Push the latest changes to Github and automatically make beta versions available to your test users.
Keep source code safely behind private repos and make the builds available to your test users publicly on the platform.
Invite cohorts of users to beta test your extensions, collect feedback and iterate before going live to the webstores.
Reduce the friction. Give your test users easy, self-serve access to the builds for different browsers.
I don't need to get any faster in BED. Maybe safer. I have real users™ now and I have to start being more serious in BED! I'm talking unit testing, git hooks, commit linting... stuff like that.
If you are a developer, visit the developers page to learn about the benefits of following the Bedframe approach to BED or get started with the documentation.
