Kollaborate Server 2026.2.1 Beta 2 was released today as a pre-release version of our self-hosted workflow platform. This builds on Beta 1 which offered a new video player and image viewer.
You can now load a second file alongside another. You can compare any type of file with another, but if it's the same type it will automatically sync with the other player. Video and audio will sync playheads with each other and switching which file is active will switch audio source. Image viewers will sync zoom and pan position between each other, and document viewers will sync page numbers.
This behavior is customizable via the new Sync Settings panel. You can switch off sychronization and automatic audio and comment switching.
Comments switch automatically depending on which file is active, but you can also manually change this with a new dropdown in the Comments tab.
The document viewer for PDFs has been overhauled and now supports full screen and annotations.
There's a new viewer for text files that supports dynamic loading, meaning it can support very large files. It also supports full screen and there are options for line numbers and word wrap. You can comment on a specific line too.
The player page is no longer static, which means it loads faster and actions like setting workflows or switching between files can happen without a page refresh.
Because it's such a large change, we're releasing this update as a beta. Although it's been extensively tested, you should expect bugs in real-world usage.

Kollaborate Server 2026.2.1 Beta 1 - Apr 1 2026
Important: The Docker image is configured to convert the current database to your MariaDB version automatically. As such, we would recommend backing up the database before upgrading to any version as you may be unable to downgrade otherwise. You can download the current database as a .sql file from the Tools section of the Admin Area. We recommend doing this BEFORE copying the newer version's files over.
Note: This version contains major changes to our video player and image viewer. Although this has been tested extensively, we expect a change this big to still contain bugs in real-world usage and are releasing this version as a beta to get feedback.
Changes:
Kollaborate Server 2026.2.1 Beta 1 was released today as a pre-release version of our self-hosted workflow platform.
Our video player and image viewer have been completely rewritten from scratch. The new versions are considerably more powerful and easier to use. We’ve made lots of UI improvements and everything feels smoother, more polished and more intuitive.
There is now a button to skip forward 5 seconds, as well as new keyboard shortcuts comma and period for back and forward 5 secs, respectively.
The JKL keys function more like an NLE, with slow-mo support when holding K and J or L, as well as fast forward and rewind speeds up to 16x.
You can also change the playback speed separately without having to fast forward.
The new player allows switching between different file proxies, so you can now create multiple proxies and switch between them. It will also allow you to play back the original file (assuming it’s browser-playable) as long as you have download permissions for the file.
The new player is more resilient to playback or network issues. If something does go wrong, error messages are much clearer.
The new player has the ability to speak captions out loud. This allows you to bring in an audio description SRT and have Kollaborate speak it audibly as the video plays.
You can customize Kollaborate’s behavior when speaking captions, including automatically lowering the volume while the caption is spoken, or pausing playback completely. You can also set it to pause playback if the speech overruns the length of the caption and then resume again automatically.
The player functions better on smaller screens and touch-only devices.
Our new player supports overlaying 4:3 and 16:9 safe areas, as well as various aspect ratio mattes.
The biggest overhaul is to the annotation system.
Instead of a basic drawing pen that can’t be edited, we now have multiple tools including boxes, circles and arrows. After drawing, the shape can be moved about, enlarged, rotated or deleted. There is also a text tool that allows you to write directly on the image.
Shape colors are now independent from the comment’s color and different shapes can have different colors. There is also undo and redo functionality.
Because it's such a large change, we're releasing this update as a beta. Although it's been extensively tested, you should expect bugs in real-world usage. While we think the new player is a big step up in usability, we're interested in feedback on the new changes, especially for uncommon workflows.

We've introduced a new feature to the cloud version of Kollaborate: Organizations.
Organizations allow you to grant other users access to your subscription, replacing the old Linked Accounts feature.
To invite a user to join your organization, generate an invitation link and send it to them. Multiple users can use a single link. You can specify the permissions applied to any user with the link, but these can be changed later if needed. There are two permissions available: creating projects and accessing all projects.
We have migrated users of Linked Accounts to Organizations automatically. We tried to do a best guess of the organization name from the email domain, so we recommend visiting the Organization page and double-checking it's correct.
This is just the first step: Organizations allow us to unlock a lot of future functionality, including Single Sign-On (SSO), as well as improving the experience and customization for companies using our service.
Note: this feature is not relevant when self-hosting so it is a cloud-only feature.

Kollaborate Server 2026.1.1 is now out, with some significant changes to our self-hosted workflow platform.
We've overhauled how commenting works for shared links. The order of operations is now reversed: the user enters their comment first and is then asked for their name. This improves user-friendliness and solves situations where users couldn't figure out how to enter a comment or entered their comment in the name field by mistake. This is just for the first comment; they are not asked for subsequent comments.
This is not necessary when sending emails directly from Kollaborate, as Kollaborate will assign their name as the first part of their email address.
There is now a physical submit button for the comment box. This solves issues where some users could not work out how to submit a comment. You can still submit comments by pressing Enter.
We've made significant changes to how uploads and encoding jobs work behind-the-scenes, including rewriting most of our uploading code. Most of these changes are intended for the cloud and will not have noticeable effects when self-hosting, but you may notice slightly faster uploads.
This tool helps you locate files that exist on disk but aren't in the database. This can occur if the file was scheduled for deletion but permissions issues prevented it from being deleted.
We've increased the contrast of some user interface controls to be more accessible, as well as improving how the site appears on screen readers. We plan more improvements in this area in future updates.

We’re launching a new feature on this blog where we update you on the progress of Kollaborate every quarter. Because this is the first, we’re going to outline the past year and what we’re planning over the next quarter.
Over the past year we released our new Rust backend, which has allowed us to speed up and modernize many features of the site. We have gradually moved more and more features to the new backend, including file operations, viewing comments, file delivery, thumbnails, and some parts of the upload process. User-facing pages are still using the old backend but will speed up as more features are moved to the new backend.
The new backend also gives us a lot more insight into how well the service is operating, so we can respond more quickly to problems, especially problems that are region-specific and don’t affect the US where we are based.
We also added many new features including emoji comment reactions, instant file moves between projects, file tags, tagging a user in a comment, global search, template projects, saved searches, and more.
What we’ve been working on for the past five months or so is switching to a different storage provider. Unfortunately it wasn’t as simple as just swapping over a URL and required us to account for a lot of different factors than we had to with our previous provider, so this has been a long, arduous process. But we’re almost at a place where we can switch over completely, so that will happen very soon.
Part of this process involved making significant changes to how we handle uploads. We rewrote our uploader to better handle every kind of possible network condition, as well as significantly speeding up the Finishing stage. This is most noticeable on larger files, where finishing will now take 1-2 secs irrespective of file size, where before it could take minutes for a very large file. We now have lots of stats about the upload experience to help us monitor and improve it, and our new system is able to detect problems automatically and route around them.
Over the next quarter we plan to finish the storage changeover and begin to reap the benefits of switching storage providers, including faster video encoding and improved video quality. We also have other features in the pipeline, such as new workflows, better accessibility, a new help center, a new video player, and a captioning overhaul, but not all of these will launch this quarter.
