Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of SimpleX Chat and WATI — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Wati's feed is all WhatsApp marketing content, not product releases
The tracked feed for Wati is a content-marketing blog, not a product changelog: every recent entry is an SEO-oriented article about WhatsApp Business API, Meta Business Agent, drip campaigns, and voice agents rather than a shipped change to the Wati platform. What signal does exist points to Wati positioning itself around Meta's new Business Agent (repeatedly arguing it complements rather than replaces the WhatsApp Business API) and around WhatsApp native voice/calling. No actual version, capability, or pricing change is observable in these entries.

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.

No actual version, capability, or pricing change is observable in these entries.
Editorially, Wati is leaning hard into two narratives: defending the WhatsApp Business API's value against Meta's free Business Agent, and pushing WhatsApp-native voice/AI-agent calling. These are marketing themes, not release evidence, so trajectory on the product itself is unclear from this feed. The recurring Meta-Business-Agent framing suggests Wati sees Meta's move as the competitive story it most needs to shape for customers.
The feed is a blog, not a changelog, so a grounded product-move prediction isn't supported by these entries; expect continued content cadence around Meta Business Agent and WhatsApp voice rather than observable product changes here.
