awesome-selfhosted
A list of Free Software network services and web applications which can be hosted on your own servers
Project mention: Should I Run Plain Docker Compose in Production in 2026? | news.ycombinator.com | 2026-05-05Sure!
Get a few Beelink SER5 or SER9's, install Nextcloud to cover the files, document editing, communications (to save on Microsoft 365). Then you can have Gitea (and gitea actions) for your source code and building (skipping github enterprise), Harbor to host and scan your containers, frappe for HR, etc. Pretty much anything you pay enterprise rates for, you can self-host a version that will get your company from 1 to 100s with minimal extra work. If it's not on https://github.com/awesome-selfhosted/awesome-selfhosted, you can probably vibe code it in a couple hours.
I just started to run a k3s cluster with an almost enterprise grade software factory and a few (light) production workloads on a single cheap minipc.

n8n
n8n is a workflow automation platform for building AI-powered workflows and agents, connecting any AI model to any business system with full control over data, security, and deployment. Build visually or in code while n8n handles infrastructure from prototype to production with fully auditable executions.
Project mention: SOC-in-a-Box: One LLM, Eight Hats, A Production-Bar AI SOC on a Single GPU | dev.to | 2026-06-06n8n and similar visual workflow tools were on the list for one specific reason: leadership likes seeing the boxes-and-arrows. But the LLM nodes aren't first-class — you'd be wrapping every model call in HTTP, and the graph is in a database, not in code that's reviewable in a PR. Auditability and reproducibility are both worse than the LangGraph + bus path. (n8n is a great fit for non-LLM SOAR-style automations, just not for this.)

Project mention: Quick and easy local AI RAG setup with JetBrains IDE integration and browser UI | dev.to | 2026-06-02
To get a local web UI (that is very similar to CharGPT) that supports Retrieval Augmented Generation (RAG), workflows and many other features, we'll use Open WebUI (https://github.com/open-webui/open-webui). Although it can be setup using locally installed Python, I've decided to try out their Docker image instead. Since I have an Nvidia card, I've used their Nvidia GPU supported docker image.

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.
-
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.

Appwrite
Appwrite® - complete cloud infrastructure for your web, mobile and AI apps. Including Auth, Databases, Storage, Functions, Messaging, Hosting, Realtime and more
-
Gitea

Project mention: Gitea is 10 years old, but official repo is still hosted on GitHub | news.ycombinator.com | 2026-06-02 -

Project mention: GitLab Announces Workforce Reduction and End of Their Credit Values | news.ycombinator.com | 2026-05-11
What would you suggest as an alternative? Gitlab really sucks in my personal opinion, but what are your experiences with:
Gogs https://gogs.io/ (this IS gitea btw)
Forgejo https://forgejo.org/
Self hosted or cloud hosted. Also excluding Github because, please just fracking don't.

Jan is a desktop application — Windows, macOS, Linux — that lets you download, manage, and chat with open-source LLMs without touching a terminal. Think of it as a ChatGPT replacement where the server runs on your machine. Licensed under Apache 2.0, with the full source on GitHub, it sits in the same category as LM Studio and Ollama, with a distinctly different philosophy: Jan wants to be the complete local AI platform, not just a runner or a chat UI.
-
appsmith
Platform to build admin panels, internal tools, and dashboards. Integrates with 25+ databases and any API.

Project mention: I turned my Trilium docs into an AI-assisted site with one JS file | dev.to | 2026-05-04
I'd built an internal documentation site in Trilium Notes — about 30 notes covering product, marketing, and operations stuff. It was for non-technical teammates who needed to answer questions from developers about the platform.
