ResolveHQ is a self-hosted helpdesk platform built on Cloudflare Workers, D1, R2, and Queues, designed for small support teams. It features shared inboxes, email threading via RFC 5322, ticket management with roles and automation, file attachments, AI-drafted responses, and a public help center. The application runs as a single Worker and can operate on Cloudflare's Free plan with optional paid tiers for higher usage.
