Searching for free programming tool.

Hi, our company has developped STM32F103 Cortex M3 applications which are flashed into our systems in the production facility with a old free RFlasher7 (JTAG/SWD) tool. We now have developped a new system using the STM32G041C8T6 Cortex M0 device which is not part of the old free RFlasher7 tool. We can use the keil uVision IDE but I wonder if there is some other free tool to flash this new microcontroller program into the corresponding devices.
