📣 Join us for @redsolver.dev's talk on @skyfeed.app's evolution to an open-source platform with custom Rust indexing for AT Protocol. Learn how it could enable a fully independent, EU-hosted AppView - solving a key Bluesky decentralization challenge! ahoy.eu/speakers/red...

Hey SkyFeed users, fly.io is currently having a "Major Outage" in the IAD region where the skyfeed cache infrastructure is hosted: status.flyio.net As a result, all skyfeed feeds are currently down until fly.io is back online, very sorry about that.

I'm sorry for the current SkyFeed outage, I'm pretty sure it's caused by @fly.io which I use for smart caching of feeds. It usually works great. See https://status.flyio.net/ for status

All SkyFeed feeds should now be back online, thanks for your patience! This has been the first and only downtime in the last 4 months.

Time for some cool feeds on bsky! @redsolver.dev has built these feeds for you based on skygraph.art community detection data A lot of people might find these useful as-is, but these feeds are just the first baby steps - building blocks, that can go into a more complicated Home/Discovery feed. 🧵👇

Hey SkyFeed users, Hetzner is experiencing a vSwitch outage which affects the SkyFeed query engine servers hosted in Finland. I'm re-routing requests to Germany now so feeds should still work, but they might be a bit slower to update than usual! status.hetzner.com/incident/1db...

I would like to thank everyone who already donated via GitHub Sponsors (https://github.com/sponsors/redsolver) 💙 Thanks to *you*, SkyFeed is now over 52% of the way to being sustainable, meaning SkyFeed can continue to host free feeds for millions of users, without any ads or similar bullshit!

We just reached 40 000 custom feeds on Bluesky! 🎉 If you're interested in self-hosting a SkyFeed-compatible feed engine (it's open-source), send me a message and we'll get it set up! It would be great to diversify the ecosystem :) These are the 16 most-used feed generators currently on the network:

90% of SkyFeed feed requests are now served in 24 milliseconds or less, with only about 1% of requests taking 4 seconds or more. And after adding protection against recursive "feed bombs" today (feeds using themselves as an input), over 99.9% of requests now return with a HTTP 200 OK status code!

My shiny new database server ran out of file descriptors because I only set higher limits for users when setting it up, but the DB runs as a systemd service (which has different limits). As a result, some SkyFeed feeds were stuck on old state for up to 6 hours. Sorry about that, should be fixed now!

You may have noticed that SkyFeed is a bit unreliable at times. This is caused by a small number of feeds being extremely slow and blocking the data structures. I'm trying to fix this with some Rust magic, but please also verify that your feeds take less than 10 seconds to generate in the Builder!

I just found and fixed a bug which caused all feeds using "single user" inputs or any type of "list" (input, remove) blocks to fail. If your feed was broken for the last few hours, please check again - there's a good chance it's fixed now!

All SkyFeed feeds are now back online, thanks for your patience! The feed generator backend is now serving 120 feed requests/second :O New posts might still be a bit delayed, please reply to this post if your feed is having other issues.

The SkyFeed infrastructure is a bit overloaded, I am currently working on setting up a new query engine server and redirecting some of the traffic there. So everything should be back to normal in about 1 to 2 hours, thanks for your patience!

✨ SkyFeed v0.9.9 ✨ • Improved Search • Feed Builder Preview: Highlight images with ALT text matching RegEx • Android: Account Switcher works now • Android: Set target language, ignore languages or disable automatic translation • Other UI improvements Download APK: github.com/skyfeed-dev/...

🛠️ SkyFeed Builder Update (v0.9.7) [2/2] 🛠️ • New "Replace" block to replace all posts in a feed with their parent post, root post or quoted post (useful for feeds which want to show posts based on specific text in replies for example, like a specific emoji) Try it on https://skyfeed.app

🛠️ SkyFeed Builder Update (v0.9.7) [1/2] 🛠️ • New experimental "Remember Posts" block to keep almost unlimited post history beyond 7 days (great for feeds with less frequent new posts) Try it on https://skyfeed.app The Android APK will be updated soon!

Hey feed builders, Bluesky started rejecting non-UTC-timestamps for new records today (good change!) and SkyFeed had a bug where it did not convert the timestamp when publishing feeds. This is fixed now, so it should be possible again to publish and update feeds!

Due to a small bug in the indexer, lists created using the List Architect (see embed) could not be used as inputs/removes in the SkyFeed Builder. This is now fixed, but you might need to re-create the lists for them to work.

✨ The 𝙇𝙞𝙨𝙩 𝘼𝙧𝙘𝙝𝙞𝙩𝙚𝙘𝙩 is now live on skyfeed.app ✨ You can use it to create lists based on RegEx matching display names, handles and the full profile description. This feature is still highly experimental, so please be careful and report any issues and bugs you might encounter here in this thread!

SkyFeed v0.9.3 just went up, including the new Mute RegEx feature!

Introducing the Mute RegEx, available in the SkyFeed App later today! Use it to easily mute posts which contain specific words, phrases or phone numbers across the entire SkyFeed App.

