backend options for a solo product that needs real auth

ranked by how much backend you want to own. includes visual, managed, and self-hosted paths; the notes call out where 'no-code' quietly ends

01
Xano
most visual option here for APIs, data, auth, and business logic
02
Supabase
Postgres underneath; learn row-level security before inviting users
03
Firebase
strong mobile path, but model query patterns before choosing Firestore
04
Appwrite
05
Backendless
visual workflows go far; test the escape hatch for custom server logic
06
Bubble backend workflows
07
Directus
excellent when the database also needs a usable admin and content layer
08
Hasura
09
PocketBase
tiny single-binary setup; confirm its pre-1.0 tradeoffs fit the risk
10
Convex
11
NocoDB
better as a collaborative data interface than a full Firebase replacement
12
Baserow
13
Airtable
fine for validation and ops; rate limits and data shape become the ceiling
