nxnative tools
Four small helpers that run entirely in your browser: nothing you type is uploaded, and no keys or game files are ever needed here.

Device checker
Pick your iPhone, iPad or Mac and see whether it meets the rule the nxnative project states.
Disk-space calculator
Enter a game's size and get the free space the project recommends for a build.
env.txt generator
Choose settings and get the lines for the env.txt file, with where the file goes on iPhone and Mac.
Command builder
Choose options and get the build_ipa_from_nsp.py command, with the combinations the script rejects flagged.
These tools only restate what the official nxnative repository documents (commit bfc70881). When the project changes, check the official README. Related reading: requirements and the build guide.
