Joplin vs Radarr

Joplin vs Radarr: at a glance
What is Joplin?
Joplin fixes 50+ server security issues found in a Claude-assisted review of Joplin Cloud.
Joplin added AI in 3.7 (chat, semantic search, MCP), all opt-in, and has since named Mistral's EU endpoint as the provider behind Joplin Cloud AI. Its November 2 post reports a full review of Joplin Server, which also runs Joplin Cloud, done with Claude through Anthropic's Cyber Verification Program: no critical findings, but more than 50 high, medium and lower issues fixed. Self-hosters need 3.7.4 or later, which changes LDAP and SAML sign-in behavior.
What is Radarr?
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
Radarr's 7.0 pre-release line is on its second build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports. 7.0.1 follows with media info that lists every audio and subtitle stream, full Transmission label support and clearer import-failure messages. The main branch is still on 6.4.4.
Joplin vs Radarr: editorial side-by-side
Joplin
5.0COLLAB
Joplin fixes 50+ server security issues found in a Claude-assisted review of Joplin Cloud.
◆ Current state
Joplin added AI in 3.7 (chat, semantic search, MCP), all opt-in, and has since named Mistral's EU endpoint as the provider behind Joplin Cloud AI. Its November 2 post reports a full review of Joplin Server, which also runs Joplin Cloud, done with Claude through Anthropic's Cyber Verification Program: no critical findings, but more than 50 high, medium and lower issues fixed. Self-hosters need 3.7.4 or later, which changes LDAP and SAML sign-in behavior.
◆ Where it's heading
Joplin's recent posts are about trust: privacy terms for AI, a named data processor, and now an audited server. The product is positioning its cloud as safe to put notes in while feature releases stay on a roughly four-month cycle.
◆ Prediction
The next feature release, around 3.8, would fit the four-month cadence in early 2027; the security post suggests more server-side hardening will land in point releases before then.
Radarr
5.0COLLAB
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
◆ Current state
Radarr's 7.0 pre-release line is on its second build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports. 7.0.1 follows with media info that lists every audio and subtitle stream, full Transmission label support and clearer import-failure messages. The main branch is still on 6.4.4.
◆ Where it's heading
The 7.0 cycle pairs a platform upgrade with deeper file-level detail: media info, import diagnostics and download-client labels. The media info migration was split into batches to avoid running out of memory, which shows the team is hardening the upgrade path for large libraries before a stable release.
◆ Prediction
More 7.0.x pre-release builds with import and media info fixes are likely before 7.0 reaches the main branch; the entries do not show a date for that promotion.
