Subspace is an Agent Workspace built for the age of Agentic Engineering. 1) Run Claude Code, Codex, OpenCode, Gemini, and more side-by-side in a single app. 2) Workspaces organize your agents, chat history, terminals, docs, files, and browser with a keyboard 1st design. 3) Subspace Memory works in the background, so every new chat session picks up where the last one left off and your agents become collaborators instead of tools.
Before Subspace, I was juggling 4–5 terminal windows with 8-way splits, a handful of Cursor/VS Code windows, GitHub, Chrome with 100 tabs, Obsidian, and more. Every new agent session started from zero. Every morning I'd dig through terminal panes and markdown docs (so many markdown docs) just to figure out what I was doing yesterday.
The tool we wanted didn't exist. So we built it.
Subspace is an Agent Workspace — not a terminal, not an IDE — where you work *together* with your agents, where your agents remember the work like a real colleague, and where you pick up exactly where you left off.
Every project/worktree gets its own Workspace with agents, terminals, docs, browser, and memory grouped together. Memory runs in the background across sessions — so every new agent session already knows what was accomplished, what was decided, and what's still open. Your agents can search it too.
**You can finally stop repeating yourself. They already know.**
And Memory works across Claude Code, Codex, and OpenCode (more soon). I switch between Claude Code and Codex constantly — being able to tag in a fresh agent mid-task without a handoff prompt has been the single biggest unlock for how I work.
We shipped an alpha on New Year's Eve, a beta end of January, and today we're launching the full product — workspaces, memory, multi-agent, command palette, comments, the browser, pricing, all of it.
**Free 14-day trial, no credit card. $12/month or $99/year after. Mac (Apple Silicon) only today — Windows and Intel are on the roadmap.**
I'll be here all day. Hit me with your hardest questions — architecture, product strategy (any PMs out there??), memory details, why-not-Cursor, the Anthropic-builds-it-first risk, anything. 🚀

Who hunted Subspace?
Subspace was hunted by Joe Fernandez. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
