Zenler vs Chamilo
A side-by-side editorial comparison of Zenler and Chamilo — release velocity, themes, recent moves, and the top alternatives to consider.
Zenler vs Chamilo: at a glance
What is Zenler?
Zenler publishes version-numbered fix lists with the occasional real feature buried at the bottom.
Every entry is a build stamp wrapping a long list of bug fixes, and the actual releases sit at the end of those lists. Reading past the fixes: the Community gained member search, username-scoped post search, language support, and a rule requiring a profile picture and bio before entry; billing gained self-serve plan changes and cancellation, invoice downloads for admins, retained access through the paid period, and instant refunds inside 30 days; reporting gained a student-wise quiz detail report with export. Gamification appears as a single line with no description. The feed stops at April 2026.
What is Chamilo?
Chamilo's 3.0 beta quietly turns the LMS into an MCP server agents can author courses through.
Chamilo runs three lines at once. The legacy 1.11 branch takes security and bugfix releases roughly quarterly, 2.0 reached GA in April and has drawn three patch releases since, and a 3.0 line opened on 13 August. The 3.0 beta is where the direction sits: 456 changes spanning 88 plugin fixes, a 44-item security sweep, and a new MCP server with OAuth 2.1 that exposes course authoring and review to outside clients. The feed's own bodies are unreliable here - both 3.0 tags arrived carrying a single line of text, and the 2.0 GA release reached it only as scraped page fragments.

Zenler
0.0EDTECH
Zenler publishes version-numbered fix lists with the occasional real feature buried at the bottom.
◆ Current state
Every entry is a build stamp wrapping a long list of bug fixes, and the actual releases sit at the end of those lists. Reading past the fixes: the Community gained member search, username-scoped post search, language support, and a rule requiring a profile picture and bio before entry; billing gained self-serve plan changes and cancellation, invoice downloads for admins, retained access through the paid period, and instant refunds inside 30 days; reporting gained a student-wise quiz detail report with export. Gamification appears as a single line with no description. The feed stops at April 2026.
◆ Where it's heading
The ratio tells the story — the bulk of each release is repair on funnels, emails, reports, cloning, and checkout, which is what a broad course-and-marketing platform costs to keep running. Where new work does land it clusters in two places: the Community, which is being built into a real social surface rather than a comment thread, and self-serve billing, which removes support from the cancel-and-refund path. The double opt-in rework touches both by making enrollment wait for verified email.
◆ Prediction
Expect Community to keep accumulating the moderation and discovery features that make it usable at size, since search and mandatory profiles are the first two. The unexplained gamification line is the one thing the entries cannot support a read on.
Chamilo
6.3EDTECH
Chamilo's 3.0 beta quietly turns the LMS into an MCP server agents can author courses through.
◆ Current state
Chamilo runs three lines at once. The legacy 1.11 branch takes security and bugfix releases roughly quarterly, 2.0 reached GA in April and has drawn three patch releases since, and a 3.0 line opened on 13 August. The 3.0 beta is where the direction sits: 456 changes spanning 88 plugin fixes, a 44-item security sweep, and a new MCP server with OAuth 2.1 that exposes course authoring and review to outside clients. The feed's own bodies are unreliable here - both 3.0 tags arrived carrying a single line of text, and the 2.0 GA release reached it only as scraped page fragments.
◆ Where it's heading
The rewrite has stopped being the story and the agent surface has started. 2.0 spent its cycle absorbing the legacy feature set - LTI, ONLYOFFICE, the plugin catalogue - and reached GA; 3.0's first beta spends most of its weight on that same restoration work but adds something no 2.0 release contains, an MCP server with OAuth 2.1 auto-connect and tools that write rather than only read. Model providers are being wired directly into the AI helper alongside it. Security remains constant across all three branches, with 44 security items in the 3.0 beta alone.
◆ Prediction
Expect the MCP tool surface to widen in the next 3.0 beta, since the first pass already moved past read-only lookups into course authoring and review. Whether 3.0 becomes the supported line or 2.0 keeps taking patches is the question the tags themselves do not answer.
