3 Best Free Alternatives to Supabase in 2026
By Noahlast updated pricing verified
Compared: free alternatives to Supabase
| Alternative | Best for | Standout | Biggest weakness | Learning curve | Price |
|---|---|---|---|---|---|
| Supabasereference | 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 |
| Firebase | mobile and web developers who want a fully managed backend (database, auth, hosting, functions) without provisioning or maintaining their own servers | A single integrated platform spanning database, authentication, hosting, serverless functions, crash reporting, and analytics, all provisioned and scaled automatically by Google. | Blaze-plan costs are usage-based across many separate metered services (reads/writes, bandwidth, function invocations, storage), so bills can escalate unpredictably at scale, and Firestore's proprietary NoSQL data model creates real migration lock-in compared to SQL-based backends. | Moderate | Free |
| 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 |
| Appwrite | developer teams building web, mobile, or Flutter apps that want a Firebase-style backend (auth, database, storage, functions) they can self-host for free instead of relying solely on a vendor's cloud | Fully self-hostable under a permissive BSD-3-Clause license, so teams can run the entire backend on their own infrastructure at no licensing cost instead of being locked into Appwrite's hosted cloud. | The free Appwrite Cloud tier pauses projects after a week of inactivity and offers only community support, and self-hosting shifts the operational burden (updates, scaling, backups) onto the team instead of a managed vendor, which is a real cost some reviewers note as a steeper setup than a pure SaaS backend. | Moderate | Free tier · paid from $25/mo |

Appwrite1.Firebase — best Supabase alternative for mobile and web developers who want a fully managed backend (database, auth, hosting, functions) without provisioning or maintaining their own servers
Firebase is the best Supabase alternative for mobile and web developers who want a fully managed backend without provisioning their own Postgres database. Firebase's free Spark plan requires no payment method and includes 50,000 monthly active Authentication users, 1GiB Firestore storage, and 2 million Cloud Function invocations per month, quotas comparable to Supabase's own free plan (2 projects, 500MB database, 50,000 MAU). Firebase bundles operational tooling Supabase doesn't include natively, such as Crashlytics for crash reporting, Google Analytics, and Remote Config for feature flags and A/B testing, alongside SDKs for iOS, Android, web, Flutter, Unity, and C++. Firebase holds a 4.6/5 rating from 767 Capterra reviews, a smaller sample than Supabase's 5.0/5 from 861 Product Hunt reviews. Supabase is still the better choice for teams that specifically want a SQL database: Firestore's proprietary NoSQL document model creates real migration lock-in and a steeper query-design learning curve than SQL, while Supabase's Postgres core means existing SQL skills and extensions like pgvector and PostGIS carry over directly, and its Apache-2.0-licensed stack is self-hostable, avoiding Firebase's vendor lock-in entirely.
Compared to Supabase: fully managed NoSQL backend vs Supabase's Postgres-based stack, built-in Crashlytics/Analytics/Remote Config vs none of those natively, 4.6/5 from 767 Capterra reviews vs Supabase's 5.0/5 from 861 Product Hunt reviews
Wins:Free Spark plan requires no payment method and covers 50,000 Authentication MAU, 1GiB Firestore storage, and 2 million function invocations per month · Bundles operational tooling (Crashlytics, Google Analytics, Remote Config, Performance Monitoring) that Supabase doesn't offer natively · Broad SDK coverage across iOS, Android, web, Flutter, Unity, and C++
Loses:Firestore's proprietary NoSQL document model creates migration lock-in and a steeper query-design learning curve than Supabase's SQL-based Postgres · Blaze pay-as-you-go pricing spans many separately metered services, making cost forecasting harder than Supabase's flat $25/month Pro base · 4.6/5 rating from 767 Capterra reviews, below Supabase's own 5.0/5 from 861 Product Hunt reviews
Pros
- Generous free Spark tier with no payment method required, suitable for prototypes and small apps.
- Fully managed infrastructure removes the need to provision or scale servers manually.
- Deep, well-documented SDKs across iOS, Android, web, Flutter, Unity, and C++.
- Integrated operational tooling (Crashlytics, Analytics, Remote Config) reduces the need for separate third-party services.
Cons
- Blaze pay-as-you-go pricing spans many separately metered services, making cost forecasting difficult at scale.
- Firestore's proprietary NoSQL model creates lock-in and a steeper query-design learning curve than SQL databases.
- Some reviewers report recurring bugs and instability in certain SDK versions.
- Complex security rules (Firestore/Realtime Database) require careful configuration to avoid open or over-restrictive access.
