Coder vs Dokku
A side-by-side editorial comparison of Coder and Dokku — release velocity, themes, recent moves, and the top alternatives to consider.
Coder vs Dokku: at a glance
What is Coder?
Coder now patches three release lines at once, and the fixes keep landing on agent access.
Coder's feed shows patch releases on v2.29, v2.34 and v2.36 within three days, which means a v2.35 and a v2.36 mainline shipped that this feed never captured. The late-October fixes are permission work: new API keys stay within the caller's scopes, fetching external agent credentials now requires SSH permission, and read_skill_file reads are confined to the skill directory. Everything else is release-script and DERP client fixes.
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.
Coder vs Dokku: editorial side-by-side
Coder
5.0INFRA · APIS
Coder now patches three release lines at once, and the fixes keep landing on agent access.
◆ Current state
Coder's feed shows patch releases on v2.29, v2.34 and v2.36 within three days, which means a v2.35 and a v2.36 mainline shipped that this feed never captured. The late-October fixes are permission work: new API keys stay within the caller's scopes, fetching external agent credentials now requires SSH permission, and read_skill_file reads are confined to the skill directory. Everything else is release-script and DERP client fixes.
◆ Where it's heading
The security surface is moving to the AI agent features. Two of the three substantive fixes this round concern what an agent can read or which credentials it can obtain, following the June hardening drop on OIDC linking and token theft. The multi-branch backporting continues, so enterprise customers on older lines like 2.29 still get the same permission fixes as the mainline.
◆ Prediction
Expect more permission checks around agent credentials and skills as those features get exercised; the feature releases themselves are not visible in this feed, so their direction is unclear from these entries.
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.
