Cloud, Desktop or Server - which version of IUCLID is best for me?

IUCLID 6 is available in three different versions. These provide the same main functionalities, but are designed to cater to different sets of user requirements.

IUCLID 6 ECHA Cloud services
A IUCLID Cloud service is provided by the European Chemicals Agency (ECHA) for preparing REACH registration dossiers. Companies and their consultants are encouraged to use the cloud service as it means they no longer have to install IUCLID locally on a computer, but will have direct access to the latest version in a web browser – anytime, anywhere. The service comes with up to 1 GB of data storage, fully managed backups and dedicated helpdesk support, at no charge. Go to ECHA Cloud Services.

IUCLID 6 Desktop
In IUCLID 6 Desktop, IUCLID 6 runs on a single machine. One user accesses one database, with no network connection necessary. There can be more than one user account for the installation, but only one user uses the installation at a time. The database is integrated into the IUCLID 6 application. There is no need to install database software separately. The installation process, maintenance and upgrades are designed to be as simple as possible. This is aimed at SMEs, and those who simply want to try out the software.

IUCLID 6 Server
In IUCLID 6 Server, IUCLID 6 runs in an application server. A user connects to the application over a network using a client program that can be run on any machine that has network access to the server. Many users can access the same instance of the application and therefore the database, at the same time. Access to documents can be restricted per document, per user, and per groups of users. The database software can be installed separately from the IUCLID 6 application server and client(s). This type of installation is intended for use by larger companies and organisations.

IUCLID 6 Server is marked out from IUCLID 6 Desktop visually by having a grey ring around the orange icon.

The latest version of IUCLID 6 published for all users on this website is 3.16.1. The ECHA Cloud services users have access to version 3.21.0.
