Ask HN: How do you come up with side project ideas in 2024?

86 points by nidnogg ↗ HN
Hi everyone. For the longest time I've been wanting to get a few ideas of my own that I've written down actually built up and deployed.

I wanted something that I could maybe make some beer money off being useful for people, and something that could use an actual back-end to improve my back-end skills. I wanted to consolidate my Rust (or Golang) skills as well.

But whenever I write something down, I get a bit carried away when implementing it and never really finish much. I also discard a lot of ideas because they end up being too simple (and too front-end-ish overall). I'm starting to think the root of the issue could be the ideas themselves that are too lackluster.

So I know this has been asked before (I've combed over those old threads countless times and they've been helpful), but I'm curious to hear more thoughts on the subject.

I am developing a side project these days. This what I've got since now: 5-30 seconds deploy time, end to end type safety from db to the frontend, 100 lighthouse score, automatic let's encrypt certificates for my docker machines, 50kb total webpage payload. And of course nothing of real value done. I guess we are all on the same boat :)
I’m curious how to auto-renew lets encrypt certs, do you mind sharing the tips? Thanks
I am using nginx-proxy (look it up on github) . It hasn't been that simple to put together, I will investigate MicroK8S in the future.
What are you using for end to end type safety? Currently enjoying the same on a side project with Postgres -> GraphQL (Hasura) -> Golang (genqlient) & Typescript (graphql-codegen)
I gave up Graphql due to buggy/obnoxious vscode plug-ins, also I would pass over code gen if I can.

I have a simple setup with pg+drizzle+zod+trpc. I don't like the libraries that much, but it overral works very well.

I'd prefer something simpler, more ergonomic of all those components, but the basiline is that for now.

Carry on, boatmate!

It seems like you have more of a problem scoping things and finishing them.

I would suggest going ahead with one of your ideas (if you can't pick, roll dice, pick a note out of a hat, etc) and take it to MVP.

Finishing things can just be a habit, anxiety and perfectionism are the enemies of getting things done. You also don't know what will or will not be successful. Focus less on what you think will happen and more on getting things done. Do it once or twice before you worry about how good an idea is or how much potential it has.

Some starting points:

- Find old datasets (hn.algolia.com "datasets", use huggingface, search arxiv)

- Use weird search engines, e.g. exa.ai (searches based on embeddings vs. google's pagerank/keywords) + google dorks. weird input = weird output

- mix 2 ideas you see - look at showcase channels on discord and pages on random frameworks, things people are building at Buildspace

- Find old facebook groups with lots of grumpy members posting regularly

These are just random strategies I use before I make things I post on twitter (https://twitter.com/joshelgar), but they work pretty well for coming up with fun projects.

Thanks, these sound good. I don’t understand the one about “finding fb groups with grumpy members” - what then?
Often 40+ yr old people complain about problems that you can solve e.g. vet technicians don't like veterinary software - you can fix that somehow.
How do you find grumpy men facebook groups? I would love a strategy
1. GPT4 "500 tough professions w/ hardship involved" 2. Multiply that with "500 shifts in <profession> or <industry> regulations> since 2000" 3. Get inspired to come up with - grumpy fisherman mad about mooring fees, dog walkers upset about walking limits, 10x increases in flytipping in blackpool 4. As your ideation improves, train a better gpt.

Frankly all those FB groups (min. names) are probably in the GPT training set, just a case of finding good prompts to get inspiration.

Like in 2023, 2022, etc. by having a real world need.

Idea is 5%, finishing is 95%. I say take one of your previous projects and see what it takes to call one of them finished. Do it. It will change your outlook.

I have 20+ projects from 2010-2015 which I abandoned. Recently I went over all of them and found one which I relaunched at https://appsjhola.com and I have another one that I got paid for working in the past which might take off. I am talking with people if they'd want something like that.

I too recommend giving your previous project ideas a fresh look.

> I also discard a lot of ideas because they end up being too simple

No idea is too simple. Apple has been iterating on the iPhone timer for like 10 years.

Ship a simple idea that people want and will use. Feedback will make it complicated and more work, don't worry.

