Show HN: DevUtils.app – Developer Utilities for macOS
The JSON formatter/validator alone would make this worth the money to me.  A YAML formatter/validator could also be very useful.  But they do have to be rock-solid and able to handle large inputs (think gigabyte scale files), otherwise they’re just toys like all the other local apps I’ve found in this space.The other features are not currently as useful, but I’m happy to support them as well.I hate to say it, but doing this on the App Store with IAP to cover the upgrade from the demo version to the full version would be a viable way to distribute your app and handle the back-end payments.
