Rocket.Chat vs Delta Chat
A side-by-side editorial comparison of Rocket.Chat and Delta Chat — release velocity, themes, recent moves, and the top alternatives to consider.
Rocket.Chat vs Delta Chat: at a glance
What is Rocket.Chat?
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.
What is Delta Chat?
DeltaChat keeps shedding its email-client past to become a full messenger.
DeltaChat's desktop client is steadily converting from an email-based chat tool into a full-featured messenger. Recent releases layer on calls, channels, mini-apps, multi-transport, and proxies while stripping out legacy email affordances like OAuth and manual folder handling. The result is a client that increasingly hides its email plumbing behind mainstream-messenger conventions.

Rocket.Chat
5.0COMMS
Rocket.Chat grinds through the 8.7 release-candidate line, with a server-side OAuth and phishing-resistant MFA push landing in the mix.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Delta Chat
2.5COMMS
DeltaChat keeps shedding its email-client past to become a full messenger.
◆ Current state
DeltaChat's desktop client is steadily converting from an email-based chat tool into a full-featured messenger. Recent releases layer on calls, channels, mini-apps, multi-transport, and proxies while stripping out legacy email affordances like OAuth and manual folder handling. The result is a client that increasingly hides its email plumbing behind mainstream-messenger conventions.
◆ Where it's heading
The direction is consistent: lean on the chatmail relay model, remove classic-email options release by release, and match the UX users expect from Signal or Telegram. Recent versions add a command palette, message multiselect, keyboard navigation, and proxy status while deleting server-fetch and Show-Email settings. Each release trades another email-era affordance for a messenger-parity feature.
◆ Prediction
Expect continued removal of email-era settings and more messenger-parity work — likely deeper call and channel tooling plus command-palette expansion — rather than any return to email-client framing.
