BareProxy Maintenance and Failover Pages Plugin: A Static Page When the Backend Is Down

Thu, 08 Oct 2026 00:00:00 +0000

Status: built, number 1 of 21 in BareProxy’s build order, and out in BareProxy 0.4.0 as maintenance.wasm on the releases page. The plugins are built easiest first, and this one was the quickest: one callback on the way in, one on the way out. Its manual is the README in the code repository.

When an app goes down, visitors get whatever the proxy says by default: a bare “502 Bad Gateway” or “503 Service Unavailable”. That reads like the site is broken, because it is. A page that says “we’re doing maintenance, back at 14:00” with the site’s own look reads like a site that’s being looked after.
