Host your own background coding agent on Render

Running coding agents on Render can provide persistent, remotely managed infrastructure compared with laptop-based setups, using either the OpenCode template or the self-hosted Cursor agent template. OpenCode deploys as a single web service with a persistent disk that preserves its workspace, sessions, and some credentials across restarts, while Cursor separates a public trigger API from a long-running background worker that clones repositories afresh on startup and keeps execution capacity available. The guide emphasizes selecting service types based on inbound networking needs, storing repository changes durably or pushing them to Git, managing model and Git credentials through Render environment variables rather than source files, and designing long-running tasks to avoid web-request time limits and free-tier spin-downs. It also warns that OpenCode is a single-tenant deployment rather than a hardened sandbox, that its startup process copies certain API keys onto persistent storage, and that Cursor’s public task endpoint must be secured before deployment because an unauthenticated endpoint could let outsiders launch agents against a repository. Users should choose adequate paid compute resources, avoid redeploying during active agent work, use dedicated or service-account credentials where possible, and consider the tradeoff between Cursor’s warm long-lived workers and more isolated single-use workers.
