Terminal Use, a Y Combinator W26 startup, has launched a platform that simplifies deploying agents requiring filesystem access. Founded by Filip, Stavros, and Vivek, the service addresses a common pain point: stitching together packaging, sandboxing, streaming, state persistence, and file management for agents.

Inspired by Replicate's Cog, Terminal Use lets developers package agent code from a repo using config.yaml and Dockerfile, then deploy via CLI. The platform supports Claude Agent SDK and Codex SDK out of the box, with adapters converting SDK message types to Terminal Use's protocol. Developers can also use custom harnesses compatible with Vercel AI SDK v6.

The platform's standout feature is treating filesystems as first-class primitives, separate from task lifecycles. This allows workspace persistence across turns, sharing between agents, and independent file uploads/downloads via presigned URLs. The decoupled architecture enables easy iteration—developers can deploy bug fixes and auto-migrate tasks, or maintain separate versions for breaking changes.
