Vellum for teams: the open-source alternative a company shares

Vellum fits one person; a company needs a shared system

Vellum is a personal assistant. Its own homepage describes an assistant you name and shape, that remembers you across conversations and lives on your machine or in Vellum Cloud. That design serves one person, and Vellum's cloud plans are priced for one assistant. A company has a different problem: several people, one set of tools, and work that has to survive a person leaving.

The team dimensions a personal assistant leaves open

Three things separate a personal assistant like Vellum from a company system: where the shared context lives, which tool each agent may touch, and who reviews the work before it lands. Kortix is the open-source AI Operating System, and it answers all three in one place. Its agents, skills, company memory, and connectors live in one git repo the team owns.

Shared context you can grep, diff and audit

Kortix keeps company memory as files in the project repo. A new member gets the same context as everyone else by cloning the repo, and a change to how a job runs shows up as a diff. Vellum keeps memory with the one person who owns the assistant, on their machine or in their cloud.

Permissions, isolation and review are files you can read

Kortix gives each session its own isolated sandbox and its own branch, and it sets each tool call to Allow, Ask or Block. Approval gates you set. Off until you set them. You keep the rules in kortix.yaml, so an agent's reach is reviewed like code. Session work reaches main through a change request a person approves. The shape fits in one file:

kortix_version: 2default_agent: kortixagents:  support-triage:    file: agents/support-triage.md    connectors: alltriggers:  - slug: weekly-digest    type: cron    cron: "0 0 9 * * 1-5"    prompt: Summarize yesterday's support tickets and open a change request.

Running the open-source platform for your team

Kortix runs on Kortix Cloud, in your VPC, or on your own on-prem network, and self-host is free. The self-hosting guide walks through the platform on a server you control. When you would rather not run a server, the managed cloud charges per seat, so a team grows by adding people instead of standing up another assistant.
