Catalog comparison
DetoxAstur
Side-by-side facts from the TestGuild Tool Matcher catalog. Empty cells mean the catalog does not list that attribute — not that the product lacks it.
Open-source end-to-end testing framework for React Native mobile applications that enables testing of any end-to-end flow with maximum velocity and zero flakiness using gray box testing approach
Open-source device-native mobile automation toolkit that brings Playwright Test ergonomics to Android and iOS—without an Appium server or WebDriver layer. One test API for native, Flutter, and React Native apps via UIAutomator (Android) and XCUITest (iOS) agents, with Dart VM widget-tree inspection for Flutter on Android and DOM-level WebView control. Includes live inspector, codegen, fixtures/locators/assertions/retries/reports, and npm packages (@astur-mobile/test, astur-mobile). Apache-2.0; early beta (npm next channel).

Key features (catalog)
Detox
Access to app internals, Animation handling, Asynchronous operation handling, Automatic synchronization, Built-in assertions, CI/CD integration, Cross-platform testing, Deterministic testing, End-to-end testing for React Native, Functional testing +10 more
Astur
Android UIAutomator and iOS XCUITest native agents, Codegen that exports reusable @astur-mobile/test specs, Flutter widget-tree inspection via Dart VM (Android) and XCUITest tree (iOS), In-app WebView DOM control from the same test API, Live device inspector with ranked semantic locators, No Appium server or WebDriver compatibility layer, Open-source Apache-2.0 npm packages, Playwright-style fixtures, locators, assertions, retries, and reports for mobile, React Native via testID / accessibility on native agents, Single monorepo for drivers, agents, CLI, examples, and docs
Limitations (catalog)
Detox
JavaScript/TypeScript only, Learning curve for gray box concepts, Limited to mobile testing, Mobile platforms only, React Native only, Requires React Native setup
Astur
Early beta — expect API and tooling churn vs mature Appium ecosystems, Flutter deep inspection paths differ by platform (Dart VM primarily called out on Android), iOS real devices need Apple signing for the XCUITest runner, Smaller community and download base than Appium/Maestro today, TypeScript/JavaScript Playwright-style API — not a no-code product

How the trade-offs apply to your team
Guidance below is inferred only from catalog differences. It is not a winner pick.
Consider Detox if…
- you need coverage for Android Emulator, iOS Simulator
- open source matters for your team
- you care about Access to app internals and Animation handling
Consider Astur if…
- you need coverage for ci/cd, cli, emulators, flutter
- you care about Android UIAutomator and iOS XCUITest native agents and Codegen that exports reusable @astur-mobile/test specs
Questions to verify before choosing
- Confirm current pricing and packaging on the Detox and Astur websites.
- Trial both tools against a real slice of your application, not a demo site.
- Verify the exact browser, device, or OS matrix you must support.
