Joplin vs Prowlarr: 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 Prowlarr?
Prowlarr 3.0 pre-release moves to .NET 10 and requires Postgres 15
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. The 2.6–2.7 line added Trusted Networks, hostname validation and wildcard IPs in Allowed Hosts. A 3.0.0 pre-release on the develop branch now moves the runtime to .NET 10 and Node 24, raises the minimum Postgres version to 15 and adds reflink support for ZFS.

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.
Prowlarr
5.0COLLAB
Prowlarr 3.0 pre-release moves to .NET 10 and requires Postgres 15
◆ Current state
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. The 2.6–2.7 line added Trusted Networks, hostname validation and wildcard IPs in Allowed Hosts. A 3.0.0 pre-release on the develop branch now moves the runtime to .NET 10 and Node 24, raises the minimum Postgres version to 15 and adds reflink support for ZFS.
◆ Where it's heading
The project is pairing small indexer fixes on the stable branch with a platform refresh on develop. The 3.0 work is mostly runtime and database floor changes rather than new user features, so the jump is about keeping the stack current.
◆ Prediction
Expect further 3.0 pre-releases before a stable 3.0, with Postgres users below version 15 needing to upgrade first; the entries do not show a release date.
