Sharing my experience with vibecoding

Hey everyone in the past 5 months I have used many Ai IDEs , many websites and many services to vibecode some apps/programs with different levels of difficulty .

For example I have used tools like Google-antigravity , Cursor , Gemini Cli , Claude Code , Replit , Kimi Code and more . What I noticed is that the cli based Agents and their tools perform way better than the same ones integrated inside IDEs . Also I noticed a way smaller token consumption on cli based tools due to their straightforward implementation .

For example Google Antigravity builds a plan before implementing things and consumes more tokens for that. For me that is not worth it at all .

Now in the project part , I have built from simple Android / IOS apps like a calendar app and a widget app to a fully deployed AI IDE with 80+ thousand lines of code with typescript , swift , tailwind css etc . Yes I built it with electron + vite which some may say it is bad for performance and ram consumption because it is chromium based but even though I put so much effort into bringing down that ram to the current state of 450mb on idle now it has performance issues .

What I want to say is that for a project that complex the Ai agents I used from Claude opus 4.6 thinking high to Gemini 3 pro high and codex models all failed in some ways . Some left dead code behind , some left unused imports , some left unimplemented functionality and much more .

TLDR , the AI world is constantly improving with breakthroughs like the latest Glm-5 , Claude opus 4.6 and Gemini 3.1 pro but still those models do not have the ability to read a whole complex codebase and remember everything in it to implement 100% quality and functional code . Tools like eslint that I used helped but still it failed. Those Agents in my opinion need a way higher context window and increase their SWE scores .

That was my personal opinion guys , this is not a self promotion post or anything !

What is your opinion about the current tools and Agents we currently have ?
