Avonni offers two no-code tools for building custom Salesforce UIs. Here's how to pick the right one for each project — and stop building workarounds.

Note: This isn't a comparison of which tool is better. Dynamic Components and Flow Screen Components are designed to work together. This article explains what each one is for, so you pick the right one per project — and stop building workarounds.

You need a custom UI on a record page. Maybe a mission-control dashboard for your sales ops team. Maybe a redesigned related list with filters and row actions. Maybe a panel that shows KPIs next to a Kanban. You already know Flow Builder. You've seen Avonni Flow Screen Components. So you do what almost every Salesforce admin we talk to does first: you build a Screen Flow, drag everything onto a single screen, and embed it on the Lightning page.
Please don't. It's the most expensive wrong turn we see in Salesforce UI work, and it's the reason I'm writing this.
I want to be direct about what's happening here. Flow Builder is process automation software. It was built to move a user through steps, branch on logic, and write data at the end. When you use it as a layout engine for a record page, you are fighting its architecture on every dimension that matters:
And the Avonni Flow Screen Components sitting inside that Flow, however nice they look, cannot rescue any of it. They inherit Flow's rendering model. They were never meant to turn Flow into a page-builder. That is not their job.
The tool that actually replaces the custom LWC you were hoping to avoid writing is a different Avonni product. It's called Dynamic Components. And most of the customers asking me "why would I need this if I already have your Flow components?" have never opened it

This is the product that stands in for a custom LWC. If your instinct is "I wish I could just write an LWC for this," Dynamic Components is the no-code answer.
These are for work that has a beginning, a middle, and an end. A 5-step client onboarding wizard. A multi-screen case intake form. A bulk edit where users select, change, and confirm before saving.
Try to turn one into the other and you get neither.
Every time someone asks me which to use, it comes down to one question:
Where are you building?

They don't conflict, and most of our customers end up with both within the first month.
Still unsure? Run through these four checks:
When your answers keep pointing the same way, you have your tool.
"I want to redesign the related lists on my Account record page."→ Dynamic Components. Always visible, always reactive. Build a Data Table with search, filters, conditional formatting, and row actions.
"I need a 5-step wizard for onboarding new clients."→ Flow Screen Components. Sequential steps, conditional logic, data creation at the end. Flow Builder orchestrates. Avonni makes each screen look good.
"I want a mission-control dashboard on my record page."→ Dynamic Components. Compose metrics, charts, and a data table into a reactive layout that loads with the page. No Flow involved.
"I need a bulk data editing screen where users select, edit, and confirm before saving."→ Flow Screen Components. The word "confirm" is the tell. This is a process with a write operation at the end.
"I want a page with charts and a Kanban, plus buttons that launch processes."→ Both. This is the pattern most mature Avonni orgs land on.

Here's how both tools work together on a real page:
Dynamic Components for what users see. Flow Screen Components for what users do
I can tell you exactly what happens, because we watch it happen every week.

Someone builds a single-screen Flow as a record page. It works at first. Then things start to drift:
[OPTIONAL IMAGE 6 — DEGRADATION TIMELINE: Horizontal strip showing Month 1 → Month 3 → Month 5 → Month 6 → Month 8, each with a small icon showing the degradation. Net-new illustration, optional but worth commissioning.]
At that point the team starts asking us whether Avonni can "fix" their Flow. We can't fix the architecture underneath it. They picked the wrong tool, and the cost of switching grows with every week they wait.
Ask yourself these four questions:
1. Am I building on a Lightning page or inside a Flow?
Lightning page → Dynamic Components
Inside a Flow → Flow Screen Components
2. Does the user go through steps?
Yes, sequential steps → Flow Screen Components
No, everything at once → Dynamic Components
3. Is the goal to display data or collect it?
Display and interact → Dynamic Components
Collect and process → Flow Screen Components
4. Do I need a custom page layout AND a guided process?
Yes → Use both

Most Avonni users end up installing both packages.
Together, they cover every no-code UI use case in Salesforce.
