Private alpha access

Access is limited while the platform is stabilized. Drop your email and we'll send the invite as soon as a slot opens.

By joining, your email and GitHub handle are sent to our email provider (Substack) to manage the waitlist. See our Privacy Policy.

We'll also notify you when Extension.dev reaches general availability. No spam, two emails per quarter at most.
