Frequently Asked Questions
Everything you need to know about Cold Runner
macOS 11+ with 8GB RAM minimum (16GB recommended). Works on both Apple Silicon (M1/M2/M3/M4) and Intel Macs. You'll also need Ollama installed for local AI inference.
Only for optional features like Brave Search (lead discovery) and Hunter.io (email finding). Core functionality including AI-powered email generation works 100% offline with no API keys required.
Any Ollama model works, but we recommend 7B parameter models for best performance: Mistral (best balance), Llama 3.2 (fastest), or Qwen 2.5 (great for technical content). The built-in setup wizard helps you install Ollama and download models.
Yes, completely. All data stays on your machine in a local SQLite database. No cloud sync, no telemetry, no data collection. Your leads, emails, and campaign data never leave your laptop.
Yes. Cold Runner is MIT licensed open source software. No subscriptions, no hidden costs, no premium tiers. The only costs are optional API keys for third-party services (Brave Search, Hunter.io) if you choose to use them.
Absolutely. Cold Runner supports multiple outreach types: job applications, sales, partnerships, and investor outreach. The adapter system makes it easy to add custom outreach types for your specific needs.
