Which AI agents are compatible with Subspace?

Subspace supports a wide range of CLI agents including Claude Code, Codex, OpenCode, Gemini, Cursor, and Copilot. You can run multiple agents side-by-side in a single workspace, allowing you to switch between different models as your project needs change.

How does the shared memory feature work across different agents?

Subspace automatically captures background observations, decision logs, and status updates into a persistent memory layer. This context is shared across all agents in the workspace, so a new session or a different agent can immediately understand previous work without needing a full re-explanation of the codebase.

Subspace Review – Cost, Use Cases & Alternatives [2026]

AIChief Verdict

Subspace represents a massive leap forward for developers who rely on multiple autonomous agents. It effectively ends the frustrating cycle of re-explaining your codebase to every new tool. By centralizing memory, the platform ensures that context flows seamlessly between Claude Code and other CLI agents. Moreover, the keyboard-first design caters perfectly to power users who demand speed and efficiency. In our view at AIChief, the ability to run diverse models side by side is a game changer. You no longer have to choose a single vendor for your entire development workflow. Instead, you can switch between the best tools as the leaderboard changes. In addition, the background memory capture transforms these agents into genuine teammates rather than simple chat boxes. The workspace persistence means your progress remains intact even after a full system restart. While the Pro tier is necessary for full memory recall, the free version offers incredible value. Subspace is clearly built for the future of agentic work where coordination is king. We believe this app will become an essential hub for any serious agent-first builder.

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.
