I run a porn website that gets me around $1000 a month now. I'm doing this for about 5 years and it started as a side project to learn more about hosting, SEO, and monetization.

This was a simple Wordpress site, but then eventually I rebuilt the whole thing with Nextjs and tailwind because Wordpress was just too damn slow. In the process, I ended up building a custom CMS, which I'm now working on a white label version that I could sell in the future.

I'm hosting the whole thing on a VPS that costs about $30/month and have videos on cloudflare R2 for about $15/month.

How are you dealing with porn verification laws? I have an idea for something porn related but it feels like there is a lot of red tape now that I don't want to deal with but I haven't done all that much research into it so I am probably wrong

My portfolio of iOS apps ends up at an average of $500/mo.

Most are older, still functional but rarely updated. A few of the newer ones include:

https://daylightgoals.com - Time in daylight tracker, using Apple Watch/HealthKit as the data source.

https://airlauncher.app - App launcher for visionOS - was much bigger last year before Apple added the ability to organize your apps.

https://itunes.apple.com/us/app/ibuzz/id304684758?ls=1&mt=8 - iBuzz - I built this app in a day 15 years ago, it still makes about $100/mo from ads and removing ads. Just a simple buzzer soundboard app.

How’s the developer experience on AVP? Any surprises, positive or negative?

Did you find the tooling and documentation from Apple sufficient?

Sadly not $500/mo, but I do get a few sales on https://dailychinesestories.com each month. It's as simple as it sounds - a story in Chinese at your HSK level for your preferred themes once a day.

I run drawcharts[1], which is a tool to help you build good looking hand-drawn style charts. It is not very expensive so I am currently making around 500 a year from it.

Also, as someone who likes to go to conferences and meet and connect with people, I found it hard connecting to 50 people at a conference on Linkedin and then reaching back out to them. So I build LinkedMemo[2] which is a CRM on "top" of Linkedin. You scan a profile, the profile is automatically saved and enriched in the CRM with a quick note.

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?
throwaway5757 6 days ago||
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.

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.

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 6 days ago||
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.

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 make between $400 ~ $600/mo between these two:

Disk Prices on eBay - https://unli.xyz/diskprices/

Digital Film Stock - https://unli.xyz/digitalfilmstock/

Both are very similar... just a lot of regex (200+ expressions) to parse eBay item titles and descriptions

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

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?
