Most collaboration SDKs are hosted SaaS: your users' comments live on someone else's servers. Pulse is self-hosted: one tag adds comments pinned to pixels, live cursors, presence, reactions, and voice/video notes to any website, backed by your own Postgres. The hard part is pins that don't drift: Pulse anchors each one to three DOM landmarks with barycentric coordinates and degrades through four fallback tiers, so pins survive reflows and redesigns. Multi-tenant, themeable, REST API.