📱SkyFeed is now available for Android📱 Download the APK here: github.com/skyfeed-dev/... This is the first mobile release, so please be aware that it might not be completely bug-free yet! Some of the more interesting features are automatic (offline) translations and real-time interaction counts.

Feed of Feeds updated, it now sorts posts by likes and freshness (HN algorithm). Use it to discover new interesting feeds!

Feed of Feeds updated, it now sorts posts by likes and freshness (HN algorithm). Use it to discover new interesting feeds!

You can now view the source code of any published builder feed on Bluesky, directly in the SkyFeed app. Most feeds (if licensed correctly) also show a new "Fork" button which you can use to save a copy of the feed in your personal builder, modify it and even publish new and improved versions!

✨ New personalized Feed: Liked by Follows ✨ It contains posts liked in the last 10 hours by users you follow. However, the more posts someone has liked, the less their likes are worth. So the feed might highlight interesting posts by users who don't use Bluesky that much yet :)

New app feature, you can now explore any feed you want using the new Gallery View! Try it on skyfeed.app

🛠️ Builder Update (1/2) 🛠️ • New "Embed" target for the "Remove" block (for example remove all quote posts or only keep posts which link to a custom feed) • The RegEx text field is now up to 24x bigger! (only if needed) • "Single User" input blocks now optionally include like, reply and repost counts

Hey SkyFeed users, please make sure your app is on version v0.8.3 or later (written in the top left). This release fixes a security vulnerability which could lead to someone stealing your session if they tricked you into clicking a maliciously crafted link. Not exploited in the wild yet afaik!

New Gallery View, coming soon to the SkyFeed app! Works with all columns (feeds, timeline, profiles, ...)

✨ New personalized Feed: Liked by Follows ✨ It contains posts liked in the last 10 hours by users you follow. However, the more posts someone has liked, the less their likes are worth. So the feed might highlight interesting posts by users who don't use Bluesky that much yet :)

The Discover feed is back online! Still a bit experimental, so please let me know if it doesn't load for you. Also, the OnlyPosts and Mutuals feeds have been moved to new infrastructure and now use the same query engine as the more than 15 000 custom feeds published using the SkyFeed Builder!

The SkyFeed Stats page is back online! It lists the most popular feeds powered by SkyFeed and how often they were loaded, scrolled and refreshed in the last 72 hours. stats.skyfeed.me

SkyFeed just got a new logo! Designed by J&S Business Products in partnership with @brushfeather.bsky.social + I'm working on a new version of the SkyFeed app with a bunch of new features (including all the most requested ones), which will also be available for native Android in addition to Web 🐦

New SkyFeed feature, coming soon!

All SkyFeed feeds except Discover should be back online now! Unfortunately that specific feed is extremely resource-hungry on the new infrastructure, so it needs some major optimizations before I can turn it on again. Thanks for your patience 💙

So repo v3 broke some skyfeed infrastructure, I fixed the newest DB instance so all of the custom feeds you made using the builder should be back online+working. other feeds like Mutuals will be stuck until tomorrow because it's harder to fix them (old infra) and I really need to sleep now (UTC+2)

The SkyFeed Builder shows how long your blocks take to execute. Query times up to 500ms are great, even 2 seconds are still ok. But if your massive RegEx takes 30+ seconds, please don't publish it! This only applies to a very small number of feeds, but it degrades the performance for all users :(

🎉 We just reached 10,000 custom feeds on Bluesky! They are one of the most unique features of this network and a key driving force for discovery and communities. 87% of all feeds were created using the SkyFeed Builder, which also means that their internal algorithm is public and transparent.

Some feed builders seem to be using 100+ individual inverted RegEx blocks in their feeds which is causing massive performance issues. It's possible to do exactly the same thing with only ONE normal and ONE inverted RegEx block with pipe | symbols. Please optimize your feeds, ping me if you need help

✨ Our first featured community project — @skyfeed.app, created by @redsolver.dev! SkyFeed allows users to create a dashboard out of their feeds, profiles, and more, and the integrated SkyFeed Builder easily builds custom feeds off of regexes or lists. Read more about the project here:

Hey feed builders, I just updated the query engine. Should be more stable, new posts appear faster and max. post history for single user inputs! I tested the top 100 feeds, but the architecture changes could cause your feed to stop working. If that's the case, reply to this post so I can debug it!

The SkyFeed feed generator is now hosted on fly.io with Dragonfly DB and running great! It's responsible for pagination (scrolling down a feed) and caching feeds to reduce load on the query engine itself. The engine will be updated tomorrow with unlimited post history for single user inputs!

The skyfeed builder feeds were down twice in the last 24h (~ 15 mins). This was caused by an out-of-memory kill of the query engine. I'm setting up a new 128 GB RAM root server and optimizing the structure of the DB to prevent this in the future!

SkyFeed Stats website updated with more details and a new design: https://stats.skyfeed.me loaded: how often the feed is loaded/viewed scrolled: how often users actually scroll past the first page refreshed: some clients automatically refresh the feed every X seconds to check for new posts
