All web browsers, and most other JavaScript environments, have shipped some form of developer console. This standard attempts to finally define the semantics of the console APIs, in an attempt to create convergence.

A list containing some of the observed differences so far in different environments is available in NOTES.md.

We are committed to providing a friendly, safe and welcoming environment for all. Please read and respect the WHATWG Code of Conduct.

This specification is still in its very early stages. It is very much a work in progress.

The Console Standard is written in Bikeshed, with an additional bit of help from emu-algify. The main source is in the file index.bs.

To build the standard locally, you will need a recent version of Node.js. Run npm install in the root directory to set things up. Then you can either use a locally installed copy of Bikeshed by running make or use the HTTP API version by running make remote.

If you want to do a complete "local deploy" including commit and/or branch snapshots, run

./deploy.sh --local

Tests can be found in the console/ directory of web-platform-tests.
