SvellBell's answer
It’s ultra-lightweight: Only 0.3kb in size. Competitors are often bloated (500kb+) and hurt your site’s speed.
It’s free: There is a generous Free Tier for solo devs. Competitors often start at $49/mo.
It’s simple: No complex enterprise features (SSO, tracking). Just a clean widget that works in 2 minutes.
Zero Bloat: It respects your users' privacy and load time.
SvellBell's answer
Zero dependencies, fast performance, easy drop-in script integration, privacy-friendly EU hosting, and a generous free tier compared to heavier, more expensive changelog SaaS tools.
SvellBell's answer
I built SvellBell because I was tired of bloated changelog scripts slowing down my apps. Existing tools felt like overkill for solo devs, so I created a 0.3kb, dependency-free alternative that focuses purely on speed and simplicity.
