What is Contractbook?
Contractbook builds out admin and permissions plumbing for larger CLM deployments.
Contractbook's recent work is concentrated on team administration. User Groups landed in late January, followed by group-level company permissions in March that lets admins assign company-wide capabilities to entire groups at once. The earlier Users page consolidation set up the surface this all attaches to. A small branding addition — company logo on outbound emails — rounds out the window.
What is Rocket.Chat?
Rocket.Chat is methodically migrating off Meteor DDP toward a REST core
Rocket.Chat is mid-flight on its 8.5/8.6 release-candidate cycle. Beneath a steady stream of RC version bumps, the substantive work is a deliberate migration of client traffic from legacy Meteor DDP methods to REST endpoints, plus security hardening, federation fixes, and self-hostable building blocks like LibreTranslate auto-translation.

Contractbook
0.0COLLAB
Contractbook builds out admin and permissions plumbing for larger CLM deployments.
◆ Current state
Contractbook's recent work is concentrated on team administration. User Groups landed in late January, followed by group-level company permissions in March that lets admins assign company-wide capabilities to entire groups at once. The earlier Users page consolidation set up the surface this all attaches to. A small branding addition — company logo on outbound emails — rounds out the window.
◆ Where it's heading
The CLM is being shaped to support large companies with structured access policies, not just small teams sharing a workspace. Each release is removing per-user manual setup and replacing it with group-driven inheritance — a clear up-market move. Cadence is steady and tightly themed.
◆ Prediction
Expect SCIM/SSO depth to follow next, plus more granular role inheritance (per-Space, per-template). Audit logging or compliance-export features are a natural extension once group permissions stabilize.

Rocket.Chat is methodically migrating off Meteor DDP toward a REST core
◆ Current state
Rocket.Chat is mid-flight on its 8.5/8.6 release-candidate cycle. Beneath a steady stream of RC version bumps, the substantive work is a deliberate migration of client traffic from legacy Meteor DDP methods to REST endpoints, plus security hardening, federation fixes, and self-hostable building blocks like LibreTranslate auto-translation.
◆ Where it's heading
Two arcs run in parallel. The first is architectural: deprecating DDP methods (kept until 9.0.0) while routing clients through REST, which decouples the product from its Meteor heritage and makes external SDK/mobile clients first-class. The second is enterprise/sovereignty: on-prem translation, Virtru-backed ABAC, phishing-resistant OAuth — features aimed at self-hosting and regulated buyers.
◆ Prediction
Expect the DDP-to-REST migration to keep advancing endpoint by endpoint toward the 9.0.0 removal, and continued investment in self-hosted, governance-heavy capabilities that differentiate Rocket.Chat from SaaS-only chat competitors.
