Supabase

Supabase is a backend platform built around a Postgres database, with services for authentication, storage, realtime data and server-side functions. Each project includes a Postgres database; paid plans add database branching and backups. Supabase Auth supports email and password, passwordless access, OAuth and mobile logins through identity providers and APIs. Realtime can listen for database changes, sync user states and broadcast data to subscribed clients, while Edge Functions run server-side code close to users. Official client libraries are available for JavaScript/TypeScript, Dart/Flutter, Swift and Python, and Supabase provides documentation for self-hosting. Supabase says customer 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, which pause after one week of inactivity. Pro starts at $25/mo and includes email support; Team and Enterprise add higher support options and other plan features.

Supabase combines Postgres with several application backend services and offers both hosted plans and self-hosting documentation. Review free-tier project limits and plan-specific support before choosing a deployment.

Supabase may suit developers building applications that need a Postgres backend with authentication, storage, realtime features or server-side functions. Its self-hosting documentation may also be relevant to teams seeking that deployment option.

Supabase is a backend platform built around Postgres, with authentication, file storage, realtime updates, and server-side functions. It best suits developers building apps that need a relational database and several backend services together. Its free tier is a useful starting point, while production teams should weigh its quotas, inactivity pauses, and manual scaling against their needs.

Overview

Each Supabase project comes with a Postgres database, including support for extensions. That makes it a sensible choice for applications whose data fits a relational model and for teams that want Postgres at the center of their backend. Paid plans add database branching, and the platform supports backups, point-in-time recovery, and read replicas. Scaling is manual, however, so teams must account for operating growth themselves.

Supabase brings Auth, Storage, Realtime, and Edge Functions alongside the database. This breadth can keep core backend components in one platform; a project needing only authentication may find the larger package unnecessary.

Key features

Database and application services

Supabase Auth covers 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 through a globally distributed network. Together, these capabilities address several common application-backend needs around a Postgres database.

Libraries, integrations, and security

Official client libraries are available for JavaScript and TypeScript, Dart and Flutter, Swift, and Python. Supabase documents Vercel Marketplace project management and project provisioning through Stripe CLI. It also provides instructions for self-hosting, giving teams a route to run the platform themselves.

Supabase says data is encrypted at rest with AES-256 and in transit using TLS, and that it is SOC 2 Type 2 compliant and ISO 27001 certified. HIPAA use of the hosted platform requires a Business Associate Agreement; EU-hosted projects keep primary database data in-region, and a GDPR Data Processing Agreement is available. Teams with regulatory requirements should match these terms to their deployment and obligations.

Pricing

The freemium plan structure ranges from a capped no-cost option to custom-priced enterprise service. The listed paid starting prices are $25 / month for Pro and $599 / month for Team.

Free has firm project, storage, and egress ceilings, and inactivity pauses make it a poor fit for services that must stay available. Pro raises those quotas and adds daily backups, but its listed retention is seven days. Team costs substantially more and is the tier with dashboard SSO and SLAs; HIPAA is an additional paid option. Enterprise uses custom pricing for its support and connectivity package.

Platforms

Supabase lists support for Android, iOS, macOS, Windows, web, API, and self-hosted deployments. Its client libraries cover JavaScript and TypeScript, Dart and Flutter, Swift, and Python, while self-hosting documentation serves teams that want to operate the platform themselves.

Who it's for

Supabase is strongest for application developers who want a relational Postgres foundation with authentication, storage, realtime features, and server-side functions in one backend. Its free plan can serve a small project or early evaluation; Pro is the more practical starting point for continuing workloads that exceed free limits or cannot accept inactivity pauses. Teams with strict growth expectations should account for manual scaling, while organizations needing SSO, SLAs, or HIPAA support should consider Team or Enterprise costs.

Pros and cons

• Pros: A Postgres database comes with every project, with extensions and platform services for auth, storage, realtime, and functions.
• Pros: Paid plans include database branching, and the platform supports point-in-time recovery and read replicas.
• Pros: Free provides 50,000 monthly active users and two active projects, giving small builds room to start without a subscription.
• Cons: Free projects pause after one week of inactivity, and the plan caps active projects at two.
• Cons: Scaling is manual, which puts growth planning and operational decisions on the team.
• Cons: Pro's listed backup retention is seven days; longer 14-day retention and SLAs start with Team at $599 / month.

Alternatives

For a managed SQL database with a free offer of 100,000 vCore seconds, 32 GB of data storage, 32 GB of backup storage, and 10 databases per subscription, consider Azure SQL Database. It is a database-focused alternative when those free database allowances are the priority.

Verdict

Choose Supabase when your application benefits from Postgres and you want auth, storage, realtime, and server-side functions gathered around it, with a free entry point and a documented self-hosting path. Look elsewhere if you need automatic scaling or a small standalone service: its scaling is manual, and its free projects can pause after inactivity. For sustained use, compare the Pro quotas with expected demand before committing.
