Tools

Most of what ends up here started as something I did by hand — a spreadsheet tab, a manual step in a project, a scratch calculation for a post. A tool graduates to this section once I’ve done the same task manually three times; it doesn’t have to involve any math.

They run entirely in your browser — there’s no backend on my end. If a tool needs to talk to an external service, say an API you’ve given it a key for, that request goes straight from your browser to that service, not through mine. Read the source if you don’t trust what it does; it’s a few hundred lines of TypeScript, not a black box.

New tools show up when I need one, not on a schedule.

GitHub Repo Risk Score

Paste a repo, get a first-pass risk score from license, commit activity, contributors and stars — with optional deeper checks for security advisories, bus factor and community health — before you tell a developer yes or no.
