Five options, each checked at its source
The open-source CompanyOS
A Grok Bot alternative does the same job without one cloud computer shared by every bot. Kortix is the open-source CompanyOS: each session gets its own isolated machine and branch.
Open source · Any model, your own keys · Cloud, VPC or on-prem
One cloud computer per sessionIts own branch of the repositoryNothing shared with another sessionConnector logins and Kortix’s model keys never enter it.https://kortix.com/security
Session work reaches main through a change request. Merge is default-deny for agents.
x.ai’s own page says every Bot shares one persistent cloud computer and that isolation is per user, not per Bot, so the table asks where each option puts a session’s machine, its rules and its money.
| Criteria | our pick | ||||
|---|---|---|---|---|---|
| Open source | Yes. Read it, fork it, audit it. | No | Yes, Apache-2.0 | Yes, MIT | Yes, Apache-2.0 |
| What it is | An open-source CompanyOS: agents, skills and memory in one git repo | Bots that sign in to your tools and finish the work | Self-hosted bots with their own memory, routines and history | An assistant on your own computer, in your chat apps | A team of bots in a chat app sidebar |
| Where the work runs | Its own isolated sandbox, one per session | One persistent cloud computer shared by every Bot | Shared team computers, or isolated private computers | Your own computer, under one Gateway process | A cloud computer for each bot |
| How you reach it | Web, desktop, mobile, Slack, Microsoft Teams or email | Desktop app on macOS or Windows, or iOS | Web, Electron desktop, iOS and Android | Discord, iMessage, Slack, Teams and 20+ more | macOS, Windows and Ubuntu apps |
| Where its rules live | Files in a git repo you own | Inside the x.ai apps | In the app, per bot | Config on your own hardware | A local server and a data folder |
| How you pay | Free plan. $50 buys 5,000 credits; tiers to $50,000 a month | $30, $100 or $200 a month, included with Premium to Enterprise | Self-hosted, so the cost is the server and the models you run | No paid tier, hosted service or token | $15 a month Starter plan, up to 100 computer-hours, or self-hosted |
Rival cells repeat each project’s README as published in October 2026, and the Grok Bot cells come from x.ai and its docs. Check each vendor before you buy.
Three ordinary weeks in a small team, and the moment each one needs the computer to belong to the session rather than the account.
Two clients
A studio cannot run both accounts from the same browser profile. Each session has its own isolated machine and branch, so the logins one client’s work used are not the ones the next session opens.
| Client | Session | Computer | State |
|---|---|---|---|
| Acme | outreach-acme | cmp-4f2a | running |
| Northwind | inbox-northwind | cmp-9c1d | waiting |
| Northwind | invoice-northwind | cmp-9c1d | done |
3 sessions, 2 machines
Hand-off
The next person opens one project and sees every session, the diff and what is still open. Session work reaches main through a change request, and merge is default-deny for agents, so nothing lands while the owner is away.

Sign-off
Connector credentials are brokered server-side and never enter the machine, so the person who releases the send does not have to hand anybody a password to get it done.

Short answers, each one complete on its own so it can be read out of context.
Yes. Rakazo, OpenMausBot and OpenClaw are open-source bots you install and run yourself, and Kortix is the open-source CompanyOS for a team that wants the agents, their permissions and their memory in a git repo it owns. All four do the finished-work job x.ai’s Bots do, on computers their teams control.
Yes. OpenClaw, Rakazo and OpenMausBot are open source, so the software costs nothing on hardware you provide, with the model keys you already pay for. OpenMausBot also sells a hosted Starter plan at $15 a month. Kortix has a Free plan whose sessions need a model you connect, either your own provider key or a ChatGPT subscription.
No. Video generation is a separate Grok product, while Rakazo, OpenClaw, OpenMausBot and Kortix run agents that work inside your apps, and none of them makes video.
For chat on its own, Grok and ChatGPT are the direct answers, and among the open-source options Rakazo and OpenMausBot are the ones shaped like a chat app. A team that needs the agent work to land in a repo it reviews should start with Kortix.
Start with one job, one project and one person reviewing what lands.
