You should always use a swap file/partition, even if you don't want any swapping. That's because there are always cold pages and if you have no swap space that memory cannot be used for apps or buffers, it's just wasted.
Sometimes that crashing is what I want: a dedicated server running one (micro)service in a system that'll restart new servers on such crashes (e.g. Kubernetes-alike). I'd rather have it crash immediately rather than chugging along in degraded state.
But on a shared setup like OP shows, or the old LAMP-on-a-vps, i'd prefer the system to start swapping and have a chance to recover. IME it quite often does. Will take a few minutes (of near downtime) but will avoid data corruption or crash-loops much easier.
Basically, letting Linux handle recovery vs letting a monitoring system handle recovery
Yes, it has some things that behave differently than PostgreSQL but I am curious about why you think that.
Does the difference matter? You must decide that.
As for your dismissing SQLite: please justify why it’s a bad idea. Because I strongly disagree.
If you plan to remaining smaller than instagram, the ceiling is comfortably above you.
The go equivalent of just coping one file across to a server a restarting its process has a lot of appeal and clearly works well for him.
It is not. Simple. It may be "easy" but easy != simple (simple is hard, I tend to say).
I'm currently involved in a project that was initially layed out as microservices in rust and some go, to slowly replace a monolyth Django monstrosity of 12+ years tech debt.
But the new hires are pushing back and re-introducing python, eith that argument of simplicity. Sure, python is much easier than a rust equivalent. Esp in early phases. But to me, 25+ years developer/engineer, yet new to python, it's unbelievable complex. Yes, uv solves some. As does ty and ruff. But, my goodness, what a mess to set up simple ci pipelines, a local development machine (that doesn't break my OS or other software on that machine). Hell, even the dockerfiles are magnitudes more complex than most others I've encountered.
Honestly, yes. I'm on HN for tech content, I don't really care about startups and the business side of things, even though sometimes there are interesting reads on this side as well. Also, it may very well be the case that I rediscover the meaning of MRR for the second or third time in sixteen years :).
Its like not having syphilis or cancer, its a good thing.
Initially from the title, I thought it would be about brainstorming and launching a successful idea, and that sort of thing.
Which obviously works, it's not like there aren't tons of multi-million startups ultimately doing the exact same thing, and yet. It feels a bit... trite?
Dead giveaway
What do you want VC to do?
You didn’t bring a plan.
In my case, I've used a similar strategy of keeping costs under €100/month. (But have sold, or stopped my ventures before hitting such MRRs as OP reports).
I raised some capital to pay my own bills during development. But mostly to hire freelancers to work on parts that I'm bad at, or didn't have time for: advertising, a specific feature, a library, rewrite-in-rust (wink) or deep research into functional improvements.
One note: you can absolutely use Python or Node just as well as Go. There's Hetzner that offers 4GB RAM, 10TB network (then 1$/TB egress), 2CPUs machines for 5$.
Two disclaimers for VPS:
If you're using a dedicated server instead of a cloud server, just don't forget to backup DB to a Storage box often (3$ /mo for 1TB, use rsync). It's a good practice either way, but cloud instances seem more reliable to hardware faults. Also avoid their object store.
You are responsible for security. I saw good devs skipping basic SSH hardening and get infected by bots in <1hr. My go-to move when I spin up servers is a two-stage Terraform setup: first, I set up SSH with only my IP allowed, set up Tailscale and then shutdown the public SSH IP entrypoint completely.
Take care and have fun!
Funny you said that. I migrated an old, Django web site to a slightly more modern architecture (docker compose with uvicorn instead of bare metal uWSGI) the other day, and while doing that I noticed that it doesn't need PostgreSQL at all. The old server had it already installed, so it was the lazy choice.
I just dumped all data and loaded it into an SQLite database with WAL and it's much easier to maintain and back up now.
Once I had Postgresql db with default password on a new vps, and forgetting to disable password based login, on a server with no domain. And it got hacked in a day, and was being used as bot server. And that was 10 years ago.
