Best agent collaboration infrastructure, 2026
Which is better for getting agents built on different frameworks to work together across a team: BAND or Buzz?
Desk review · ProvisionalFor 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).
