What Is Client App Builder in GoHighLevel? Branded Apps and Portals With AI

Short answer: Client App Builder is HighLevel's new AI tool, in Labs since October 28, 2026 (Official), for building on top of your Client Portal. You describe your business and the experience you want, and it generates either a branded Android app (published as an installable APK; iOS is listed as coming next) or a custom web portal through a mode HighLevel calls Vibe Coding, with up to 10 custom domains. Both stay connected to your courses, communities, files, appointments and member accounts, and a third release lets members create records in your CRM through custom objects. Pricing has not been announced yet.

What Client App Builder does

Until now the HighLevel Client Portal mostly looked the way HighLevel designed it. Client App Builder changes that. HighLevel announced three connected pieces in its changelog during LevelUp week, all available through Labs:

• Branded mobile apps with AI. Generates app screens, design and features from a description, applies your brand board (logo, colors, images), and brings in existing portal content such as courses, communities, files, appointments and member accounts. It includes sign in, sign up and member onboarding with join codes, plus native features such as camera and photo access.
• Vibe Coding for web portals. Builds a custom Client Portal website from plain language. The AI asks clarifying questions, suggests design inspiration and generates pages. You refine it by chatting or by selecting an element in the preview and describing the change, then publish, optionally on a custom domain (up to 10).
• Custom objects in Client App Builder. Members can submit information that is saved as records in your sub-account's CRM. You describe what you want, for example "Let members apply for a 1:1 coaching session", and the AI proposes the custom objects, fields, relationships, portal pages and workflows for you to approve.

In short, it turns the Client Portal from a course and community area into a branded app or site that can also collect structured data from your members.

Status, limits and cost

• Status: Labs. You turn on Client App Builder from Labs before any of this appears.
• Mobile platforms: Android only for now. Publishing generates an installable Android APK with build progress and errors shown. The changelog lists iOS publishing as coming next and does not mention submitting to the Google Play Store.
• Coming next (not available yet): mobile app templates, ready-made industry templates for portals, MCP integrations and faster app generation.
• Custom object limits: up to 3 objects per request and 10 custom objects per sub-account, so you may need to reuse existing objects.
• Payments: members can take payment actions on records through HighLevel invoices, but only if a payment provider is connected.
• Cost: not announced yet. None of the three changelog entries mention pricing or plan requirements.

How to build a branded app or portal, step by step

These steps combine the official changelog entries.

1. Turn on Client App Builder in Labs.
2. Open the builder and choose the type: Mobile for an Android app, or a web experience for a Vibe Coding portal.
3. Describe the business, the audience and the features you want. Be specific: who logs in, what they should see first and what they need to do.
4. Pick a design system and brand board, or add brand images.
5. Preview and refine. Use AI prompts, or on the web, click an element in the preview and describe the change.
6. Add data collection if you need it. Ask for a form such as a service request or an application, review the proposed custom objects, sample records and member visibility (own records, company records, or all records read only), then approve.
7. Publish. On mobile this produces the Android APK. On the web you publish the portal and can connect a custom domain.

Who it is for

• Coaches, course sellers and membership businesses that already use the Client Portal and want a branded app without hiring developers.
• Service businesses with repeat clients that want a client area for intake forms, service requests, files and appointments, with the data landing in the CRM where workflows can act on it.
• Agencies that sell portals or apps to clients and want to build them faster from a prompt.

Who should wait: anyone who needs an iPhone app or a Play Store listing today, or who needs a fixed price before committing. Those details are not announced yet.

Watch out for these before you build

• Plan your data first. With a limit of 10 custom objects per sub-account, decide which records you really need. Our guide on cleaning up unused custom fields covers the same discipline for fields.
• Set member visibility carefully. Members seeing other members' records would be a privacy problem. Test with two member accounts before you share the portal.
• Connect workflows on purpose. When the AI proposes workflows for new records, review each trigger and message so a submission does not start the wrong follow-up. See how to stop clients from breaking workflows.
• Labs features change. Keep a simple fallback, such as a standard form and calendar link, for anything critical.

What to do now

1. Turn it on in Labs in a test sub-account and build one small portal or app.
2. Start with one use case, such as a service request or an application form that creates a record and notifies your team.
3. Check member visibility, payments and the follow-up workflow end to end.
4. Only then roll it out to clients, and tell Android users how to install the APK.

If you want this built and connected properly, our GoHighLevel operations partner plan covers ongoing builds like this, and agencies can package it into an agency master snapshot. Or book a free discovery call.
