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 Gitness?

Harness Open Source last shipped in August 2025, on this feed at least

The feed holds two releases of Harness Open Source, tracked here as Gitness. v3.2.0 in May 2025 added Git LFS, default reviewers through branch rules and a Revert PR option; v3.3.0 that August added tag rules, a PR dashboard upgrade with favourite repositories, and a fix for a Git LFS upload path flaw. Nothing newer appears here.

Dagger now runs the engines for you and reports CI per test, not per job.

◆ 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.

Harness Open Source last shipped in August 2025, on this feed at least

◆ Current state

The feed holds two releases of Harness Open Source, tracked here as Gitness. v3.2.0 in May 2025 added Git LFS, default reviewers through branch rules and a Revert PR option; v3.3.0 that August added tag rules, a PR dashboard upgrade with favourite repositories, and a fix for a Git LFS upload path flaw. Nothing newer appears here.

◆ Where it's heading

Both releases deepen code-hosting governance: branch rules, then tag rules, plus review routing through Code Owners. That is parity work against established Git hosts rather than a new direction. With entries more than a year old, the feed shows where the project was heading in 2025, not where it is now.

◆ Prediction

The entries do not support a confident call: there is no release in this feed after v3.3.0, so it is unclear whether the project slowed or the feed stopped tracking it.
