LinkedRecords - Graph-based Backend

Developers building collaborative SaaS apps struggle with Firebase/Supabase limitations around authorization and real-time sync. LinkedRecords is an open-source BaaS using graph data models where authorization is built into the data structure itself, not separate rules files.

Graph-based authorization is genuinely having a moment — Authzed (SpiceDB), OpenFGA, and Google Zanzibar have created real developer awareness that relationship-based access control is superior to flat ACL rules, so the underlying thesis is sound. The closest substitutes are Supabase with row-level security plus a separate auth layer, or Fauna DB, which also leans into relational graph semantics but never cracked mainstream adoption. The $2k–10k/mo revenue band is realistic only if this stays in a tight prosumer or small-team SaaS niche, because the open-source route makes monetization structurally hard — Supabase raised $200M+ to give away the free tier and win on hosted cloud, a playbook that's nearly impossible to replicate at indie scale. The single most likely failure mode is the classic open-source BaaS trap: developers star the repo, self-host for free, never convert, and the cloud-hosted version can't differentiate enough on performance or compliance to justify switching costs away from Supabase or Firebase.
