Unless I am blind or my search-fu is hugely failing me, I cannot for the life of me find any information on the recommended/minimum specs to self-host the matrix backend services. I’m trying to spin up a VM just to play around with it and see if I like it. Specifically, I’m looking at Synapse or Continuwuity. Any advice?
Looking for vCPUs, memory, storage.


I have ran Synapse natively on 1 CPU 1GB RAM VPS for years. But it fills up a lot of disk space, eapecially with larger rooms, so get at least 100GB? (I had 20GB on my VPS, and with 4 regular users, was using up 15GB)
If you are looking at (new) official ESS Community, they recommend 2 CPU, 2GB RAM minimum for Kubernetes.
You can set it to use object storage instead, much cheaper
Could you expound on what you mean, or how to go about it? Links to documentation would be appreciated.
I’m not sure your level of understanding of cloud infrastructure, so let me know if you need me to go into more detail. Disk storage, like what is attached to a VPS/VM is very expensive, and it’s the 100GB drive you have attached. What is much cheaper is object/blob storage, known in AWS and most cloud providers as S3. This is far far cheaper for many reasons.
Matrix (and really I should say Synapse, what I use) can be configured to save images, photos, uploads, etc to save to a blob storage “bucket” instead of disk. So you can lower your disk from 100 down to something lower because your data is stored in blob storage (fully encrypted). For synapse, the module you need is here: https://github.com/matrix-org/synapse-s3-storage-provider
