Best App Builder for Agencies in 2026

TL;DR

The best app builder for agencies depends on whether you want to build and own real apps for clients or resell a templated platform under your own brand. For agencies that build, CatDoes ranks first: it ships native mobile apps and websites from a prompt, includes a full backend on every plan, and lets you export the code so you are never locked in. For turnkey reselling, Appy Pie offers a white-label program where you set client pricing. Below we compare five tools on white-label, code ownership, backend, and price.

What Agencies Actually Need From an App Builder

Building apps for clients is a different job than building one app for yourself. The same six things come up on every project.

• White-label branding. Clients should see your brand, not the platform's. That means no "made with" badge, plus custom domains and login screens.

• Code ownership. If a client app outgrows the tool, you want to hand the source to developers instead of starting over. Lock-in is the biggest long-term risk.

• Backend included. Auth, database, storage, and APIs are needed on nearly every app. Wiring up a separate Firebase or Supabase per client adds cost and setup time.

• Speed. Agencies live and die on delivery time. The faster you ship a working build, the better your margins.

• Multi-project management. One place to manage every client project, ideally with per-client permissions.

• A revenue model that compounds. Either recurring client subscriptions or a clean one-time handoff with upsells.

There are two camps. Reseller platforms (like Appy Pie) hide the underlying tool and let you set your own prices. Build-it-yourself white-label tools (CatDoes, Bubble, Glide, and Adalo) give you the branding controls, but you own the build and the client relationship. Pick based on whether you sell software or sell a service.

Quick Comparison of App Builders for Agencies

A fast side-by-side. Prices are starting points as of mid-2026 and should be verified on each vendor's site, since several restructured pricing in the last year.

The 5 Best App Builders for Agencies

1. CatDoes: Best Overall App Builder for Agencies

CatDoes is an AI agent that builds native mobile apps and websites from natural language, then deploys them to the App Store, Google Play, or the web with custom domains. Instead of dragging components onto a canvas, you describe what the client needs and a cloud agent writes the code, installs packages, runs tests, and fixes its own errors. It keeps working after you close the tab.

For agencies, three things make it stand out. First, CatDoes Cloud is included on every plan, even the free one. That means database, auth, storage, edge functions, and realtime are ready to go without setting up Firebase or Supabase per client. Second, it builds on standard frameworks (React Native Expo for mobile, Next.js and Vite for web) and offers full code export and two-way GitHub sync, so a developer can take over any project. No lock-in. Third, it handles both native mobile and web from a single project, including a website-to-app feature that turns an existing URL into an app.

White-label fits the build-it-yourself model: removing the CatDoes badge unlocks on paid plans, and apps ship under your client's brand and domain. Pricing starts with a free tier (good for prototyping a pitch), with paid plans from around $20/month and higher tiers adding more credits, projects, code export, and App Store and Google Play deployment. See the current breakdown on the CatDoes pricing page.

Best for: agencies and freelancers who want to ship real, ownable apps for clients fast, with a backend already wired in.

2. Bubble: Best for Complex Web Apps

Bubble is option for web applications with heavy logic and workflows. White-labeling is included on any paid plan, and it offers a dedicated agency account, though there is no true wholesale reseller program. You build and own the product yourself.

Two things to plan around: Bubble bills on usage-based "Workload Units," which makes real costs hard to predict and is the single most common complaint, and it is not native mobile, so shipping to the App Store needs a wrapper. Paid plans start around $29/month but real-world active apps often run far higher.

3. Glide: Best for Client Portals and Internal Tools

Glide builds apps and portals from spreadsheets and databases, and it is genuinely fast. White-label branding with a custom domain starts on the Maker tier, and Glide maintains a dedicated agency plan that points larger teams to Enterprise for unlimited editors.

Watch the seat and per-user limits: lower tiers cap editors, and usage-based "update" overages add some unpredictability. Maker starts around $49/month, with Business near $200/month and Enterprise from roughly $750/month.

4. Adalo: Best Simple Native Builder

Adalo is a friendly drag-and-drop builder for native mobile and web apps. Its Business tier allows unlimited published apps, which makes it attractive for agencies, and a "database-driven branding" trick lets one codebase serve many clients. Pricing is flat-rate with no usage fees, which is refreshing.

The major caveat is no code export and full lock-in: stop paying and the app stops working, with no migration path. Starter plans begin around $36/month, with the unlimited-apps Business tier near $200/month.

5. Appy Pie: Best for a Fast Reseller Launch

Appy Pie runs an aggressive white-label reseller program where clients never see the Appy Pie brand. You get a multi-tenant dashboard, control branding and pricing, and Appy Pie handles publishing and maintenance. Its marketing pitches launching a reseller business quickly at high margins.

Reseller pricing is not public and requires contacting sales, and the standard white-label add-on roughly doubles the base plan price. Apps are template-based with no code export.

How to Choose the Right App Builder for Your Agency

Start with your business model, not the feature list. If you sell a productized, recurring subscription under your own brand and the apps can be template-based, a reseller platform like Appy Pie removes the most friction. If you sell custom software as a service and want each app to be a real, ownable asset, a build-it-yourself tool wins.

From there, weigh four questions:

1. Do you need native mobile, web, or both? CatDoes and Adalo cover native mobile. Bubble and Glide lean web.

2. How important is code ownership? If clients may scale beyond the tool, prioritize export. CatDoes delivers real, exportable code; the others lock you in.

3. Do you want the backend handled? CatDoes includes it on every plan, so you skip wiring up Firebase or Supabase per client.

4. How fast do you need to ship? AI-first tools like CatDoes compress the first working build from weeks to hours, which protects margins on fixed-bid projects.

For most agencies that build rather than resell, CatDoes hits all four: native and web, real code export, a backend that is already wired in, and AI speed. You can prototype a client pitch on the free plan before committing. Browse more guides on the CatDoes blog to go deeper on any tool.

Frequently Asked Questions

What is the best app builder for agencies?

For agencies that build and own client apps, CatDoes is the strongest all-around choice because it ships native mobile and web apps from a prompt, includes a backend on every plan, and supports full code export. For agencies that want to resell a templated platform under their own brand with their own pricing, Appy Pie leads.

What is a white-label app builder?

A white-label app builder lets you remove the platform's branding so the finished app, and sometimes the entire build dashboard, carries your client's brand instead. Some tools only remove an in-app badge, while full reseller platforms also white-label the admin panel, login screens, and emails.

Can agencies resell apps built with these tools?

Yes. Reseller platforms like Appy Pie are designed for it, letting you set client pricing with no commission. With build-it-yourself tools like CatDoes, Bubble, Glide, or Adalo, you can still charge clients whatever you want, but you manage the build and the relationship directly rather than through a reseller dashboard.

Which app builders let you export the code?

CatDoes (on Plus plans and up) exports real source code, so you are not locked in. Most no-code tools, including Adalo, Glide, Bubble, and Appy Pie, do not offer code export.

How much do app builders for agencies cost?

Entry white-label tiers run roughly $20 to $60 per month. Mid-range agency and reseller tiers typically land between $140 and $250 per month. Enterprise and high-volume plans go well beyond that. Always confirm current pricing on each vendor's site, since several changed pricing in the last year.

The Bottom Line

There is no single best app builder for every agency, but there is a clear best fit for each model. If you resell templated apps under your own brand, Appy Pie gives you reseller mechanics. If you build custom apps you and your clients actually own, CatDoes is the standout: native mobile and web from a prompt, a backend included on every plan, full code export, and AI speed that protects your margins.
