CommaFeed vs Prowlarr: at a glance
What is CommaFeed?
CommaFeed is patching its way through the attack surface a self-hosted reader inherits
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
What is Prowlarr?
A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.
Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.

◆ Current state
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
◆ Where it's heading
Every release in this stretch closes a path where content or a request from outside the instance was trusted too far - feed URLs reaching internal addresses, proxied images, javascript: links, and now a header shaping an outbound email. That is the checklist of a project being run as a multi-user hosted service rather than a single-user tool, and it follows directly from the 7.0.0 decision to sandbox filter expressions. Feature work continues in parallel but is clearly the smaller half.
◆ Prediction
The remaining untrusted-input surfaces - OPML import and the feed fetcher's redirect handling - are the likely next targets. The pattern of shipping each fix as its own patch release should continue rather than batching them.
Prowlarr
5.0COLLAB
A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.
◆ Current state
Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.
◆ Where it's heading
The value being shipped is upkeep of the indexer catalogue — PreToMe categories, M-Team category updates, MyAnonamouse author name handling, IPTorrents query parameters. That is the actual product for an indexer manager, but it means the release history reads flat: no architectural change, no new integration surface, no shift in what Prowlarr does. Version numbers move faster than capability.
◆ Prediction
Expect the same rhythm — per-indexer definition fixes and dependency bumps cut every one to two weeks — with any notable change arriving as a small search or UI addition rather than a release theme.
