Browser settings

The Neo4j Browser defaults for all settings can be adjusted at any time in Neo4j Browser and globally. As briefly introduced in Settings, available settings can be adjusted in the Settings drawer in the sidebar.

Table 1. Available Browser settings
Browser Setting	Default value	Description
`maxVizNodes`	`1000`	The maximum number of nodes to render in the graph visualization.
`maxNewNeighbours`	`100`	The maximum number of neighbours for a node.
`recordLimit`	`1000`	The maximum number of results to fetch per frame.
`maxHistory`	`30`	The maximum number of recently executed queries kept in Browser. When reached, old entries get retired. The command history is persisted across Browser restarts.

`enableLinting`	`false`	Show errors and warnings in the query editor.
`crashReports`	`true`	Enable/disable crash report collection.
`usageTracking`	`true`	Allow product usage statistics to be sent.
`theme`	`system`	Neo4j Browser UI theme. Possible values: `light`, `dark`, and `system`.

Adjust settings globally

To change the configuration settings for all users of Neo4j Browser, modify the neo4j.conf file, or if using Neo4j Desktop, navigate to the instance which settings you want to update and select Settings from the more […] menu. Note that you need to provide your own application to access the neo4j.conf file.

For example, to change the maxFrames from its default of 50 to 10 and the theme to dark, add the following line to neo4j.conf:

browser.post_connect_cmd=config {maxFrames:10, theme: "dark"}

This changes the maxFrames from its default of 50 to 10 and then restarts Neo4j.

Table 2. Global Browser settings

`browser.allow_outgoing_connections` Deprecated	`true`	Configure the policy for outgoing Neo4j Browser connections. This should be managed by using `dbms.security.http_static_content_security_policy_header` instead. See Operations Manual → Security settings for more information.
`browser.credential_timeout`	`0s`	Configure the Neo4j Browser to time out logged-in users after this idle period. Setting this to `0` indicates no limit. Valid units are `ns`, `μs`, `ms`, `s`, `m`, `h`, and `d`; default unit is `s`).
