After comparing several options, I went with a dedicated server from #Hetzner. It's slightly above what I had in mind but much better suited for the load and future growth.

I need help with the server hosting all my open-source projects: #Fedilab, #HolosSocial, #HolosDiscover, and more. The current server costs €350/year but is no longer suited for the load. I often run out of disk space. I need to migrate to a more powerful one with expandable storage. Renewal is due in a few days. I have set a goal of €500 on Ko-fi, cost unknown.

#Holos started at the end of 2025. A full #ActivityPub server now runs on your phone, with the ability to use your own domain as your identity, #E2EE DMs via Signal Protocol, zero-knowledge encrypted backup, #ActivityPub media served from your own cloud, a tailored timeline based on your interests thanks to #HolosDiscover, and the ability to switch views depending on your mood or the content you want to browse. Thank you for your feedback and support that helped to go through these steps.

#HolosDiscover just hit 3 million indexed posts. What matters more than the number: 145k deletions processed, 83k edits tracked, and over 1k opt-outs respected, all in real time. Respecting people is the priority and the only way to do it right is to be a full #ActivityPub participant, receiving deletions, edits, and opt-outs as they happen. Before indexing anyone, Holos Discover follows their account, so they know they are being indexed and can opt out.
#HolosDiscover also has a script running in the background to detect instances that have blocked the actor or the domain. When an instance is identified, it is automatically blocked, which removes all indexed content from that instance. These instances are not displayed on the stats page.
#HolosDiscover now allows filtering results by multiple languages (for instance French + English). You can create timelines with up to 20 hashtags. You might be surprised to discover small accounts sharing hobbies you enjoy.
The #HolosSocial app already uses it. If you are an app developer, don't hesitate to use the API:
We will introduce the #HolosDiscover API in #Fedilab. It allows to tailor a timeline with up to 20 tags. It can be really useful for small instances. However, unlike the #Holos app where posts from blocked or muted accounts are filtered out, Fedilab won't be able to apply these filters.
In the next release of #Holos, Bloom filters will be enabled by default (can be disabled). This allows the relay to deliver only activities that matter to you, without ever knowing who you follow. In practice, this reduces data transfer around 97%, since only about 3% of activities are typically relevant during a sync. The public timeline is replaced by a discover timeline tailored to your interests.
