flutter-skill
AI-powered E2E testing for 10 platforms. 253 MCP tools. Zero config. Test Flutter, React Native, iOS, Android, Web, Electron, Tauri, KMP, .NET MAUI from natural language.
30-Second Demo
https://github.com/user-attachments/assets/d4617c73-043f-424c-9a9a-1a61d4c2d3c6
One prompt. 28 AI-driven actions. Zero test code. The AI explores a TikTok clone, navigates tabs, scrolls feeds, tests search, fills forms β all autonomously.
Why This Exists
Writing E2E tests is painful. Maintaining them is worse. flutter-skill takes a different approach:
- π Connects any AI agent (Claude, Cursor, Windsurf, Copilot, OpenClaw) directly to your running app via MCP
- π The agent sees your screen β taps buttons, types text, scrolls, navigates β like a human tester who never sleeps
- β Zero test code β no Page Objects, no XPath, no brittle selectors. Just plain English
- β‘ Zero config β 2 lines of code, works on all 10 platforms
You: "Test the checkout flow with an empty cart, then add 3 items and complete purchase"
Your AI agent handles the rest β screenshots, taps, text entry, assertions, navigation.
No Page Objects. No XPath. No brittle selectors. Just plain English.
Quick Start
1. Install (30 seconds)
npm install -g flutter-skill
2. Add to your AI (copy-paste into MCP config)
{
"mcpServers": {
"flutter-skill": {
"command": "flutter-skill",
"args": ["server"]
}
}
}
Works with Claude Desktop, Cursor, Windsurf, Copilot, Cline, OpenClaw β any MCP-compatible agent.
3. Add to your app (2 lines for Flutter)
import 'package:flutter_skill/flutter_skill.dart';
void main() {
if (kDebugMode) FlutterSkillBinding.ensureInitialized();
runApp(MyApp());
}
4. Test β just talk to your AI:
"Launch my app, explore every screen, and report any bugs"
That's it. Zero configuration. Zero test code. Works in under 60 seconds.

10 Platforms, One Tool
Most testing tools work on 1-2 platforms. flutter-skill works on 10.
| Platform | SDK | Test Score |
|---|---|---|
| Flutter (iOS/Android/Web) | flutter_skill | β 188/195 |
| React Native | sdks/react-native | β 75/75 |
| Electron | sdks/electron | β 75/75 |
| Tauri (Rust) | sdks/tauri | β 75/75 |
| Android (Kotlin) | sdks/android | β 74/75 |
| KMP Desktop | sdks/kmp | β 75/75 |
| .NET MAUI | sdks/dotnet-maui | β 75/75 |
| iOS (Swift/UIKit) | sdks/ios | β 19/19 |
| Web (any website) | sdks/web | β |
| Web CDP (zero-config) | No SDK needed | β 141/156 |
Total: 656/664 tests passing (98.8%) β each platform tested against a complex social media app with 50+ elements.
β‘ Performance
Real benchmarks from automated test runs against a complex social media app:
| Operation | Web (CDP) | Electron | Android |
|---|---|---|---|
connect | 93 ms | 55 ms | 103 ms |
tap | 1 ms | 1 ms | 2 ms |
enter_text | 1 ms | 1 ms | 2 ms |
inspect | 3 ms | 12 ms | 10 ms |
snapshot | 2 ms | 8 ms | 29 ms |
screenshot | 31 ms | 80 ms | 88 ms |
eval | 1 ms | β | β |
Token efficiency: snapshot() returns a structured element tree instead of an image β 87β99% fewer tokens than sending screenshots to your AI agent.
How fast is that? A tap takes 1β2 ms end-to-end. Browser automation tools like Playwright and Selenium typically take 50β100 ms for the same operation. That's 50β100Γ faster, because flutter-skill talks directly to the app runtime instead of going through WebDriver or CDP indirection.
Heavy DOM Sites (Real-World)
Tested 15 MCP tools against production websites β 75/75 passed, zero timeouts:
| Site | Tools | Total Time | snapshot | screenshot | count_elements |
|---|---|---|---|---|---|
| YouTube | 15/15 β | 6.9s | 43 ms | 30 ms | 4 ms |
| Amazon | 15/15 β | 14.2s | 1 ms | 5 ms | 2 ms |
| 15/15 β | 17.9s | 6 ms | 32 ms | 51 ms | |
| Hacker News | 15/15 β | 4.8s | 53 ms | 188 ms | 1 ms |
| Wikipedia | 15/15 β | 7.8s | 15 ms | 336 ms | 1 ms |
Total time includes page load. Tool execution is consistently sub-100ms even on heavy DOM sites.

π§ AI-Native: 95% Fewer Tokens
Most AI testing tools send screenshots to the LLM β each one costs ~4,000 tokens.
flutter-skill uses Chrome's Accessibility Tree to give your AI a compact semantic summary of any page:
// page_summary β ~200 tokens (vs ~4,000 for a screenshot)
{
"title": "Shopping Cart",
"nav": ["Home", "Products", "Cart", "Account"],
"forms": [{"input:Coupon Code": "text"}],
"buttons": ["Apply", "Checkout", "Continue Shopping"],
"features": {"search": true, "pagination": true},
"links": 47, "inputs": 3
}
Then batch multiple actions in one call:
// explore_actions β 5 actions per call (vs 5 separate tool calls)
{"actions": [
{"type": "fill", "target": "input:Coupon Code", "value": "SAVE20"},
{"type": "tap", "target": "button:Apply"},
{"type": "tap", "target": "button:Checkout"},
{"type": "fill", "target": "input:Email", "value": "test@example.com"},
{"type": "tap", "target": "button:Continue"}
]}
Result: Your AI agent tests faster, costs less, and understands pages better than screenshot-based tools.
| flutter-skill | Screenshot-based tools | |
|---|---|---|
| Tokens per page | ~200 | ~4,000 |
| Actions per call | 5+ | 1 |
| Understands semantics | β roles, names, state | β pixels only |
| Works with Shadow DOM | β | β |
