Aleph vs TeamMapper

Both are self-hosted knowledge management tools projects. This page compares how well each one is actually maintained — the part you cannot see from a feature list.

TeamMapper scores 46 against Aleph's 24, putting it clearly ahead on the strength of a higher commit volume and more recent releases. That measures project health, not feature fit — Aleph may still be the right choice if it does what you need.

How to read this

Everything above is measured, not opinion: commit counts and release dates come from the public repositories, and the health score ranks each project against all 1352 projects we track. Read the full method.

What this comparison deliberately does not do is tell you which has the better feature set. Maintenance health tells you which project will still be receiving security fixes in two years. Decide that first, then compare features on the projects that survive the filter.
