What developer tool should we build next?

We built HavenTools around a simple idea: everyday developer tasks shouldn't require sending your data to another server.

HavenTools is a collection of fast, privacy-first tools that run directly in your browser — including formatting, validation, conversion, and other developer utilities.

We're starting with a focused toolkit and want to keep expanding based on what developers actually need.

What developer tool or utility would you love to see added next?

I'd genuinely love to hear what would save you time in your day-to-day workflow.
