DISCLAIMER: The term low-end is subjective, this is intended to help anyone with a less than powerful pc.
For the past few months I've been using a laptop with 4 GB RAM for working, learning and just about everything. My experience plus this twitter thread by Brad Traversy (Who is a great teacher btw) sort of inspired me to write this. Turns out that there are LOTS of developers with high end PC's but also lots of developers with arguably low end one's as well.
If you were just starting out or even a professional programmer, you'd imagine you'd need a lot of stuff. If you ever have to, it's 100% possible to code with a low end PC.
NOTE: Most of this applies to web application development. If you are developing games or training machine learning models locally then idk man, hopefully someone in the comments can help. (although i know google colab works for machine learning)
The Editor
Programming largely involves typing text and hoping the text makes sense to the computer, preferably with tools that make this easier. Most full on IDE's take up lots of RAM, which is a resource we can't really spare especially when you have other things open like several browser tabs.
The solution: A code editor, not an IDE (anti-climactic, I know.)
Local Editors's
Visual Studio Code
This is a very popular code editor that is "IDE like", it's lovely. Although a computer with around 2-4GB of RAM can run it. It isn't exactly known for being conservative with RAM. Here are some things you can do:
Tip 1: Disable unnecessary extensions!
I used to have some extensions on that weren't exactly relevant to what I was doing. Disabling them will should reduce the memory footprint of VSCode. You can find out how to do this here. After my research, this really is one of the best approaches when using VSCode.
Excluding files from filewatcher
You can stop VSCode from "watching"/tracking certain files for changes. You can do this in your VSCode settings . By default it has stuff like node_modules and git objects excludes but you can use a glob pattern (A useful guide on them) of file paths to add any thing else there.
"files.watcherExclude": {
"**/.git/objects/**": true,
"**/node_modules/**": true,
//Add in your other glob patterns
}
A few people have suggested sublime text so you can give that a try.
This is all great. However, If you have even lower specs or are working on a somewhat larger project, your PC may start to struggle if you have other things open. So switching to an even lighter editor would help. There are many great ones: some suggestions are Notepad ++ OR VIM.
Regarding something like VIM, while it is really lightweight, it takes sometime to get really good/efficient. Once you do learn, it is really nice not having to touch your mouse as much. Also when you code it makes you look like every non-programmer's idea of a programmer.
Upside is you don't have to touch your mouse as much, The downside is that you have to learn vim :*
Another Solution: Online IDE's
Here is another avenue that is great for several purposes. Online IDE's are pretty nice now. This especially true if you develop with many programming languages (Like PHP) and can't be bothered to setup a local dev environment. You also get the freedom to write code on anything with an internet connection.
They also happen to be pretty great for sharing code and working with other people quickly. Most computers have some browser and that's all you need.
There are a few options: Repl.it from my personal experience is pretty amazing, they support so many languages and allow you to run code and use a custom domain for your work. Plus multiplayer!
Codepen is another option which is pretty popular for sharing HTML./CSS/JS code, I used it a lot when I first started out with web dev about 3-ish years ago. There is also Codesandbox, which looks good, it appears to be a VSCode editor in the browser.
(I may be missing a few other good online editors but these one's are top of mind)
Extra Tools/Tips
Storage
Many low end PCs are at times plagued with low storage space. The best advice I have here is to only store projects you work on 24/7 on your machine, instead just commit the files to git and push to a hosted or self-hosted repository.
Chrome Extensions
The Great Suspender
While I did mention keeping extension/plugins to the absolute minimum. Because programming often involves a lot of open browser tabs (Which you will most likely hoard or forget to close). I recommend this extension.
Like the name suggests, it suspends idle tabs (you can configure how it works and exclude certain tabs based on some features).
An adblocker (ublock Origin)
I think most people who work anywhere near tech already have this. If you don't many sites loading trackers can have an impact on browsing speed. So this comes in handy.
Browsers & Browser Windows
Although I can't really give you the textbook explanation. One thing I do is work in a window where I am not logged in to anything. Not only does this help productivity but generally it makes my browser run faster, even searching stuff gets faster as well (my guess is that over-personalization can make things sluggish).
Final Thoughts
When you think about it most people who actually use what you make may not be on the best computers in the world so I guess you get to live their experience and avoid unnecessary fluff.
Whenever you are able to, upgrade your computer! it'll probably be a decent investment. From my experience the most important specs are RAM and SSD.
