Each Lime CRM Server on-premise release has a specific version of the library lime-crm included. To enable a matching release, you need to specify the correct version of lime-crm in your pyproject.toml file, e.g.:

lime-crm = "==1.6.1"

In the list of released on-premise versions, the version of the lime-crm can be found in parentheses of the version number.


Lime CRM 2020.2.245 (2.22.2) is built against lime-crm==2.22.2 as implied in the version number


Note that your solution is built for a specific version of Lime CRM. That means that every time you upgrade a server, you need to build the solution again. Otherwise, you might re-install the previous version of Lime CRM when installing the solution.

Follow these steps to install a solution:

  1. Download the wheelhouse of a solution from a github release (<solution-name>/releases) or a local dist folder (if built using lime-buildtools).

  2. Run the following command to install the solution on a Lime CRM server:

$ limefu solution install <solution-{solution-name}-{suffix}.tar.gz>

Finally, you have to restart every installed lime service such that the customizations in the solution is picked up by Lime CRM. After that, the solution is installed! 🎉

Configuring an On-Premise Installation

Environment configuration

The environment configuraiton config.yml is located in the <service dir> and differs depending on the type of service and platform.


Note that each service uses separate configuration files


Note that the config.yml file also can be named config.yaml. If both these files exist, the file with .yml suffix takes precedence.

The location for config.yml is %programdata%\Lundalogik\LIME Pro Server\<service name>\configs

Application configuration

For Windows On-Premise installations, the application-level configuration is expressed in the file %programdata%\Lundalogik\LIME Pro Server\application_config.yaml. If it does not already exist, just create it.


Unlike config.yml, the application_config.yaml file is shared by all services. That means that if you wish to add configuration for both the web server and the task handler, you only need to edit configuration once.

Run services debug mode

The Lime web server can be run in the command prompt rather than as a service. This is good when developing custom endpoints and custom limeobjects. The Lime web server can be started in debug mode, such that everytime you change your Python code, the server will be restarted. The web server will additionally only run the web server on one thread (useful if you wish to run a debugger in your code). Note that this feature only should be done when developing on your local machine! When you are done developing, remember to start your 'Lime CRM Webserver' service again.

  • Run services.msc and stop the Lime CRM Webserver service.

  • Right click and run the Limefu prompt on the desktop as Administrator. Type:


  • The loglevel can be configured in the config file for the webserver). They're also written to the server logs in %LIME_HOME_PATH%\LIME Pro Server\Web Server\logs.

  • To stop the server, press Ctrl+C (sometimes multiple presses are needed).

With event handlers, which are run with in a separate service, the same principle applies.

  • Run services.msc and stop the Lime CRM Event Handler service.

  • Right click and run the Limefu Command Prompt on the desktop as Administrator. Type:


  • The logs can be found in %LIME_HOME_PATH%\LIME Pro Server\Event Handler\logs.

Note: Always make sure that the corresponding service is stopped when running lime-webserver or lime-event-handler in Limefu!
