Stack Architecture

• The system begins with Ollama — a local runner that functions like Docker for models — to maintain data privacy and eliminate inference costs for routine tasks.0:51
• A custom routing layer manages a three-tier fallback hierarchy: it defaults to existing subscriptions like Claude Max, rolls over to low-cost pay-per-token OpenAI models when quotas exhaust, and finally utilizes free options like Chinese open-weight models or trial credits.1:41
• Headroom functions as a context-compression layer, caching logs and tool outputs locally to strip nonessential metadata before they trigger billable input costs.2:33

Autonomous Workflow

• The deployment utilizes Hostinger as an affordable VPS host with a built-in Docker catalog, allowing for one-click deployment of the various open-source services.3:13
• Diffy serves as a visual builder for app logic, replacing prompt-only workflows with node-based automation that exposes finished functions as APIs.3:42
• OpenHands is integrated as an autonomous coding agent that purportedly ranks highly on the SWE-bench verified benchmark, allowing it to independently resolve GitHub issues in the background.4:26
