HarnessRouter

HarnessRouter provides a unified API to run AI agent harnesses like Codex and Claude Code in isolated sandboxes, returning finished artifacts instead of raw tokens. It targets developers and engineering teams at startups and enterprises who want to integrate AI agents into their products without building backend infrastructure. The service handles sandbox provisioning, tool orchestration, streaming, and cost controls, positioning itself as a managed backend that saves months of development time.
