Pydio Cells vs Readwise
A side-by-side editorial comparison of Pydio Cells and Readwise — release velocity, themes, recent moves, and the top alternatives to consider.
Pydio Cells vs Readwise: at a glance
What is Pydio Cells?
Cells 5.1 gives tag values their own access policies, and 5.1.1 makes them hold up.
v5.1.0 added access policies for Entity Values, the metadata store v5 introduced, with dedicated CRUD endpoints and an admin flag that stops end users adding new tag values. v5.1.1 follows five weeks later with fixes for that same feature: the restrict-values toggle on TagCloud now switches off, and policy-group caching is safe under concurrent access. The 4.4 branch still gets occasional maintenance releases alongside v5.
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.

Pydio Cells
5.0COLLAB
Cells 5.1 gives tag values their own access policies, and 5.1.1 makes them hold up.
◆ Current state
v5.1.0 added access policies for Entity Values, the metadata store v5 introduced, with dedicated CRUD endpoints and an admin flag that stops end users adding new tag values. v5.1.1 follows five weeks later with fixes for that same feature: the restrict-values toggle on TagCloud now switches off, and policy-group caching is safe under concurrent access. The 4.4 branch still gets occasional maintenance releases alongside v5.
◆ Where it's heading
The v5 line has moved from post-launch stabilisation to filling out its metadata and permissions model, and each feature release is followed by a hardening pass on the same code. The releases point toward admins getting finer control over metadata, not toward new end-user features.
◆ Prediction
Expect more 5.1.x patches on policy and metadata performance before a 5.2 adds the next admin control. The entries do not show when the 4.4 branch will stop getting maintenance releases.
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.
