+# SurfManager v2.0 - Go + Wails Migration
+
+## Overview
+
+Migrasi SurfManager dari Python/PyQt6 ke Go + Wails untuk performa lebih baik, single binary, dan UI modern.
+
+### Why Migrate?
+
+| Python (Old) | Go + Wails (New) |
+|--------------|------------------|
+| ~40MB binary + Python runtime | ~15-20MB single binary |
+| Startup ~1-2s | Startup <500ms |
+| PyQt6 dependency hell | Zero dependencies |
+| Complex build process | Simple `wails build` |
+| Limited UI customization | Full web UI (HTML/CSS/JS) |
+
+---
+
+## Tech Stack
+
+```
+Backend:  Go 1.21+
+Frontend: Svelte + TailwindCSS (lightweight & fast)
+Build:    Wails v2
+Icons:    Lucide Icons (modern, lightweight)
+```
+
+---
+

+
+## Go Backend API
+
+```go
+// app.go - Wails bindings
+
+type App struct {
+    ctx     context.Context
+    config  *config.Manager
+    process *process.Killer
+    backup  *backup.Manager
+    apps    *apps.Loader
+}
+
+// Reset Data
+func (a *App) ResetApp(appKey string) error
+func (a *App) GenerateNewID(appKey string) (int, error)
+func (a *App) LaunchApp(appKey string) error
+func (a *App) OpenFolder(appKey string) error
+
+// Sessions
+func (a *App) GetSessions(appKey string) ([]Session, error)
+func (a *App) CreateBackup(appKey, name string) error
+func (a *App) RestoreBackup(appKey, name string) error
+func (a *App) DeleteSession(appKey, name string) error
+func (a *App) SetActiveSession(appKey, name string) error
+
+// App Config
+func (a *App) GetApps() ([]AppConfig, error)
+func (a *App) AddApp(config AppConfig) error
+func (a *App) RemoveApp(appKey string) error
+func (a *App) ToggleApp(appKey string) error
+
+// Notes
+func (a *App) GetNotes() ([]Note, error)
+func (a *App) SaveNote(note Note) error
+func (a *App) DeleteNote(id string) error
+
+// Utils
+func (a *App) GetPlatformInfo() PlatformInfo
+func (a *App) KillProcess(names []string) error
+```
+

+
+## Data Compatibility
+
+**100% compatible** dengan data Python version:
+- Same folder structure: `Documents/SurfManager/`
+- Same JSON format untuk app configs
+- Same session storage format
+- Same notes format
+
+User bisa langsung upgrade tanpa kehilangan data!
+

+
+## Performance Targets
+
+| Metric | Python | Go Target |
+|--------|--------|-----------|
+| Startup | ~1.5s | <500ms |
+| Memory | ~80MB | <30MB |
+| Binary | ~40MB | <20MB |
+| Backup 100MB | ~5s | <2s |
+
+---
+
+## Next Steps
+
+1. **Run**: `wails init -n SurfManager -t svelte`
+2. **Setup**: TailwindCSS + Lucide icons
+3. **Implement**: Backend Go modules
+4. **Build**: Frontend components
+5. **Test**: Cross-platform
+6. **Release**: Single binary
