ServiceNow App Engine vs. Appian

ServiceNow App Engine is a development platform for building, extending, and governing custom work on the ServiceNow AI Platform. Developers use it to create new tables, extend out-of-the-box workflows, and build full applications. Business teams use it to replace the spreadsheets, email chains, and standalone tools that often run core processes. Most custom development on ServiceNow doesn’t start from a blank slate. Teams add fields and tables to existing processes, change how a request routes through an approval, or add logic to a workflow the platform already runs.

Appian is an enterprise AI process automation platform that helps organizations orchestrate, automate, and transform complex end-to-end workflows. The platform connects AI models, enterprise systems, data sources, digital workers, and human teams to accelerate operations, reduce operational costs, and manage enterprise risk. Built primarily for large enterprises and government entities, Appian supports mission-critical applications across core business functions like financial services, insurance, pharmaceuticals, and public sector operations.
