| What makes it different | - All-in-one platform consolidating tools writers typically use across multiple services
- Independent, founder-owned company focused on user needs rather than investor targets
- Intentionally simple and easy to use without training or lengthy onboarding
- Token-based pricing applies across all features equally
- Switch between multiple AI providers mid-conversation
| - Import-first approach: reads existing configs from all your tools and converges them before you write YAML
- No marketing gloss: capability table generated at build time from actual adapter code, not hand-maintained
- Portable across tools: single harness.yaml travels with you to every machine and tool
- Open source and free: no cost beyond existing Claude subscription
- Based on open specification: Harness Protocol is vendor-neutral and JSON Schema validated
