Readwise vs Wiki.js
A side-by-side editorial comparison of Readwise and Wiki.js — release velocity, themes, recent moves, and the top alternatives to consider.
Readwise vs Wiki.js: at a glance
What is Readwise?
Two big swings in July and August, and since then Readwise has been paying the bill.
Readwise shipped a full mobile rewrite in late July and library-wide Ghostreader a fortnight later, and the weekly changelogs since have been almost entirely repair. The August 28 week is typical: thirteen fixes against five real improvements, spread across EPUB handling, chart and video embeds, Ghostreader chat on both mobile platforms, and Boox e-ink devices. The one consistent addition each week is parsing coverage for more publishers.
What is Wiki.js?
Wiki.js hits 3.0 beta while the 2.x branch enters security-only maintenance mode.
Wiki.js is in a split-track phase. The 2.x line is receiving security patches — including a privilege escalation fix and multiple auth hardening changes — but no new features. Development focus has moved to 3.x, which reached beta in September 2026 after an extended alpha period. The gap between the two tracks is widening: 2.x users are running maintained but frozen software.

Two big swings in July and August, and since then Readwise has been paying the bill.
◆ Current state
Readwise shipped a full mobile rewrite in late July and library-wide Ghostreader a fortnight later, and the weekly changelogs since have been almost entirely repair. The August 28 week is typical: thirteen fixes against five real improvements, spread across EPUB handling, chart and video embeds, Ghostreader chat on both mobile platforms, and Boox e-ink devices. The one consistent addition each week is parsing coverage for more publishers.
◆ Where it's heading
The fix list is a map of where the rewrite is still settling — pagination and layout stability on Android tablets, chat sheets and message sending on mobile, exports arriving with page CSS attached. Underneath that, small capabilities keep arriving quietly: Apple Books folder-EPUBs now upload, interactive charts render as linked images instead of an import notice, non-Latin titles survive the trip to Kindle. The company is broadening what it can ingest and export while stabilising what it rebuilt.
◆ Prediction
Expect the weekly cadence to hold with fixes still outnumbering additions, and the remaining Boox and Android tablet issues to keep appearing until the mobile rewrite fully settles.
Wiki.js
5.0COLLAB
Wiki.js hits 3.0 beta while the 2.x branch enters security-only maintenance mode.
◆ Current state
Wiki.js is in a split-track phase. The 2.x line is receiving security patches — including a privilege escalation fix and multiple auth hardening changes — but no new features. Development focus has moved to 3.x, which reached beta in September 2026 after an extended alpha period. The gap between the two tracks is widening: 2.x users are running maintained but frozen software.
◆ Where it's heading
3.x moving from alpha to beta is the key inflection point. Once stable, it will need to offer a viable migration path from 2.x — the wiki space has deep data lock-in (page trees, attachments, permissions), so the upgrade story is as important as the feature story. The 3.x alpha/beta cadence has been steady but slow, suggesting a deliberate rewrite rather than an incremental upgrade.
◆ Prediction
A 3.0 release candidate is the next milestone. The project will likely need to ship a 2.x-to-3.x migration utility before adoption picks up, given how many organizations have years of content in the 2.x schema.
