Terminal Use (YC W26) is a deployment platform for filesystem-based AI agents, positioning itself as 'Vercel for agents'. It lets developers package agent code from a repo using a config.yaml and Dockerfile, then deploy via CLI. Key features include lifecycle endpoint definitions (on_create, on_event, on_cancel), built-in support for Claude Agent SDK and Codex SDK, Vercel AI SDK compatibility, and first-class filesystem primitives that are decoupled from task lifecycle. This decoupling enables persistent workspaces across turns, file sharing between agents, presigned URLs for direct user uploads/downloads, and seamless agent versioning with auto-migration. The platform also supports CI/CD pipelines, preview/production environments, git-based targeting, and CLI-driven testing workflows.
