One script tag
A dependency-free widget in a shadow root. It doesn’t inherit your CSS and your page doesn’t inherit its bugs.
Gutternote
Comment on any Vercel preview. Decide for yourself where those comments live.
No seat required
Designers, PMs and clients comment without a GitHub account — the people who leave most preview feedback in the first place.
Pluggable storage
Keep comment bodies in Gutternote, in your own GitHub repo, or on an endpoint you run. Pin positions always stay with us so pins render instantly.
Self-hostable
One Go binary and a Postgres URL. Run the whole thing in your own VPC.
