Integration Not Database Creates Lock-in
Diving deeper into
Founding engineer at healthtech startup on Supabase's ready-at-scale credibility gap
most vendors do offer a way out because they want to address that lock-in concern. Even so, getting off still sucks regardless.

Reviewing context
The real lock in is not the database file, it is the operating system a team builds around the vendor. Once auth, storage, backups, local dev, row level security, and internal workflows are wired into one managed stack, the exit path becomes a cross functional rebuild project, not a clean data export. That is why open source foundations help at the margin, but still do not remove the pain of switching.
-
In the healthtech case, the feared pain was not losing Postgres compatibility. It was coordinating multiple databases and replicas, preserving uptime, and avoiding a long detour where engineers stop shipping product to replatform core data infrastructure.
-
The managed stack can also deepen lock in through convenience. One public sector startup uses Supabase for database, auth, and storage, edits production data in the browser, relies on automatic backups and local instances, and expects a full migration to take months.
-
Comparable platforms show the same pattern in different forms. A CTO pushing teams from Supabase to Firebase said the hard part is untangling security rules, auth, and infrastructure conventions from the app code, even when the underlying move can be done in about a week for smaller apps.
This points to a market split. All in one backends will keep winning early projects because they collapse setup into a few clicks, but as systems become more regulated, multi product, or operationally critical, buyers will favor tools whose escape path is proven in practice, not just promised in architecture.
