The open source Grok Bot alternative
Always-on agents that run on the Claude Code or Codex subscription you already pay for, on a managed cloud computer or your own machine, in a workspace your whole team can join.
What is Grok Bot?
Grok Bot is xAI’s agent product, launched in beta on August 11, 2026. Bots are AI teammates that remember your conversations and share an always-on cloud computer with browser and terminal access, so they keep working while you’re away and come back when something needs your approval. It is included with eligible paid SuperGrok and Cursor plans.
Why people look for an open alternative
Use the models you already pay for
Many teams already pay for Claude or ChatGPT and want their agents to use those subscriptions instead of buying another one.
Own the code and the data
An open source workspace can be read, audited and changed. Your transcripts, memory and connected accounts don’t have to live only in one vendor’s closed service.
Run it where you want
Some work belongs on a managed cloud computer, some on a server you own, and some on your laptop. Self-hosting is an option when the data can’t leave your infrastructure.
What Nuphos gives you
Bots that keep working
Give a Bot a name and a face and chat with it one-on-one. On a cloud computer or a server you keep running, its turn continues after you close your laptop, and you can pick it up from the iOS app.
Your Claude Code or Codex subscription
Each runtime signs in with your own Claude or ChatGPT account, so inference is billed by that provider. Nuphos doesn’t resell model usage. OpenCode, Grok Build and Antigravity runtimes are available too.
Managed cloud, remote or local
Run on a cloud computer Nuphos manages for your team, a machine you own, or this computer. Move a conversation between them and it keeps going.
Multiplayer by default
A session is a room. Invite teammates into a running conversation, put people and Bots in the same group chat, and steer the agent together. One step adds the agent to Slack or Discord.
Triggers and connectors
Start a turn from a schedule, a webhook or a database alert. Connect GitHub, Linear, Slack, Grafana, cloud accounts and more once, and every agent on the team can use them.
Shared memory and skills
Memory is built in across agents, sessions and teammates, with nothing to install. Skills are shared and synced across the team.

Grok Bot details are from xAI’s posts Introducing Grok Bot (August 11, 2026) and Grok Bot is now included with more plans (August 26, 2026). Check x.ai for current plans.
Grok Bot is the simpler choice if you want a fully hosted product from xAI and like teaching a Bot by having it follow along while you work. Nuphos fits better when you want to choose where agents run, keep using Claude Code or Codex, read the source, and share the work with your team.

From each project’s own README, November 2026; Rakazo’s hosted plan, subscription sign-in and shared learning are from rakazo.com. “?” means the project doesn’t say. Projects change quickly; check their repositories for current details.
Rakazo and OpenMausBot also let you use a subscription you already pay for, and Rakazo also offers a hosted plan. What sets Nuphos apart is teammates working with the agent in the same live session, on a managed cloud runtime or your own machines. The others lead elsewhere: Hermes Agent reaches more chat apps and writes its own skills, OpenBot has fine-grained action policies, Rakazo has a web app and more sandbox providers, and OpenMausBot gives each Bot a local VM and installs whole teams from a template.
