Nuphos is open source and self-hostable, plus three new agents

October 5–11 was our biggest week yet. Nuphos is now open source under Apache 2.0 and you can self-host every part of it, three new agents join Claude Code and Codex, and every session gets its own sharing controls. The first Nuphos CLI also shipped.

Open source and self-hostable

Nuphos is now open source under the Apache 2.0 license. Desktop, the backend, the agent runtime, the iOS app and the CLI now live together in github.com/nuphos/nuphos, and every release is published there.

Every part of Nuphos can run on your own infrastructure. On the sign-in screen, select Self-hosted? Set API endpoint to point Desktop or the iOS app at your server, or Use Nuphos Cloud to switch back. New workspaces get a two-step agent setup: local agents first, then an optional Cloud agent on Nuphos Cloud or self-hosted on Zeabur, Railway or Docker Compose. Operators will find images and upgrade steps in each release's notes.

Grok Build, Google Antigravity and OpenCode

Three new agents are available as Nuphos-managed or self-hosted Cloud agents:

Grok Build (xAI) signs in with a device code and shows its subscription usage.
Google Antigravity signs in with your Google account.
OpenCode walks you through its own sign-in: pick a model provider, then enter an API key, approve a device code, or paste a code.

Models are now picked per conversation from the list the agent itself offers, even before the first message. The per-agent default model setting has been removed. Claude Code also gains Claude Haiku 5.5.

Share is now a card with the session link, its participants, and a searchable list of teammates. Each session has its own General access: Only people invited, Everyone in the team · Can view, or Everyone in the team · Can view and reply. Invited people are Can view, Can reply or Can manage; managers can also move the session to another Nuphos-managed agent and change its credentials.

New sessions start as Only people invited. Existing sessions, and those from Slack, Discord, Lark and Triggers, stay open to the team.

Agents that follow your work

Agents can link GitHub pull requests and Linear issues to a session. They show under the session title, and a linked pull request wakes the session on reviews, comments, CI results and merges.
Agents can open a terminal in the conversation's dock and work in the same shell you see.
Files or images sent while the agent is working now steer the running turn instead of waiting.
An agent can hand a bounded task, such as waiting for PR checks, to a separate visible conversation.

Nuphos in your terminal

The new nuphos CLI opens conversations in a full-screen terminal UI. You can create a team, add and sign in a Cloud agent, and pick a model with /model, all without the desktop app. nuphos agent runs this computer's Claude Code and Codex as local agents. Update with nuphos update.
