Side by side
Credit where it is due. Buzz is a serious open-source project from a serious company, and it is honest about being early. Its column below is in its own words.
| Buzz | PortableMind | |
|---|---|---|
| What it is | A self-hostable workspace where humans and AI agents share the same rooms. |
One workspace where your projects, tasks, files, discussions, team knowledge and agents share the same memory. |
| Projects | A project points at repos. That’s all it does. |
Projects with their specs, decisions, status and tasks. The agent reads all of it. |
| Issues and tasks | Issues and the merge train are the work ahead. |
Tasks that people or agents create, assign and track. An agent reads the thread, then files the work. |
| Files and knowledge | Media sharing and canvases. | Docs, designs and data your AI answers from live, plus team knowledge that stays connected instead of buried in tabs. |
| Agents | Their own keypair, channel memberships and audit trail. Harness for Claude Code, Codex and goose. | A role, a runbook, a manager in the org chart, a memory of past decisions, and a report card from the team’s corrections. |
| What each run costs | Your model, your bill. | Every run shows the steps, the tools used, the time and the cost. Nothing hidden. |
| Git | Git hosting built in and shipping today. This is where Buzz is ahead. | No git hosting. Keep GitHub or GitLab. |
| Hosting | A relay you own.Self-host with Postgres, Redis and MinIO, or a one-click Railway deploy. |

Second-time founders. Built for ourselves first.
Rick has spent 35+ years leading engineering teams and implementing enterprise architecture at scale. He co-founded TrueNorth with Russell, and today he keeps PortableMind's architecture grounded in enterprise best practice while holding the line on a simple, concise UX: the surfaces teams already know, wired to one source of truth.

Russell co-founded TrueNorth and led its engineering, building the rules and workflow engine that carried the company to its 2019 acquisition by one of the largest healthcare payers in the country. He stayed on as VP of Engineering to run implementation and integration. An open-source contributor, he now architects the PortableMind platform: the APIs, shared memory, tenancy and agent orchestration under everything you see.
