AI vibe coder that's engineering real apps, not just outputting code

Hey builders,

I started the vibe coding journey being amazed at how fast and efficient it was to build new apps from scratch.

Experimenting and building the past few months have taught me that these agents are incredible tools, but as it stands they are still just tools. This means the user behind them bears the responsibility for the performance and quality of output.

Witnessing how engineers at startups and big tech who are probably in the top 5-10% of users work, it's clear that there's a huge gap between top performers and everyone else, and it mostly boiled down to experience and the toolkit.

Web platforms available now for building apps with AI and no code are still leagues behind what top engineers in industry are using: Claude Code in terminal customized with home-brewed subagents, skills, hooks, etc. Beyond coding prototypes, they used these tools to handle integrations, security, design, CI/CD, and more. They have boilerplates and tech stacks that they're familiar with and can reuse for multiple projects.

Right now these workflows are locked behind expertise and setup time that most people don't have.

That became the goal for my next project: experiment with the best possible setup and bring it to a platform anyone can actually use. That meant building a custom agent from scratch and developing infrastructure that handles the things AI typically gets stuck on like backend, DB, auth, and key integrations.

Subterranean is the product of trying to achieve our optimized setup and making it available on the web, making it easy to use the best workflows by just signing up and typing in that first prompt.
