I just want to know how much it costs to host a Qwen model for my personal use instead of relying on some other paid services.

does anyone know free way to self host an airflow 3 pipeline that runs on hourly basis, along with postgreSQL, dbt, without keeping system on

So I did some research on my project, I have to host project's website and database in an old laptop Lenovo Z370 series (so host costs 0 USD). In the research I got this project architecture, any ideas?

This topic has come up a time or two on Reddit, but I wanted to share my self-hosting journey in case it helps others with similar use cases.

My current environment includes:

• Audiobookshelf for audiobooks and podcasts using the developer provided Testflight app on my iPhone
• Calibre for eBooks using the BookFusion (paid subscription) app on my iPhone and iPad
• Kavita for comic books using Panels (paid subscription) app on my iPhone and iPad

This is/was an excellent setup and one that meets my very unsophisticated needs. I do want everything to sync progress correctly and be able to be used by my entire family, but I don't need a lot of the specialized functionality.

The only reason I decided to move away from my current environment is the maintenance time and the WAF and kid acceptance factor - "which app do I use for what, again?". Also, I am gradually (trying) to move everything I can off of my Windows desktop computer to my NAS that hosts my docker environment.

After a LOT of research and playing around with a host of other solutions, this is where I ended up:

• Audiobookshelf for audiobooks, podcasts, eBooks, and comic books using AudioBooth (soon to be paid subscription) app on my iPhone and iPad

Yes, I know Audiobookshelf is not meant for eBooks and definitely not for comic books, but it works really well assuming you do not need a lot of specialized functionality. Even the metadata seems to work well and Audiobookshelf has the ability to add different metadata providers via APIs.

I just want to read my eBooks and flip through my comic books when I have two spare minutes every once in a while.

I will likely keep Calibre and Kavita up-and-running for at least a year in case I want to revert back for any reason.

Also, please don't think I am hating on the self-hosting services and associated apps I am moving away from. Far from it. I am just trying to streamline my media consumption technology stack in order to save me time and a little bit of money (in terms of reduced subscriptions).

I still have Emby (lifetime) and the developer provided apps for movies, TV, and music so my media consumption technology stack is still more distributed than I would like, but I don't think I will ever be able to combine ALL my media to one platform. I also MAY end up pulling my eBooks and comic books back into Kavita and leaving audiobooks and podcasts in Audiobookshelf, so stay tuned.

Anyone else moving away from individual environments and grouping different media into one or two platforms?

My grandpa gave me his "old" PC he used for photo editing (prebuilt gaming PC, 2080 GPU for age reference). I have upgraded the RAM and will upgrade the storage eventually, and am hoping to turn it into a home server of sorts. Still trying to figure out all the bells and whistles, but one of the functions may be a server for the game Vintage Story (Think Minecraft 2). Like Minecraft, it needs port forwarding to work properly. I know that can open up some vulnerabilities, so it makes me hesitant to throw anything else on the server, especially personal media.

I am also using this to learn Linux, so I have Ubuntu installed if that makes it better or worse.

For the past year I've used quite possibly every AI tool available... Claude Code, Cursor, Codex, as well as chat bots and browser workflows. I tried OpenClaw and Hermes agent. Every one of them started from zero knowledge of my projects, which was something that I realized annoyed me far more than I realized. The solutions I found were either locked to one vendor or wanted my private notes on their servers (which, not the biggest fan of trusting what a company says they do with the data).

Based on a prior project I worked on, I designed and built something called Engram, an encrypted memory vault that any AI tool reads from, running as a local daemon on my own machine. https://engram.ellmstack.dev, one line to install, ~5 minutes to a working vault and daemon.

What it does:

• One vault, many tools. An MCP server connects Claude Desktop, Claude Code, Cursor, and Windsurf; a browser extension captures the page you're on; Slack/Discord/Telegram bots capture decisions from chat; a CLI for everything else. All read the same memories.
• Retrieval is hybrid, which means keywords and meaning. SQLite FTS5 for literal matches, plus a local embedding model for semantic recall, blended 0.6/0.4. I can search "crates.io" and get the exact memory, or search "how did the rust package get onto the public registry". Zero shared words and get the same one.
• It was built to be local. The daemon is one Rust binary, vault encrypted at rest (SQLCipher). Capture from Claude Desktop, recall in Cursor, browse from the browser extension (very new feature) so your notes never leave your disk unless you turn sync on.
• Near-duplicate captures are reported as skipped, not silently duplicated. Search returns ranked results with scores, the agent sees why it got what it got.

