Add a project
Point Subspace at a folder. It creates workspaces for your project and any worktrees, and backfills memory from your recent agent sessions.
Work the way you already do
Launch Claude Code, Codex, or OpenCode from the command palette. Your agents run in Terminals, you can open docs & files, view your website in the browser, and more.
Every session starts informed
Memory builds automatically so tomorrow’s first session already knows what today’s sessions accomplished, decided, and left open.
Your agents already know
Hit /clear and everything’s gone. The decisions. The dead ends. The plan. You’re back to re-explaining it all.
Subspace builds memory in the background. Every conversation turn is compressed into a token-efficient observation with structured tags — decisions, blockers, progress. Every few turns, a status update synthesizes recent work into a clear picture of where things stand. Your agents can search this memory mid-session — by text, tag, workspace, or timeline.
When a new session starts, that context is already there. Claude Code context flows to Codex and OpenCode. The memory belongs to the workspace, not any single tool. Everything Subspace remembers is visible in the app — no black box.
Any agent. Any model. All at once.
You shouldn’t have to pick one agent and hope it’s the best at everything. Run any CLI agent side by side — Claude Code, Codex, OpenCode, Gemini, Cursor, Copilot, Amp, OpenClaw, Kiro. Use the best tool for each task.
When one gets stuck, tag in another — it already knows what’s been tried. Memory is shared across every agent in the workspace (Claude Code, Codex, and OpenCode to start). The sidebar shows which are working, which need input, which are done.
Organize the chaos
Agents made you faster. Your tools didn’t keep up. You’re Alt-Tabbing between terminals, editors, browsers, git clients, and notes apps — more windows than ever, less visibility than ever.
Subspace puts all of it in one app. Agents, terminals, docs, files, browser, and git — grouped into workspaces, persisted across restarts. Switch between projects in under 100ms.
Cmd+K. That’s it.
One input for everything. Launch an agent with a typed prompt. Switch workspaces. Open files. Run shell commands. Search your browser history. Between the palette and keyboard shortcuts, you barely touch the mouse — Subspace was built keyboard-first from the ground up.
Highlight. Comment. Fix.
Select any text on your site and leave a comment. Your agent gets the request with the exact source file, component name, and line number already attached — pulled from the React fiber tree. No grepping. No “I think it’s in Header.tsx.”
Highlight anything on the page to jump straight to the code that renders it. The browser is a workspace pane, right next to the terminal. You direct from what you see. The agent works from where it lives.

Where agents & humans work together.
It's time to build.
Reply to your agents like a colleague
Select text in a terminal, doc, or browser and leave a comment — exactly like reviewing a colleague’s work. Queue up feedback from multiple spots and send it as one batch. Browser comments even trace to the source component and file — so your agent knows exactly what you’re pointing at.
