Delta Chat
DeltaChat keeps shedding its email-client past to become a full messenger.
A side-by-side editorial comparison of SlickText and Rocket.Chat — release velocity, themes, recent moves, and the top alternatives to consider.
SlickText adds RCS, pushing past plain SMS into verified, branded business messaging.
SlickText runs a heavy SEO content engine — templates, listicles, vertical guides, awards posts — but the substantive product move is the addition of basic RCS messaging, bringing verified business identity and richer formatting to a platform built on plain SMS. Everything else in the recent feed is marketing and category positioning.
Rocket.Chat grinds through the 8.7 release-candidate line, with a server-side OAuth and phishing-resistant MFA push landing in the mix.
Rocket.Chat's GitHub feed is a stream of release candidates — 8.7.0-rc.x on top of a just-closed 8.6.0-rc line. Most are patch bumps and dependency rolls, but the 8.7.0-rc.0 minor carries real security work: a fully server-side OAuth flow and phishing-resistant MFA, plus session-management refinements. The open-source, self-hosted team-chat cadence is steady and RC-heavy.

Everything else in the recent feed is marketing and category positioning.
The product is broadening from SMS-only toward a multi-format messaging stack where channel trust and branding matter. RCS gives SlickText a credible answer to the deliverability and impersonation problems that plain text marketing can't solve on its own, and slots it against enterprise rivals it keeps writing comparison content about.
Expect RCS to move from 'basic' to feature-complete — branded sender profiles, rich cards, and read receipts — and to become a headline differentiator in the comparison content SlickText already publishes against Attentive and EZ Texting.
Rocket.Chat's GitHub feed is a stream of release candidates — 8.7.0-rc.x on top of a just-closed 8.6.0-rc line.

The open-source, self-hosted team-chat cadence is steady and RC-heavy.
The 8.6-to-8.7 arc leans on hardening: SSRF fixes, federation message-sync repairs, and now moving OAuth authentication entirely to the server to reduce token-exposure risk. Direction is security and reliability maturation of an already broad platform rather than net-new surface.
Expect 8.7.0 to reach a stable release once the rc line settles, carrying the server-side OAuth and MFA improvements as the headline security items.
