Subspace

What it does

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.

The free, agent-first workspace for Agent Chat, CLI agents, Topics, Shared Memory, comments, artifacts, and Git—from first question to shipped work.

Use the best agents and models from one fast, keyboard-first Mac app . Every Topic keeps its sessions, terminals, docs, files, websites, Git, and Shared Memory together—so parallel work stays clear and every new session starts caught up. Choose the intelligence, do the work, carry the context, and review the result from one fast, keyboard-first app built for product builders. Open Agent Chat or launch supported CLI agents with the access you already have. Inside Claude Code, reach leading open-source, proprietary, and frontier models through OpenRouter. Sessions, terminals, docs, files, websites, comments, artifacts, and Git workflows stay with the feature, fix, or exploration they belong…from subspace.build

  Today we’re excited to introduce AgentSea, a private AI chat built for sensitive work. When you use closed-source AI models, your data can: – be stored – pulled into training pipelines – shared with third parties That might be fine if you’re making memes or drafting LinkedIn posts. But it becomes a serious risk when you’re pasting contracts, health info, financial data, or business secrets. That’s why we built AgentSea. In Secure Mode, all chats run on open-source models or models hosted on our own servers. Your data never leaves, is never used for training, and is never leaked. Agentsea…

  Hey HN! I'm Connor, creator of Replicas. I'm a heavy Codex/Claude Code user, and I wanted to hand off tasks to agents like I would to an engineer - kick something off before work, let it scaffold while I'm at lunch, even come back to a ready PR. The problem: existing alternatives use workspace VMs that are black boxes. I have no access to any of them - they can't run tests, read logs, or use tools like the Playwright MCP (which I use to verify agents actually fixed what they claim to fix). Replicas gives agents real cloud workspaces where they can: - Run your test suite and read the…

  Hey HN, We're Cosmic (YC W19), a headless CMS. Today we're launching Team Agents and the Cosmic Agent. Team Agents are AI-powered team members that live in Slack, WhatsApp, and Telegram.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