Pricing: Free — Free Spark plan (no card required), then Blaze pay-as-you-go at Google Cloud rates vs Supabase's free plan plus $25/month Pro (with $10/month compute credit included) (verified undefined NaN, NaN)
2.Neon — best Supabase 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 Supabase alternative for developers who want instant, Git-style database branching and compute that scales to zero when idle, rather than Supabase's always-provisioned project model. Neon's copy-on-write branching forks a full production dataset, schema and data, in seconds for testing migrations or preview deployments, a workflow Supabase doesn't offer natively. Neon's Free plan requires no credit card and includes 100 compute-hours and 10 branches per project, and its Launch tier bills purely on usage at $0.106 per compute-hour and $0.35 per GB-month storage with no monthly minimum, versus Supabase's flat $25/month Pro base plus overages beyond its included $10/month compute credit. Neon holds a 5/5 rating on Product Hunt from 82 reviews, a smaller sample than Supabase's own 5.0/5 from 861 Product Hunt reviews, though both are perfect scores. Supabase is still the better choice for teams that need more than a database: Neon is Postgres-only, without Supabase's bundled S3-compatible file storage, realtime websocket sync, or edge functions, and Neon's scale-to-zero compute introduces a cold-start delay when a suspended branch wakes up, which can affect latency-sensitive workloads.
Compared to Supabase: instant copy-on-write branching vs no native branching, pure usage-based pricing ($0.106/compute-hour) vs Supabase's flat $25/month Pro base, Postgres-only vs Supabase's bundled auth/storage/realtime/functions
Wins:Instant copy-on-write branching forks a full production dataset in seconds, a workflow Supabase doesn't offer natively · Scale-to-zero compute means idle branches and dev databases cost nothing when not in use · Free plan requires no credit card and includes 100 compute-hours plus 10 branches per project
Loses:Postgres-only, without Supabase's bundled S3-compatible file storage, realtime websocket sync, or edge functions · Pure usage-based billing with no flat monthly rate makes budgeting harder to predict than Supabase's $25/month Pro base · Scale-to-zero introduces a cold-start delay when a suspended compute branch wakes up, which can affect latency-sensitive workloads
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 — Free plan (100 compute-hours, no card required), then $0.106/compute-hour usage-based Launch pricing vs Supabase's free plan plus $25/month Pro (with $10/month compute credit included) (verified undefined NaN, NaN)
3.Appwrite — best Supabase alternative for developer teams building web, mobile, or Flutter apps that want a Firebase-style backend (auth, database, storage, functions) they can self-host for free instead of relying solely on a vendor's cloud
Appwrite is the best Supabase alternative for teams that want a Firebase-style backend, bundling authentication, a database, file storage, functions, and messaging, that they can self-host for free under a permissive license. Appwrite's core is BSD-3-Clause licensed with 57.1K GitHub stars, self-hostable via Docker on any Linux server at no cost, comparable in spirit to Supabase's own Apache-2.0-licensed, self-hostable core built on Postgres. Appwrite Cloud's free tier includes 2GB storage, 750,000 monthly executions, and 75,000 monthly active users, close to Supabase's free plan (500MB database, 50,000 MAU), and its Pro tier costs $25/month, matching Supabase's own $25/month Pro price exactly, though Appwrite's Pro includes 150GB storage and 3.5 million monthly executions. This data set carries no external rating for Appwrite, so its reception can't be compared numerically against Supabase's 5.0/5 from 861 Product Hunt reviews. Supabase is still the better choice for teams that specifically want a Postgres database with auto-generated REST, GraphQL, and Realtime APIs derived from the schema: Appwrite's data model isn't built around exposing a relational schema the same way, and self-hosting Appwrite shifts the operational burden of updates, scaling, and backups onto the team instead of a managed vendor.
Compared to Supabase: BSD-3-Clause self-hostable core (57.1K GitHub stars) vs Supabase's Apache-2.0 core, matching $25/month Pro tier, no external rating on record vs Supabase's 5.0/5 from 861 reviews
Wins:Fully self-hostable under a permissive BSD-3-Clause license via Docker on any Linux server at no licensing cost · Single platform bundles auth, database, storage, functions, and messaging behind one unified API · Free Appwrite Cloud tier includes 75,000 monthly active users, more than Supabase's free-plan cap of 50,000 MAU
Loses:No external rating recorded in this data set, so its reception can't be weighed against Supabase's 5.0/5 from 861 Product Hunt reviews · Free Cloud tier projects pause after a week of inactivity and get community-only support, a limitation similar to Supabase's own free tier · Doesn't auto-generate REST, GraphQL, and Realtime APIs from a relational schema the way Supabase's Postgres-based stack does
Pros
- Fully open source (BSD-3-Clause) and self-hostable for free, avoiding vendor lock-in on a core backend.
- Single platform covers auth, database, storage, functions, and messaging instead of stitching together separate services.
- Broad SDK coverage across major frontend frameworks and mobile platforms including Flutter.
- Free Appwrite Cloud tier is usable for real projects, not just a sandbox, with 75K monthly active users included.
Cons
- Free Cloud tier projects pause after a week of inactivity and get community-only support.
- Self-hosting requires managing updates, scaling, and backups yourself, shifting operational work onto the team.
- Reviewers note initial setup can be more complex than newcomers expect for a 'quick MVP' backend.
- Enterprise features (SSO, compliance certifications, SLAs) require a custom-quote plan rather than being available at a fixed price.
Pricing: Free tier · paid from $25/mo — Free to self-host, or Appwrite Cloud free tier plus $25/month Pro (150GB storage, 3.5M executions) vs Supabase's free plan plus $25/month Pro (with $10/month compute credit included) (verified undefined NaN, NaN)
