via “expression language for dynamic data transformation and parameter binding”
Fair-code workflow automation platform with native AI capabilities. Combine visual building with custom code, self-host or cloud, 400+ integrations.
Unique: Provides a sandboxed JavaScript expression evaluator with access to execution context through a scoped variable system ($node, $env, $workflow) rather than exposing raw Node.js globals, enabling safe dynamic parameter binding without security risks. Includes an expression editor with autocomplete based on available context variables and real-time validation.
vs others: More powerful than Zapier's static field mapping with support for complex transformations, but safer than Integromat's full JavaScript execution by running in an isolated context without access to require() or async operations
