Apache Cassandra
Prisma Postgres

No description of Apache Cassandra yet.

Prisma Postgres is a serverless PostgreSQL database built for the way developers and AI agents ship today. It provisions a new database in under a second, scales to zero with no idle pausing (so you never pay for or wait on a cold instance), and gives you 50 databases on the free tier, or 1,000...

Features and specs

What each product offers, as listed by its team.

Apache Cassandra 6 features
Prisma Postgres 12 features
  • Scalability
    Apache Cassandra is designed for linear scalability and can handle large volumes of data across many commodity servers without a single point of failure.
  • High Availability
    Cassandra ensures high availability by replicating data across multiple nodes. Even if some nodes fail, the system remains operational.
  • Performance
    It provides fast writes and reads by using a peer-to-peer architecture, making it highly suitable for applications requiring quick data access.
  • Flexible Data Model
    Cassandra supports a flexible schema, allowing users to add new columns to a table at any time, making it adaptable for various use cases.
  • Geographical Distribution
    Data can be distributed across multiple data centers, ensuring low-latency access for geographically distributed users.
  • No Single Point of Failure
    Its decentralized nature ensures there is no single point of failure, which enhances resilience and fault-tolerance.

Possible disadvantages

  • Complexity
    Managing and configuring Cassandra can be complex, requiring specialized knowledge and skills for optimal performance.
  • Eventual Consistency
    Cassandra follows an eventual consistency model, meaning that there might be a delay before all nodes have the latest data, which may not be suitable for all use cases.
  • Write-heavy Operations
    Although Cassandra handles writes efficiently, write-heavy workloads can lead to compaction issues and increased read latency.
  • Limited Query Capabilities
    Cassandra's query capabilities are relatively limited compared to traditional RDBMS, lacking support for complex joins and aggregations.
  • Maintenance Overhead
    Regular maintenance tasks such as node repair and compaction are necessary to ensure optimal performance, adding to the administrative overhead.
  • Tooling and Ecosystem
    While the ecosystem for Cassandra is growing, it is still not as extensive or mature as those for some other database technologies.
  • Provisioning
    Sub-second. Instant database via dashboard, API, or create-db.prisma.io
  • Free Tier
    100k operations, 500 MB storage, 50 databases. No time limit
  • Scale to Zero
    No idle pausing. Free databases are never suspended for inactivity.
  • Pricing model
    Operations-based. Pay per query, not compute hours or provisioned resources
  • Connection Pooling
    Built in, no separate pooler needed
  • Caching
    Global edge caching layer for query responses
  • Backups
    Automated daily backups with point-in-time recovery
  • AI Agent Support
    MCP server, partner provisioning API, no-auth instant databases
  • ORM Integration
    Native Prisma ORM support. Migrations, type-safe queries, Prisma Studio
  • Connectivity
    Direct TCP connections. Works with any Postgres tool or ORM
  • Spend Control
    Hard spend limits on by default on every paid plan
  • Databases Per Plan
    1,000 on Starter.

Questions & Answers

As answered by people managing Apache Cassandra and Prisma Postgres.

Why should a person choose your product over its competitors?

Prisma Postgres's answer:

Prisma Postgres gives you serverless Postgres without the usual tradeoffs. It removes cold starts, so scaling to zero costs you nothing on the next request. Its free tier of 50 databases (and up to 1,000 on paid tiers) is far more generous than competitors that cap free plans at one or two. It can colocate with Prisma Compute for microsecond latency, which standalone Postgres hosts cannot match. And because it is real Postgres, there is no proprietary query layer and no lock-in, so you can move your data and schema out at any time.

How would you describe the primary audience of your product?

Prisma Postgres's answer:

Prisma Postgres is built for AI agents that generate and deploy applications. Sub-second provisioning, zero cold starts, and up to 1,000 databases let an agent spin up a fresh, isolated database for every generated app, preview, or run without cost or setup friction. It equally serves the developers and teams behind those agents, building web and backend apps in TypeScript and JavaScript on serverless and edge platforms, who want managed Postgres with no operational overhead.

What's the story behind your product?

Prisma Postgres's answer:

Prisma is the company behind Prisma ORM, one of the most widely used database toolkits in TypeScript and JavaScript. Prisma Postgres grew out of watching developers pair that ORM with databases that were slow to provision, costly at idle, and hurt by cold starts. It launched in early access in October 2024 and reached general availability in February 2025, bringing serverless Postgres with sub-second provisioning, zero cold starts, and native Prisma ORM integration, now built for the era of AI agents that create and deploy apps at scale.

What makes your product unique?

Prisma Postgres's answer:

Prisma Postgres is serverless PostgreSQL that provisions in under a second, scales to zero with no idle billing, and has zero cold starts. It is built to run many databases at once: 50 on the free tier and up to 1,000 on paid tiers, ideal for a database per branch, preview, or AI agent run. It can be colocated with Prisma Compute so your application logic runs on the same machine as the database for microsecond latency. Being standard Postgres, it has no lock-in and integrates natively with Prisma ORM.

Which are the primary technologies used for building your product?

Prisma Postgres's answer:

Prisma Postgres runs standard PostgreSQL on a unique architecture built with unikernels (lightweight, single-purpose VMs) on bare-metal infrastructure, with a global caching and connection-pooling layer built on Cloudflare's edge network. This is what enables sub-second provisioning, zero cold starts, and scale-to-zero. It integrates natively with Prisma ORM (TypeScript) and supports direct TCP connections for any Postgres client.
