Crisp vs Session: at a glance
What is Crisp?
Crisp ships RTM API events for verification and unread acknowledgement; the visible feed is docs-only and sparse.
Three new RTM API events shipped in a single batch on February 11: identity:verify:request, session:updated (with the verification list), and message:acknowledge:unread:send. Each lets integrators react in real time to verification or unread state without polling. The fourth entry is a truncated August 2025 version of the identity-verification event.
What is Session?
Session ships new app versions and node upgrades while Pro stays on hold.
Session's 2026 started with a funding scare, then community support restored its runway in June. Session Pro reached a beta in app stores in September before its launch was paused in October during talks with an allied privacy ecosystem. Since then the work is infrastructure: lighter Session Node software, an update on Protocol v2, and on November 9 new iOS, Android and Desktop releases with further voluntary node upgrades and progress on a unified client.
Crisp vs Session: editorial side-by-side
Crisp
0.0COMMS
Crisp ships RTM API events for verification and unread acknowledgement; the visible feed is docs-only and sparse.
◆ Current state
Three new RTM API events shipped in a single batch on February 11: identity:verify:request, session:updated (with the verification list), and message:acknowledge:unread:send. Each lets integrators react in real time to verification or unread state without polling. The fourth entry is a truncated August 2025 version of the identity-verification event.
◆ Where it's heading
What's visible is Crisp quietly extending its real-time API surface for integrators rather than shipping user-facing features. Whether the customer-messaging product itself is moving — AI assistance, channel additions, automations — isn't visible from this docs feed.
◆ Prediction
Expect more incremental RTM events as integrators request hooks. To read product direction we'd need to re-point the source to the release blog or product-news feed; this docs surface won't show user-visible changes.
Session
5.0COMMS
Session ships new app versions and node upgrades while Pro stays on hold.
◆ Current state
Session's 2026 started with a funding scare, then community support restored its runway in June. Session Pro reached a beta in app stores in September before its launch was paused in October during talks with an allied privacy ecosystem. Since then the work is infrastructure: lighter Session Node software, an update on Protocol v2, and on November 9 new iOS, Android and Desktop releases with further voluntary node upgrades and progress on a unified client.
◆ Where it's heading
With Pro paused, Session is spending its effort on the network and the client codebase: lighter nodes, Protocol v2 with forward secrecy and post-quantum encryption, and one client for all platforms. Monetization waits on the outside talks.
◆ Prediction
Expect a Protocol v2 alpha or the unified client to be the next visible release; Pro's timing depends on talks the entries do not detail.
