Element iOS vs Slack
A side-by-side editorial comparison of Element iOS and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Element iOS vs Slack: at a glance
What is Element iOS?
Element Classic now asks its own users to move to Element X, if their server opts in.
Element iOS, renamed Element Classic in late 2025, has been in maintenance with single-change releases weeks or months apart. After the device-verification banner saga closed in June, 1.11.41 on September 24 adds a room-list banner inviting users to migrate to Element X. Homeservers switch it on through their Well Known file and can set the text, button and target app.
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 iOS vs Slack: editorial side-by-side
Element iOS
0.0COMMS
Element Classic now asks its own users to move to Element X, if their server opts in.
◆ Current state
Element iOS, renamed Element Classic in late 2025, has been in maintenance with single-change releases weeks or months apart. After the device-verification banner saga closed in June, 1.11.41 on September 24 adds a room-list banner inviting users to migrate to Element X. Homeservers switch it on through their Well Known file and can set the text, button and target app.
◆ Where it's heading
The legacy client is being wound down deliberately, with homeserver operators controlling when their users are nudged to the new app. Releases will likely stay rare and focused on migration and security.
◆ Prediction
Expect the migration banner to become more prominent or default-on in a later release; an end-of-support date is not visible in the entries.
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.
