Blackfire support is on the way.
There is currently already an example how to add a Blackfire container to the Devilbox: https://devilbox.readthedocs.io/en/latest/custom-container/enable-blackfire.html
The glue that was actually missing are the PHP modules for Blackfire as well as the client/server/agent binaries on the PHP container.
This has now been addressed and is ready to be tested.
- [ ] Update documentation
I currently do not have a Blackfire license, so If someone who does is willing to make a proof of concept, I will add the steps to the Documentation.
