Dagger vs Dokku

Dagger vs Dokku: at a glance
What is Dagger?
Dagger now runs the engines for you and reports CI per test, not per job.
Dagger's recent changelog holds two product moves. Cloud Engines, in September, are hosted engines with scale-out, distributed cache and observability, billed only for resources used, with Dagger claiming repeat work costs 5× less. Test-native CI, in October, tracks individual tests, so a failure names the test and only that test is run again. Around them sit cache and plumbing changes, including COPY steps that depend only on the files they copy and SSH-mounted remote filesystems.
What is Dokku?
Dokku's autumn patches swap new features for safer deploys and stricter validation.
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.

◆ Current state
Dagger's recent changelog holds two product moves. Cloud Engines, in September, are hosted engines with scale-out, distributed cache and observability, billed only for resources used, with Dagger claiming repeat work costs 5× less. Test-native CI, in October, tracks individual tests, so a failure names the test and only that test is run again. Around them sit cache and plumbing changes, including COPY steps that depend only on the files they copy and SSH-mounted remote filesystems.
◆ Where it's heading
Both moves rest on the same idea: treat the pipeline as a graph Dagger can see into, then avoid repeating work. A layer cache that survives unrelated file changes, per-test reruns and a distributed cache all reduce what a run must redo. Cloud Engines turn that saving into something sold, the one metered offering in these entries.
◆ Prediction
Expect Test-native CI and Cloud Engines to converge, with per-test reruns offered through hosted engines. That link is inferred from the two launches; the entries neither state it nor give pricing detail.
Dokku
5.0INFRA · APIS
Dokku's autumn patches swap new features for safer deploys and stricter validation.
◆ Current state
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.
◆ Where it's heading
The August k3s parity push has given way to a hardening pass through commands that used to fail quietly. A second thread makes configuration declarative: storage mounts, scheduler-k3s metadata and chart overrides each gained a whole-set form, which suits automation tools more than people at a terminal. Machine use of the CLI remains the through-line.
◆ Prediction
Expect the whole-set form to reach more properties, since three subsystems have now gained it. Patch releases should stay frequent, and the notes give no sign of a move past the 0.38 line.
