Project mention: Uptime Kuma vs Hosted Monitoring: Self-Hosted Is Not Always Free | dev.to | 2026-04-21
Uptime Kuma is one of the most popular open-source monitoring tools available today. It is self-hosted, beautifully designed, and completely free to use. If you are looking for an Uptime Kuma alternative or evaluating self-hosted monitoring against hosted options, you have probably seen it recommended in every Reddit thread, Hacker News discussion, and developer forum on the topic.

> Like… has anyone done a Jepsen-like stress test on rsyslogd and shared the results? I’ve half-assedly looked before and not been able to find anything.
I've not used rsyslogd specifically, but I don't see how you'd have any issues with the log volume you described.

Moby
The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
There were many attempts to fix this issue by changing cgroup isolation settings using flags like --cgroupns=host etc ,but nothing worked. Similar outcomes were also obtained by other attempts like these. https://github.com/moby/moby/issues/16238

Project mention: EKS vs k3s on AWS for startups: cost, complexity, and when to choose each | dev.to | 2026-04-26
k3s: You run the control plane on an EC2 instance. It starts in under a minute, ships with Traefik and a working storage class, and upgrades when you decide. Nothing AWS-specific unless you want it.

Project mention: Get your passwords out of Bitwarden while you still can | news.ycombinator.com | 2026-05-21
If you're going to the trouble of self-hosting, I'd suggest just running vaultwarden.
https://github.com/dani-garcia/vaultwarden
It's entirely compatible with the clients. It also removes a lot of "rug-pull" potential, and gives you the ability to access all the nice features (ex - multi-org, multi-user, shared vaults, totp, etc...)
Honestly - part of the reason I like Bitwarden is that if they ever go full "enshittification", it's going to be relatively easy and straight-forward to just move entirely off their projects and onto open-source forks.

memos
Open-source, self-hosted note-taking tool built for quick capture. Markdown-native, lightweight, and fully yours.
ObjeX currently serves as the S3 backend for our Outline and Memos instances. Both use presigned URLs and server-side uploads through the standard AWS SDKs, no special configuration needed.

coolify
An open-source, self-hostable PaaS alternative to Vercel, Heroku & Netlify that lets you easily deploy static sites, databases, full-stack applications and 280+ one-click services on your own servers.
Install Coolify (free, open source) on a VPS and deploy Memos from its catalog. You get a web UI and auto-updates, but Coolify itself wants ~2 GB of RAM, which is heavier than the app it is managing. Worth it only if you are already running Coolify for other apps.

Docker-OSX
Run macOS VM in a Docker! Run near native OSX-KVM in Docker! X11 Forwarding! CI/CD for OS X Security Research! Docker mac Containers.
-
it reminds me of https://github.com/dockur/windows with its compose-style YAML over QEMU/KVM. The difference i'm seeing is scope: dockur ships curated OS images (Windows/macOS), while holos looks more like a generic single-host VM runner. Is that a fair read? also curious any plans to support running unattended processes for OS installs?

plane
🔥🔥🔥 Open-source Jira, Linear, Monday, and ClickUp alternative. Plane is a modern project management platform to manage tasks, sprints, docs, and triage.
Project mention: 5 Open Source Alternatives Worth Considering Before Renewing Expensive SaaS Tools | dev.to | 2026-04-10Jira renewals are one of the most expensive recurring line items for engineering teams, and the justification for the price tag has gotten weaker as the product has accumulated features most teams never use. Plane is an open source project management platform that covers issues, sprints, cycles, and roadmaps with a clean interface that feels built in the last few years rather than the last two decades. The source is on GitHub and the self-hosted install runs on any Docker host.

Forgejo https://forgejo.org/
Self hosted or cloud hosted. Also excluding Github because, please just fracking don't.
