What are your favourite, or least favourite but necessary, cost-cutting methods?
I feel I am spending too many resources on unnecessary stuff.
Edit: I feel the need to reduce both – the resources, to host multiple things on one system, and cost, to buy/pay for multiple systems. Currently, I have 2 ARM VPSes and 1 old MacBook Air as a home server.
Fasting allows you to waste less money on food and invest more money into your server.
When I was younger, I’d save my lunch money for weeks to buy a game and fast during school. I’d do my best to fill my stomach with as much water as I could.
You only need to eat two meals a day, really.
OMAD (one meal a day) and intermittent fasting is even healthier
Cost-cutting is corporate-greed mindset, therefore you have to solve it with the same mindset.
Fire people ! Even you if needed. And let the end-users deal with the outcome.
(This is not a serious post ^^ )
Make a spreadsheet of where your money is going.

Or then you can just realize that the time you spend is spent not making money and you need to save time, not services.
My favorite cost cutting tip is to avoid big webapps running on docker, and instead do with small UNIX utilities (cron instead of a calendar, text files instead of note taking app, rsync instead of a filehosting dropbox-like app, simple static webserver for file sharing, etc). This allows me to run my server on a simple Raspberry Pi, with less than 500mb of used RAM in average, and mininal energy consumption. So, total cost of the setup:
- Raspberry Pi : 77€ x 2 = 144€ (I bought two to have a backup if the first one fails)
- MicroSD 64gb : 13€ x 2 = 26€ (main and backup)
- average energy consumption : 0.41€ (2kWh) per month
With that, I run all services I need on a single machine, and I have a backup plan for recovery of both hardware and software.
Getting used to a UNIX shell and to UNIX philosophy can take some time, but it’s very rewarding in making everything more simple (thus more efficient).
cron instead of a calendar
What do you mean by that?
Do you use crontab to save events?
Basically, yes. You can configure most cron programs to mail task output to you (it’s usually done by setting the
MAILTOvariable in the crontab, provided sendmail is available on your system).I use that to do things like:
0 9 11 10 * echo 'lunch with John Doe at 12:20'It sends me a mail, and I can see the upcoming events with
crontab -l. If it’s not a recurring event, I then delete the rule.Damn, I’m doing *nixes for nearly 30 years. But never went to that level of minimalism. Nice trick.
And to expand further on simplicity, one can avoid using email and send messages over ntfy with just a POST curl call.
I like your setup!

Yeah, and that’s the problem for me. See my comment above. Nextcloud and those services are “bloated”, yes, but very convenient. I never worked in an IT-environment, so I’m a total noob.
But stuff like NC AIO give me a whole pre-set-up LAMP stack without needing to know how everything works, and that’s unbelievable for me.
Honestly I’ve worked in technical fields (either support or engineering) for most of my life and sometimes I don’t feel like reinventing the wheel. Sure I could combine rsync and crontab and sync files around that way on a regular basis, add lighthttpd for web browser access to the folder, and I do sometimes, but I’d also like to do things OTHER than more work. I know how to do those things, but I don’t want to do those things.
Ask yourself what part of this is your hobby. Is it building the thing and making it do as much as possible with as little as possible? Is it getting a self hosted cloud that’s polished like Google’s? Is it something else like photography or music and this is just the way you want to share or archive that? Those are all three different scenarios and is make different suggestions for each.

Running stuff on my bare metal servers is my go to cost saving measure. Why rent 2 VPSes if you can buy some old thin clients and turn them into linux servers, etc.
Two reasons, basically. First, I am behind CGNAT. Second, electricity in my area is somewhat cumbersome, I need some services to be always online.
These days you can use various services to expose your devices from behind cgnat:
They rely on TLS-termination. I self-host for privacy, so I need TLS-passthrough. Cloudflare wants me to buy their enterprise plans for that.
Im quite new in selfhosting, but I highly recommend power meter for home server if you dont have one. Its easy to tell the difference after any change in your setup. I was surprised with numbers when I was testing different PSUs on DIY PC. All PSUs were overkill (550-750W) for my tiny server (they are not made for that low power), but some cheap models were better than more expensive PSU. I was meassuring from 22-28 W iirc on idle. Its only 6W difference, but thats like 25%. I dont use VPS because I have no need for that and even cheap ones are more expensive than running my home server. Some servers can run at <10W and raspberry pi use even less power
- Use sqlite instead of Postgres, MariaDB
- Avoid enterprise software (Kubernetes, Elastic Search)
- Only use projects with efficient programming languages such as Go, Rust, etc.
- Try to run things bare metal
- Lookout for projects which name themself minimal or light-weight
I use a Raspberry Pi 2 to self host a Dashboard written in Rust (Axum), a RSS reader called yarr and a music streaming server Navidrome. The latter two are written in Go and very resource efficient. The electricity bill should be under a Euro a month (6.4W max power consumption).
While I don’t agree with your first point from my experience, the second one is very true. Especially for memory consumption, your typical Java app easily occupies five times as much as something more bare metal.
My least favourite (and only) method for me to cut costs is reduce my energy consumption.
I already have a super cheap setup (used Mini-PC for 50 bucks, old SSDs I had lying around, etc.), so reducing the hardware costs more isn’t possible.
But, without tweaks, this setup would eat 15W (idle) and 25W (under load) electricity. At least, thats the case atm.
I just started selfhosting to be fair, and I didn’t have time to throttle the server. I use it mainly as NAS, so speed isn’t as important in this case as for other services like webapps, where reactivity is needed.
The CPU isn’t too bad, so, even when reducing the performance to 50%, it should still work.
Also, I will try to change the active cooling fan to a passive heat sink, that might reduce the bill further.
What mainly eats resources like crazy is my Nextcloud AIO. I try to follow the UNIX-principle as good as I can, and NC doesn’t follow it well, at least for my use case.
I only need a file server, and NC is pretty “bloated” with talk, calender, and so on. So I disabled all of that.
But, I’m not capable enough to set up an Online-FTP-Server and secure it enough without ever working in that environment. NC AIO provides a lot of comfort and “just works”. So, I’m fine with that.
Here in Germany, especially thanks to the energy crisis, electricity is absurdly expensive, and even reducing the TDP by a few % will save me much money over a year.
So, I try to reduce the load and increase efficiency wherever I can.
Still, even now, with an increased energy consumption + paid domain, it’s still cheaper than using OneDrive or something like that, even when ignoring storage size.
sftpgo is a nice project to host files in a secure way without too much hassle.
