felixrieseberg/lets-encrypt-preview
stale
significant_divergence
Selected Choose this fork only if your goal is to mine an early IIS/Windows porting effort. For active certificate automation, upstream Certbot is the clearly safer and more complete base.
pde/letsencrypt
stale
significant_divergence
Prefer this fork only if you specifically need its legacy Apache/Debian automation or want an old Certbot-era codebase. For new deployments, upstream Certbot is the safer choice because this fork is stale, substantially divergent, and behind on maintenance.
kuba/letsencrypt
stale
significant_divergence
Choose this fork only if you need the old legacy Lets Encrypt client shape. For anyone wanting an actively maintained ACME client, the upstream Certbot project is the safer default.
Choose this fork only if you want a near-zero-modification copy of Certbot; otherwise upstream is likely the better default because it is current and this fork adds no visible capabilities.
trkhanh/certbot
stale
significant_divergence
Prefer upstream unless you specifically need this 2020-era fork’s packaging and installer changes. For production ACME use, the fork is too stale and too far behind to be a good default choice.
robstradling/certbot
stale
significant_divergence
Choose upstream unless you specifically need the legacy auto-installer or old packaging behavior. This fork looks like a frozen, highly customized 2019 snapshot rather than a safe substitute for active Certbot maintenance.
li-xunhuan/certbot
stale
significant_divergence
Prefer upstream unless you specifically need legacy Certbot internals or old installer behavior. For new adopters, this fork looks too stale and too far behind to be a practical base.
neufeldtech/certbot-bigip
stale
significant_divergence
Choose this fork only if BIG-IP support is the main requirement. For general Certbot use, upstream is the better choice because this fork is old, highly divergent, and inactive.
kristopolous/tollbot
active
significant_divergence
Choose this fork if your goal is to monetize or control AI scraping at the HTTP edge. Do not choose it if you need a maintained ACME certificate client; this fork is a substantial product rewrite with different operational goals.
baby636/certbot
slowing
significant_divergence
Choose this fork only if you need its legacy installer and workflow changes. If you want current Certbot behavior, active upstream maintenance, and the latest plugin/integration changes, upstream is the safer default.
