Yosys, the underlying compiler of ice studio, also targets the much bigger ECP5 FPGA, also by Lattice, which is called Project Trellis: https://github.com/YosysHQ/prjtrellis

Yosys functions more like a software open source tool. So command line compiling. It also has a REPL. It is very quick compared to the commercial solutions. Especially around compile times which can take seconds instead of minutes. YMMV, but I think the consensus is that it's a lot more convenient to use.

In general the hardware toolchains feel very ancient compared to software toolchains.

Yosys / project Trellis and nextpnr are amazing - I've played with them using an IceSugar-Pro board (which despite its name has an ECP5-25 FPGA) - but there's also an experimental branch for Xilinx 7-series devices now - Project X-ray, with an even more experimental branch of that targetting the Kintex7-325 FPGA on one of the QMTech (AliExpress) boards. That's of particular interest since that FPGA is large / high-end enough not to be supported by the free version of Vivado!
