Best Salesforce Experience Cloud component libraries in 2026

Avonni is the best Salesforce Experience Cloud components option for teams seeking a subscription-based, no-code/low-code component library. For your 2026 shortlist, choose Salesforce standard components for built-in page content, Lightning base components for custom development, and Salesforce Lightning Design System for custom interface styling; Avonni is the packaged-library option compared below.

Why this matters

A component library, a developer toolkit, and a design system solve different problems. Treating them as interchangeable produces the wrong shortlist before you build a page.

For your 2026 decision, start with the work you need to avoid. Admins need configurable page elements; developers need reusable building blocks; design teams need consistent interaction patterns. A useful comparison separates those jobs instead of awarding every option the same generic badge.

The decisive question is not which library contains the most components. It is which approach lets your team deliver the required portal experience while retaining a clear path for permissions, maintenance, and future changes.

What makes the best Experience Cloud component library?

Use these criteria before comparing names:

• Builder fit: Confirm that the specific component works with your Experience Cloud site’s runtime and template. A Salesforce component is not automatically an Experience Builder component.
• Configuration depth: Separate changes an admin can make through properties from changes that require code. Test the exact variations your pages need.
• Data and access: Check how the component reads, displays, and updates Salesforce records under the intended user’s permissions.
• Interaction quality: Evaluate keyboard access, focus behavior, validation, empty states, and narrow-screen layouts in the finished page.
• Maintenance ownership: Identify who handles package updates, configuration changes, custom code, and regression testing after launch.

Choose the lowest-complexity approach that meets the actual requirement. A packaged component is useful when it replaces work you would otherwise build and maintain. A standard component wins when it already does the job.

Salesforce Experience Cloud components at a glance

This 2026 comparison ranks approaches by use case, not by an unsupported feature count. Only the first option is a third-party subscription component library; the others are native alternatives or development foundations.

The table is a decision tree. Start with built-in functionality, evaluate a packaged library when configuration falls short, and choose custom development when the requirement demands control that those approaches do not provide.

1. Avonni: best Experience Cloud library for low-code teams

Avonni sells subscription-based no-code/low-code UI components, including Experience Cloud components, distributed as AppExchange managed packages. Its stated audience includes Salesforce admins, developers, ISVs, and partners building Salesforce interfaces.

That makes the library a relevant shortlist entry when you want packaged components rather than a development framework. Evaluate it against a representative page requirement, not a general desire to make your portal look different.

Avonni pros:

• Offers a no-code/low-code component approach rather than requiring every interface element to start as custom code.
• Explicitly includes Experience Cloud components in its offering.
• Uses the AppExchange managed-package distribution model.
• Addresses both admin and developer audiences building Salesforce UIs.

Avonni cons:

• Introduces a subscription dependency into your component selection.
• Adds managed packages to the dependencies your team must govern and maintain.

Best for: Salesforce teams specifically seeking a packaged, subscription-based low-code UI library.

Before choosing, verify the exact component against your site runtime, data-access requirements, and interaction design. Also establish which changes remain configurable and which require developer involvement; the no-code/low-code category alone does not answer that question.

Verdict: Buy when the required component passes your site-specific acceptance tests; hold when the fit is unproven.

2. Salesforce standard components: best for built-in page needs

Salesforce standard Experience Builder components provide native building elements for Experience Cloud sites. The available components depend on the site’s template and runtime, so assess the options in the environment you will actually publish.

This is the right starting point when your requirements fit existing page content and interaction patterns. Keeping a suitable native component avoids adding a separate library solely to recreate behavior you already have.

Salesforce standard components pros:

• Provide a native starting point within Experience Builder.
• Let admins configure supported properties without writing a custom component.
• Avoid introducing a separate component-package vendor for requirements they already satisfy.

Salesforce standard components cons:

• Configuration is bounded by the properties and behavior Salesforce exposes.
• A component available in one site context is not proof of suitability in another.

Best for: Admin-led sites whose page requirements fit the native component set.

Test your difficult requirement first. If a page needs a particular interaction or record presentation, build that portion before polishing surrounding content. Discovering a fundamental limitation after assembling the whole page creates avoidable rework.

Verdict: Buy into the native approach when it meets the requirement; skip a replacement library for cosmetic differences alone.

