Inspiration

I got the idea for Base Coder after seeing a Reddit post where someone partially recreated a Codex-style experience on their own PC. That made me interested in seeing how far I could take local AI and whether I could create a coding assistant that works without constantly using paid credits or tokens.

What it does

Base Coder is a locally hosted coding assistant that can answer questions, generate code, create projects, edit existing files, and test what it builds. It uses the computer’s RAM and local AI models it downloads instead of requiring paid API usage for every prompt.

How we built it

I built Base Coder with the help of Codex and GPT-5.6, mainly using the Sol model when making it.

Challenges we ran into

This was my first project of this size, and I do not have a "large" amount of traditional coding experience. There were many errors and bugs but I think all where resolved in the end. Sometimes when I fixed one problem it created another (ESPECIALLY WITH THE CREATION OF STUFF), so a large part of the project involved testing and revising features repeatedly.

Accomplishments that we're proud of

I am proud that I was able to complete a working demonstration video and concept for such a large first project.

What we learned

I learned a lot about local AI models, computer hardware limitations, and how important testing is when AI is allowed to create or edit files.

What's next for Base Coder

The next steps are to fix remaining bugs, improve consistency, support more local models, improve project testing, and make it easier for beginners to use. I would also like to improve performance and eventually explore better mobile or cross-device support.
