What is Rootly?
Rootly keeps widening what its AI observes — now the incident call itself, in any language.
The AI work runs along two lines: evidence gathering across the observability stack, and the incident call itself. Meeting Scribe now detects the language spoken on a call and transcribes it with no configuration, removing the setup step that made the feature single-language in practice. Around it sits the routine platform work — catalog sync, alert-storm muting, on-call widgets, retrospective templates.
What is watcher?
watcher is a thin filesystem-events binding whose releases are mostly build work.
The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.

Rootly
6.3INFRA · APIS
Rootly keeps widening what its AI observes — now the incident call itself, in any language.
◆ Current state
The AI work runs along two lines: evidence gathering across the observability stack, and the incident call itself. Meeting Scribe now detects the language spoken on a call and transcribes it with no configuration, removing the setup step that made the feature single-language in practice. Around it sits the routine platform work — catalog sync, alert-storm muting, on-call widgets, retrospective templates.
◆ Where it's heading
The pattern is consistent: every artifact an incident produces — telemetry, chat, the call — becomes something Rootly's AI reads and turns into retrospective material. Language detection is a small change with a specific consequence: distributed teams whose incident calls are not held in English now get the same automated record as everyone else. The catalog and alerting work underneath keeps making that record attributable to a service and an owner.
◆ Prediction
Expect Scribe output to feed the retrospective AI-blocks directly, closing the loop from call to written retrospective without a manual step.
watcher
0.0INFRA · APIS
watcher is a thin filesystem-events binding whose releases are mostly build work.
◆ Current state
The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.
◆ Where it's heading
The API is deliberately small and appears finished; the work that remains is making the C dependency install cleanly everywhere. Dropping cmake follows the same move nanonext made, which is not a coincidence — both come from the same author and both are aiming at environments where installing a build system is not an option.
◆ Prediction
With cmake gone and the bundled library current, further releases are most likely to track libfswatch upstream rather than extend the R interface.
