People may be taking your comment as general knee-jerk electron hate but it really is something to consider.

If you're sending requests that can return very long json responses, Insomnia can lock up and force you to restart it.

Paw is a pretty good native alternative but it's macOS only, doesn't have a free tier beyond a short trial period, and has some UI quirks that made me ultimately go back to Insomnia despite the electron borne downsides.

If Insomnia could offload the request response parsing/formatting to a WebAssembly module it would be perfect.