There are probably a million more little things you can do to make your computer more efficient. If you have any other tips, please leave a comment . I can edit the post and cite you :)

Great comment Phil, definitely agree with you there.
If you have low end PC, first advice: dont use vs code. Use Sublime text :)
Yup. I used to use Sublime Text for just that reason (though in my case it was a case of wanting something that would work well inside of Lubuntu running under VirtualBox on an old, non-virtualizing Windows laptop. VSCode was too sluggish for that, but Sublime Text did fine. I have since upgraded both laptop and desktop to faster, virtualizing machines, and have switched to VSCode. Right now, VSCode's Remote-SSH implementation is keeping me there.
Thank you mate, VSCode gets quite lagged sometimes, gonna try Sublime Text. Hopefully I'll get a different laptop to work with in the next few months...
I can say the reverse.
Learning Vim is... fun! Stress reliever when the Jira Task «In Progress» is >3 and you've feel too much.
Having learned not to use mouse is an endless pit of dismissing actually good software because of poor keyboard support.
Written with Vimari, an emulation of Vim for any
<input>.Vim is great now that I know how to use it decently enough. I guess that was mostly referring to the learning curve for becoming an efficient user.
Starting out, you work slower during the learning period but I think after a few days, vim starts to pay off. After a few months (and years I presume), the value is undeniable.
That's why Vim is so good. It's fun.
Many lost themselves in endless discussions about fast and slow and mouse and keyboard. They forget something really important: fun will always make your more productive.
Vim is the gamification of coding.
I never heard this before :D this is my new favorite nonsense for vim, I definitely will quote you :D
(to be frank, it is really good on many places, but it is just a mature text editor)
On the fun angle, mandatory mention to vim-adventures.com/ :)
The one thing I really like about Vim is that it is a zen-like experience for me. I truly become one-with-the-keyboard. The editor is out of the way — out of sight, out of mind. I never have to touch my mouse, even if I'm using a graphical Vim. Fingers on home row the whole time. It's magical. Maximum throughput, although most programming time is thinking rather than typing (but there is heavy output typing in bursts).
this is also true to me, and affect my apps preference greatly.
I abandoned many great apps because they have poor support for keyboard movement. In minimal, they has Emacs style movement (
C-b,C-n), but force me to reach to keyboard to use sidebar.Using (Neo)Vim, I am the master of refactor for my project, because like any article you’d found in the internet, programming is more reading & editing rather than writing. Vim provides convenience for reading, editing and writing. Vim(like keybinding) is good.
Thanks for your post.
If you are developing a mobile app, use bitrise and fastlane to compile in the cloud. You don't need to invest in a mac :)
What specs would be considered low in 2020?
That's tough, my judgement is a bit off at times because while I am a developer I also play video games and edit videos occasionally (So for the things I want to do 4GB is low, but good enough for the most important thing I do: mostly programming).
It really depends, ballpark for me is <4GB RAM.
Yup, I was thinking the same! Something in the lines of dual-core cpu below 2ghz, <4gb ddr3 ram, low capacity 5400rpm hdd and some integrated graphics...
This is the precise spec of the pc I use for Web dev
Sadly I'm using a notebook with similar specs.... work gets tedious.
I would say, try to code on a rapsberry pi 2b+, with desktop mode. But fine if you can think of an older platform under pc, like a core2duo (because early "i" series is still perform well). Or an ultra version of low-end cpu. Imho.
Another solution: Spacemacs :P
Sublime Text was the only editor that worked well for me on my 1.1 gHz, 4 gb ram trash pc, glad I now can use VS Code on better pc.
The used market is flooded with office OEM computers that were cycled out by companies. You can get a second gen i5 with 8GB of RAM for very convenient prices. If you make any money from your coding, you should look about getting at least something like that. You will thank yourself later.
I have been working on such a machine for about 5 months until the current crisis started: a Dell Optiplex, with an i5 2400 and 8GB of RAM (that later got upgraded to 24GB with two extra sticks of 8GB). It is more than capable to run PHPStorm, Photoshop and a bunch of browser tabs.
Take a moment to look on eBay, Facebook market, Gumtree or whatever portal is there in your country for selling and buying stuff. Just because you can't afford a new computer, doesn't mean you have to suffer using an ancient and underpowered one.
I actually dont suffer from a low end PC as I spent quite a bit, however, I actually do all of my programming on gitpod.io. It's an amazing online code editor that is basically VS code hosted for you. I would say it's probably the same as what github codespaces will be when that releases. I have to say though I am looking forward to github codespaces.
