We added RSS feed support to #HolosDiscover for Trending and Timeline. For the timeline, you can create feeds by filtering with hashtags (up to 20). There is a URL feed generator to make things easier. More at https://discover.holos.social/feeds
We heard you. #HolosDiscover has been shut down, all indexed data deleted, and the source code removed. We apologize for the misunderstanding. Our approach was built with the deepest respect for user consent, but we understand it could rightfully be seen as misusing the indexable flag that many users didn't consciously enable. This highlighted a real conversation the Fediverse needs about default settings. Thank you for the feedback.
Brief maintenance for #HolosDiscover, the search service will be offline for about 30 minutes for a server migration.
#HolosDiscover 1.3.0 has been released!
New search filters: min_likes and min_boosts to filter results by engagement. Trending sections now load independently for faster rendering.
Search rate limit increased from 5 to 30 requests per minute.
Bluesky bridges are now detected and blocked. AT Protocol lacks indexable flags, so bridged users cannot consent to being indexed.
Spam farming instances are now blocked via IFTAS denylist import.
Some of you noticed that @HolosDiscover is following you. It's a Fediverse search engine we built to solve a problem: when you start your own server with #Holos, your index is empty. #HolosDiscover provides a ready-to-use content catalog for everyone.
Only public posts from consenting users are indexed. Deletions and edits are reflected in real-time through ActivityPub activities.

Open-source (AGPL-3.0): https://codeberg.org/tom79/Holos-Discover
After shutting down #HolosDiscover, we're rethinking the approach with #HolosIndex: users explicitly opt in by adding #HolosIndex to their bio with interest tags, then submit their profile. No assumptions, no default settings.
This will power interest-based discovery across the #Fediverse, helping people find each other through shared interests. Still all through #ActivityPub of course, with real-time deletions and updates.
With #HolosDiscover we checked multiple criteria before indexing: "indexable" enabled, account not locked, no #nobot or #noindex in bio, not in opted-out list, only public posts. Every deletion, edit or block was processed instantly via #ActivityPub.
Google uses that same "indexable" flag but ignores everything else, keeps deleted content cached for weeks.
We shut it down after pushback. Was that the right call? Don't hesitate to share, this concerns the whole Fediverse.

The results are in: the community wants #HolosDiscover back. So we'll be bringing it back.
Source code will be reopened and the service restored from a clean slate as all data was deleted when we shut it down.
We've also heard the concerns and will work on making the opt-out process even more visible.
#HolosDiscover is back, from a clean slate.
A #Fediverse search engine that uses standard #ActivityPub federation. It follows you like any account, respects indexable flags, #nobot, #noindex, locked accounts. Deletions, edits, blocks are processed instantly through ActivityPub.
You have full control. Block it, mention it with "unfollow", or disable indexing in your settings.

#HolosDiscover was built to solve a concrete problem: when you join #HolosSocial, your mobile server is empty. No posts, no accounts to find. The API provides search and trending content as a fallback for servers with no indexation yet.
We built a web UI at https://discover.holos.social using the same data, so anyone can see what's indexed without being a developer. Any Fediverse app or instance can also access it through the API.
#Holos 1.0.0-rc-3 has been published. This release now integrates #HolosDiscover for searches and to display trending. You can also block domains and sync remote blocking lists of domains. You can also import your list of blocked accounts. Account deletion is now possible through the app.

Today we made some changes to #HolosDiscover. Trending posts are now evaluated over 24h to give more visibility to fresh content. We'll also be working on trending links.
Everything is available through an API. The web version makes it accessible to anyone without technical knowledge.
Website: https://discover.holos.social/
About the project : https://discover.holos.social/how-it-works
Next #Holos release will use Bloom filters (https://en.wikipedia.org/wiki/Bloom_filter) for sync. The relay filters activities, only sending those from accounts you follow and from the local timeline.
The filter is sent each sync and never stored. The relay still has no knowledge of your followings.
Test: 26 followings, 32k pending activities filtered down to a hundred (99.7% reduction).
The public timeline goes away as a result. #HolosDiscover will replace it with content tailored to your interests.
#HolosDiscover 1.1.0 has been released.
The trending algorithm now uses time decay so recent content gets more weight. Older posts don't dominate the results anymore.
A privacy page has been added: https://discover.holos.social/privacy
There's also an API documentation page with interactive testing: https://discover.holos.social/api-docs
API keys are only needed for server-side apps (same IP for all requests). Mobile and desktop apps don't need one, rate limits are per user IP.
We published #HolosDiscover 1.2.5, this release fixes RSS issues on some readers:
https://discover.holos.social/feeds
Also, for more transparency, we added a real-time stats page showing processed #ActivityPub activities, blocked instances and more.
RE: https://mastodon.social/@HolosSocial/116166995091607292
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.
#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:
#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.
What's Holosdiscover? https://discover.holos.social/how-it-works
#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.
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.

Sharing this post helps keep my open-source projects alive.
#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.

Ten days ago, I asked for help with the server hosting #Fedilab, #HolosSocial, #HolosDiscover and more.
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.
Specs for the curious: https://www.hetzner.com/dedicated-rootserver/ex44/
Migration is underway.
Thanks to everyone who donated or shared. It means a lot 🙏
