All 3 PlanetScale alternatives
Compared: open-source alternatives to PlanetScale
| Alternative | Best for | Standout | Biggest weakness | Learning curve | Price |
|---|---|---|---|---|---|
| PlanetScalereference | teams needing a managed, horizontally-scalable MySQL (Vitess) or Postgres database with Git-style branching workflows, who don't need a permanent free tier | Database branching — copy-on-write schema and data branches for testing migrations — paired with non-blocking, zero-downtime schema changes on both its Postgres and Vitess (MySQL-compatible) offerings. | PlanetScale eliminated its free Hobby tier in April 2024, a widely-criticized move that pushed small and side projects onto paid plans starting at a $5/month minimum, with production-grade high-availability tiers starting significantly higher and metal tiers running into the thousands per month. | Moderate | From $5/mo |
| Neon | developers who want instant, low-cost database branching for every pull request or preview deployment without provisioning full new Postgres instances | Instant copy-on-write database branching that forks a full production dataset in seconds, paired with scale-to-zero compute billing so idle branches cost nothing. | Paid tiers are pure usage-based billing with no flat monthly price, so cost is harder to predict up front than a fixed-price competitor, and extra branches beyond the included count cost $1.50/branch-month, which adds up for teams branching aggressively per pull request. | Low | Free |
| Supabase | developers who want a Postgres-based backend (auth, storage, realtime, auto-generated APIs) they can self-host later, rather than committing to a proprietary NoSQL platform like Firebase | Auto-generated REST, GraphQL, and Realtime APIs derived straight from a project's Postgres schema, with Row Level Security enforcing per-row authorization at the database layer instead of in application code. | Pricing beyond the $25/month Pro base is usage-based and billed per project rather than per account, so teams running multiple projects or exceeding the 100,000 MAU / 250GB egress limits can see invoices climb well past the advertised starting price. | Moderate | Free tier · paid from $25/mo |
PlanetScale
Neon
Supabase1.Neon — best PlanetScale alternative for developers who want instant, low-cost database branching for every pull request or preview deployment without provisioning full new Postgres instances
Neon is the best PlanetScale alternative for developers who want a genuinely free tier for Postgres branching workflows, since PlanetScale eliminated its free Hobby tier entirely in April 2024 and now starts every database at $5/month minimum. Neon's Free plan includes 100 compute-hours and 0.5 GB storage per project with no credit card required, plus 10 branches per project at no cost, while PlanetScale's cheapest tier, a single-node non-HA Postgres database, still costs $5/month with no free equivalent. Neon holds a 5/5 rating from 82 Product Hunt reviews, more review volume than PlanetScale's single 4/5 Capterra review. Both platforms share database branching as their signature feature: Neon's instant, copy-on-write branching forks a full production dataset in seconds, similar in spirit to PlanetScale's own branching workflow, but Neon's scale-to-zero compute billing means idle branches and dev databases cost nothing when not in use, unlike PlanetScale's flat per-node pricing that runs whether or not the database sees traffic. PlanetScale remains the better choice for teams that specifically want a MySQL-compatible, horizontally-shardable database: Neon's Launch and Scale tiers are pure usage-based billing with no flat monthly price, making cost harder to predict up front, and extra branches beyond the included count cost $1.50/branch-month, which can add up for teams branching aggressively per pull request.
Compared to PlanetScale: genuinely free tier with 100 compute-hours and 10 branches vs PlanetScale's $5/month minimum with no free tier since April 2024, 5/5 rating from 82 Product Hunt reviews vs PlanetScale's single 4/5 Capterra review, scale-to-zero compute billing vs PlanetScale's flat per-node pricing
Wins:Free tier requires no credit card and includes 100 compute-hours plus 10 branches per project, unlike PlanetScale's $5/month minimum since dropping its Hobby tier in April 2024 · 5/5 rating from 82 Product Hunt reviews, more review volume than PlanetScale's single 4/5 Capterra review · Scale-to-zero compute means idle branches and dev databases cost nothing when not in use, unlike PlanetScale's flat per-node pricing
Loses:Postgres only, not MySQL-compatible, unlike PlanetScale's Vitess (MySQL-compatible) product line · Paid Launch and Scale tiers are pure usage-based billing with no flat monthly price, harder to predict than PlanetScale's flat per-node tiers · Extra branches beyond the included count cost $1.50/branch-month, which can add up for teams branching per pull request
Pros
- Instant database branching copies a full dataset in seconds instead of requiring a new server provision.
