Your team hates writing tests. But canaries don't.

AI agents that write and run tests for your mobile apps in the cloud. Unit tests, Espresso, XCUITest, Appium, Detox. Every PR spawns a canary that generates and executes tests before you merge.

// Features

Everything you need to ship mobile apps without fear

AI-Generated Test Scripts

Canary analyzes your PR diff and generates tests in your preferred framework. Unit tests, Espresso, XCUITest, Appium, or Detox.

The Skill System

Canary learns your libraries and patterns. Skills compound. The more you use it, the smarter it gets.

iOS & Android Native

Full support for React Native, Swift, and Kotlin. Tests run on real cloud simulators.

GitHub Integration

Connects via webhook. Every PR triggers analysis automatically.

Visual Regression

Pixel-perfect diffs catch unintended UI changes.

Context Retention

Canaries remember past tests. Failures come with full context.

// How it works

PRs spawn canaries. Canaries write tests. Tests grow with your releases.

Open a PR, meet your canary

Every pull request spawns a named canary agent. It reads your diff, understands the feature, and starts writing tests specific to your changes.

// PR #142: Add payment retry
🐤 Sage assigned

// Sage is analyzing...
→ Payment screen changes
→ New retry button
→ Error state handling

Tests run, context saves

Your canary writes tests, runs them, captures visual snapshots. Before merge, it saves its state so it remembers exactly what this feature does.

🐤 Sage // PR #142
✓ 12 tests written
✓ 12 tests passed
✓ 3 visual snapshots

State saved for release

Release with your full flock

When you cut a release, all canaries from merged PRs combine their tests. If something breaks, the canary that owns that test explains why, with full context.

// Release v2.4.0
🐤 Sage 12 tests
🐤 Ember 8 tests
🐤 Pip 15 tests

✓ 34/35 passed
✗ 1 failed → Sage reporting...
