SilverBullet currently supports two modes for its client:

1. _Online mode_ (the default): keeps all content on the server
2. _Synced mode_ (offline capable): syncs all content to the client

You can toggle between these two modes by clicking the 🔄 button in the top bar.

You can switch modes at any time, so try them both to decide what works best for you.

## Online mode
In online mode, all content in your space is kept on the server, and a lot of the heavy lifting (such as indexing of pages) happens on the server.

Advantages:
* **Keeps content on the server**: this mode not synchronize all your content to your client (browser), making this a better fit for large spaces.
* **Lighter-weight** in terms of memory and CPU use of the client

Disadvantages:
* **Requires a working network connection** to the server.
* **Higher latency**, since more interactions require calls to the server, this may be notable e.g. when completing page names.

## Synced mode
In this mode, all content is synchronized to the client, and all processing happens there. The server effectively acts as  “dumb data store.” All SilverBullet functionality is available even when there is no network connection available.

Advantages:
* **100% offline capable**: disconnect your client from the network, shutdown the server, everything still works. Changes synchronize automatically once a network connection is re-established.
* **Lower latency**: all actions are performed locally in the client, which in most cases will be faster

Disadvantages:
* **Synchronizes all content onto your client**: using disk space and an initially large bulk of network traffic to download everything.
