What are you working on? Any new ideas that you're thinking about?

I bought a 150 year old house. Need I say more?

Working on v2 of our n+1-proof/reactive TypeScript ORM, Joist (https://joist-orm.io/), that moves to using the new-ish postgres.js driver (instead of knex/node-pg), so that we can leverage postgres.js's statement pipelining within transactions.

I'm anticipating a really sweet perf increase (as shown by some proof-of-concepts), but now that everything is actually working on the v2 branch, I'm putting together benchmarks that show the benefit in practice.

Love to have anyone poke around/ask questions/hang out on discord.

I built a reverse proxy similar to Cloudflare Tunnels that can be self-hosted:

https://tunlr.dev

This came about because of how awkward Cloudflare Tunnels is to use in a development environment.

I'd love something like this, however the pricing isn't clear. It looks like I have to pay for a $100/yr server license and self-host it?

If you want to use your own domain and certificates, yes. Otherwise you can use the Cloud version for free with a dynamic hostname, or you can contact us for a static hostname setup.

I built a free and open-source invoice generator with a live PDF preview that runs in your browser.

It supports multiple currencies, VAT tax deductions, and lets you download PDFs in multiple languages (English and Polish for now, with more coming soon). You can also share your invoice by clicking “Generate a link to invoice” button.

Try it out: https://easyinvoicepdf.com/

Check it out on GitHub as well:

Would love to hear your feedback =)

I’m working on a live voice chat for settling rule disputes during tabletop gaming. It uses OpenAI’s realtime API to allow anyone to call in a “ref”, trained on the rules of the games, to answer questions about the rules.

How do you feed rules to OpenAI?

This is probably one of the most redundant project out there, but a RSS reader app designed with Tauri, Sveltekit, Tailwind. I wanted to build this to stay in sync with product development as I don't get to do this a lot in my day-to-day job. I also want to build a game, but it is so much effort. I do wish to pursue it in near future.

I just launched the beta for Table Slayer. It lets you build animated maps for in person RPG games (DnD, Pathfinder...etc) where you have a digital table top. It's built on Svelte + Turso + websockets.

The video here best shows it off. The source is available and free to use for non-compete, personal use.

Mostly a labor of love. I don't expect there to be a super large audience for this one, it was just something I needed myself.

I'm expanding my website Bingeclock (online since 2014) into mobile. Both the iOS and Android apps were approved for open testing last week, so I'm very happy about that!

I've been working on an alternative to JSON called XferLang, and along with that a "CLI construction kit" that will let the user create a CLI for interacting with RESTful APIs (and, eventually, more).

Seems interesting tough more complicated. In json you can't have multi line strings? Does your format supports it?

I’m building an AI chatbot for businesses to handle sales and lead qualification via WhatsApp and Telegram — https://ziriusai.xyz/en

Doing it completely solo — built the product, run the ads, do the outreach, everything. Struggling with sales now. Thinking of narrowing focus and solving a more specific pain point.

Curious if anyone else here is grinding through early-stage B2B SaaS — would love to hear how you're tackling this.
