As answered by people managing CodePen and ShipRelay.io.
ShipRelay.io's answer:
Most changelog tools handle either generation or delivery, but not both. ShipRelay auto-generates changelogs from GitHub commits and delivers them via email digest, in-app widget, and hosted page — with engagement analytics to track who's actually reading updates.
ShipRelay.io's answer:
Generation-only tools like git-cliff and semantic-release create changelogs but don't deliver them to users. Delivery tools like Beamer and LaunchNotes require manual writing and start at $99-249/mo. ShipRelay does both — auto-generates and delivers — starting at $19/mo with a free tier.
ShipRelay.io's answer:
Developers and small SaaS teams who ship frequently but don't have time to manually write and distribute release notes. Especially solo devs and indie makers who want their users to know what's shipping without adding another task to every release.
ShipRelay.io's answer:
We noticed that generating changelogs is basically solved — AI and open-source tools handle that well. But most changelogs still end up buried in GitHub releases where users never see them. The real gap is distribution: getting updates in front of users consistently without manual effort. ShipRelay was built to close that gap.
ShipRelay.io's answer:
Next.js, Supabase, Stripe, Vercel, Resend, and Claude Haiku for AI-powered changelog generation.
