Supabase's pricing page sells a developer backend rather than a server. The free plan gives a full Postgres database with 500 MB of database size, shared CPU with 500 MB of RAM, 50,000 monthly active users, 5 GB of egress, 5 GB of cached egress, 1 GB of file storage, unlimited API requests and community support, with two limits worth knowing: free projects are paused after a week of inactivity, and you can keep two active projects. The Pro plan is $25 a month for the first project, with additional projects from $10 a month, 100,000 monthly active users before a charge of $0.00325 each, 8 GB of disk per project before $0.125 per GB, 250 GB of egress before $0.09 per GB and 100 GB of file storage before $0.0213 per GB. Team is $599 a month and adds SOC 2 and ISO 27001, project-scoped and read-only roles, and control over backups.
TL;DR
Supabase is a Postgres platform that bundles the database with authentication, storage, realtime and vector support, at $0, $25 and $599 a month. DigitalOcean sells the pieces separately: a Droplet for $4, managed Postgres from $15, object storage from $5. Pick Supabase to stop assembling a backend; pick DigitalOcean when you want each component priced and chosen on its own.
DigitalOcean approaches the same problem from below. A managed PostgreSQL database starts at $15 a month with free daily backups and automated failover, object storage called Spaces starts at $5 a month, and a Droplet - a full Linux machine - starts at $4 a month with 512 MiB, 1 vCPU and 10 GiB of SSD. If you want authentication, you either build it, run an open-source service on the Droplet, or bolt on a third-party product; the same goes for realtime updates, file storage policies and vector search.
So the comparison is not really price per database. It is what comes with the database. Supabase ships row-level security, an auth API, storage buckets with policies, realtime channels, edge functions and vector embeddings in the same project, and the free tier is genuinely usable for a side project as long as you accept the inactivity pause. DigitalOcean gives you a managed Postgres that behaves like a managed Postgres, plus the freedom to run Redis, a queue, an application server and a cache on the same bill, and the total is only cheaper if you do not value the parts Supabase includes.
| Feature | DigitalOcean | Supabase |
|---|---|---|
| Free tier | App Platform and Functions free; Droplets from $4/mo | Full project free: 500 MB database, 50,000 MAU, 5 GB egress |
| Entry paid tier | Managed PostgreSQL from $15/mo | Pro at $25/mo, first project included |
| Mid tier | 2 GiB Droplet at $12/mo plus database | Team at $599/mo with SOC 2 and ISO 27001 |
| Database included | PostgreSQL, MySQL, MongoDB, Kafka, Caching, Valkey, OpenSearch | PostgreSQL with API access and row-level security |
| Authentication | Build it or add a service | Included, with row-level security policies |
| File storage | Spaces from $5/mo | 1 GB free, 100 GB on Pro before $0.0213 per GB |
| Egress | 500 GiB included per Droplet, then $0.01 per GiB | 5 GB free, 250 GB on Pro, then $0.09 per GB |
| Project limits | One account, as many resources as you pay for | Two active free projects; extra Pro projects from $10/mo |
| Compliance | Support plans and documentation | SOC 2 and ISO 27001 on the Team tier |
Pick DigitalOcean if
If you already have an application framework that handles auth and storage, or you need Redis, a queue, a search cluster and a worker on the same bill, DigitalOcean prices each piece separately and lets you run them wherever you like. A $15 managed Postgres plus a $6 Droplet is a cheap, flexible stack for someone who wants to own the decisions.
Pick Supabase if
If you are building a product where the database, the user accounts, the file storage and the realtime layer are the whole backend, Supabase's Pro plan at $25 a month replaces a pile of configuration. Just read the free tier's terms before you depend on it: projects pause after a week without activity, which is fine for a prototype you return to and awkward for something that must always be up.
No reviews or user ratings were gathered for this comparison. All figures come from supabase.com/pricing and digitalocean.com/pricing as published by the vendors.
For a database-backed application, largely yes: Supabase gives you Postgres, auth, storage, realtime, edge functions and vector search in one project. What it does not give you is a general-purpose machine, so background workers, unusual runtimes and third-party services still need somewhere else to run.
Supabase's free tier is cheaper if it fits: 500 MB of database, 50,000 monthly active users and 1 GB of file storage at $0, as long as you accept that inactive projects pause after a week. On paid tiers, Supabase Pro is $25 a month while DigitalOcean's managed Postgres starts at $15 a month, though you then pay separately for auth and storage.
It is paused after one week of inactivity, and the free tier allows two active projects. The database is not deleted, but you should not put an always-on production service on the free plan.
Supabase bills $0.125 per GB of disk, $0.09 per GB of egress and $0.00325 per monthly active user beyond the Pro allowances. DigitalOcean bills $0.01 per GiB of outbound transfer beyond the 500 GiB included with a Droplet, and storage at the published rate for Volumes and Spaces.
Yes, it is Postgres, which means standard drivers, extensions and dump-and-restore migrations. Moving a Supabase project to DigitalOcean's managed PostgreSQL is a logical dump and a connection-string change, not a rewrite.
