TL What we do · File No. 05
The tools we build,
and the ones we buy
Two lists. First the free browser toolkits we build and give away, then the hardware and software we reach for on the bench. We look to integrate the best tools and technology into everything we do. Over the years we have found hardware and software we reach for every day, and this is that list. Many entries are entry level on purpose, so cost is less of a concern if you are just getting started. We keep it current as machines go out of production. For our software development stack, see our Stackshare.

01 Free toolkits
Instruments we built, yours to keep.
Every instrument in these toolkits is one HTML file that runs in your browser. No account, no server, nothing uploaded anywhere. Download it, open it from your own disk, and it keeps working whether or not we do.
