Skipper vs TestingBot: at a glance
What is Skipper?
Skipper adds raw-path routing predicates after a week of security and maintenance tags.
Skipper tags a release for nearly every merge. v0.28.39 adds four path predicates, prefix and regexp matching on either the normalized or raw request path, so routes can tell an encoded %2f from a slash, with benchmarks showing zero allocations. Just before it, v0.28.37 fixed security advisory GHSA-9hwf-c47m-j4pg in the cache() filter and v0.28.38 removed a direct syscall dependency. The rest of the week was test-certificate consolidation and dependency builds.
What is TestingBot?
A browser grid that spent the summer becoming a team product, and is now opening itself to agents.
TestingBot runs a cross-browser and real-device cloud, and the last three months have gone almost entirely into what surrounds a test run rather than the run itself: custom roles enforced identically in dashboard and API, service accounts so pipelines stop borrowing a person's credentials, enforced two-factor authentication, comments with @mentions on failed runs, one-click filing into GitHub, Jira, Trello, Asana or Azure DevOps, and a notification inbox tying it together. The grid work continues underneath — WebRTC streaming for iOS simulators, a rebuilt web inspector, new devices and browser versions on the usual cadence.

Skipper adds raw-path routing predicates after a week of security and maintenance tags.
◆ Current state
Skipper tags a release for nearly every merge. v0.28.39 adds four path predicates, prefix and regexp matching on either the normalized or raw request path, so routes can tell an encoded %2f from a slash, with benchmarks showing zero allocations. Just before it, v0.28.37 fixed security advisory GHSA-9hwf-c47m-j4pg in the cache() filter and v0.28.38 removed a direct syscall dependency. The rest of the week was test-certificate consolidation and dependency builds.
◆ Where it's heading
Skipper keeps taking on edge responsibilities, from caching to identity, while tightening its hot path. Raw-path matching gives operators finer routing control over encoded URLs, a frequent source of proxy bypass bugs, and fits the recent security focus. The certificate refactor still points to TLS work ahead.
◆ Prediction
Expect a TLS-related feature built on the unified certificate setup, plus further cache-filter fixes. Otherwise more Dependabot tags.
TestingBot
5.0INFRA · APIS
A browser grid that spent the summer becoming a team product, and is now opening itself to agents.
◆ Current state
TestingBot runs a cross-browser and real-device cloud, and the last three months have gone almost entirely into what surrounds a test run rather than the run itself: custom roles enforced identically in dashboard and API, service accounts so pipelines stop borrowing a person's credentials, enforced two-factor authentication, comments with @mentions on failed runs, one-click filing into GitHub, Jira, Trello, Asana or Azure DevOps, and a notification inbox tying it together. The grid work continues underneath — WebRTC streaming for iOS simulators, a rebuilt web inspector, new devices and browser versions on the usual cadence.
◆ Where it's heading
Two directions are visible. The platform is being made safe for organisations rather than individuals, which is what roles, service accounts, 2FA and audit-friendly reporting add up to. Alongside it, the grid is being made reachable by software instead of people: an Insights API exposing pass rates and flakiness, embeddable build reports for CI dashboards, GitHub checks on every pull request, and now Vibium's CLI and MCP server pointed straight at the grid over WebDriver BiDi. The AI work so far reads results — failure analysis, documentation questions — while Vibium is the first path where something other than a human-written script drives the browser.
◆ Prediction
Expect the agent-facing path to be developed further, since supporting Vibium's MCP server without extra configuration is a small step from offering a first-party one, and expect the device and browser catalogue to keep rotating on its established cadence.
