Ask HN: Those making $500/month on side projects in 2025 – Show and tell

It's the time of the year again, so I'd be interested hear what new (and old) ideas have come up. Previously asked on:

I put sponsor information on my open source project, and it has been giving me $600/mo in the past few months. There are only a few thousand stars on GitHub, but it's already the most popular tool in a paticular niche area.

What are the reasons to use a throw away account and neither mention the product nor the niche area?

There are 5%-ish code are contributed by other people, I feel really bad for not sharing the money with them. Anyway, I wish that GitHub offers the option to sponsor a project, not one single maintainer.

I run a newsletter called Tech Talks Weekly[1] where my subscribers get one email per week with all the latest Software Engineering conference talks and podcasts[2].

I originally built it for myself because I was subscribed to too many conference channels on YouTube and things started getting messy, so I wrote a script to fetch the new talks automatically. Eventually, I turned it into a newsletter.

I currently have over 7,500 subscribers with email open rate consistently between 32%-35%, although I plan to trim the list soon to get into the 40-50% range.

I recently started offering sponsorship options[3] and made $500 in Nov and $700 in Dec so far.

Making almost exactly $500/mo on an Anki extension that embeds AI / text to speech / image gen deeply into the app, allowing you to generate example sentences, audio, explanations, etc, for whatever you’re studying, in bulk.

https://smart-notes.xyz

Still holding off on the show HN post for now; have a few more features and QoL things I’d like to add first.

It’s been an enormously gratifying project and I hear from users all around the world who have feature requests for their specific use cases. Easily the most fun I’ve had working on a project.

It looks like a great idea. Kudos on the work so far!

May I ask which channels / approaches benefited you the most in terms of reaching your first paying customers?

piazz 12/18/2025||
Thank you!

Almost all of my customers so far have been directly from the central Anki plugin directory. I made sure to use lots of SEO friendly terms / buzzwords in the title so that when people ctrl+f for AI or ChatGPT, they find mine.

My next steps I think are to better incentivize leaving reviews so that it ranks higher on the add-on list, and then launch it on various language learning subreddits. There’s a whole cottage industry of Anki influencers on YouTube as well (absurd, I know), so that’s another channel eventually.

Formester started as a side hustle but today we make $7000/month.

All I wanted was to build a good product which our users feel like using. Help them with exceptional customer service and build a team and a company worth waking up to.

But you didn’t say what you are making!

This is huge, actually I have used this before the free version, is this a 'side-project' or do you have some staff because it seems a big operation. Nice job.

I started running AI workshops this year [1], stemming from work that I do teaching at a non-profit in New York. [2]

I've spent a lot of my life teaching people, but for the last 2-3 years I've been fascinated with AI. I'm not in the "Sam Altman is building a digital god" camp, but I've seen how amazing AI is by watching people who have no technical background build products, launch their own businesses, and change their lives in under 9 months. It's pretty remarkable what's already possible, but not everybody knows or believes that.

I set out to find a niche when it comes to teaching: I make AI more accessible to regular people. A lot of what's written about AI is unbelievable — either because people say AI can do things that it cannot or because people say that AI cannot do things that are already possible today.

I've been bridging that divide one workshop at a time. They've spread very well by word of mouth because there are no tricks here. People bring an idea that they want to build, and we do that in three hours by learning the mental models and communication skills necessary to work with AI in a short period of time.

I've had a few workshops every month since I started in April, which is remarkable as an indie who's been trying to earn a living by helping people. I'm grateful to my friend who sat down with me for what became my first workshop, and helped me start this new line of business.

It's very gratifying to hear a PM with great ideas tell me "I have a new hobby that I can't put down". That's what I mean when I say I'm making AI accessible — people are this close to manifesting the ideas in their head the way programmers have been able to for decades — they just may need a little bit of guided learning.

Around 3K/m with my side projects: https://tools.dsebastien.net

Revenue from courses, apps, community, books...

Still not able to pay myself anything though

I'm not quite at $500/mo yet (just launched the waitlist), but this is my attempt to get there in 2026.

I'm building Snaption (https://snaption.cc).

It solves a specific pain point I had as a developer: "Screenshot Chaos." I take dozens of screenshots daily (bugs, UI inspo, code snippets), but manually tagging and organizing them into Notion was too much friction.

Snaption automates this:

Shortcut to capture.

AI analyzes and summarizes the content.

Auto-syncs to Notion.

The stack is Next.js + [Insert your specific tech here, e.g., Supabase/OpenAI].

I'd love to hear feedback on the landing page or the core concept from the community here.

Microlandia - The Brutally honest city builder.

I started making this game several years ago, sporadically, abandoning it for month-long periods, but after posting it here a few times in Show NH I got the encouragement I needed to publish it to itch.io, then to Steam.

This month it crossed the $500/month mark by far, but it was a long road to get it to a state where it can actually be an interesting enough game to make money.

I'm curious, what happens if you allow much more unlimited zoning to begin with in a city? Do you have ways to model decreasing regulatory burden for new development?

A platform for digital asset management, review and workflow. Current features focus primarily on review of images aimed at automotive configurators.

The problem is generic, however, our USP is we have a couple of enterprise customers that upload packs of 60k+ assets for a round, and thus we aim to help discover what demonstrably changed.

A bit like Github, only working with images, videos, and other digital assets rather than text files.

I built an accounting app :

https://compta.libremen.com

Did not intend to at first, but having quit Windows, I had to replace the Access application I had built with an accountant friend of mine to manage my small business. Looking around the web, I could not find something I liked.

I ended up re-writing the thing as an SaaS for my own use, but then figured that if I'm using it, others might want to, and all I had to do was to add an 'id_client' field to the database. It turns out to be a bit more complicated than that, as users tend to come with different needs, and to think of ways of using your app you did not anticipate.

Also, when I tell an accountant that I wrote an accounting application, his eyes pop, his head tilts slightly, and he appears to be evaluating whether I'm the dangerous kind of crazy before ending the conversation. Must be due to the horrors they have to deal with all day.

It's a hard sell, revenue is closer to $500/year than $500/month, because I have very low fees and very small clients. But I take great pride in counting one accountant using it in his professional practice. It's also great fun to tune as the number of lines grows, however odd this may sound.
