusage.googleapis.com
    • storage-api.googleapis.com
    • sqladmin.googleapis.com
  • To analyze and optimize the infrastructure cost, you need to export your daily cost to BigQuery, see Export Billing to BigQuery docs.

  • Provide authentication credentials to your application code by setting the environment variable GOOGLE_APPLICATION_CREDENTIALS:

  • That should be it. Try out the following from your command prompt to start the server:
komiser start --port 3000 --dataset project-id.dataset-name.table-name
  • Point your browser to http://localhost:3000


  • Create an API application from here.

  • This CLI will first look for direct instanciation parameters then OVH_ENDPOINT, OVH_APPLICATION_KEY, OVH_APPLICATION_SECRET and OVH_CONSUMER_KEY environment variables. If either of these parameter is not provided, it will look for a configuration file of the form:

; general configuration: default endpoint

; configuration specific to 'ovh-eu' endpoint
  • The CLI will successively attempt to locate this configuration file in

    • Current working directory: ./ovh.conf
    • Current user's home directory ~/.ovh.conf
    • System wide configuration /etc/ovh.conf
  • If you point your browser to http://localhost:3000, you should be able to see your projects:


  • To generate a personal access token, log in to the DigitalOcean Control Panel.

  • Click the API link in the main navigation, In the Personal access tokens section, click the Generate New Token button.

  • Create a ready-only scope token. When you click Generate Token, your token will be generated.

  • Set DIGITALOCEAN_ACCESS_TOKEN environment variable:

  • If you point your browser to http://localhost:3000, you should be able to see your projects:


komiser start [OPTIONS]
   --port value, -p value      Server port (default: 3000)
   --duration value, -d value  Cache expiration time (default: 30 minutes)
   --redis value, -r value     Redis server (localhost:6379)
   --dataset value, -ds value  BigQuery dataset name (project-id.dataset-name.table-name)
   --multiple, -m              Enable multiple AWS accounts feature

Configuring Credentials

When using the CLI with AWS, you'll generally need your AWS credentials to authenticate with AWS services. Komiser supports multiple methods of supporting these credentials. By default the CLI will source credentials automatically from its default credential chain.

  • Environment Credentials - Set of environment variables that are useful when sub processes are created for specific roles.

  • Shared Credentials file (~/.aws/credentials) - This file stores your credentials based on a profile name and is useful for local development.

  • EC2 Instance Role Credentials - Use EC2 Instance Role to assign credentials to application running on an EC2 instance. This removes the need to manage credential files in production.

When using the CLI with GCP, Komiser checks to see if the environment variable GOOGLE_APPLICATION_CREDENTIALS is set. If not an error occurs.