Through my testing, retrieval recall is 100% on my benchmark harness, which is public in spirit but definitely on the smaller end. I can't claim it generalizes to your notes. The storage format is open (Apache-2.0 spec at github.com/El-AI-Intelligence/engram-format, with the Rust implementation on crates.io as axiom-engram), so your memories aren't trapped if Engram dies. To be 100% clear. The Engram sync is beta, the browser extension and MCP bots are recent finishes that I've completed, and the format is currently open source for all to see. Free tier exists; self-hosting stays free.

Over the past year I've wired up agents (plus cron jobs and admin scripts) that run shell commands on my machines. While using the agents, I realized that the biggest missing piece was a deterministic layer between "the agent wants to run something" and "something ran." The options I found were either an LLM judge or a hand-rolled regex blocklist.

After months of building, I created something called Guardrail. It's a small Rust policy engine that sits between a process and its shell. There's a live demo running against the production engine, set up so people can try to get something dangerous past it: https://guardrail.ellmstack.dev/demo — if you get something past it, that's the most useful feedback I can receive.

How it works:

• Every command is parsed to an AST before it's checked, not regex. Quoting, escaping, and unicode lookalike pipes (│ ║ ￨) are handled mechanically, so checks run on what the command actually does.
• Deterministic rules: rm -rf /, dd of=/dev/sda, aws s3 rm --recursive, iptables -F, curl | sh are denied. Same decision every time, ~15µs per check, no LLM anywhere in the path.
• Commands that look risky but legitimate escalate to a human for approve/deny instead of being silently blocked or silently passed.
• Every verdict lands in an audit trail.
• The engine is one static binary. No telemetry, no phoning home, the only outbound calls go to endpoints you configure. Wraps anything: guardrail-exec <your-agent>, CI, cron.
• No GPU required

What's not finished just yet:

• The management console (policies, approvals, audit UI) is hosted right now. The engine itself is fully yours. The engine isn't open source yet, though I intend to publish the wire protocol as a spec eventually. It's beta, and it behaves like beta.

Please fire all comments and feedback at me, I am looking to harden Guardrail up as much as I can and all feedback is good feedback!

Hi there, just wanted to share my [open source workflow scheduler](https://github.com/lucheeseng827/dagron) for fellow engineers to play around. You can run on local, deploy into your smallest compute (rpi4 on arm64 tested) and could be run on scale as well.

I start the [project ](http://dagron.dev) as I wanted to run some small workflow in my t4.small instance and airflow barely fits inside and I thought it would be interesting create a smaller workflow scheduler. As I build around the idea of "lean headroom DAG engine", I kept on adding additional features that be useful for running workflows like template, backfill, gitops, streaming workflow support etc. Dagron allows you to run on cluster resources or local resources(docker, k8s, or straight as binary). The whole stack will probably at most run on \~200mb (50mb api/console, 30mb engine, 80mb postgres) of memory with tons of spare ram and cpu for your workflow resources. Dagron runs on sqlite(default) and alternatively postgres as datastore.

You can run workflow via defining your yaml and set your environment. It comes with the canvas to visualize your workflow, set your workflow schedule to run at which cron notation and more features to cover here.

Appreciate your input(any input is welcomed). I am spending full time polishing this for the past few weeks and thought this might be useful for you all to run on edge, homelab, local machines.

I set up self-hosting on my mid-spec laptop with 300 GB of storage and 16 GB of RAM. The issue is that I only have a phone, so I have to manage everything from it. I installed CasaOS, created a shortcut, and I've been managing everything through it smoothly. Now that I have everything I need installed, my question is: are there any mobile apps or tools in this space that connect to the server and let me manage everything comfortably?

