Developer mode

Developer mode reveals the settings Myne keeps out of the way by default: the ones where you leave the path Myne vouches for, and the power-user tools most people never need. It is a switch in the About panel, it is set per vault on the device you set it on, and turning it back off hides those settings again without turning any of them off.

Prerequisites

• A vault open. Settings is only available once a vault is unlocked.

Turning it on

Open Settings from the gear in the bottom bar or with ⌘,, choose About in the left rail, and switch on Developer mode. It takes effect immediately — there is no restart and no confirmation step.

The setting is per device: switching it on here does not switch it on anywhere else, and each vault on this device decides separately. It is kept with the rest of this vault’s preferences, in the encrypted preferences file, which travels to the server like the rest of your vault and stays unreadable there. What “per device” means is that your choice here is the one that wins on this device, not that the value never leaves it: a backup carries it along, and a brand-new device that has never had an opinion starts from whatever the vault last held.

What it reveals

Turning it on adds a Developer section at the bottom of the settings rail, holding two panels:

• AI — Myne’s experimental AI features. AI is off until you opt in, and nothing is sent anywhere until you name a provider. See Where your AI runs.
• Network — the option to send Myne’s sync traffic through Tor. See Routing sync through Tor.

It also reveals two settings that stay in the panels where their topic lives, rather than moving into the Developer section:

• Vim keyboard mode, in the Editor panel. See Vim mode.
• Terminal access, in the Privacy panel — the door that lets the myne command on this machine read and change an unlocked vault. See The myne command-line client.

Those two keep their homes on purpose, so looking for a Vim setting still lands you in Editor and looking for terminal access still lands you in Privacy.

Turning it back off

Turning Developer mode off hides these settings. It does not turn any of them off. A terminal-access socket you enabled keeps serving, and a Vim keymap you enabled keeps running — the mode controls what Settings shows you, not what the app is doing.

So switch a feature off from its own control first, and then turn off Developer mode. If you turn the mode off while something behind it is still on, turn the mode back on to reach the control again.

Limits

Developer mode is a way of keeping advanced settings out of the way. It is not a security boundary, and this guide will not describe it as one. It changes what the settings rail, the settings search and the command palette offer you; it does not stop anything you have already enabled from running, and it is no barrier at all against software already running on your device.

What sits behind it is what Myne does not vouch for on your behalf: a model runtime or a remote provider you supply, a terminal process outside Myne, and a relay network nobody here operates. Each of those has its own limits, stated in its own article.
