Dokku vs Fail2Ban: at a glance
What is Dokku?
Dokku ships patches weekly, and quietly grows a Kubernetes backend under its single-host roots.
Dokku releases on a near-weekly patch cadence, and most entries are dominated by Dependabot bumps to test fixtures. The real content is thin but consistent: a command injection fix in docker options evaluation, per-app Let's Encrypt emails on k3s, atomic buildpack list replacement, custom chown values, and JSON output added to apps:list, ps:scale and docker-options reports. Several tags in early July were published within minutes of each other and out of version order.
What is Fail2Ban?
Fail2Ban's last release was an interim beta 14 months ago; the feed spans eight years in six entries.
Fail2Ban has published one release since April 2024, and it was explicitly labelled an interim beta. The six most recent entries cover eight calendar years — 1.1.1.beta0 in June 2025, 1.1.0 in April 2024, then two 1.0.x releases from late 2022 and a pair of 0.10/0.11 releases from 2020. Every entry defers its substance to a linked ChangeLog, so the feed itself carries version numbers, joke release names and little else.

Dokku
5.0INFRA · APIS
Dokku ships patches weekly, and quietly grows a Kubernetes backend under its single-host roots.
◆ Current state
Dokku releases on a near-weekly patch cadence, and most entries are dominated by Dependabot bumps to test fixtures. The real content is thin but consistent: a command injection fix in docker options evaluation, per-app Let's Encrypt emails on k3s, atomic buildpack list replacement, custom chown values, and JSON output added to apps:list, ps:scale and docker-options reports. Several tags in early July were published within minutes of each other and out of version order.
◆ Where it's heading
Two threads carry through. The scheduler-k3s plugin keeps accumulating what a real platform needs — helm chart previews, autoscaling auth state, control-plane node matching, per-app certificate configuration — which pushes Dokku beyond the single-host Docker tool it started as. The second is machine readability: command after command gains --format json, turning the CLI into something automation can consume rather than parse.
◆ Prediction
Expect JSON output to keep spreading command by command until it is the norm rather than a flag, and expect the k3s scheduler to stay the destination for new capability while the Docker scheduler receives fixes. The patch train shows no sign of consolidating into a minor release.
Fail2Ban
0.0INFRA · APIS
Fail2Ban's last release was an interim beta 14 months ago; the feed spans eight years in six entries.
◆ Current state
Fail2Ban has published one release since April 2024, and it was explicitly labelled an interim beta. The six most recent entries cover eight calendar years — 1.1.1.beta0 in June 2025, 1.1.0 in April 2024, then two 1.0.x releases from late 2022 and a pair of 0.10/0.11 releases from 2020. Every entry defers its substance to a linked ChangeLog, so the feed itself carries version numbers, joke release names and little else.
◆ Where it's heading
The stated purpose of the last substantive release was Python 3.12 and 3.13 compatibility, which is maintenance to stay installable rather than development. Release intervals have widened from months to years, and the most recent tag is a beta that has not been followed by a final. On the evidence here, the project is in preservation mode.
◆ Prediction
The most likely next event is another compatibility release triggered by a Python version that breaks the current code, not a feature release. Whether 1.1.1 ever leaves beta is not something these entries indicate — no further tag has followed it in over a year.
