Overview

Subspace is a unified Mac workspace for AI coding agents. Run Claude Code, Codex, OpenCode, Gemini, Cursor, Copilot, Amp, Factory Droid, Kiro, and more side by side in a single app alongside terminals, docs, files, and an integrated browser — so you stop catching your agents up, because they already know. Its cross-agent memory compresses every conversation turn into token-efficient, structured observations tagged with decisions, blockers, and progress, making shared context portable across sessions and agents. Workspaces group related projects with their tools to cut window clutter, a Cmd+K command palette keeps the experience keyboard-first, and a comments system lets you leave feedback on code, terminal output, or browser content — with browser comments mapping back to the rendering components and source files via React fiber inspection. Currently macOS only (Apple Silicon); Windows and Linux are coming soon.

Pricing: $12/month or $99/year (14-day free trial, no credit card)
