What is chromote?

chromote turned the browser itself into a pinned, downloadable dependency.

chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.

What is Knock?

Knock is pulling every customer-data source into notifications, then putting an agent on top.

Knock is a notification infrastructure layer, and the last two months have gone into two things: widening what can trigger a workflow, and making the resulting data legible. Amplitude and Clay both landed as first-class data sources, so product events, cohort changes and enriched CRM rows now drive messaging directly rather than through customer-written glue. The workflow engine gained a wait-for-event primitive, and the template editor was rebuilt around block editing.

chromote turned the browser itself into a pinned, downloadable dependency.

◆ Current state

chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.

◆ Where it's heading

The package has moved from reacting to Chrome upgrades to controlling them. The 0.3.0 and 0.4.0 pair tracked the headless-mode transition by first adding an option and then flipping the default; 0.5.0 removed the need to track it at all by managing versioned binaries through Chrome for Testing. Alongside that, the session API keeps accumulating helpers that collapse multi-step DevTools call sequences, such as $go_to() and $set_viewport_size().

◆ Prediction

The version-management features shipped marked experimental, so the likely next step is stabilizing that API and extending the session helpers that wrap common DevTools sequences.

Knock is pulling every customer-data source into notifications, then putting an agent on top.

◆ Current state

Knock is a notification infrastructure layer, and the last two months have gone into two things: widening what can trigger a workflow, and making the resulting data legible. Amplitude and Clay both landed as first-class data sources, so product events, cohort changes and enriched CRM rows now drive messaging directly rather than through customer-written glue. The workflow engine gained a wait-for-event primitive, and the template editor was rebuilt around block editing.

◆ Where it's heading

The shape is a product moving up from delivery mechanics toward the surrounding workflow. Sources reduce the integration code a customer writes before Knock is useful; the agent layer reduces the reporting work after. Category and tag management being pulled into dedicated dashboard pages is the housekeeping that follows: the primitives got numerous enough to need their own administration surface.

◆ Prediction

Expect the data-source list to keep growing along the same lines — warehouse and product-analytics tools that already hold the user state Knock needs — and for the agent to be given more of the dashboard's read surface.