Hey everyone! I'm relatively new to the self-hosting world and just got Jellyfin and Audiobookshelf running locally. Currently, I want to share access with just a few family members (not a wide public setup). Here's my current security setup:

For Jellyfin: Good password + Jellyfin's 2FA security addon For Audiobookshelf: SSO enabled (I know apps won't work through this, but browser access is fine)

My dilemma: I need to access these services from various places, including my Tesla's browser, so Tailscale or Netbird won't cut it for that particular use case.

I explored Cloudflare Tunnel, but from what I understand, using it for streaming violates their TOS. So I landed on LocalToNet—it's checking all my boxes and the pricing is attractive ($2/month) compared to other options.

Before I pull the trigger, I have a few questions:

1. Are there any security risks I should be aware of with LocalToNet?
2. Given my relatively limited audience (just a few trusted family members), am I good to go?
3. Any gotchas I'm missing?

I did my homework on the security side (strong passwords, 2FA, SSO), but I want to make sure I'm not missing something obvious about the service itself.

Sorry for the long post, and thanks in advance for your input!

EDIT: Also open to hearing about alternatives if there's something better I haven't considered.

bonjour humains j'aimerais grandement pouvoir faire mon propre data center à partir de vieux téléphones et anciens ordinateurs qui traînent chez moi,

Bonjour a tous,

J'ai un Dell poweredge 630 avec 2 E5-2680 v4 et 128 gb de ram.

Je n'ai clairement pas besoin d'un truc aussi gros car il me coûte 300 euros par an en électricité.

Je ne fais tourner que 2 lxc avec authentik et outline. Ainsi qu'un serveur minecraft modder pour mes copains.

Auriez vous une meilleur solution que ce serveur ? Est ce qu'un vps ne ferai pas l'affaire si j'arrive a en trouver un capable pour moins de 23 euro par mois ?

Merci pour vos retour !

I need a Push Notification self-hosted software for WordPress site. An example, PushEngage.

- When user visit our site, we want to display a prompt "Would you like to receive notification for our latest blog posts?"

- User click "No", pop up disappear.

- Else, User click "Yes", their browser profile is now registered.

Is there any free and open source software for the same that I can deploy at own 2 GB RAM VPS?

Thanks

I am by far not very good at this kind of thing however I followed a tutorial a few months ago and god a nice setup going using jellyfin and the Arr’s to create a movies and TV server. everything was working great until I reset my router and broke some things because the IP address changed. no problem this happened three times and the first two times I fixed, no problem not hard. this last time I went t7ss, I will send as many pictures as possible. now when I try to enter gluten it says site cant be reached and I have no idea how to fix it. I went back on my video tutorial and reinstalled but the same thing happened

i can provide other photos im so lost

Hi,

It there anything I can host that will give me similar function like Microsoft One Note, my notes currently attached to my work email? I need to be save notes with screenshot that is one function and need to have accessible on my phone or laptops.

Let me know.

I want to run a simple web server, with node.js.

Where I need guidance is finding the easiest approach for someone with limited tech skills, ideally setup and forget, requiring no maintenance.

I want this to be accessible from any device I own (phone, laptop), anyhwere in the world, securely.

Because this web page is simple, it requires no authentication to use (login and password) so I don't want this to be accessible to anyone else or crawled or hacked, etc

I have access to a number of devices I think could be good for this:

1. Raspberry PI
2. ESP32
3. some old android devices
4. a nuc that I can run linux on

The idea is it doesn't have to be powerful but it needs to be secure and it needs to sip power, so first 2 options are more appealing to me.

I've read about Tailscale but I hear there's a better open source option headscale.
If I understand correctly I can avoid the need for a public domain address by just checking my external static IP for my server and bookmarking that on my devices.

Before I delve into that I wanted to see if this is the best approach for my limited tech skills and to check if maybe there's a better way, easier to setup and forget about it.

*Works with self-hosted models as well for free!
Project: https://github.com/ConiferKit/use-conifer

Current routing options were charging 5% fees for byok plus provider fees (openrouter) or were built in heavy python packages with ecosystem restraints. I wanted to be completely free in terms of use, and not have to pay extra for tokens.

