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:

My friends and I are working on Norma. It helps you curate a dataset that captures as much signal as possible for model training.

See norma.grouplabs.ca

Can we establish a convention?

If you sold $500p/m and had costs of zero, then you made $500.

If you sold $500p/m and had costs of $450 p/m then you made $50p/m

I know the saas people have high margins, but some of the commenters clearly have a much lower margin

My parter and I made a fun erotic story generator called Smitten (https://smittenstories.com ) during the valentine's day weekend as a way for couples to spice things up.

Initially it was running on donations, but with model costs rising we had to add a paywall. I have a full time job but it's still fun to run this on the side by spending few hours on it over the weekends!

I've been helping with a small portfolio of Slack apps under the brand https://happybara.io, including Nightowl (multi-DM broadcast for Slack, like BCC for email), and Channitor (channel management & auto-archiving).

It's been a really interesting journey making mistakes & learning from them. One mistake that made me feel foolish: I assumed no one would ever pay for one of the apps. A paywall was added "just in case" -> boom, customers almost immediately started signing up. I felt incredibly silly after that, especially for the number of times I've read on HN and similar sites "your work is valuable" and "charge more".

This is cool! I looked into building a slack app myself, I'm curious: how are you liking the slack store and its policies? Was starting out difficult? I vaguely remember having to have your app installed in multiple workspaces already before being listed in the store

I sell the canvas space within https://www.minigenitals.com to private parties looking to settle scores. Between the coffee's I'm bought and averaging out the monthly "ad buys", it's just over $500/month, usually 3 or 4 $50 2-day campaigns a month and then a bunch of satisfied fans, apparently ¯\_(ツ)_/¯ We recently had to reset the coffee account due to phishing, but otherwise it's been a riot. I think there are a few backed up in the IA

I sell photographic prints. A breakdown of income and costs for this year can be found here: https://leejo.github.io/2025/11/01/print_costs/

TL;DR? It's a grind, an absolute grind.
