Introduction

Pepper is an interface that web browsers (specifically, Chromium) provide for implementing browser plugins. Pepper started out as an extension to Mozilla's widely-used NPAPI interface, but Pepper v2 provides a new API that is not an extension to NPAPI.

NaCl's integration with Chromium is implemented using Pepper. However, NaCl also makes a Pepper-based interface available to web apps over IPC.
