CryptPad vs Prowlarr
A side-by-side editorial comparison of CryptPad and Prowlarr — release velocity, themes, recent moves, and the top alternatives to consider.
CryptPad vs Prowlarr: at a glance
What is CryptPad?
CryptPad rebuilt its server and swapped its office engine; now it is patching the fallout.
CryptPad just shipped its largest architectural change in years: a rewritten server published as a standalone npm package, and office apps moved from OnlyOffice to Euro-Office 9.3. Three weeks later a fix release followed with team-deletion, sharing and eviction-script repairs plus security fixes rated up to CVSS 7.3. The product is an end-to-end encrypted suite whose release rhythm is seasonal: one feature drop, then one or two fix releases.
What is Prowlarr?
Prowlarr's 3.0 pre-release keeps API keys out of logs and speeds up JSON parsing.
Prowlarr, the indexer manager for the *arr apps, is testing a 3.0 line on its develop branch. 3.0.0 moved the runtime to .NET 10 and Node 24, raised the Postgres minimum to 15 and added ZFS reflink support. 3.0.1 follows with a log fix that scrubs API keys in JSON-escaped query strings and a move to byte-level JSON deserialization.

CryptPad
6.3COLLAB
CryptPad rebuilt its server and swapped its office engine; now it is patching the fallout.
◆ Current state
CryptPad just shipped its largest architectural change in years: a rewritten server published as a standalone npm package, and office apps moved from OnlyOffice to Euro-Office 9.3. Three weeks later a fix release followed with team-deletion, sharing and eviction-script repairs plus security fixes rated up to CVSS 7.3. The product is an end-to-end encrypted suite whose release rhythm is seasonal: one feature drop, then one or two fix releases.
◆ Where it's heading
The office suite is the recurring pressure point: nearly every release since 2025 carries OnlyOffice corruption, history or pinning fixes, and the Euro-Office swap is the team taking ownership of that dependency. Splitting the server into its own package points toward easier self-hosting and embedding, which matches the openDesk integration builds and Integration API work seen earlier in the year.
◆ Prediction
Expect another fix release within weeks addressing new-server and Euro-Office edge cases, then a winter feature release built on the new server. Whether the server package gets third-party adoption is not visible from these entries.
Prowlarr
5.0COLLAB
Prowlarr's 3.0 pre-release keeps API keys out of logs and speeds up JSON parsing.
◆ Current state
Prowlarr, the indexer manager for the *arr apps, is testing a 3.0 line on its develop branch. 3.0.0 moved the runtime to .NET 10 and Node 24, raised the Postgres minimum to 15 and added ZFS reflink support. 3.0.1 follows with a log fix that scrubs API keys in JSON-escaped query strings and a move to byte-level JSON deserialization.
◆ Where it's heading
The 3.0 cycle is a platform refresh rather than a feature release, and the follow-up builds are tightening it before it reaches stable. The pattern from 2.6 and 2.7, a pre-release then a stable build days or weeks later, suggests 3.0 will land on master once these fixes settle.
◆ Prediction
A stable 3.0 release on the master branch is the likely next step, carrying the .NET 10 and Postgres 15 requirements to all users.