Recently deployed server, and was getting ssh login attempts within an hour, and it didn't had a domain. Fortunately, I've learned my lesson, and turned of password based login as soon as the server was up and running.
And similar attempts bogged down my desktop to halt.
Having an machine open to the world is now very scary. Thanks God for service like tailscale exists.

Qwen 3.5 and Gemma 4 outperform both of those, and you can run those on your laptop.
And a good portion of the post is focused on running local models, while giving a recommendation to install Qwen 3 through Ollama to get started with them.
Qwen 3 was last updated on Ollama half a year ago. Qwen 3.5 was updated a week ago.
As if there wasn't enough noise in the AI discussion already...
Scaling to zero with database persistence using litestream has cut my bill down to $0.1 per month for my backend+database.
Granted I still don't have that many users, and they get 200ms of extra latency if the backend needs to wake up. But it's nice to never have to worry about accidental costs!
Hetzner / Contabo maybe. Cloudflare workers definitely.
This guy is not at my level and multiple $10k MRR is possible but unlikely.
I don't want to diss SQLite because it is awesome and more than adequate for many/most web apps but you can connect to Postgres (or any DB really) on localhost over a Unix domain socket and avoid nearly all of the overhead.
It's not much harder to use than SQLite, you get all of the Postgres features, it's easier to run reports or whatever on the live db from a different box, and much easier if it comes time to setup a read replica, HA, or run the DB on a different box from the app.
I don't think running Postgres on the same box as your app is the same class of optimistic over provisioning as setting up a kubernetes cluster.
Isn't this idea to spend a bit more effort and overhead to get YAGNI features exactly what TFA argues against?
Running 100,000 `SELECT 1` queries:
PostgreSQL (localhost): 2.77 seconds
SQLite (in-memory): 0.07 seconds

Really? Lol. If it's true why would you publish it? To ensure Microsoft will patch it up and fuck up your workflow?
It's true and it's their official pricing, so talking about it won't change anything.
People are spending way too much money with Claude Code while they could simply pay for GitHub Copilot and fire up OpenCode to get the same results but way cheaper.
I have been doing this kind of thing with Cursor and Codex subscriptions, but they do have annoying rate limits, and Cursor on the Auto model seems to perform poorly if you ask it to do too much work, so I am keen to try out laconic on my local GPU.
EDIT:
Having tried it out, this may be a false economy.
The way it works is it has a bunch of different prompts for the LLMs (Planner, Synthesizer, Finalizer).
The "Planner" is given your input question and the "scratchpad" and has to come up with DuckDuckGo search terms.
Then the harness runs the DuckDuckGo search and gives the question, results, and scratchpad to the Synthesizer. The Synthesizer updates the scratchpad with new information that is learnt.
This continues in a loop, with the Planner coming up with new search queries and the Synthesizer updating the scratchpad, until eventually the Planner decides to give a final answer, at which point the Finalizer summarises the information in a user-friendly final answer.
That is a pretty clever design! It allows you to do relatively complex research with only a very small amount of context window. So I love that.
However I have found that the Synthesizer step is extremely slow on my RTX3060, and also I think it would cost me about £1/day extra to run the RTX3060 flat out vs idle. For the amount of work laconic can do in a day (not a lot!), I think I am better off just sending the money to OpenAI and getting the results more quickly.
But I still love the design, this is a very creative way to use a very small context window. And has the obvious privacy and freedom advantages over depending on OpenAI.
But, actually you can run Kubernetes and Postgres etc on a VPS.
See https://stack-cli.com/ where you can specify a Supabase style infra on a low cost VPS on top of K3s.
I guess it’s all about knowing when to re-engineer the solution for scale. And the answer is rarely ”up front”.
You do get Opus 4.6, and it's really affordable. I usually go over my limits, but I'm yet to spend more than 5 USD on the surcharges.
