Xdebug Update: January 2021

Another monthly update where I explain what happened with Xdebug development in this past month. These will be published on the first Tuesday after the 5th of each month.

Patreon and GitHub supporters will get it earlier, around the first of each month.

You can become a patron or support me through GitHub Sponsors. I am currently 94% towards my $1,000 per month goal.

If you are leading a team or company, then it is also possible to support Xdebug through a subscription.

In January, I worked on Xdebug for about 60 hours, with funding being around 35 hours. I worked mostly on the following things:


The start of the month saw the release of Xdebug 3.0.2 which addresses further issues that are present in Xdebug 3.0. Xdebug 3.0.2 mainly addresses issues related to triggering features in Xdebug through Xdebug's new modes, and a few issues related to code coverage were fixed too. Expect another bug fix release in February, as I am intending to make one release per month.

Now that the GitHub repository of the VS Code Plugin has been moved to the Xdebug organisation, there is going to be progress here too.

DBGp Client and DBGp Proxy

I have had some expert reviews of the Go code for DBGp Client and DBGp Proxy, by JetBrains developers working on their GoLand IDE. Once I have reviewed and integrated their comments I am intending to release the source code of these two tools under an open source license.


I spent some time adding anchors throughout the documentation to make it easier to link to specific sections. The upgrade guide now also has a Japanese translation.'s code has been updated to allow for translations of the documentation, although I do not have any plans to translate the rest of it at the moment. The main issue with having translations of the documentation that the translations also need updating when the original in English changes.

As part of Xdebug's documentation efforts I created another video in my series on Xdebug 3. This new video explains Xdebug 3's diagnostics features to help finding issues with Xdebug's configuration and settings.

The next video that I am going to release will deal with how to trigger Xdebug's features, such as single step debugging, profiling, and tracing.

Xdebug Cloud

The Xdebug Cloud now has a design, created by Simon Collison. With the design in place, I am currently putting the dots on the i's related to signing up and billing. I expect to launch Xdebug Cloud for beta customers during this month.

If you want to be kept up to date with Xdebug Cloud, please sign up to the mailinglist, which I will use to send out an update not more than once a month.

Business Supporter Scheme and Funding

In January, no new supporters signed up.

If you, or your company, would also like to support Xdebug, head over to the support page!

Besides business support, I also maintain a Patreon page and a profile on GitHub sponsors.
