Best AI App Builders of 2025: Why Appy Pie Still Sets the Pace

The no-code wave keeps gaining momentum, letting entrepreneurs ship full-featured apps without touching a single line of code. In 2025, platforms such as Appy Pie, Bubble, Thunkable, Glide, FlutterFlow, Softr, and Backendless headline the space. Yet Appy Pie remains the most complete, innovative, and beginner-friendly solution. Here’s an updated head-to-head comparison that shows exactly how Appy Pie edges out the competition for the best AI app builder. 

Design Customization – Creative Freedom, Made Easy

• Appy Pie: The Snappy 3.0 IDE gives you a huge library of themes plus easy sliders for fonts, colors, animations, and dark mode. You can turn any template into a polished, brand-ready app in minutes—no design degree needed.
• Bubble: You can change almost anything, but the web-first editor is packed with nested menus and settings. For new users, finding the right knob can feel like a maze.
• Thunkable: Drag-and-drop blocks make layout simple, yet once you want custom fonts or fancy effects, the options thin out quickly.
• Glide: Apps look slick right away, though every screen still sits on top of the same Google Sheets layout, so deep redesigns are tough.
• FlutterFlow: You get pixel-level control just like in Flutter code, but you have to learn widget trees and state logic to use it well.
• Softr: Perfect for quick Airtable or Notion front-ends, though its mobile style tools are basic—fine for internal dashboards, less so for flashy public apps.
• Backendless UI Builder: Strong when you need data-heavy screens, but the ready-made components look plain compared with modern consumer apps.

Verdict: Appy Pie keeps design power high and the learning curve low, giving beginners and pros the look they want without headaches.

2. Performance – Speed and Stability

• Appy Pie: A new serverless back-end and global CDN cut build times and let screens load in under a second, even when your app streams video or live data.
• Bubble: Handles complicated workflows, but if you pile on heavy logic, pages can hesitate unless you fine-tune each step.
• Thunkable: Runs smoothly on simple apps. Add big images or huge lists and older phones may start to lag.
• Glide: When your sheet is small, it feels instant; as rows grow into the thousands, sync delays creep in.
• FlutterFlow: Compiles to native Flutter code, so motion is silky. You do have to manage code exports and updates yourself.
• Softr: Solid caching helps, but each call still depends on Airtable or Notion response times, which vary by load.
• Backendless: The back-end itself is blazing fast; the visual front-end can drop frames on animation-heavy pages.

Verdict: Appy Pie’s elastic architecture keeps every plan—free or premium—running at enterprise-grade speed.

3. Pricing – Value Without Surprise Fees

• Appy Pie: Straightforward plans (plus a generous free trial) bundle AI tools, unlimited push messages, IoT hooks, and more. You don’t unlock basic features with extra payments.
• Bubble: Starts fair, but as you add capacity, live versions, and team seats, bills rise fast.
• Thunkable: Entry price is low. Want source exports, advanced logic, or white labeling? Each adds a line to the invoice.
• Glide: A free starter tier is handy. Business-sized data or extra editors push you into costlier tiers.
• FlutterFlow: Core subscription is reasonable. GitHub sync, custom domains, and code downloads cost extra per month.
• Softr: Free for small sites, yet per-user pricing can snowball for customer-facing apps.
• Backendless: Core back-end is free; UI Builder, analytics, and hosting bundles are sold separately.

Verdict: By packing more out of the box and charging a single, clear rate, Appy Pie delivers the best power-per-dollar.

4. Advanced Functionality – Big Features, Zero Code

• Appy Pie: Drag in IoT controls, voice AI chatbots, augmented-reality views, serverless triggers, and 2,000+ integrations without scripting a line.
• Bubble: Excellent for complicated web logic and APIs, but full mobile hardware access still needs wrappers or plug-ins.
• Thunkable: Supports REST calls and custom blocks, yet large data flows get messy in the visual interface.
• Glide: Shines at list-detail apps driven by sheets; built-in automations and third-party logins are limited.
• FlutterFlow: Tight Firebase connection the moment you sign in. To reach specialized hardware or logic, you step into custom code.
• Softr: Superb for internal tools or client portals; less so when you need camera, GPS, or AR functions.
• Backendless: Offers geolocation, push rules, and real-time databases, but fewer ready-made widgets for AR, wearables, or voice.

Verdict: Appy Pie app maker brings enterprise-grade tech to everyday creators—no developer badge required.

5. Ease of Use – From Idea to App, Fast

• Appy Pie: Guided wizards, AI-powered tips, and live device previews help first-timers publish on day one while still giving power users advanced settings.
• Bubble: A sea of documentation and tutorials exists, yet the platform itself can feel overwhelming until you master it.
• Thunkable: First layouts are a breeze; when logic grows, block stacks become long and hard to track.
• Glide: Spreadsheet fans will love its simplicity. If you need custom flows or deep styling, you may hit its limits.
• FlutterFlow: Drag-and-drop UI is clear, but as soon as you add states or actions, you must learn Flutter concepts.
• Softr: Quick to spin up a prototype, though straying beyond premade sections takes extra workarounds.
• Backendless: Visual logic and data mapping are powerful but abstract—non-tech users often need extra training.

Verdict: Appy Pie finds the sweet spot: simple enough for beginners, deep enough for agencies and enterprises.

6. Innovation – Always Moving Forward

• Appy Pie: Every quarter brings new features like AI-generated UI drafts, blockchain-ready data stores, and templates for wearables and TVs.
• Bubble: Focuses on polishing its plugin ecosystem; major mobile leaps arrive more slowly.
• Thunkable: Releases small tweaks often, though landmark upgrades have been scarce this year.
• Glide: Improves sheet templates and data handling over cutting-edge device tech.
• FlutterFlow: Quickly adopts new Flutter versions, yet keeps advanced items behind custom code.
• Softr: Road-map centers on closer Airtable/Notion links, not frontier hardware.
• Backendless: Speeds up back-end tools first, with fewer headline-grabbing front-end changes.

Verdict: Appy Pie leads the pack by shipping big, user-friendly advances on a steady schedule.