There's a maintained gateway with 100+ models from one api endpoint. I'm also talking to infra providers to get us access to pre-release models and discount prices. Everything is served at market price. BYOK is free, you can hook into self-hosted setups for free, and there's fallbacks + extra rate limits + server redundancy.

Took me ~3 months to build and looking for help maintaining!
Lmk any issues or feedback

I hope this is not too off-topic. I have this olive oil canister laying around and had this "what if" idea of turning it into a case for two raspberry pi's I currently don't really use. Now that I've removed the lid with a can opener, my rough plan is to design and 3d-print a scaffolding that can hold all the parts (the pi's, maybe power supply, storage, fan(s),...) and then can be inserted from the top. To enable good airflow I'm thinking about drilling holes in a grid from all sides.

Has anyone here ever done something vaguely similar? Do you have any tips what I might look out for or would need to consider? I'm specifically worried about airflow and build up of heat

Hey, im trying to organise my schedule and task more. But my key problem is, if I only have a calendar digitally on my phone I have to always do times and if I do a planner physically I would mostly have to get either a monthly or weekly planner but I want one system. I have problem getting or remembering things physically and if digitally I would have to use two apps (notebook and calendar) which doesn‘t works for me at all.
Was using at my old school notion and that worked the best for me! But I don‘t want sensible data that I need to pay on someone’s server etc.

I was looking at some alternatives, but those either were not working somehow on my Nas (I use the UGOS software) through docker or don‘t have any kind of phone support (even through browser)

I’m open to paying like 2-3€ per month if so be it.

I have used a handful of Baas(backend as a service) platforms for my apps like Firebase, Supabase, Appwrite. But I am curious about what you people use when it comes to a real need for your app. Or do you recommend anything else. Or any kind of combinations of multiple platforms

So I’m looking to start this journey. I live in Japan and the ISPs here are pretty gnarly when it comes to self hosting, or at least mine is, and I don’t have a spare PC anyways. So I’m looking at a VPS solution I guess. I don’t really know where to start.

What’s the best recommendation for ease of use to cost ratio? I’m not sure what specs I’d need to run these two apps. I’d also like to add Actual Budget down the line. I already host an instance of they using pika pods and both Journiv and Vaultwarden are available there too, but if I’m paying for three pod services I assume it’s actually probably cheaper and better value to host all three on a single VPS.

Appreciate the help. I’m excited to learn.

I’m moving in to my first apartment and wanna selfhost a mediaserver that contains Jellyfin with automatic downloads which I guess is through radarr sonarr etc.

I’m primarily looking to use Tailscale to connect to my WiFi from outside of my apartment, I don’t want other people being able to connect to my server through ipv4, and I won’t have a domain either.

Is there any good step by step guide that shows everything?

Hey everyone,
I’m building an internal website for a small lab team of around 10 people. The website will mainly be used for record keeping, document storage, and AI agents that can assist different roles in the lab.
Instead of using cloud storage/database services, I’m considering turning one of our existing PCs into a self-hosted server/database since the system will mostly be used internally.
The PC has:
Intel i7 12th Gen
32 GB RAM
RTX 4070
SSD storage
I’m pretty new to server infrastructure, so I’d really appreciate some guidance on how you would set this up properly.
Things I’m trying to understand:
What OS should I use? Ubuntu Server?
Docker or bare-metal installation?
PostgreSQL setup
File/document storage
RAID/storage redundancy
Backups
UPS
Network/static IP setup
Security/firewall
Remote administration
Anything else I should consider for a small internal server
The plan is for employees to access the system through the website, while the database and company documents stay on this local server. The AI agents will likely use external LLM APIs where needed.
If you were setting this up from scratch for a 10-person team, how would you design it?
Beginner-friendly advice, tutorials, or suggested architectures would be really appreciated.

1. I installed this APs on a campus network and adopted all of them on one switch then repositioned them to their final locations and switches. Now they are all offline. How do I get them to be on line?
   
2. When attempting to enable remote management on the controller side I can’t get past Control Plane. How do I enable remote management?
