awesome-selfhosted
A list of Free Software network services and web applications which can be hosted on your own servers
The awesome-selfhosted list is maintained on GitHub. Links on the GitHub version are sanitised like other user-generated links. But the rendered version on awesome-selfhosted.net is generated as the maintainers' own HTML, so those links do not inherit GitHub's attributes.

Project mention: Demystifying Cloud in a Bottle: A New Approach to the Self-Hosted Stack | dev.to | 2026-09-18
The ambition behind Cloud in a Bottle is to solve the 'last mile' problem of self-hosting. By abstracting the complexity of container management, the project allows developers to focus on the applications themselves rather than the underlying plumbing. While the networking component is currently in flux, the modular design allows for integration with existing professional-grade tools. By understanding the core request path, from TLS termination via Caddy to the final container delivery, you gain the skills needed to troubleshoot effectively when things go wrong in a production or home environment. Embracing this level of technical transparency is how the open-source community will continue to push the boundaries of what is possible in personal computing.

searxng
SearXNG is a free internet metasearch engine which aggregates results from various search services and databases. Users are neither tracked nor profiled.
Project mention: Nitter has more working instances than before the takedowns | news.ycombinator.com | 2026-09-05The solution is to run your own instance, create a few accounts for it to use and put it behind a reverse proxy with basic auth. Hang out logins to a few people and it will remain useable. Of you put your instance out in the open it will sooner or later end up temporarily blocked - I tried this for a few years, same results every time - but smaller instances remain useable.
It isn't hard to run an instance, just park it next to your SearXNG [1], Invidious [2], Redlib [3],PeerTube, ... instances.

hosts
🔒 Consolidating and extending hosts files from several well-curated sources. Optionally pick extensions for porn, social media, and other categories.
I'm currently (very slowly, in the small gaps between 'life') setting up a site the host the lists and also explain them.
Since it's not ready, it'll be best if I point you to the sources I've aggregated from:
https://firebog.net/
https://github.com/hagezi/dns-blocklists
https://github.com/StevenBlack/hosts
https://github.com/jerryn70/GoodbyeAds
Link to my in-progress list file hosting: https://lists.uninvitedactivity.com/DNS/
00_Tiers directory:
I've aggregated the lists into four tiers: Base, Recommended, Aggressive, and Paranoid. And I've got two sets of these, one that includes Newly Registered Domains (Full directory), and one that doesn't include NRDs (NoNRD directory, because NRDs are ... heavy: Paranoid list with NRDs: 9.1 million records, without NRDs: 3.7 million records).
11_Allow directory:
A bunch of allow lists sourced from: https://discourse.pi-hole.net/t/commonly-whitelisted-domains.... I also use this list for an Allow list: https://github.com/anudeepND/whitelist
21_SpecificTopics directory:
Aggregation of lists under the topic that matches the file name. Fake News list needs to be updated as it contains a _way_ overbroad list that I need to remove from the aggregation.

Project mention: Google Maps results to emails: add contacts to a Maps Scraper dataset, one row per place | dev.to | 2026-10-11{ "place": { "title": "TEST FIXTURE place A: plausible.io (first place on this domain)", "placeId": "hiver-fixture-place-a", "address": "1 Fixture Street, Testville, TS 00001", "phone": "+1 555-0101" }, "website": "https://plausible.io", "status": "ok", "emails": [ {"email": "hello@plausible.io", "type": "general", "sourceUrl": "https://plausible.io/contact"} ], "socials": { "x": "https://x.com/PlausibleHQ", "linkedin": "https://www.linkedin.com/company/plausible-analytics" }, "address": "Västriku tn 2, 50403 Tartu", "addressSourceUrl": "https://plausible.io/imprint" }

keepassxc
KeePassXC is a cross-platform community-driven port of the Windows application “KeePass Password Safe”.
For now: https://github.com/keepassxreboot/keepassxc/issues/10406
Or not: https://github.com/Kunzisoft/KeePassDX/issues/2321
They are imo clearly gearing up to lock down passkeys in practice one day so that you will only be able to use those tied to a Google or Apple account (or some new player). They're already threatening in these issues to blacklist open implementations that don't submit to their requirements, and then requiring an attested client would then become the "best practice" adopted blindly and widely. I think the only hope is for the open clients to fully submit, hoping to avoid full attestation, while not making it too hard to patch out the anti-features.