My passion projects, I don't expect them to make money. I do them because I want to create something and because I think it's useful. For eg. I am working on a website that will be of great help to students and teachers of a certain field (keeping it vague for anonymity), and I have taken an explicit decision for it to be to be free and ad-free forever.
This is how I do it too. I build websites for other people for a living, so if I have a side project I just want to build something I like. And if I don't worry about making money with it, I don't feel the pressure to build for others and can do it for they joy of creating something. Which is why I got into this profession in the first place.
Talk to people about what pains them and work backward from there. You'll probably find a thing or two where simple things can be done that'll have a big impact.
What is the goal ? If you planning to monetize it then pick up an existing successful app. Strip down the functionality and cater to a niche set of users. Develop something very fast. Get on twitter and broadcast it, dm potential users.

First ideas usually suck. It is the second, third, fourth ideas that will get traction.

Thinking of unique idea is usually a kind of procrastination. There are lot of apps that just suck. Copy the idea and make it better, faster, cheaper, intuitive. DM potential users.

Have a hobby. Then develop or invent a way to program something for that hobby.
I need to do this more. The challenge is figuring out hobbies that I find stimulating that are also social. Though I guess having a cute dog hits that.
Anecdotally, I have been doing that for a number of years and hobbies, without any of my launched projects becoming popular. I guess you also need to actively promote what you’re doing and focus on getting/reaching an audience - unlike me right now.
It’s ok not to finish. Starting, discovering, untangling, solving root node problems can be rewarding and worthwhile. Not every moment’s labor has to feed into a SaaS launch.

Follow problems that bother you and subjects that fascinate you. Those criteria are far more important than product viability or even becoming fluent in tech-du-jour

Beside the jokongly answer gave above, a bunch of ideas:

Look for something that sucks (for example, a decent and free restaurant QR menu web app) and make a better one.

Look for an extremely difficult thing and implement a minimal proof of it.

Look for overpriced services and make a free/cheaper version. (for example: how to create a "add to my calendar" event link that can be sent in a email)

Another thing: write. Write your stupid again and iterate on it. Ask GPT about your it. Ask your friends. Look at it again after two weeks. Make project drafting a project per se. Do it again and again for different ideas. Steal other people ideas, make them better.

> Look for something that sucks (for example, a decent and free restaurant QR menu web app) and make a better one.

This is a great idea, there's a lot of things that people want and that exist but suck.

I just hope that within 6 months to 1 year you'll have found and built something you really enjoy working on and learn from, even if unfinished. Keep going. Positive conviction and optimism. Have faith. I hope you don't think negatively about your ideas and potential because that won't help.

What do you find extremely satisfying working on in programming?

Do you write all the time? It works for me! I keep journalling my ideas in a markdown README.md file publicly on GitHub since 2013. While I was writing I felt inspired by an idea and actually felt I desired to try write some code to implement this idea.

I encourage you! You can write your thoughts down and do small achievable things repeatedly.

I recommend using replit to get an environment quick and ready for programming in. When I was a child I wanted to be an inventor because I liked the idea of creating things.

My interest is low level things such as JIT compilers, database internals and distributed systems.

see my profile for what I've done with this strategy and my programming side projects.

As lame as it is, I don't make side projects until I have a reason to make a side project. My steps are as follows

1. Have problem

2. Look into preexisting solutions for problem

3. Analyze each solution to see if it fully solves the problem in the way I need

4. If none do, make side project

Sometimes, I have many side projects. Sometimes, I have none. My GitHub activity graph reflects this.

That sound rather healthy, not lame.

I get a lot of ideas for project at work, maybe my hobby prototypes get turned into something we run in production, maybe it doesn't. It's all good, it's about the process and learning for me, not really about making money.

>That sound rather healthy, not lame.

That comment of yours about your parent comment also sounds healthy, not lame :)

Sounds like you’re just trying to make money, and preferably fast.

Stop. You’re doing it wrong. Money is the crassest reason to do anything.

Stop the fucking hustle. Make art.

Not really, I phrased it as maybe some beer money precisely because it's not the ultimate reason. I'd prefer to have something useful/interesting/worthwhile first, with some money later if possible.
I only make things I need for myself.

I have a list that just seems to never end of things I want to make for myself. Even simple stuff like a web based notes app where I store my own data. Or the RSS reader I made for myself. I don't care about making money or getting users at first. I make it for myself, and if it's production ready I'll let other people use it.

I'm looking for a notes webapp. Not something overly powerful, I just want something really, really simple where I can drop my stuff. I'd like to try yours.
It sounds like you're fine with coming up with ideas but having issues with sticking to them? Maybe start a company and put a monetary stake in these side projects. Even if they aren't explicitly profitable side projects, it still puts in some imperative.

