What is Subspace?

Subspace is an agent-first workspace designed to streamline the workflow of developers and power users who utilize multiple AI agents simultaneously. Built for those who find traditional chat interfaces or standard terminals limiting, it provides a unified environment where CLI agents like Claude Code, Codex, and OpenCode run side-by-side. The platform solves the problem of fragmented context by implementing a shared memory system that captures background observations and decision logs across sessions. This allows users to switch between different agents without re-explaining their codebase or project status. With a keyboard-first design and sub-100ms workspace switching, it caters to high-velocity developers managing complex, multi-agent projects. Beyond just a launcher, it integrates browsers, git clients, and documentation into a single, cohesive interface. Subspace transforms the individual agent experience into a collaborative organizational structure for local AI development.
