LLMs make small, personally useful software projects worth building
After finding existing domain lookup sites slow and cluttered, the writer used Claude Code to build and deploy a replacement in about an hour. It illustrates how coding agents can change the effort threshold for small tools.
- What
- An engineer built heade.rs, a personal domain lookup tool, with Claude Code in about an hour.
- How
- The tool shows DNS and registration records, live latency, email configuration, and HTTPS details; the author says it costs less than a cup of coffee monthly to run.
- Why it matters
- LLMs can lower the effort needed to build useful, polished tools for narrow personal needs, even when they are not products for a broad audience.