- Scale-to-zero compute means idle branches and dev databases cost nothing when not in use.
- Fully Postgres-compatible, so existing drivers, ORMs, and extensions work without changes.
- Free tier requires no credit card and includes 100 compute-hours plus 10 branches per project.
Cons
- Usage-based pricing with no flat monthly rate makes budgeting harder to predict than fixed-price competitors.
- Extra branches beyond the included count cost $1.50/branch-month, which can add up for teams that branch per pull request.
- Free tier storage is capped at 0.5 GB per project, small for anything beyond prototyping.
- Scale-to-zero introduces a cold-start delay when a suspended compute branch wakes up, which can affect latency-sensitive workloads.
Pricing: Free — $0/month (Free, 100 compute-hours, no credit card) vs PlanetScale's $5/month minimum (single-node Postgres, non-HA) since PlanetScale's free tier ended in April 2024 (verified undefined NaN, NaN)
2.Supabase — best PlanetScale alternative for developers who want a Postgres-based backend (auth, storage, realtime, auto-generated APIs) they can self-host later, rather than committing to a proprietary NoSQL platform like Firebase
Supabase is the best PlanetScale alternative for developers who want a full backend, authentication, storage, realtime sync, and edge functions, bundled with their Postgres database rather than PlanetScale's database-only product. Supabase's Free plan covers up to 2 active projects with a 500MB database and 50,000 monthly active users at $0/month, a genuinely free entry point that contrasts with PlanetScale's $5/month minimum since it eliminated its free Hobby tier in April 2024. Supabase holds a 5.0/5 rating from 861 Product Hunt reviews, by far the largest review base of any product in this comparison, well above PlanetScale's single 4/5 Capterra review. Supabase's core stack, Postgres, PostgREST, GoTrue auth, Realtime, and Storage, is Apache-2.0 licensed and self-hostable from a GitHub repository with more than 108,000 stars, giving teams the same self-hosting freedom PlanetScale's Vitess line offers but with authentication and storage included rather than sold separately. PlanetScale remains the better choice for teams that specifically need a MySQL-compatible, horizontally-shardable database with PlanetScale's signature branching workflow across both Vitess and Postgres product lines: Supabase's Pro tier at $25/month bills compute per project rather than per account, so teams running multiple projects or exceeding the 100,000 MAU limit can see invoices climb well past the advertised starting price.
Compared to PlanetScale: full backend (auth, storage, realtime, edge functions) bundled with Postgres vs PlanetScale's database-only product, genuinely free tier at $0/month vs PlanetScale's $5/month minimum since April 2024, 5.0/5 rating from 861 Product Hunt reviews vs PlanetScale's single 4/5 Capterra review
Wins:Free tier covers 2 active projects with a 500MB database and 50,000 MAU at $0/month, unlike PlanetScale's $5/month minimum since April 2024 · 5.0/5 rating from 861 Product Hunt reviews, by far the largest review base of any product in this comparison · Bundles authentication, S3-compatible storage, realtime sync, and edge functions with the database, features PlanetScale's listing doesn't offer
Loses:Postgres only, not MySQL-compatible, unlike PlanetScale's Vitess (MySQL-compatible) product line and its signature branching workflow · Compute is billed per project on the $25/month Pro tier, so accounts running several projects stack recurring charges beyond the flat fee · Free-tier projects pause automatically after 1 week of inactivity
Pros
- Full Postgres database rather than a proprietary NoSQL store, so existing SQL skills and extensions like pgvector and PostGIS carry over directly.
- Auto-generates REST, GraphQL, and Realtime APIs from the schema, with Row Level Security for per-row authorization.
- Apache-2.0-licensed core stack is self-hostable, avoiding hard vendor lock-in.
- Free tier includes unlimited API requests, 50,000 monthly active users, and a 500MB database with no time limit on the account.
Cons
- Compute is billed per project, so accounts running several projects stack recurring charges beyond the flat $25/month Pro fee.
- MAU overage ($0.00325/user past 100,000) and egress overage ($0.09/GB past 250GB) can produce unpredictable invoices at scale.
- Free-tier projects pause automatically after 1 week of inactivity.
- Row Level Security has a steeper learning curve than Firebase's simpler client-side security rules for teams new to SQL.
