Element vs Slack
A side-by-side editorial comparison of Element and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Element vs Slack: at a glance
What is Element?
Element ships MatrixRTC calls and starts moving its web client onto Rust.
October was Element's busiest stretch in this window. MatrixRTC, a decentralised, end-to-end encrypted multiparty call protocol, arrived; five public sector organisations showed cross-border federation at the Matrix Conference; and openDesk now deploys Element Server Suite directly from Element. Element Web has also started moving to the Matrix Rust SDK, one component at a time.
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.
Element vs Slack: editorial side-by-side
Element
5.0COMMS
Element ships MatrixRTC calls and starts moving its web client onto Rust.
◆ Current state
October was Element's busiest stretch in this window. MatrixRTC, a decentralised, end-to-end encrypted multiparty call protocol, arrived; five public sector organisations showed cross-border federation at the Matrix Conference; and openDesk now deploys Element Server Suite directly from Element. Element Web has also started moving to the Matrix Rust SDK, one component at a time.
◆ Where it's heading
Element is closing the gaps between sovereign messaging and the tools it wants to replace. Calls were a large remaining hole, and Open Productivity, a joint venture with other openDesk vendors, adds a commercial route to businesses and critical infrastructure operators. The web migration brings the desktop client onto the same base as Element X.
◆ Prediction
Expect more government deployments built on the federation demo, and steady Element Web components moving to shared code. The incremental approach means no single release will mark the switch to Rust.
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.
