Final Code vs Appetize.io

Bottom line

Choose Appetize.io if you want to show a mobile app inside a browser: a live demo on your website, a sales call, a support agent walking a customer through a screen, training for a contact centre, or automated tests that run in the cloud. Nobody has to install anything, and it works on any computer.

Choose Final Code if you are building the app and want to test it as you go on real iPhones and Android phones, plus iOS Simulators and Android Emulators, in one window on your Mac. Changes appear instantly on simulators and emulators, real phones get release builds, and nothing is uploaded.

They overlap less than you might think. Appetize is mostly about sharing a running app with people and systems. Final Code is mostly about the developer's own build and test loop.

What Appetize.io is good at

Appetize describes itself as cloud mobile emulators and simulators for Android and iOS apps that run in a web browser with no plugins or downloads. From its website at the time of writing:

• Pick iOS or Android versions and devices, and set language, location and other options.
• Embed the running app in your own products, tools and pages.
• Restrict which apps can run, use allowlists and a kiosk mode.
• Script logins and onboarding before a session, or during one.
• Inspect the UI hierarchy, debug logs and network traffic.
• A CLI, a REST API, CI/CD integrations and automated testing with Playwright; it also says AI coding tools can connect to it.
• Its site shows ISO 27001, SOC 2 Type II and GDPR badges.

For a product page demo or a help desk, that is hard to beat. An app preview that opens in a browser tab is a lovely thing.

Comparison table

Getting set up

With Appetize, you sign up, upload a build of your app and get a link or an embed. The free plan needs no card. The only real requirement is that you already have a built app file.

Final Code starts one step earlier, with your source code. Open a folder, or a repository from GitHub in one click, and Final Code recognises Expo, React Native, Flutter, native iOS and Android, Capacitor, Ionic, web apps and games. It installs anything the Mac is missing from the Tools screen. You never need to produce an app file by hand.

Speed of the feedback loop

A browser-streamed device is quick to open. The slower part, if you are developing, is getting each new version there: build, upload, reload. That is fine for a weekly demo build and less fine for twenty small tweaks before lunch.

In Final Code, saving a file updates every open simulator and emulator instantly. Real phones get a release build straight from your Mac in seconds to minutes. Native code is only rebuilt when it changed, and caches keep later builds short. And because it is all local, there is no minute meter running in the background.

Simulated devices vs real phones

Appetize runs simulators and emulators in the cloud, which is ideal for showing an app to someone. It is not the same as holding a phone. Touch, scrolling feel, performance on real hardware, camera and sensors are things you only fully judge on a device.

Final Code gives you both kinds. iOS Simulators and Android Emulators are mirrored in its window, where you can click, swipe, type and rotate them. Real iPhones and Android phones sit in the same list, running real release builds. The per-device inspector covers orientation, light and dark appearance, larger text, network (Wi-Fi, 5G, offline), GPS presets and battery level. For web apps there are iPhone, iPad, Android and foldable screen shapes too.

Development builds and release builds

Appetize runs the build you upload, whatever kind it is. Final Code handles both kinds for you: live development on simulators and emulators, and release builds with the code inside on real phones, so you test what users will get. Every phone build goes into build history with its commit, date and size, and you can reinstall any of them in one click.

Debugging and crash reports

Appetize lets you look at debug logs, network traffic and the UI hierarchy during a session, which is useful for support teams and testers.

Final Code goes deeper into the development side. Project check runs when a project opens and when new code arrives, catching libraries that do not match the Expo version, React Native APIs removed in your version, missing babel plugins and missing files. The Issues box gathers each error, crash and failed build once, with counts, device, stack and the log lines just before, and closes it when it stops happening. In version 0.5.0, "Share problem" builds one tidy report, removes passwords, keys and tokens, and "Explain this problem" has Claude explain it in plain words with steps.

Working with AI coding tools

Credit to Appetize: its site says AI coding tools can connect to it, and agents can target UI elements by name. Final Code also takes AI seriously, from a local angle. Your assistant reads the .finalcode folder in the project for live status, logs, issues, screenshots and the build log, and asks Final Code to build, run, reload, tap, swipe, type and read the phone log, on simulators and on real phones. When it pushes to GitHub, Final Code pulls the commit and rebuilds. More on our AI app builders page.

Price

At the time of writing, Appetize lists a free plan with 30 minutes a month, 3-minute sessions and 2 active devices; a Starter plan at $59 a month with 500 minutes; and a Premium plan at $319 a month with 500 minutes and more devices at once, with extra minutes at $0.06 each and Enterprise pricing on request. Check Appetize's pricing page for current figures.

Final Code is $29 a month or $249 a year after a free 14-day trial with no card, used as much as you like on up to 3 Macs. See pricing. Because the two tools do different jobs, many teams can justify both.

Privacy

Using Appetize means uploading your app to its cloud, which is the whole idea, and it publishes compliance badges for that. Final Code keeps your code on your Mac. It has no analytics, and the membership check sends only your email, plan and a one-way code for the Mac.

Who should use which

• Marketing and sales teams: Appetize, to put a live app on a web page or in a demo.
• Support and training teams: Appetize, to walk customers and staff through the app in a browser.
• Developers, indie or in a studio: Final Code for daily building and testing on real devices.
• People building with AI tools on a Mac: Final Code, so the assistant can test on real phones. See also web apps if you build for the browser.

Using Appetize and Final Code together

Build and test in Final Code until a version is solid on your own iPhones, Android phones, simulators and emulators. Then upload that build to Appetize and drop the embed into your landing page or send the link to a client. When the client spots something, reproduce it in Final Code with the matching build from build history, fix it, and upload the next version.
