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 is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.

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
7.5COMMSCOLLAB
Slack is quietly rebuilding itself as a runtime for third-party agents.
◆ Current state
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
◆ Where it's heading
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
◆ Prediction
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
