You may be wondering, how we can give away such a great tool at no charge? We get our revenue from

Cost sharing contributions from our microcontroller partners.

These partners believe in the value of providing a commercial quality tool at no-cost to their customers. The alternative is for them to invest in creating a tool of their own which will not have all of the rich features of TrueSTUDIO.

Selling licenses to unlock TrueSTUDIO Pro features

Our subscription model lets you upgrade to Pro for a low annual fee. You can read more about the Pro upgrade here. The upgrade unlocks all of the Pro features along with tech support and updates. And the annual subscription fee is likely significantly less than what you would pay for annual support and maintenance alone on a license from that three letter workbench company.
