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 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.

Coder vs Dagger: editorial side-by-side

C
Coder
INFRA · APIS
5.0

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.

D
Dagger
INFRA · APIS
2.5

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.