Not seen a reason to switch, but YMMV depending on what you're doing and how you work.
Thinking about on how to fit everything on a $5 VPS does not help your business.
I recall running LAMP stacks on something like 128MB about 20 years ago and not really having problems with memory. Most current website backends are not really much more complicated than they were back then if you don't haul in bloat.
That's 17 million hits per day in about 3.9 MiB/sec sustained disk IO, before factoring in the parallelism that almost any bargain bucket NVME drive already offers (allowing you to at least 4x these numbers). But already you're talking about quadrupling the infrastructure spend before serving a single request, which is the entire point of the article.
And, not sure I'm correct, but I felt Postgresql has more optimized storage if you have large text data than SQLite, at least for me I had storage full with SQLite, but same application on Postgresql never had this issue
Here’s the more honest one i wrote a while back:
> Infrastructure: Bare Server > Containers > Kubernetes
The problem with recommending a bare server first is that bare metal fails. Usually every couple of years a component fails - a PSU, a controller, a drive. Also, a bare metal server is more expensive than VPS.
Paradoxically, a k3s distro with 3 small nodes and a load balancer at Hetzner may cost you less than a bare metal server and will definitely give you much better availability in the long run, albeit with less performance for the same money.
Why do I know this? Because there had to be a declaration here to stop using ChatGPT and other Agents to write YOUR OWN GODDAMN POSTS. Thinking isn’t your strong suit, Greed is, and taking the time to learn the power of English doesn’t satisfy the latter, so you minimize it to your own detriment.
Don’t get mad at me. Go punch a mirror.
Not clear from the text, but what was your plan using the funding on? If you did not have a plan, what did you expect? VCs want to see how adding more money results in asymmetric returns.
Saying "you can just run things on a cheap VPS" sounds amateurish: people are immediately out with "Yeah but scaling", "Yeah but high availability", "Yeah but backups", "Yeah but now you have to maintain it" arguments, that are basically regurgitated sales pitches for various cloud platforms. It's learned helplessness.
It starts about cutting costs by the choice of infrastructure and goes further to less resource hungry tools and cheaper services. But never compares the cost of these things. Do I save actually the upgrade to a bigger server by using Go and sqlite over let's say Python and postgres? Or does it not even matter when you have just n many users. Then I do not understand why at one point the convenience of using OpenRouter is preferred over managing multiple API keys, when that should be cheaper and a cost point that could increase faster than your infrastructure costs.
There are some more points, but I do not want to write a long comment.
$20/month. Yeah. Great, but why? You get a lot of peace of mind with "real" HA setup with real backups and real recovery, for not much more than $20, if you are careful.
Another half of article is about running "free, unlimited" local AI on a GPU (Santa brought it) with, apparently, free electricity (Santa pays for it).
This is really what 10k mrr can get you? A badly designed AI slop website that isn't even mobile correctly compatible. The logo is white background on black website like a university project.
I can't believe that people are willingly spending money on this.
If you get one dedicated server for multiple separate projects, you can still keep the costs down but relax those constraints.
For example, look at the Hetzner server auction: https://www.hetzner.com/sb/
I pay about 40 EUR a month for this:
Disk: 736G / 7.3T (11%)
CPU: Intel Core i7-7700 @ 8x 4.2GHz [42.0°C]
RAM: 18004MiB / 64088MiB
You could have 15 VMs each with 4 GB of RAM and it would still come out to around 2.66 EUR per month per VM. It's just way more cost efficient at any sort of scale (number of projects) when compared to regular VMs, and as long as you don't put any trash on it, Proxmox itself is fairly stable, being a single point of failure aside.
Of course, with refurbished gear you'd want backups, but you really need those anyways.
Aside from that, Hetzner and Contabo (opinions vary about that one though) are going to be more affordable even when it comes to regular VPS hosting. I think Scaleway also had those small Stardust instances if you want something really cheap, but they go out of stock pretty quickly as well.
