Astro Build Info Plugin FAQs
Clear answers explaining what Astro Build Info records — and what it intentionally avoids.
Last Updated: 01 April 2026
Does Astro Build Info run at runtime?
No. It runs only during astro build and produces static output.
What metadata is included?
Framework name, Astro output mode, configured site URL, and build timestamp.
Does Astro Build Info expose environment or CI details?
No. Environment variables, machine data, and CI metadata are deliberately excluded.
Is the output compatible with CDNs?
Yes. The static file can be cached indefinitely behind any CDN.
What happens if the file cannot be written?
A warning is logged and the build continues safely.
Will runtime metadata be supported?
Possibly in v2 for hybrid or server output. v1 intentionally avoids this.
Is Astro Build Info open source?
Yes. Astro Build Info is released under the MIT license.
