HolySN

ServiceNow developer toolkit: command palette, update set guards, dark mode, code search, a real code editor and an AI assistant.

HolySN is a toolkit for people who build on ServiceNow every day. It works inside your instance, through your own session, and puts the tools the platform makes you leave the page for right where you are working. COMMAND PALETTE • One prompt for navigation, list queries, scripts and toggles • List switches to filter, group and order results as you type • Your own custom commands, with variables filled from the page you are on UPDATE SETS, SAFELY • Guards on every save so changes never land in the Default update set by accident • Auto-Insert, and checks that read a set before you ship it • Deploy to your other instances, with production clearly marked A REAL CODE EDITOR • A full code editor in place of plain script text areas, aware of ServiceNow APIs • Background scripts without leaving the page • Wildcards: short triggers that expand into full snippets in any script field • A personal library of saved scripts you can share with colleagues • Edit any script field in VS Code while your session stays in the browser FIND AND UNDERSTAND • Code search across every script field on the instance, including the ones the built-in search skips • Table inspector: everything attached to a table, read through its ancestry, exportable as XML • Compare two records, or the same record on two instances, with a line diff • Read flows from their own tables, and see what breaks if you change a catalog variable • Every attachment of a record in one place, plus the version history WORK MORE COMFORTABLY • Dark mode that recolours the platform's own design tokens instead of inverting the page, across Next Experience, classic forms and lists, and Service Portal • Themes in your own colours • Records as tabs inside the instance, with split view • Tell your instances apart at a glance AI ASSISTANT (Pro) • A conversation that already knows the record, table and update set you are on • Four permissions, all off by default: nothing touches your instance until you allow it PRO TOOLS • Form rewind: the form as it was after any earlier save, with who changed each field • Script blame: who wrote each line of a script, when, and in which update set • Collision radar: see when someone else is changing the same record in another update set • Record a click path once, replay it later, and turn it into an ATF test PLANS The command palette, update set tools, dark mode and the panel are free. Plus adds everyday paid tools and more room for profiles, scripts and wildcards. Pro adds the AI assistant and the history tools.
