Vibe Coder, Roblox AI tool that ppl pay 2k$/m for - Sell Project

Sale Offer - Vibe Coder

I am offering to sell the full copyright and ownership rights to the Roblox plugin tool Vibe Coder (which can be downloaded using the https://rbxvibecoder.com website), including all source code for plugin client, source code for plugin server, source code for plugin's website, social media accounts, brand logos and the rbxvibecoder.com domain.

What is Vibe Coder?

Vibe Coder is an Roblox Studio plugin (.rbxmx file), that utilizes Large Language Models to write all kinds of Roblox Studio Lua scripts. The user can develop an game without the coding knowledge, he can tell AI to write scripts for him, and the model will do that for him (using an authorial AI connection system, that also makes the model analyze the problem more deeply, and makes him able to edit user's scripts). The whole LLM interaction is being done in an chat style inside the plugin's window in the Roblox Studio app. For better user experience, when user sends an message to AI, Vibe Coder is also giving the model more context, such as the whole project hierarchy summary, earlier chat history with the user and the current state of the user selected script.

Vibe Coder plugin supports a wide range of popular LLMs including: Gemini 2.5 Flash, Gemini 2.0 Flash, Gemini 2.5 Pro, GPT-4.1, GPT-4o, GPT-5, Claude-4 Sonnet and Claude-3 Sonnet, however, user needs to input their own API keys for most of the models - expect for the Gemini Flash models, because as these models are free of charge.

The plugin is also paid. It has an free plan, but it was made for the users to just try out the plugin (they are limited to 5 messages a day, and only one model). The pro plan unlocks all features, the payment is being done trough an Roblox game pass, because i can't implement an payment system like Stripe. ~3000 people have downloaded the Vibe Coder plugin.

Earnings

Right now, the product makes people pay ~$2250USD/month (calculated from Robux USD price, purchases made from last 30 days). However, because of the product's payment method, Roblox'es tax makes it earn only ~$480USD/month (127109 Robux a month). But changing the payment method to Stripe could make you earn the $2k.

Also there is a lot of potential to earn more, for example you can:

- Improve the promotion. The product currently lacks advertisement - the social media accounts aren't active, there are no influencer collaborations going on. By reaching more audience, you can earn much much more.

- Improve the product. Community is begging for new features for Vibe Coder. Some of them are: Allow users select multiple scripts and let AI edit them, Add new models such as GPT-5, Let model edit not only scripts, but your entire project - changing the project's hierarchy, editing object's values. These features would make Vibe Coder tech-breaking and viral.

- Add new paywalls.

Source Code

The Vibe Coder plugin client was written in Luau, there are also two servers written in Deno. The first one is the website, the second one is the gg system. The code is clean, well-written and ready for future developement, if you would need help with understating the project structure, i can help you.

Also, the .rbxmx that is available in the public is being obfuscated using https://wearedevs.net/obfuscator (Lunau obfuscator)
