About Nimbus
FuseBase pivots from client portals toward AI app-building with a structured 'Flow' process.
FuseBase (formerly Nimbus) is repositioning from a client-portal and collaboration tool into an AI app-development platform. Recent product entries — FuseBase Flow, 'Everything New in FuseBase AI Apps,' and monthly AI-coding updates — show real investment in agentic, phase-gated app building. Interleaved are SEO listicles (Clinked, Moxo, Replit, Lovable alternatives) that still sell the portal heritage.
