Supabase is the best database platform for most side projects because it gives you Postgres and the rest of a usable backend. Neon is the better database-first choice for serverless Postgres. PlanetScale Postgres is the better fit when operational controls and managed database reliability are the main concern.
The platforms overlap, but they do not start from the same idea. Supabase asks, "What else does your app need?" Neon asks, "How should Postgres behave for modern development?" PlanetScale asks, "How do we keep this database boring when traffic becomes exciting?"
Quick comparison
| Platform | Best for | Strongest feature | Main tradeoff |
|---|---|---|---|
| Supabase | Building a complete app quickly | Integrated auth, storage, realtime, functions, and Postgres | More platform services can mean more coupling |
| Neon | Serverless apps and database branching | Separated storage and compute with developer-friendly branches | You may assemble auth and storage separately |
| PlanetScale Postgres | Operationally demanding applications | Managed operations and traffic controls | Less of an all-in-one app backend |
Supabase is the best overall side-project platform
Supabase combines a managed Postgres database with authentication, object storage, realtime subscriptions, edge functions, APIs, logs, and a dashboard. For an indie developer, that removes several early purchasing decisions.
It is a strong choice for:
- SaaS prototypes
- Internal tools
- Mobile and web applications
- Products with user-uploaded files
- Apps that need row-level security
- Projects where one developer owns the whole stack
The database remains Postgres, and Supabase leans into Postgres features such as extensions and row-level security instead of hiding them behind a proprietary data model. The JavaScript ecosystem is large, and many starter templates already combine Supabase with Next.js and popular deployment platforms.
If the frontend host is still undecided, our Vercel versus Netlify guide covers that part of the stack separately.
In 2026 Supabase has continued expanding observability and data movement features. Some additions are alpha or beta, so check labels before treating them as production guarantees.
Why Supabase can become complicated
The all-in-one convenience creates more platform surface area. Auth configuration, storage policies, row-level security, functions, and database permissions can interact. A prototype that appears to work may still have a dangerously broad access policy.
Keep schema changes in migrations, test row-level security with multiple user roles, export data regularly, and understand how auth user records connect to your application tables.
Neon is the best serverless Postgres choice
Neon separates compute from storage and is designed for elastic, serverless Postgres. Projects can create database branches for development, previews, tests, and experiments without copying the traditional database workflow by hand.
This is particularly useful for:
- Vercel-style preview deployments
- CI environments that need isolated data
- Apps with spiky or intermittent traffic
- Teams that want database branches tied to feature branches
- Developers who prefer choosing auth and storage separately
Neon's database product is mature, but its broader Neon Backend offering entered beta in July 2026. That beta adds managed Better Auth, object storage, functions, and an AI gateway. Treat those backend services as evolving separately from the established core Postgres service.
The Neon tradeoff
A database-first product means you may still choose an authentication provider, storage service, queue, and function platform. That modularity is excellent when you care about architecture. It is extra work when you just want users to upload profile pictures before dinner.
Also test connection behavior carefully. Serverless functions can create many short-lived connections, so use supported pooling and framework guidance rather than opening a fresh direct connection for every request.
PlanetScale Postgres is best for operational control
PlanetScale built its reputation on managed database infrastructure and later added Postgres. Its Postgres product became generally available in 2025, and 2026 updates have continued to emphasize safe operations, observability, and traffic management.
Database Traffic Control, announced in March 2026, is an example of that focus. It is meant to help protect databases from bad traffic patterns and limit the blast radius of noisy workloads.
PlanetScale Postgres is a good fit for:
- A startup that expects meaningful production traffic
- A team that values database operations more than bundled app services
- Workloads where traffic isolation matters
- Developers already comfortable assembling a separate application stack
It is not the obvious winner for the fastest hobby project because Supabase bundles more and Neon has a particularly friendly serverless developer story. It becomes more interesting when the database itself is a critical production system.
Branching and preview environments
Neon has the clearest database-branching identity. A preview deployment can receive an isolated branch, then disappear when the pull request closes. That reduces the temptation to point every test at one sad shared staging database.
Supabase also supports branching workflows and local development, but developers should compare the exact plan, lifecycle, and service coverage they need. A database branch is only part of a preview environment if auth, storage, secrets, and background jobs also behave correctly.
PlanetScale's operational workflow may fit teams that treat schema and production changes with formal controls. The right choice depends on whether preview speed or production governance is the bigger problem.
Pricing traps to model
Free tiers are useful, but your future bill can depend on different meters:
- Stored data
- Compute size and active time
- Data transfer or egress
- Branch count and lifetime
- Backup retention
- Realtime connections
- Function invocations
- Storage operations
- Log retention
Create a spreadsheet for three situations: a quiet month, a normal growth month, and one accidental viral weekend. If you cannot explain which meter becomes expensive, you do not yet understand the plan.
Security checklist
Before production:
- Use separate development and production projects.
- Turn on point-in-time recovery if the plan and risk require it.
- Test an actual restore, not just the existence of a backup badge.
- Store secrets only on the server.
- Use least-privilege database roles.
- Test row-level policies as anonymous, normal, and administrative users.
- Set usage and billing alerts.
- Document how to export data and move providers.
Managed Postgres removes server maintenance. It does not remove application security or data modeling.
Final verdict
Choose Supabase for the quickest route from idea to complete application. Choose Neon when you want a flexible serverless Postgres layer with excellent branching. Choose PlanetScale Postgres when the managed database operation itself is the product you want to buy.
For a typical side project, Supabase wins. For a developer who already has preferred auth and storage services, Neon may feel cleaner. For a serious production workload with a database-focused team, PlanetScale deserves a closer operational comparison.
