Revolt vs Slack
A side-by-side editorial comparison of Revolt and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Revolt vs Slack: at a glance
What is Revolt?
Revolt swaps Tenor for its own Gifbox, pulling GIF delivery in-house.
Revolt is an open-source, self-hostable chat platform competing in the Discord-alternative space. The one visible release, v0.13.8, replaces Tenor (Google's GIF service) with Gifbox, a GIF platform the project now runs itself. With only a single changelog entry available, the broader release cadence isn't observable from this data.
What is Slack?
Slack pushes Block Kit toward data-rich UIs while wiring Slackbot into the MCP agent ecosystem.
Slack's platform team is shipping on two fronts. It is extending Block Kit with data-oriented blocks (data table in May, data visualization and a container block in June) and it is connecting Slackbot to the Model Context Protocol, first with server-side MCP tools and now a Slackbot MCP Client. Steady CLI (v4.1 through v4.3) and SDK point releases show an actively maintained developer platform underneath.

Revolt
2.5COMMS
Revolt swaps Tenor for its own Gifbox, pulling GIF delivery in-house.
◆ Current state
Revolt is an open-source, self-hostable chat platform competing in the Discord-alternative space. The one visible release, v0.13.8, replaces Tenor (Google's GIF service) with Gifbox, a GIF platform the project now runs itself. With only a single changelog entry available, the broader release cadence isn't observable from this data.
◆ Where it's heading
Owning the GIF layer instead of leaning on Tenor fits the pattern of a self-hosting-first project reducing third-party and Google dependencies. It points toward more of the messaging stack being brought under the project's own control over time.
◆ Prediction
Expect follow-up work hardening Gifbox (search quality, content moderation, self-host configuration). With only one entry visible, anything beyond that is unclear from the available data.
Slack
6.3COMMSCOLLAB
Slack pushes Block Kit toward data-rich UIs while wiring Slackbot into the MCP agent ecosystem.
◆ Current state
Slack's platform team is shipping on two fronts. It is extending Block Kit with data-oriented blocks (data table in May, data visualization and a container block in June) and it is connecting Slackbot to the Model Context Protocol, first with server-side MCP tools and now a Slackbot MCP Client. Steady CLI (v4.1 through v4.3) and SDK point releases show an actively maintained developer platform underneath.
◆ Where it's heading
The direction is Slack-as-surface for AI agents and richer in-app data display. On the agent side, May's Slack MCP server tools and June's Slackbot MCP Client build both halves of an MCP bridge — Slack hosting agents and Slackbot calling external tools. On the UI side, the run of data table, data visualization, and container blocks lets apps render structured data inline instead of dumping text into messages.
◆ Prediction
Expect more Block Kit data primitives and deeper MCP tooling — likely additional Slackbot MCP client capabilities or agent-oriented features surfacing through the next CLI and SDK releases.
