Enhance subscriptions with Merge and Script

Advanced featuresUpdated 2026-06-28

Merge and Script are signature Clash Verge features: they modify the final config as an overlay, so your customizations survive subscription updates.

The two enhancement methods

Merge (use this first): declarative YAML merging. prepend-rules / append-rules insert rules at the head or tail of the rule list, and same-named fields override the subscription values — covering rules, DNS tweaks, port changes, and most other needs.

Script: programmatic modification in JavaScript. Export a main(config) function and transform the config object freely — bulk-rename nodes, add or remove proxy groups conditionally, any complex logic.

Where to find them

1. Open the Profiles page and locate the Merge and Script cards in the global extension area.
2. Right-click a card and choose “Open File” to edit.
3. Saving regenerates the config immediately; right-click the active subscription → “Open File” to inspect the merged result.
