24 alternatives to An MMORPG where you control your characters with an API

Hi, I’ve been working on Artifacts for the past 2 years, and it’s now ready to try. It’s a sandbox MMORPG where every action is done through a REST API. Instead of clicking to move, fight, gather, craft, or trade, you write code to control your characters. If you have any questions, comments, or feedback, I’d be happy to hear them.

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Hi, I've been developing an HTML5 MMORPG game where people can submit code to play a game, like collect items, destroy defense towers or kill monsters, etc.. I've been working on this for over 1.5 yrs (all my spare time) and now it's ready for preview, does anyone want to try it out? It's mostly opensource (and the rest will be opensource sooner or later) Please access it with PC, it's an HTML5 game: https://bytelegend.com/ I really want it to expand to more languages, but right now I've only finished Java part. I wonder if anyone can help me with other languages. Besides, I'm…

    Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

    I made a game (https://polyfight.io/) which revolves around a player (a tank) leveling up and upgrading by killing shapes and other tanks (partially inspired by https://diep.io). It has a bunch of features, a vast number of tanks, an inbuilt chatting system, clans to make teams with your friends, a colour scheme maker, controllable sandboxes which can be public or private, a last man standing gamemode, and an inbuilt 1v1 system with its own ELO rankings and a global leaderboard. The game has a few players right now, and I'd hope to spread the joy players have with…

    I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…

    Hi I've created a text-based RPG game in which you can experience different adventures and play interesting characters while the AI acts as a real time DM/story teller. There are multiple ways to interact with AI: 1) Input free will move 2) Input default move (affects resources) 3) Post a question to DM Also one more cool feature is that you can create your own adventure via simple form. Add scenes, add characters and make it public so other players are able to test it. I also plan to have 'competetive' side where players will pay some small fee to creators in crypto depending on…

    hi all, I've always wanted to make my own game, but couldn't afford a thousand-dollar adobe (flash+photoshop) license. I'm not a talented programmer, have no degree in CS. But I understand some elements of design. So I got me a copy of ImpactJS, and after about 5 months of steep learning curve (at least for me), I managed to come up with a game. I also integrated it with a highscore and badge system, similar to what you get at Kongregate. You need to login with Google/OpenID to earn badges/scores. link is: http://www.hotbazooka.com/privatejoe hope to hear some feedback/questions from you guys!

    Dear Hacker News, I'm kindly asking for your participation in the open beta for my AI-managed mini-games website. Thank you in advance! For a limited time window, I'm setting the all-free feature flag to true. I hope you have a lot of fun exploring the AI's sense for games! Here and there, I tweaked it to help with visual consistency. I would be deeply grateful if you opted into analytics. $2,300 in API tokens... Cheers!

    Hello everyone! I've finally finished my latest side project - a RPG game made in Blazor. It started as a small project to learn some Blazor (I'm .NET dev but kept mainly to backend and ASP.NET). I had such a good time coding it that at some point I decided to make a full featured game out of it. I might've have bitten off more that I could chew as RPGs have so many systems and elements but overall I think it worked out well, especially for a single person project. I want to hop on the next project soon so any comments/questions/tips than can make me better really appreciated!

    Hello guys, I'm glad to present to you PlayAlgoShip, a web-based game where you solve fun algorithmic puzzles. The rules are simple, you need to find the correct algorithm that makes the ship collect all stars. If you succeed, you will unlock the next level! There are also live statistics like how many players are currently playing on your current level (you are not alone struggling!), the finish rate of the level, and how many players liked/disliked it. It's 100% free, I hope you will enjoy the experience!

    Hey HN, I made https://linkians.com which is a game where all the action and state is contained in the url. The game involves taking care of little pets (emojis) that live in your url bar. Kind of like tamagotchi or sims. Feed them, play with them, and watch out for enemies! There's no server, just emojis in the url and client-side logic. Any linkians url using the supported emojis is a valid game state so you can save your game, or type out your own url and send it to a friend. I'd appreciate any feedback.

    You speak to the Oracle of Aion, an ancient entity with the power to affect the dungeon. If your wish is worthy, he may grant it, and the dungeon remember your wish forevermore. The changes will be visible for all players, forever. Play now in the browser! Free and no registration. Disclaimers: I singlehandedly made this game, it is in a crude state, the oracle works 50% of the time. Also, since your wishes turn into code automatically via AI, and literally anyone can wish whatever he wants, dont expect a polished experience. However, nothing like it exists and its free, enjoy the chaos!…

    Hi HN, I’ve been working on DungeonLoot a passion project that’s not the usual SaaS or AI tool. The goal is simple: bring more loot to gamers, and help game developers get discovered in the process. Not the trendiest idea, but sometimes we just do what we like. Link: https://www.dungeonloot.com/ Let me know what you think.

    Hey everyone, I built this project because I always wanted to try playing D&D but couldn’t find a group of friends or a DM to play with. It’s still early stages and not meant to be a complete replacement for real DMs or IRL sessions, but it’s a good way to dip your toes into DnD or to play on your phone between your IRL sessions. I tried playing D&D with ChatGPT but the overall experience was lacking, so I built this site & Discord bot that has a character sheet tool, better memory management, support for multiplayer, and automatic tracking for things like spells, HP, and encounters. Try it…

    Hi everyone! Want to share something I'm working on. Here is the brief description: From a single text prompt, craft dynamic worlds (both fictional and real-life, of any kind) filled with interacting NPCs pursuing goals, and control (human-in-the-loop) their behaviour and world state in real-time. Text-to-image to visualise every single step of change in the world's and NPC's state. My main goal was to check if it's possible to use LLMs (GPT-4 currently) to make characters interact with each other but in the end, it ended up with a neat little app where users can interfere with NPC's (and…
