What is Browser Use?

Browser Use agents can now run on a schedule and work ahead of you, stopping only to get approval

Browser Use is a cloud platform for browser-driving agents, and the August 16 release moves it from on-demand runs to standing automation. V4 agents can be scheduled with pause and resume controls, Automation gets its own entry in Run Settings, and a new Agency skill lets an agent research and prepare work on its own, coming back with follow-ups and asking for approval only before an external action such as sending or publishing. AgentMail is enabled for API runs, agents can configure and disconnect Composio triggers themselves, and bu-2-0-mini-preview joins the model picker while MiniMax M3 leaves it. This lands a week after the X402 release rewrote the free-versus-paid boundary around per-browser-open metering.

What is xfun?

Yihui's utility grab-bag is quietly growing a web server and a headless browser.

xfun is the shared utility layer under knitr, rmarkdown, bookdown and litedown, and its recent releases cluster in three places: the record() function that captures code output for litedown, a local app-serving stack built on R's internal httpd, and a headless-browser toolkit. Version 0.58 replaced direct httpd routing with a proxy and added serve_dir() and random_port(); 0.55 added browser_print() and 0.60 added browser_dom(), which runs JavaScript on a page and returns the rendered DOM.

Browser Use vs xfun: editorial side-by-side

B7.5

Browser Use agents can now run on a schedule and work ahead of you, stopping only to get approval

◆ Current state

Browser Use is a cloud platform for browser-driving agents, and the August 16 release moves it from on-demand runs to standing automation. V4 agents can be scheduled with pause and resume controls, Automation gets its own entry in Run Settings, and a new Agency skill lets an agent research and prepare work on its own, coming back with follow-ups and asking for approval only before an external action such as sending or publishing. AgentMail is enabled for API runs, agents can configure and disconnect Composio triggers themselves, and bu-2-0-mini-preview joins the model picker while MiniMax M3 leaves it. This lands a week after the X402 release rewrote the free-versus-paid boundary around per-browser-open metering.

◆ Where it's heading

Two consecutive releases have built the same thing from opposite ends: pricing that assumes a program is the buyer, and now runtime behaviour that assumes nobody is watching. Scheduling, self-managed Composio triggers, and mail on API runs are the pieces an agent needs to operate between human sessions rather than inside one, and the approval gate on external actions is where the human is being put instead. The model picker is being pruned rather than expanded - one preview model in, one third-party model out - which reads as consolidation onto its own model line.

◆ Prediction

Expect the approval gate to develop into a reviewable queue of pending agent actions, and scheduling to gain finer controls now that V4 agents sit alongside legacy jobs; whether the Agency skill becomes the default agent behaviour rather than an opt-in skill is not visible in these entries.

Yihui's utility grab-bag is quietly growing a web server and a headless browser.

◆ Current state

xfun is the shared utility layer under knitr, rmarkdown, bookdown and litedown, and its recent releases cluster in three places: the record() function that captures code output for litedown, a local app-serving stack built on R's internal httpd, and a headless-browser toolkit. Version 0.58 replaced direct httpd routing with a proxy and added serve_dir() and random_port(); 0.55 added browser_print() and 0.60 added browser_dom(), which runs JavaScript on a page and returns the rendered DOM.

◆ Where it's heading

The package is accreting the infrastructure Yihui's publishing tools need rather than staying a pile of small helpers. Serving directories, allocating ports, proxying the help server, driving a headless browser and printing to PDF are all pieces of one pipeline: render R output to HTML, then get it onto a screen or into a static file without a heavyweight dependency. The rest of the release stream is release-automation tooling for the author's own CRAN workflow and a long tail of parser bug fixes in taml_load().

◆ Prediction

Expect the browser functions to consolidate into a documented interface used directly by litedown, and expect cache_rds() to be fully retired in favour of cache_exec() now that it is no longer recommended.
