Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of Revolt and SimpleX Chat — release velocity, themes, recent moves, and the top alternatives to consider.
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.
SimpleX builds out channels in the v7.0 beta, layering broadcast roles onto its no-identifiers messenger
SimpleX Chat is mid-way through its v7.0 beta cycle, and the throughline is channels: web previews to read posts before joining, owner-managed relays, promotable subscriber-to-contributor roles, and supporter badges. Interleaved with the feature betas are armv7a build tags that are merge-only and carry no release content.

With only a single changelog entry available, the broader release cadence isn't observable from this data.
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.
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.
SimpleX Chat is mid-way through its v7.0 beta cycle, and the throughline is channels: web previews to read posts before joining, owner-managed relays, promotable subscriber-to-contributor roles, and supporter badges. Interleaved with the feature betas are armv7a build tags that are merge-only and carry no release content.
The privacy-first, no-user-identifiers messenger is adding a broadcast/community layer on top of its 1:1 and group foundations. v7.0 reads as SimpleX's push toward public channels as a first-class surface, with the role system (owners, contributors, subscribers, supporters) and relay management being the scaffolding for larger, semi-public communities while keeping the metadata-minimal model.
Expect v7.0 to stabilize out of beta with channels fully fleshed out, and the supporter-badge work to hint at a creator/monetization angle for channel owners.
