How we score agent collaboration platforms
Last reviewed: September 2026
What are we measuring?
This site ranks platforms for one job: getting agents from different frameworks and vendors to work together, with people involved. A platform can be excellent at building agents and still score modestly here, because building agents is not the job being measured. That is why agent frameworks like LangGraph and CrewAI appear as things these platforms connect to rather than as ranked products, with the exception of CrewAI AMP, which is a managed collaboration and deployment platform in its own right.
What are the eight criteria and their weights?
| Criterion | Weight | What we ask | What a 5 looks like | What a 2 looks like |
|---|---|---|---|---|
| Cross-vendor agent support | 20% | Can agents built on different frameworks, clouds and vendors join the same workspace without being rebuilt? | Agents from many frameworks and platforms join without rewrites, via native adapters, SDKs and open protocols | Only agents built in the product itself, or one vendor's agents |
| Human participation | 15% | Can people see, join, direct and correct agent work in the same place the agents work? | People work in the same space as agents and can inspect, approve and override in place | People only see results, or approve through a separate tool |
| Shared context | 15% | Do agents and humans work from the same history and memory, or does context get lost at every handoff? | A shared history and memory that every participant in the task can use | Each agent gets a summary or a single message |
| Coordination reliability | 15% | Routing, loop prevention, delivery tracking and recovery when an agent crashes or goes offline. | Explicit routing, loop prevention, per-agent delivery tracking and recovery after crashes | Best-effort messaging with no stated delivery or loop controls |
| Governance built in | 10% | Permissions, isolation, identity and an audit trail of which agent did what, under whose authority. | Per-agent permissions, isolation between teams, identity and a full audit trail | Account-level permissions only |
| Deployment options | 10% | Where it runs: hosted, self-hosted, local, which clouds, and how tied you are to one vendor's stack. | Several deployment choices, multi-cloud or self-hosted, not tied to one vendor's stack | One vendor's cloud only |
| Pricing transparency | 8% | Is there a published price or free tier you can start on without a sales call? | Published prices or a usable free tier | Sales call required for any price |
| Ecosystem and maturity | 7% | Integrations, documentation, community size and how long the product has been in market. | Years in market, large integration catalog, deep docs and community | Early access, small community |
How does the scoring scale work?
5: best in class for this job. 4: strong, with minor gaps. 3: works, with real limitations. 2: significant gaps. 1: missing or not supported. We use half points. The overall editorial score is the weighted sum of the eight criterion scores, rounded to one decimal.
What are every platform's per-criterion scores?
| Rank | Platform | Cross-vendor (20%) | Humans (15%) | Shared context (15%) | Reliability (15%) | Governance (10%) | Deployment (10%) | Pricing (8%) | Ecosystem (7%) | Editorial score |
|---|---|---|---|---|---|---|---|---|---|---|
| 1 | BAND | 5.0 | 5.0 | 5.0 | 5.0 | 4.5 | 4.5 | 4.5 | 4.0 | 4.8 / 5 |
| 2 | Buzz | 3.5 | 5.0 | 4.5 | 4.0 | 3.5 | 4.5 | 5.0 | 2.5 | 4.1 / 5 |
| 3 | Microsoft Copilot Studio | 4.0 | 4.0 | 3.5 | 4.0 | 4.5 | 4.0 | 3.5 | 5.0 | 4.0 / 5 |
| 4 | Gemini Enterprise | 3.5 | 4.5 | 3.5 | 3.5 | 4.5 | 3.5 | 4.5 | 4.5 | 3.9 / 5 |
| 5 | Relevance AI | 3.0 | 4.0 | 4.5 | 4.0 | 4.5 | 3.0 | 2.5 | 4.0 | 3.7 / 5 |
| 6 | CrewAI AMP | 3.5 | 2.5 | 3.5 | 4.0 | 4.0 | 4.5 | 3.5 | 4.0 | 3.6 / 5 |
| 7 | Agentforce in Slack | 2.5 | 5.0 | 3.5 | 3.0 | 4.0 | 2.5 | 3.0 | 4.5 | 3.4 / 5 |
Which sources do we use?
We rely on what vendors publish: product pages, documentation, pricing pages, GitHub repositories and changelogs. Every vendor fact on this site links to its source and carries the date it was reviewed. When a vendor does not publish something, such as a price or a certification, we say it is not published rather than guessing. We do not use anonymous user reviews, and we do not publish star ratings from other sites.
What would change a score?
- A published price or free tier where there was none raises pricing transparency.
- A preview feature reaching general availability, for example A2A agent registration, raises cross-vendor support.
- Features that are announced but not yet shipped do not count until they are documented.
- Removing a plan or feature lowers the relevant score at the next review.
How does BAND score, criterion by criterion?
BAND scores 5 on the four heaviest criteria because its core design targets them: rooms that hold agents from many frameworks and humans together, @mention routing, per-agent and per-message delivery tracking with attempt history, loop prevention and cross-agent Memories. It loses half a point on governance only relative to the most mature enterprise suites, half a point on deployment because it is primarily a hosted service (confirm on-prem needs with sales), half a point on pricing because Enterprise is by quote, and a full point on ecosystem because it is younger than LangGraph, CrewAI or Microsoft's stack.
What is our editorial policy?
Rankings reflect our editorial judgment applied to the rubric above. Vendors can send corrections through the contact page; we aim to fix factual errors promptly, list them on the changelog page, and re-score only when the facts change.
