Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

First-install notes

  • Edit plugin.config to load plugins In plugin.config, add one line per plugin with the plugin file name and any arguments, for example my-plugin.so plus options. If the line or path is wrong, that plugin will not load. source
  • ModSecurity Lua plugin needs paths If you use the example ModSecurity Lua plugin, point the plugin line at the Lua script and ModSecurity config file. Wrong paths mean the plugin will not start working. source

Common questions

How do I load a plugin in Apache Traffic Server?

Add one line per plugin in plugin.config with the plugin file name and any arguments. If the line or path is wrong, that plugin will not load.

How do I point a CMake build at OpenSSL or another dependency?

Set a variable named for the dependency with ROOT, except OpenSSL uses OPENSSL_ROOT_DIR. For example, pass -Djemalloc_ROOT and -DOPENSSL_ROOT_DIR to cmake with the dependency paths.

Which versions were updated in the July 2026 security release?

Apache Traffic Server 9.2.14 and 10.1.3 fixed 34 vulnerabilities. Upgrading is strongly recommended.
