Dogbolt is an online interactive decompiler explorer. A binary can be uploaded and the decompiled C-like output of multiple decompilers compared. The website collects all uploaded binaries, so be wary of which files to upload. The big advantage of the website is having so many available decompilers (angr, Binary Ninja, Boomerang, Ghidra, IDA Pro, REC Studio, Reko, RetDec, Snowman). A downside is that no alterations to the decompilation are possible, for example, to provide function signatures.
