What is Local-First?

Local-first software prioritizes storing data on the user’s local device rather than in the cloud. Auk embraces this philosophy, giving you complete control over your API collections and environments.

​
Core Principles

​
1. Data Ownership

You Own Your Data:
  • Stored on your device
  • No cloud service required
  • No vendor lock-in
  • Export anytime
Benefits:
  • Privacy protection
  • Data sovereignty
  • Compliance friendly
  • No service dependencies

​
2. Offline-First

Work Without Internet:
  • All features available offline
  • No network latency
  • Sync when convenient
  • Resilient to network issues
Use Cases:
  • Airplane mode development
  • Poor network conditions
  • Remote locations
  • Security-restricted environments

​
3. Performance

Native Speed:
  • No API calls to cloud
  • Instant response times
  • Local file system access
  • Desktop app performance

  • Standard workflows
  • Familiar tools
Advantages:
  • No proprietary sync protocol
  • Works with existing infrastructure
  • Audit trail built-in
  • Branching and merging

Backup Strategy

Three-Tier Backup:
  1. Primary - Local workspace files
  2. Secondary - Git remote repository
  3. Tertiary - Manual archives
# Weekly backup script
#!/bin/bash
DATE=$(date +%Y-%m-%d)
tar -czf "auk-backup-$DATE.tar.gz" ~/Documents/Auk/
mv "auk-backup-$DATE.tar.gz" ~/Backups/

​
Git Repository Organization

Recommended Structure: 
company-apis/
├── README.md
├── .gitignore
├── team-a/
│   ├── collections/
│   ├── environments/
│   └── README.md
├── team-b/
│   ├── collections/
│   ├── environments/
│   └── README.md
└── shared/
    ├── common-collections/
    └── common-environments/

​
Security

Protect Sensitive Data:
  1. Use Secret Variables - Never commit secrets
  2. Separate Workspaces - Prod vs dev
  3. Encrypt Disk - Enable full disk encryption
  4. Private Repos - Use private Git repositories
  5. Access Control - Limit Git repository access

​
Performance Optimization

Keep Workspaces Lean:
  • Archive old collections
  • Limit history size
  • Clean up unused environments
  • Regular maintenance
File System:
  • Use SSD for better performance
  • Avoid network drives
  • Regular disk cleanup
  • Monitor disk space

​
Frequently Asked Questions

​
Is my data really private?

Yes. All data stays on your device unless you explicitly configure Git sync. Even with Git sync, you choose where data goes (GitHub, self-hosted, etc.).

​
What if I lose my device?

If you’ve configured Git sync, your data is backed up in the Git repository. Otherwise, regular backups are recommended.

​
Can I use Auk without Git?

Absolutely. Git sync is completely optional. Auk works perfectly as a local-only tool.

​
How do I share with my team?

Configure Git sync and share the repository URL with your team. They can clone the repository and sync their changes.

​
What about real-time collaboration?

Auk uses Git for collaboration, which is periodic rather than real-time. This is a trade-off for the local-first architecture.

​
Can I migrate back to cloud tools?

Yes. Export your collections and import them into any tool that supports standard formats (Postman, Insomnia, etc.).
