What is Slack?
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
What is SoundBase?
Soundbase layers AI Autopilot and continuous Health Check onto RF coordination — and adds an Enterprise Portal.
Soundbase is layering automation and AI on top of its core RF frequency-coordination engine for live audio. Health Check now runs continuously in the background flagging conflicts, exclusions, spacing and IMD issues. The new Soundbase Assistant introduced Autopilot (Beta) for smart setup, and the Enterprise Portal added advanced search across machine/user/email plus a redesigned user table — signs of bigger-customer maturity.
Slack vs SoundBase: editorial side-by-side
Slack
6.3COMMSCOLLAB
Slack now hosts any A2A agent without Slack-specific code.
◆ Current state
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
◆ Where it's heading
Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
◆ Prediction
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.
SoundBase
0.0COLLAB
Soundbase layers AI Autopilot and continuous Health Check onto RF coordination — and adds an Enterprise Portal.
◆ Current state
Soundbase is layering automation and AI on top of its core RF frequency-coordination engine for live audio. Health Check now runs continuously in the background flagging conflicts, exclusions, spacing and IMD issues. The new Soundbase Assistant introduced Autopilot (Beta) for smart setup, and the Enterprise Portal added advanced search across machine/user/email plus a redesigned user table — signs of bigger-customer maturity.
◆ Where it's heading
The product is moving from 'better calculation engine' to 'background-running coordination intelligence' — Health Check, Autopilot and the new calculation engine all pull users out of manual frequency-by-frequency tuning. Equipment profile coverage keeps expanding (Sennheiser, Wisycom, Comtek), positioning Soundbase as the broadest cross-vendor RF tool, while Enterprise Portal investment hints at top-down adoption inside touring and broadcast orgs.
◆ Prediction
Expect Autopilot to graduate out of beta with a paid tier, deeper integration with live scan-data hardware (RF Venue Spectrum Recorder, Wisycom), and continued vendor profile expansion. Mobile-first surfaces would be the next obvious gap.
