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 TestingBot?

TestingBot's autumn work is plumbing: a rebuilt tunnel and another bug-tracker link.

TestingBot runs a cross-browser and real-device cloud. October brought Tunnel v5, a rewrite of its local-testing tunnel with host allowlists, SSH host key checks, SOCKS5, Kerberos and PAC proxy support, self-contained builds without Java, and health endpoints with JSON logs. A Linear integration files bugs from manual sessions, and an iPhone Duo simulator lets teams test a foldable iPhone before Apple ships it. Vibium's agent-driven automation joined the grid in August and Mobilewright tests in October.

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.

TestingBot's autumn work is plumbing: a rebuilt tunnel and another bug-tracker link.

◆ Current state

TestingBot runs a cross-browser and real-device cloud. October brought Tunnel v5, a rewrite of its local-testing tunnel with host allowlists, SSH host key checks, SOCKS5, Kerberos and PAC proxy support, self-contained builds without Java, and health endpoints with JSON logs. A Linear integration files bugs from manual sessions, and an iPhone Duo simulator lets teams test a foldable iPhone before Apple ships it. Vibium's agent-driven automation joined the grid in August and Mobilewright tests in October.

◆ Where it's heading

The summer made the platform fit for teams; the autumn makes it fit for corporate networks and CI. Tunnel v5 targets the place enterprise trials usually stall, behind proxies and security reviews, and its config-file and environment-variable setup suits pipelines and Docker. The integration list keeps growing one tracker at a time, while the device catalogue continues its usual rotation.

◆ Prediction

Expect further CI-oriented tunnel and reporting work, and more automation frameworks on the grid alongside Mobilewright and Vibium. The Vibium MCP path has had no follow-up in these entries.
