Pebble OS is getting what founder Eric Migicovsky calls one of its most significant updates: support for plugins. Plugins are small programs with no screen of their own that provide data or perform actions for any app or watch face on a Pebble.
A plugin is written in JavaScript and runs in the background in the Pebble app on the phone, not on the smartwatch. This has two practical effects: the code does not drain the watch battery, and the data stays on the user's device. Migicovsky cites weather, finance and traffic as data examples, and home control, music and webhooks as actions. A phone plugin can also read calendar entries and reminders or control smart devices.

For developers the benefit is saved time: instead of coding each feature from scratch, they use a ready-made plugin. A watch face that shows the weather no longer needs its own weather service and API key, since one source can feed any face built to use it. Migicovsky compares plugins to Apple Watch complications, but says they are far more flexible, with greater freedom in how a face looks and displays data.
On security, each app and watch face must get separate permission to access GPS location, specific internet URLs and other sensitive data, so users decide case by case.
For now the feature is a developer preview available only in the SDK, with no date yet for a full rollout. Users will see the change later, once plugins start appearing in third-party apps and watch faces.
