CommaFeed vs Readwise: at a glance
What is CommaFeed?
After a summer of security patches, CommaFeed 7.4 moves feed fetching to HTTP/2.
CommaFeed's 7.x line spent July and August on security fixes, one per patch release: an image-proxy SSRF, javascript: URLs filtered at parse time, local address blocking on by default, Host header injection in password recovery, and a cross-user disclosure via starring and tagging. Version 7.4.0 on October 19 turned back to fetching, with HTTP/2, more default headers so fewer servers reject it, and tighter iframe sandboxing; 7.4.1 three days later fixed entries being marked read on scroll-back and added an HTTP/2 timeout.
What is Readwise?
Readwise launches Books, its own ebook store and reading app, a week after unbundling.
Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.

After a summer of security patches, CommaFeed 7.4 moves feed fetching to HTTP/2.
◆ Current state
CommaFeed's 7.x line spent July and August on security fixes, one per patch release: an image-proxy SSRF, javascript: URLs filtered at parse time, local address blocking on by default, Host header injection in password recovery, and a cross-user disclosure via starring and tagging. Version 7.4.0 on October 19 turned back to fetching, with HTTP/2, more default headers so fewer servers reject it, and tighter iframe sandboxing; 7.4.1 three days later fixed entries being marked read on scroll-back and added an HTTP/2 timeout.
◆ Where it's heading
With the security backlog cleared, releases are shifting to feed compatibility and reading behavior. The quick 7.4.1 follow-up suggests the HTTP/2 client is still settling.
◆ Prediction
Further 7.4.x patches for the HTTP/2 client are the likeliest next entries.
Readwise
6.3COLLAB
Readwise launches Books, its own ebook store and reading app, a week after unbundling.
◆ Current state
Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.
◆ Where it's heading
Readwise is moving from a layer on top of other people's reading apps to owning the purchase and the reading itself. The unbundle, the free Books app and the shared MCP server point to separate entry products that all feed the same account. Reader keeps its weekly cadence of TTS, transcript and parsing work underneath.
◆ Prediction
Expect weekly Books fixes and Kindle-import work, and a move from invite-only to open signup if the store holds up.
