Read the Docs vs Zettlr
A side-by-side editorial comparison of Read the Docs and Zettlr — release velocity, themes, recent moves, and the top alternatives to consider.
Read the Docs vs Zettlr: at a glance
What is Read the Docs?
Read the Docs moves builds to Python 3.14 and Ubuntu 26.04 by default.
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.
What is Zettlr?
Zettlr added admonitions after six years, then spent a release fixing its updater.
Zettlr 4.8.0 brought admonitions, a feature six years in the making, plus translation updates and a fix for a long-standing logic bug in search. 4.9.0 followed in late October to stop a false 'Update failed' error introduced by 4.8, drop macOS 12 and old Ubuntu support, distrust the eMudhra TLS certificates and render reference-style images.

Read the Docs
5.0COLLAB
Read the Docs moves builds to Python 3.14 and Ubuntu 26.04 by default.
◆ Current state
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.
◆ Where it's heading
Two threads run through the releases: a direct upload path for docs built elsewhere, which has had design docs, workflows and onboarding in September and October, and steady hardening of the build platform. Most entries are still lists of merged PRs with dependency bumps.
◆ Prediction
Expect direct upload to move toward general availability and more GitHub App defaults replacing the OAuth app.
Zettlr
2.5COLLAB
Zettlr added admonitions after six years, then spent a release fixing its updater.
◆ Current state
Zettlr 4.8.0 brought admonitions, a feature six years in the making, plus translation updates and a fix for a long-standing logic bug in search. 4.9.0 followed in late October to stop a false 'Update failed' error introduced by 4.8, drop macOS 12 and old Ubuntu support, distrust the eMudhra TLS certificates and render reference-style images.
◆ Where it's heading
Releases arrive roughly monthly and alternate between a headline writing feature and cleanup of the previous one. The app is tracking Electron's platform support, so older operating systems will keep falling away.
◆ Prediction
A small 4.9.x fix release or a feature-led 4.10 in about a month fits the pattern; the entries don't hint at its contents.
