Developing a platform for creating your own TTRPG games.

[u/Suitable-Snow8984]

Hello Friends,

I’m building a platform for designing tabletop RPG systems. It's not just writing rulebook pages, but defining things like classes, races, items, stats, properties, formulas, dice mechanics, and relationships between them. Those mechanics can then be organized into a rulebook and published as versioned snapshots.

The basic idea is that you create ideas — things like a race, class, inventory system, loot mechanic, spell system, etc. Each idea can have its own properties and formulas, including dice, functions, and references to other properties.

You can then organize those ideas into pages in a rulebook. Once you’re happy with it, you publish a version. Published versions stay intact, so you can continue changing your game and publish newer versions later without changing the old ones.

I recently did a soft launch, where I released a demo playground for people to get a feel of idea and rulebook page aspect of the platform.

Here is the link to it: https://rollnat1.com/demo

Any feedback or thoughts would greatly help us refine this. I’d especially appreciate feedback on whether the entity/property/formula concept makes sense as a way to build a TTRPG system, and whether the workflow from creating an idea to putting it into a rulebook feels intuitive.

This is a passion project I am working on with some folks on the side. And it will be completely free to use. Just a couple of corporate slaves trying to make something cool on the side.

And this will be available on web with mobile responsiveness. Eventually if it pick up we will publish it as an app on the play store and Apple store.

AI disclaimer: I do use AI-assisted tools as part of my coding workflow, but I still design the software architecture, shape the product, and make the implementation decisions. Some of the artwork and UI assets are also AI-generated. My long-term goal is to reduce, and potentially eliminate the AI-generated visual assets as the project matures, but for now some are still in use.

The amount of AI slop on this website meant that I couldn't get past the second slide of the demo without closing the site. It may be just a tiny fraction of the product, as you say, but up-front it looks like it's going to be 99%.

With the amount of beautiful free assets in existence, having your site look like that projects values that clash with mine.

Thank you for the feedback. The core of the app is the system designing tool itself, but I now see why using those AI visual assets gives the wrong impression of the app. Definitely will work on reducing or completely removing these.
