Tools that respect
your tab.
Toolkit is a working desk for software engineers — a single site that gathers the daily utilities, the interactive models, and the long-form reading that keep the day moving.
The principle
Everything on Toolkit runs in your browser. Nothing you paste, type, or configure is sent to a server you cannot see. No account, no key, no pixel. If a feature requires a round trip, we'll say so — and it'll still be optional.
What's here
70 tools across seven categories, 38 long-form guides, 16 handbook entries, and a set of interactive simulators for the systems behind the tools. The shape of it is deliberately reference-like: browseable, linkable, and meant to be re-visited.
Who it is for
Working engineers — the ones who format JSON at 3am, who reach for a regex tester when a log line won't parse, who argue about consistent hashing on whiteboards. Less opinion than a blog, less weight than a textbook, less noise than a Google search.
Who makes it
Toolkit is open source. Issues, suggestions, and corrections are welcome — and the parts you find useful are the parts that will keep existing.
