A side-by-side editorial comparison of Drone and Harbor — release velocity, themes, recent moves, and the top alternatives to consider.
Drone vs Harbor: at a glance
What is Drone?
Drone's source now ships as Harness Open Source, and it last released in August 2025.
Both tracked releases are tagged Harness Open Source from the harness/harness repo, which is where Drone's code now lives. v3.2.0 added Git LFS, PR revert, retargeting and Code Owner auto-assignment; v3.3.0 added favorite repos, tag protection rules and a fix for a Git LFS path-traversal issue. Nothing has shipped since August 2025.
What is Harbor?
Harbor's patch train is now mostly about undoing regressions from its own security hardening.
Harbor is shipping patch candidates on both the 2.14 and 2.15 lines. The 2.15.3 batch tightened security with manifest upload size limits, registry ping URL constraints, a fix for robot-name proxy-cache poisoning, and CSV formula neutralization. The 2.15.4 and 2.14.6 candidates then roll back defaults that broke existing setups, re-allowing webhooks to private networks and legacy signer pulls.

Drone

Drone's source now ships as Harness Open Source, and it last released in August 2025.
◆ Current state
Both tracked releases are tagged Harness Open Source from the harness/harness repo, which is where Drone's code now lives. v3.2.0 added Git LFS, PR revert, retargeting and Code Owner auto-assignment; v3.3.0 added favorite repos, tag protection rules and a fix for a Git LFS path-traversal issue. Nothing has shipped since August 2025.
◆ Where it's heading
The product has moved from a CI engine toward a full code-hosting platform with PR workflows and branch/tag governance. The 14-month gap since v3.3.0 points to slow or paused open-source releases.
◆ Prediction
The entries give no sign of a next release; another quiet period is the base case.
Harbor
5.0INFRA · APIS
Harbor's patch train is now mostly about undoing regressions from its own security hardening.
◆ Current state
Harbor is shipping patch candidates on both the 2.14 and 2.15 lines. The 2.15.3 batch tightened security with manifest upload size limits, registry ping URL constraints, a fix for robot-name proxy-cache poisoning, and CSV formula neutralization. The 2.15.4 and 2.14.6 candidates then roll back defaults that broke existing setups, re-allowing webhooks to private networks and legacy signer pulls.
◆ Where it's heading
The registry is hardening its attack surface and paying for it in compatibility: stricter defaults landed, users hit regressions, and maintainers are now exposing switches in harbor.yml and restoring the permissive behavior. Earlier in the cycle, 2.15.2 swapped Redis for Valkey as the cache backend, a quiet infrastructure decision that now applies to every new install.
◆ Prediction
Expect 2.15.4 and 2.14.6 to reach GA with these regression fixes, and future security changes to ship as opt-in configuration switches before they become defaults.
