Last year, I came across NotebookLM and immediately noticed a pain point: importing the web pages I was browsing into NotebookLM required several steps. So in less than a day, I developed this Chrome extension: NotebookLM Web Importer[1], which allows for one-click importing. As NotebookLM has gained popularity this year, my extension has also seen great growth. So, in July, I added paid premium features to unlock ad…

I really liked your extension having used it in the past. Great job and really useful! If you don't mind me asking, how do you manage the paid features from a technical point of view? Do you give paid users a token to enter in the extension which then activates certain features or is it something else?

https://canine.sh - makes it dead simple to turn your Kubernetes environment into a Heroku like PaaS. Mainly used in organizations with developers who want to deploy to a corporate Kubernetes environment, but don’t want to deal with the complexities. It’s fully open source so we’re covered by sponsors, the largest being Portainer $5k+ / m from sponsorships. Makes it possible to keep the cloud offering totally free.

Is canine for kubernetes as coolify is for docker? Lovely!

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

That sounds awesome. Can you please talk about which premium options you added?

https://dbpro.app I’m building DB Pro, a modern desktop database client for developers who want a fast, local-first workflow. I started in October 2025, launched v1 at the end of November, and just crossed $1k MRR. I also post devlogs of life building and marketing DB Pro and am about to post devlog #4. The latest one is here if anyone’s curious: https://youtu.be/-T4GcJuV1rM Still very early, but it’s been fun seeing…

Loved the design, looks better then the most tools I've tried. I'm using Prisma + Supabase in one of my side projects and having constant db issues. Can I integrate DB Pro? Will it replace Prisma or what?

So DB Pro is a local desktop database client for managing your databases and data. Prisma ORM it won't replace, but Prisma's browser-based data browser, yes it will absolutely replace that. It's not a replacement for Supabase, it works alongside it, if that answers your question?

I'm planning to extend DB Pro into much more than a database manager though, letting you build dashboards, workflows and workbooks.

I’m still selling Computer Engineering for Babies. And I just launched a new book called Simple Machines Made Simple on Kickstarter a month or two ago. Both books are basically just simple interactive demos for kids and adults. https://hackylabs.com

I always see your ads. My first baby is expected to be born next year and I cannot wait to buy it for her

Hi! When will Windows/Linux be available? I'm growing weary of DB Browser for SQLite.

A friend and I host a monthly dinner club for people interested in ethnic cuisine. We work with a single restaurant each month to create an 8-12 course all inclusive price fixe menu. The food is served family style and is authentic to the region we are hosting. We typically host the dinners on a Tues or Wed when the restaurants in our region aren’t too busy and could use the extra business. Since 2023 we’ve been to 4…

Out of curiosity, if you don't mind sharing, what is the sort of profit you see on that 126,000 as i'm assuming alot of that goes to paying the restaurants?

This is so cool! As someone who loves trying out new restaurants I need to ask: why would I go with you guys instead of going to the restaurants myself with a friend or partner? Looking around your website it seems to me that there's very large attendance, which in my mind means generally less focus on the food itself. Do you think one of the main factors is meeting new people/the sense of community? Anyway good job! I'm not sure what your margins are but it's probably more than 500/month! Congrats!
