I've been putting together a no-nonsense free invoice generator, for people (like myself) that only occasionally send invoices. It's more-or-less a WYSIWYG editor, and the state is stored in the URL, so you don't have to worry about keeping track of where you stored your copy - if you've sent someone an email with the link, you've got a copy. This project was born out of the frustration of trying to generate an invoi…

Nice work! Would totally have used this when I was freelancing. Honestly love the serif'd fonts, would love to see everything serif'd tbh.

Also back when I had to do these (I used Wave) having a notes section was very useful to include a few things (i.e. I used to include conversion rates). Would probably be pretty easy.

I'm building an app for splitting bills with friends, mainly for holidays and roommates: https://quicksplit.io It does one thing and it does it well. I built it with a friend and we released the iOS app last year. Currently building the Android app

I don’t see pricing on the website but the iOS app shows “In App purchases”. Is there a reason why you wouldn’t mention pricing on the website you linked?

I'm building a perp funding arbitrage aggregator. Aggregates funding rates across a number of DEXs to help users track down the most lucrative opportunities. If there is uptake the plan is to build out a toolset to help with managing a portfolio of arbs.

What does this mean? I have no idea what niche you're even working in

I've been working on Zigpoll as a one-man project for a while now: https://www.zigpoll.com/ it has traction and solid growth (~100% YoY for the past 3 years) but the larger the numbers the harder it gets to double each year.

In a past life I would have thought this would be the easy part given the product market fit but it's hard to figure out growth channels that are scalable and cost-effective at this stage. Burning what would otherwise be a large salary month on month in search of growth is mentally taxing when it doesn't deliver. Metrics across the board only seem to tell part of the story so it's tricky to figure out what needs changing and what's worth doubling down on.

If anyone has experience doing this sort of thing - please get in touch!

I use Apple Pencil with my iPad for figures in documents and wanted a better way to sync with my other work... so writing an iPad app for drawings using git for syncing with remote repos. Goal to release in App Store by end of April.

Oh yes please. Do you have a "preorder" on the App Store yet?

No, but I'll look into that as I get closer to having something ready.

I'm a synthetic biologist! And I think a big problem is physically executing biology programs.

I've been working on building a programming method for biology labs. Basically, it is a dynamic execution environment using lua that can have full rewind-ability (for complete execution tracing) and pausing - you can execute some code then wait a week or so to continue execution. The idea is you can have a dynamic environment for executing biology experiments where the route changes on the basis of outcomes - something I haven't really seen anywhere else. Then I focused a bit on the pedagogy of LLMs so that you can ask an LLM to generate a protocol, and then when you execute it and get unexpected results, it can automatically debug its own protocol using a code sandbox.

It all sounds decent in theory but the difference is I actually implemented it and ran a real biology experiment with it (albeit a simple one that I knew wouldn't work)

Demo here: https://github.com/koeng101/autodemo (probably watch the video)

I'm working on a new Event Sourcing database that elevates the WAL into a first class application concept like a message queue. So instead of standing up a postgresql instance and a kafka instance and a bunch of custom event sourcing plumbing, you stand up this database and publish all your application events as messages. For the database part you just define the mappings from event to table row and you get read mode…

Interesting. Sounds like a similar premise to Supabase Realtime. I'll keep an eye out.

I'm working on pure.md[1], which lets your scripts, APIs, apps, agents, etc reliably access web content in markdown format. Simply prefix any URL with `pure.md/` and you get the unblocked markdown content of that webpage. It avoids bot detection and renders JavaScript-heavy websites, and can convert HTML, PDFs, images, and more into pure markdown. pure.md acts as a global caching layer between LLMs and web content. I…

Thanks for sharing. I was planning on building something like this in April after hitting too many issues with Jina and Tavily but it looks like you've already done the hard work!

I'm thinking of writing an app to manage ticketing and events in Europe. There's Eventbrite but it mostly for larger cities instead of mid-sized ones. I think there could be a niche for cheaper alternatives especially since student societies get charged like 2.50 euros on top of a 10 euro ticket.

Also, writing a Masters thesis on area-level and individual-level predictors of breast cancer... so a lot of applied ML.

Neat! How does this differ from KSQL?
