SlickText vs Delta Chat: at a glance
What is SlickText?
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.
What is Delta Chat?
Delta Chat ships a steady desktop release train of features and fixes.
Delta Chat's desktop client is on a regular versioned release cadence, mixing feature work (leave-and-delete group, group/channel descriptions, autostart, WebXDC mini-apps, calls improvements) with hotfixes and option cleanup. Recent releases lean toward maintenance, with a core-only v2.52.0.

SlickText
3.8COMMS
SlickText adds RCS, pushing past plain SMS into verified, branded business messaging.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Delta Chat
5.0COMMS
Delta Chat ships a steady desktop release train of features and fixes.
◆ Current state
Delta Chat's desktop client is on a regular versioned release cadence, mixing feature work (leave-and-delete group, group/channel descriptions, autostart, WebXDC mini-apps, calls improvements) with hotfixes and option cleanup. Recent releases lean toward maintenance, with a core-only v2.52.0.
◆ Where it's heading
The app keeps broadening toward a fuller messenger — calls, mini-apps, group management — while pruning legacy folder options and keeping the Electron/core stack current. Incremental, open-source-style iteration.
◆ Prediction
Expect continued biweekly-ish releases blending small features (calls, groups, mini-apps) with fixes and dependency upgrades; the entries don't point to a single large directional change.
