Teams look past Supabase when the bill depends on compute size and usage, when the free plan pauses an idle project, or when backups, SSO and log drains sit on paid tiers. Most move to Neon or plain PostgreSQL to keep Postgres, to Firebase for a Google backend, or to PlanetScale and CockroachDB for scale.
Visibility in our rankings can be paid for. Payment moves a vendor's position within
the shortlist; it never adds a vendor, and it never changes a word of the review or of this page. The first three alternatives
go to challengers, vendors outside the best-known brands in a category, wherever the category has them; the
established names follow in their ranked order. How it works:
placement disclosure · editorial process.
What each alternative does differently
1. Neon
Serverless Postgres with scale to zero and branches · United States
Serverless Postgres with scale to zero and branching, now with managed auth, object storage and functions on its own pricing page. Billing is per compute-hour and per gigabyte-month, with no flat plan fee. Realtime is still labeled beta, so the bundle is thinner than Supabase.
Switch from Supabase if you want Postgres billed by compute-hour with branches, and can live with a younger backend bundle.
Pricing: Free at $0 (100 projects, 1 GB storage per project); Launch usage-based at $0.106 per CU-hour and $0.35 per GB-month; Scale at $0.222 per CU-hour. (free plan)

2. Firebase
Google's app backend with document databases and auth · United States
Google's app backend built on document databases rather than Postgres. The Spark plan needs no payment method and Blaze bills beyond quotas through Google Cloud. Moving means rewriting queries from SQL to document access, and Supabase documents a Firestore migration path in the other direction.
Switch from Supabase if your app is mobile first and you accept a document model tied to Google Cloud billing.
Pricing: Spark plan at no cost with daily quotas (Firestore: 1 GiB stored, 50,000 reads and 20,000 writes per day); Blaze pay-as-you-go beyond that, billed through Google Cloud. (free plan)

3. PostgreSQL
The open source relational database behind half this list · Canada
The database itself, with no auth service, API layer or storage attached. The code is free under the PostgreSQL licence, so you pay only for servers and for whoever runs them. Backups, upgrades and failover become your work, and so does every feature Supabase bundled around it.
Switch from Supabase if you have the people to run servers and want no vendor between you and Postgres.
Pricing: Free to download and use under the PostgreSQL License, with no vendor charge; hosting and operations are your own cost. (open source)

4. PlanetScale
Managed MySQL-compatible Vitess and Postgres with sharding · United States
A managed database platform that sells Postgres and MySQL-compatible Vitess clusters. Pricing is by resources, from $5 per month for a single node, and no free plan is listed. It offers no bundled login or file storage, so authentication has to come from elsewhere.
Switch from Supabase if your problem is database scale or high availability, not the backend features around it.
Pricing: Resource-based billing: PlanetScale Postgres single node from $5 per month, Metal with local NVMe from $50 per month, high availability as one primary plus two replicas; no free plan. (none)

5. CockroachDB
Distributed SQL that survives regional failures · United States
A distributed SQL database that speaks the Postgres wire protocol, with multi-region clusters and a 99.999% availability target on the top edition. Billing is per vCPU-hour, and the cost example on its pricing page is above $1,500 per month. A 30-day trial replaces a free plan.
Switch from Supabase if you need Postgres-style SQL that keeps running when a whole region fails.
Pricing: Standard at $0.092 per vCPU-hour (about $203 per month for 2 vCPU and 100 GB); Mission Critical at $0.162 per vCPU-hour; 30-day trial with $400 credit. (free trial)

6. MongoDB
Document database with a managed cloud service · United States
A document database, so the schema and queries change from tables and SQL to JSON-like documents. Atlas has a free 512 MB cluster, Flex up to $30 per month and Dedicated from $56.94. The self-managed Community Edition is under the Server Side Public License.
Switch from Supabase if your data is naturally nested documents and you are willing to leave relational SQL.
Pricing: Atlas Free at $0 (512 MB); Flex up to $30 per month (5 GB); Dedicated from $0.08 per hour, starting at $56.94 per month; Community Edition is free to download. (free plan)

7. Amazon DynamoDB
Serverless NoSQL key-value database from AWS · United States
A serverless key-value and document store inside AWS. It bills per read and write request or per provisioned capacity, plus storage, and a free tier exists. The unit prices render client-side, so we cannot quote them. Joins and ad hoc SQL are not what it is for.
Switch from Supabase if your access patterns are simple key lookups at high volume and you already run on AWS.
Pricing: Billed per read and write request unit on demand, or per provisioned capacity unit per hour, plus storage; a free tier exists. The unit prices render client-side on the page we fetched. (free plan)

8. MariaDB
MySQL-compatible open source database with paid platforms · United States
A MySQL-compatible server, so a move from Postgres is a data and syntax migration. Community Server is free under GPL version 2, and the cloud and enterprise products are priced through sales on the pages we fetched. No login, API or storage layer comes with it.
Switch from Supabase if your stack is MySQL-flavored and you want an open source server with paid support available.
Pricing: Community Server is free under GPL version 2; MariaDB Cloud and Enterprise Platform pricing is handled through sales on the pages we fetched. (open source)

9. Redis
In-memory data store for caches, sessions and queues · United States
An in-memory store used for caches, sessions and queues rather than a system of record. Cloud has a free 30 MB tier, Essentials from about $5 per month and Pro with a $200 monthly minimum. It complements a main database more often than it replaces one.
Switch from Supabase if the part of Supabase you use is realtime or session state and you can keep the main data elsewhere.
Pricing: Redis Cloud Free at $0 (30 MB); Essentials from $0.007 per hour (about $5 per month); Pro from $0.014 per hour with a $200 monthly minimum. (free plan)

10. SQLite
Public domain database library in a single file · United States
An embedded library, not a hosted service: the database is one file inside your application, in the public domain. There is no network server, no dashboard and no authentication. It costs nothing and removes hosting, and it also removes concurrent multi-server access.
Switch from Supabase if you build a single-server or local app and want no database service to pay for.
Pricing: Free, dedicated to the public domain; optional paid support and SQLite Consortium membership are sold by Hwaci. (open source)

11. ClickHouse
Column store for real-time analytics at large scale · United States
A column store for analytics, not for app transactions. Cloud bills storage at $25.30 per terabyte-month and compute per unit-hour, with a 30-day trial. It answers questions over huge event tables quickly, and it is a poor home for user rows that change often.
Switch from Supabase if the workload is dashboards and event analytics and Postgres is too slow for it.
Pricing: ClickHouse Cloud Basic and Scale bill storage at $25.30 per TB per month and compute from $0.2181 per unit-hour; 30-day trial with $300 in credits. (free trial)