Also don't be afraid to be the only person using some kind of project tracking implementation like a kanban or whatever with milestones and self-imposed deadlines.

Unless your hobby is making money, I don't think you'll make money trying to make money.. Except maybe by working an actual job.

It seems most side-projects that turn into money-generating projects are made by people who got some idea they're passionate about, rather than people looking for a way to make money (unless their passion is actually the making-money part itself).

For myself, my side-projects revolve around stuff I think is neat, probably the only thing that ever had some potential to make money (and actually did a little bit until I realized making money was not my hobby) was the finalkey.net password manager.

I think you're asking many questions here:

1. How do I finish something?

2. How do I create something other people will find useful?

3. How do I monetize my hobbies?

4. What should I make with Rust?

What answers do you think you need? Maybe you already have the answers. If you wish to do something, do it.

I would suggest only a framework that is essentially to think in prototypes.

1. Focus on quantity, not quality. Make 10-20 things.

2. Think simply. Do some small planning at the outset. Don't expand scope.

3. Release early and often. - Set a schedule, follow it. Release whatever you have when the time is elapsed.

4. Define your goals and measure results in some objective form.

5. After you complete this cycle, find a combination of what you enjoyed and what others are using/enjoying and iterate again.

If I lived ten lifetimes I would never run out of things to build. Each project suggests five new projects along the way.

It’s harder if you think about building for the masses. It’s easy if you think about building for yourself.

But yeah everyone gets creative block sometimes when you’re not on a roll already.

It’s actually crazy the breadth and depth of research that is out there. And in computers, it’s not like math where it’s proven to end here with this proof or whatever. People are just writing papers about something they made. There’s tons of room to get in there and do something new.

>If I lived ten lifetimes I would never run out of things to build. Each project suggests five new projects along the way.

Heh. Same :)

And with combining existing different app ideas or features into new ones (meaningfully), it gets even better. No dearth at all. An excess, actually, as you said.

>It’s actually crazy the breadth and depth of research that is out there.

Totally. Speaks to my point above.

>And in computers, it’s not like math where it’s proven to end here with this proof or whatever.

Ha ha, true. But there are also corollaries, which can sometimes become theorems in their own right.

Joint QED, bro :)

> Each project suggests five new projects along the way.

This depends on the nature project, no?

I've been working for years on advancing the state-of-the-art for spatio-temporal comb filter design for NTSC (SD)TV signals and I've made good progress along the way, but at no point did my project give me additional itches to scratch.

Often it's just things that make your life as a developer easier.
Do you finish them? Because I have the problem that I never finish the things that I work on :D I always come up with another idea and another and nothing gets to the stage for others to actually use it :)
I have also started several side projects and never finished any of them. The problem for me was that when I solved the most important problems, I lost interest in it. This year I'm trying something new and I hope to overcome this barrier. So I can imagine your situation. I wish you to choose a project that you will enjoy and find fulfilling and see it through to the end.
The last software side project I built and launched is a simple iOS app that you can find here: https://www.zone2.app

I came up with this project the same way that most come to me: I solved a problem that I had and then polished it enough that I could release it publicly. I also wanted an excuse to learn SwiftUI and it felt like a good place to do that.

I haven't made much money off of it, but that's fine because I really only built it for myself.

The idea here is that you are tracking zone workouts per week rather than per workout like the default Apple fitness app does?

That's a pretty great example of finding some existing app, focusing on one aspect of that app, and making it better.

For what it’s worth, I find it interesting that the focus is “side project”.

I just try to solve problems. Lots of problems have already been solved satisfactorily if not perfectly. And many more need solving but I don’t have the skills. So I’m looking for the set of problems that need solving that I might be able to help with, and focus on that, but it’s a really small set.

Care less about the idea, and more about the effort. When your goal is to work on something that makes you personally happy, it is something you return to everyday organically. The effort you put in doesn't feel like work. Even if you don't reach your goal, what you have learned makes the next objective/project that much easier. The more you learn, the faster you can iterate, whatever the task may be.
^ This human gets it!

In my experience cool ideas are happy accidents that tend to show up as a side effect of doing something else. The more stuff I make, the more likely I am to have a good idea.

Have problem -> solve problem -> release solution so others with the same problem can solve it.
