In their own words
Supabase
Supabase is a backend platform built around a Postgres database, with services for authentication, storage, realtime data, and server-side functions. Every project includes a Postgres database, and paid plans add database branching and backups. Supabase Auth supports email and password, passwordless, OAuth, and mobile logins through identity providers and APIs. Realtime can listen for database changes, sync user states, and broadcast data to subscribed clients; Edge Functions run server-side code close to users. Official client libraries are available for JavaScript/TypeScript, Dart/Flutter, Swift, and Python, and documentation covers self-hosting. Supabase says data is encrypted at rest with AES-256 and in transit via TLS, and that it is SOC 2 Type 2 compliant and ISO 27001 certified. EU-hosted projects keep primary database data in-region; hosted HIPAA use requires a Business Associate Agreement. The free plan includes two active projects, paused after one week of inactivity. Pro starts at $25 /mo and includes email support; Team starts at $599 / month, while Enterprise pricing is custom.