3. Lightning base components: best for custom LWC development

Lightning base components are reusable Salesforce interface elements used when developing Lightning Web Components. Developers compose them into application-specific interfaces instead of implementing every control from scratch.

They are not a catalog of finished portal pages. To place a custom LWC in Experience Builder, a developer must configure its exposure and supported targets, then verify compatibility with the intended site context.

Lightning base components pros:

• Provide reusable building blocks for custom LWC interfaces.
• Let developers compose behavior around specific workflows and data requirements.
• Support a development approach where application code remains under your team’s control.

Lightning base components cons:

• Require development rather than only page-builder configuration.
• Leave the assembled component’s data access, state handling, and testing with your implementation team.
• Still require site-specific compatibility checks.

Best for: Teams with developer capacity and requirements that need custom behavior.

Draw the maintenance boundary before approving development. Decide which properties admins will edit in Experience Builder and which changes require a code release. A custom component can expose useful configuration, but someone must deliberately design that interface.

Verdict: Buy into custom LWC development when behavioral control is essential; skip it when configuration already solves the problem.

4. Salesforce Lightning Design System: best for custom UI styling

Salesforce Lightning Design System, commonly called SLDS, provides design guidance, styling conventions, and component blueprints. It helps teams build interfaces using established Salesforce patterns.

SLDS is included here as a design foundation, not a direct substitute for an installable Experience Cloud library. A visual blueprint does not implement your data retrieval, event handling, validation, or access rules.

Salesforce Lightning Design System pros:

• Provides shared terminology and patterns for interface design.
• Offers component blueprints that inform custom implementations.
• Gives designers and developers a common reference when reviewing UI decisions.

Salesforce Lightning Design System cons:

• Does not deliver a finished, functional Experience Builder component library.
• Leaves application behavior and integration to the implementation team.
• Does not make the completed page accessible without implementation and testing.

Best for: Teams designing and building custom Salesforce interfaces.

Use SLDS when the design language is the missing foundation. Do not select it as though installing a stylesheet will deliver a working portal workflow.

Verdict: Buy into SLDS as a design foundation; skip it as a standalone answer to a ready-made component requirement.

Validate the shortlist against a real page

For a 2026 evaluation, use one representative page rather than separate demonstrations that hide different weaknesses. Keep its data, user tasks, and acceptance criteria consistent across the approaches you compare.

Follow this sequence:

• Define the task: Write the user action and its successful outcome before selecting a component.
• Check the runtime: Confirm the intended site context before investing in configuration or code.
• Test access: Exercise the page as the users who will actually use it, not only as an administrator.
• Test interaction: Check validation, keyboard behavior, narrow layouts, loading states, and empty results.
• Assign ownership: Name the people responsible for configuration, code, package updates, and release checks.

Keep the test concrete. Define 3 user journeys: completing the main task, recovering from invalid input, and encountering restricted or missing data. These are evaluation recommendations, not claims about any library’s capabilities.

Check 2 viewport sizes that represent your intended desktop and mobile use. Then conduct 1 release rehearsal in your test environment, covering the configuration or package changes your implementation will need. These checks expose practical differences that a feature checklist misses.

How the ranking works

The 2026 order follows the job each option serves: packaged low-code components, native page building, custom component development, and custom interface design. It is not a benchmark of speed, accessibility, or feature coverage.

The criteria are builder fit, configuration depth, data access, interaction quality, and maintenance ownership. Your shortlist changes when the requirement changes: a simple native page and a custom transactional workflow should not automatically receive the same recommendation.

Which Experience Cloud approach should you choose?

Choose Avonni when your explicit requirement is a subscription-based no-code/low-code component library for Salesforce UIs. Validate the required Experience Cloud component before committing to the implementation.

If you are undecided, start with Salesforce standard Experience Builder components. Move to a packaged library when a documented requirement remains unmet; move to custom LWC development when you need behavior that configuration does not deliver. Use SLDS to guide custom design, not to replace functional components.

For your 2026 implementation, write down the reason for every added dependency. If the only reason is that a demonstration looked attractive, the selection is not ready.

FAQ

One last thing

The configuration boundary matters as much as the component itself. Ask the future page owner to change a field label, adjust a displayed option, and handle an empty result during evaluation.

If those ordinary tasks require code, document that dependency before launch. The best choice is the one your team can operate after the initial build, not just the one that produces an attractive first page.
