Both are Postgres-adjacent* backends that spare you from building auth, storage, and real-time from scratch — but they sit at very different points on the operational-overhead scale. Supabase is a full managed platform; PocketBase is a single self-hosted binary built for small, fast-moving projects. *PocketBase actually runs on SQLite, not Postgres — that's part of what keeps it light.
For a scrappy MVP that needs to ship in weeks and might get killed or pivoted, PocketBase's near-zero operational overhead is hard to beat — a few dollars of VPS hosting and you're live. Once a product has real traction and you're planning for scale, complex queries, or a larger team, Supabase's managed infrastructure and fuller Postgres feature set earn their extra overhead.
PocketBase can run production apps with moderate traffic — it's used beyond prototyping. The practical ceiling is lower than a managed platform because you're responsible for backups, scaling, and uptime yourself, so it fits best when the operational simplicity is worth that tradeoff.
Not necessarily, but it is more infrastructure than a small MVP strictly needs. If you're validating an idea with a handful of users, PocketBase's single-binary simplicity gets you to launch faster with less to manage. Supabase pays off once you expect growth or need Postgres-specific features from day one.
Both use relational-style data (SQLite for PocketBase, Postgres for Supabase), which makes migration more straightforward than moving between very different data models. You'll still need to adapt schema, auth, and API calls, so budget real engineering time rather than expecting an automatic switch.
Yes, both offer real-time subscriptions out of the box. PocketBase's implementation is simpler and tied to its single-server model, while Supabase's real-time layer is built to work across a distributed, managed infrastructure — worth checking if you have specific real-time scaling needs.
