The decision tree starts with the use case, not the tool. Pick the lowest-code tool that meets the requirement; reach for Pro Code only when the declarative tools genuinely fall short.
- Identify the use case
Automation? UI? Reporting? Each use case maps to a primary Low Code tool.
- Try Flow Builder for automation
Record-triggered, screen, scheduled, or platform-event flows handle the vast majority of automation needs.
- Try Lightning App Builder for UI
Standard components plus selective custom LWCs cover most UI requirements.
- Try OmniStudio for industry workflows
Complex multi-step user journeys in Industries Cloud belong in OmniScripts.
- Reach for Apex when needed
Performance-critical batch, multi-system orchestration, or logic exceeding declarative capability. Apex extends declarative tools, not replaces them.
- Document the choice
Note why each piece is Low Code or Pro Code. Future admins inheriting the work need to understand the rationale.
- Pushing too much complexity into Low Code produces unreadable flows. Switch to Apex when the flow exceeds 50 elements or has deeply nested logic.
- Low Code tools share Apex governor limits. Bad flow design fails the same way bad Apex does.
- Mixing tools without clear rationale creates maintenance overhead. Document the choices.
- Skill investments matter. Admins comfortable with Flow Builder are more productive than developers writing the same logic in Apex.
