Questions
Is anything locked behind a paid plan today?
No. Everything MCUHex does right now — SWD flashing, live variable monitoring from a .elf or .out, table and chart views, CSV export — is on the free plan and stays there. The paid columns describe work that is not built yet.
What does "per developer" mean?
One seat per engineer, billed monthly. Boards and debug probes are not counted — one engineer can work across as many targets as they like on a single seat.
When can I actually pay for Pro?
When enough people ask for it. Joining the early-access list is what decides which of the Pro features gets built first, and you are not charged anything by signing up.
Which targets does MCUHex support?
ARM Cortex-M parts over SWD, with STM32 as the best-tested family. JTAG-only devices are not supported.
