Does Collabora CODE 26.04.2.4 Have Any User or Concurrent Connection Limits

Hi Collabora Team,

I have a question regarding the user/concurrent connection limitations in the free Collabora Online Development Edition (CODE).

We are currently integrating Collabora Online into our application and running Collabora CODE in an Azure Container. We are using Collabora Online version 26.04.2.4.

Our application supports editing documents such as Word (DOCX), Excel (XLSX), PowerPoint (PPTX), ODT/ODS/ODP, and other supported formats through Collabora.

I found an older official Collabora release announcement from 2019 (CODE 4.2.0) that mentioned:

“CODE warns users that they might want support after 10 concurrent documents or 20 concurrent users.”

Reference:

I also found a later discussion on the Collabora forum where it was stated that:

“There are no limitations of documents / connections in CODE anymore.”

Reference:

I would like to clarify the current behavior for the latest CODE version.

If we use the free CODE version in our Azure Container and our application grows to 30, 50, 100, or even 1,000 users, is there any hard limitation on the number of users or concurrent connections/documents?

For example, if 1,000 users are using our application and many of them are simultaneously opening/editing documents through Collabora, will the free CODE version:

  1. Restrict the number of concurrent users or connections?

  2. Restrict the number of concurrently opened documents?

  3. Stop allowing additional users after reaching a specific limit?

  4. Have any other licensing or technical limitation related specifically to the number of users?

I understand that server CPU, RAM, and overall infrastructure capacity can affect performance. My question is specifically whether the free CODE version itself has any fixed user/concurrent connection/document restriction, similar to the old 10-document / 20-user restriction mentioned in the 2019 release.

Could you please confirm whether this restriction still applies to CODE 26.04.2.4, and if there are any current limits for a large number of concurrent users?

Also, does Home Mode have any different user or connection limitations that we should be aware of when running CODE in an Azure Container?

Thank you for clarifying this.

There are no limitations of documents / connections in CODE anymore.

This is still true, as far as I know. You get a welcome screen and a user feedback popup, but there is no doc / connection limit.

You can also enable home mode, it means:

Home users can enable this setting, which in turn disables welcome screen and user feedback popups, but also limits concurrent open connections to 20 and concurrent open documents to 10. The default means that number of concurrent open connections and concurrent open documents are unlimited, but welcome screen and user feedback cannot be switched off.

If you want no welcome screen, no feedback dialog and no limits, then please use COOL. Thanks.

Thank you for the clarification. Just to confirm, can we use the default CODE mode for our commercial production application without any licensing restrictions as our user base grows?

Hi @sabarirajpazhani,

Before going further, could you share a bit more about the type of production application you’re building and how you plan to use CODE? If this is for a commercial production deployment, you’re also very welcome to discuss your specific requirements directly with our Sales team sales@collaboraoffice.com , who can advise you on the appropriate commercial offering and SLA options.

Regarding the technical part of your question, we can confirm that CODE itself does not have a document or connection limit in the default mode, as Miklos mentioned above. The 20 concurrent connections / 10 concurrent documents limits apply when Home Mode is enabled.

For the licensing/commercial-use question, though, we would not want to provide legal or licensing advice on the forum. Our Sales team sales@collaboraoffice.com can discuss your particular production use case, licensing requirements, and available options with you.

If you’d like a maintained, white-labelled version of COOL for commercial use, that is also something Collabora provides as a commercial service.

Thanks!

Hi @darshan

Thank you for confirming the details about Default Mode and Home Mode. That is very helpful!

Currently, we are in the initial pilot and testing phase for around 100 to 200 users who will be editing standard Word (.docx) and Excel (.xlsx) documents. We want to test the technical performance in our Azure Container first before exploring commercial options.

From your technical experience with CODE:

  1. What CPU (vCPU) and Memory (RAM) size do you recommend allocating in our Azure Container to smoothly support this 100 to 200 user load?
  2. Are there any recommended container tuning tips or settings to get the best performance?

Thank you for your help!

Thank you @markus for sharing the hardware provisioning guide. It provides the required CPU, RAM, and sizing guidelines for our 100–200 concurrent user pilot. If I need any further information, I will let you know.
