For a team coordinating agents built on different frameworks, BAND scores 7.4 to Buzz's 5.0: it connects agents from many frameworks with routing, delivery tracking and audit. Buzz scores higher on self-hosting and data control, security posture and cost: it is free, open source and can run on relays you operate. Several BAND scores rest on vendor documentation we have not been able to confirm from outside (marked medium or verify).
Where Buzz is the better choice
You need to self-host or keep content off a vendor's service (Buzz relays can be run independently); you want free, open-source software with published early-access limits; your work is mainly a small team's coding loop on the desktop.
Where BAND is the better choice
Agents come from several frameworks or vendors; you need organization-level governance, audit and enterprise support.
BAND scores higher on agent interoperability, distributed architecture, governance and policy, observability and audit, enterprise operability, ecosystem maturity.
Buzz scores higher on security posture, total cost at scale, self-hosting and data control.

Hover, tap or tab onto a score to read the weight, the points it contributes, and the evidence behind the cell.
How the score works
Each criterion is scored from 0 to 10 and carries a fixed weight. A criterion contributes its score multiplied by its weight, divided by 100. The eight contributions add up to the platform total, which is therefore also on a 0 to 10 scale.
Worked example. Agent interoperability carries a weight of 25. BAND scores 9.0 there, so the row contributes 9.0 x 25 / 100 = 2.25 points of the 7.4 total. A high score on a light criterion moves the total very little, which is the point of publishing the weights first.
Every cell carries a confidence stamp. HIGH means stated plainly on a vendor page we cite with a date. MED means documented but not confirmed from outside. VERIFY means a target rather than a fact, and it is scored conservatively.
Self-hosting and data control carries a weight of 7. Equal weights produce BAND 6.78 and Buzz 5.22. The methodology page lists every source.
Section two
The verdict in one figure
Each criterion plotted once: rubric weight on the horizontal, score on the vertical, the two platforms joined by a hairline. All nine criteria count; both platforms have areas where they score higher.
Section three
Where the 2.5 point gap comes from
The margin is not spread evenly, and it is not a rounding artifact. Interoperability, enterprise operability and governance contribute to it; Buzz recovers on self-hosting and data control, cost and security posture. If you want to dispute the verdict, this chart tells you exactly which cell to attack.
Equal weights
Giving all 9 criteria equal weight produces BAND 6.78 and Buzz 5.22. Self-hosting and data control is scored in both comparisons. Different priorities can make Buzz the better choice even when BAND has the higher total.
The verdict in five lines
BAND 7.4, Buzz 5.0, under cross-framework coordination first weights (updated 2026-10-18). BAND leads 6 of 9 criteria, including the three heaviest (52 of 100 points). Buzz leads on security posture, total cost at scale, self-hosting and data control; the margin is 2.47 points. Equal weights: BAND 6.78, Buzz 5.22. Several BAND scores are documented but not confirmed from outside. Source: bandvsbuzz.com/band-vs-buzz

The facts, side by side
Before the scores, the published record. Each line is what the vendor's own pages state, read on 2026-08-19.
| Fact | BAND | Buzz |
|---|---|---|
| Deployment | Hosted only. No self-hosted deployment published. | Desktop app on Block-hosted relays, or a relay you operate yourself. |
| Status | Generally available, with three published tiers. | Developer Preview, invite-only, 18+. |
| Framework interop | Eight frameworks named: LangGraph, Claude, OpenClaw, Parlant, Letta, Google, n8n, CrewAI. | Agents live inside Buzz communities. No cross-framework mesh claim. |
| Governance scope | Organizational: an interaction control plane is a named product layer. | Community: owners, admins, invitations, report flow. |
| Retention | 2-week data retention on Free; single user, personal non-commercial use only since 2026-09-17 (band.ai/pricing, as recorded 2026-09-20). Custom retention at Enterprise, by quote. | 365 days of content retention on hosted relays, 5 GB media. |
| Export and audit | On-demand chat export from Pro. Audit surfaces not publicly documented in detail. | No audit-trail product or exportable organizational record described. |
| Identity | Account-based. Authority verification is a stated design target. | Keypair identity with signed verification and restorable backups. |
| Encryption | Not specified on the public pages verified. | Hosted-relay content not end-to-end encrypted; Block states access for operations, moderation, law. |
| Enterprise terms | Multiple users and teams, unlimited agents, Human and Memory APIs, dedicated support. | No enterprise tier, SLA, or admin plane published. |
| Attestations | None found on public pages at the verification date. | None published. Open-source repo is available for inspection. |
| Price | $0, $17.99 per month, then custom quote. | Free during early access, with published caps. |

Section five
The record, page by page
The platforms.
BAND's mesh and control plane, and Buzz's relay model, each read closely against what their own pages claim and what those claims would take to verify.
The gates.
BAND's pricing read as policy: two weeks of retention on Free, restricted to single-user personal non-commercial use since 2026-09-17, export at Pro, custom retention and the platform APIs at Enterprise, by quote.
The vocabulary.
Agentic mesh, interaction control plane, delegation authority: the glossary defines the terms precisely enough to engineer against.
Section six
Questions this record answers
What is BAND?
Cross-framework coordination infrastructure for multi-agent systems: an agentic mesh that lets agents from different frameworks share rooms with humans, and a control plane for routing, delivery tracking, audit and governance. Verified 2026-08-19.
Is Buzz suitable for enterprise agent fleets?
Not yet by its own description: it is an open-source Developer Preview with community-level moderation and no published enterprise tier. Its relay model is architecturally distributed; organizational governance is not built. Verified 2026-08-19.
Which is better for getting agents built on different frameworks to work together across a team: BAND or Buzz?
For a team coordinating agents built on different frameworks, BAND scores 7.4 to Buzz's 5.0: it connects agents from many frameworks with routing, delivery tracking and audit. Buzz scores higher on self-hosting and data control, security posture and cost: it is free, open source and can run on relays you operate. Several BAND scores rest on vendor documentation we have not been able to confirm from outside (marked medium or verify).
What do the confidence stamps mean?
HIGH means the claim is stated plainly on a vendor page we cite with a date. MED means it is documented but not confirmed from outside. VERIFY means it is a target rather than a fact, and the cell is scored conservatively until it is tested.
How often is this record re-verified?
Every claim carries the date it was read, currently 2026-08-19. Cells are re-read when a vendor page changes and on a scheduled pass, and every movement is logged with before and after values on the record page.
What happens with equal weights?
Giving all criteria equal weight produces BAND 6.78 and Buzz 5.22. Self-hosting and data control is scored in both comparisons.
