    Run-Time Licences

    for the deployment of applications

    A Run-Time Licence is necessary (in addition to a Commercial Developer Licence) if:

    • Dyalog is used to implement multi-user applications (multi-user applications are defined as applications where the same data is shared by or exchanged between two or more users).
    • Dyalog is used as a platform for applications that are distributed outside the organisation that holds the Dyalog Developer Licence.

    If Dyalog is used to develop educational tools or applications sold to non-profit environments, then an appropriate low-cost licence can be negotiated with Dyalog Ltd.

    A range of different run-time licences are available; contact us if none of these meets your specific needs.

    Server/Processor Run-Time Licences

    for sharing applications

    A Server Run-Time Licence is charged by the number of users while a Processor Run-Time Licence is charged by the number of CPU cores (irrespective of how many cores are used to run the Dyalog-based applications). It includes access to upgrades and support.

    Generally, a Server Run-Time Licence is better suited for large or complex applications while Processor Run-Time Licences are more economical for lightweight applications (few CPU resources) that have a large user base.

    Server Run-Time Licences32-bit64-bit
    Up to 20 users (cost per annum) £750 £1,125
    Up to 50 users (cost per annum) £1,500 £2,250

    Royalty-Based Run-Time Licences

    for the exploration of new markets

    A royalty-based fee is well suited for the exploration of new markets as it reduces the licence investment. It is also beneficial for consultancies and software vendors who need to be up-to-date on Dyalog versions and platforms.

    A Royalty-Based Licence costs 2% of all revenue generated by sales, consulting and support of applications using Dyalog and is usually paid periodically in arrears.

    This licence covers all required run-time licences for users of services or software delivered by the royalty licence holder. The licence requires a current Commercial Developer Licence and includes access to all Dyalog development environments, upgrades and support.

    Shrink-Wrapped/Single-User Run-Time Licences

    for off-the-shelf solutions

    A Shrink-Wrapped/Single-User Run-Time Licence is not hosted and shared by a set of users; instead, an installation package is distributed to a set of users and each user installs an individual Run Time Licence on their own desktop. This licence is well suited for the one-off distribution of simple applications that do not require upgrades or support.

    Shrink-Wrapped Single-User Run-Time Licences32-bit64-bit
    Bundle of 5 licences (one-off cost) £250 £375
    Bundle of 10 licences (one-off cost) £475 £715
    Bundle of 25 licences (one-off cost) £1,125 £1,690
    Bundle of 50 licences (one-off cost) £2,000 £3,000
    Bundle of 100 licences (one-off cost) £3,750 £5,625

    Dyalog File Server (DFS) Licences

    for the fast and secure sharing of data

    The Dyalog File Server (DFS) licence allows users to share data over networks through the Dyalog Component File system (DCF). The file server is a client-server system that manages the DCF system on behalf of all the users.

    Component files give users the flexibility to create a wide variety of data storage mechanisms and the DFS offers users a variety of advantages within security, performance, operations and recovery.

    NOTE: Each Dyalog File Server Licence includes a Commercial Run-Time Licence.
