Serverless Postgres, done right
The first multi-tenant, fully compatible, open-source Postgres backend for agents, developers, and builders who vibe. Deploy extremely cost-optimized and reliable micro DBs with consistent performance that autoscale. Postgres architected with true multi-tenancy over object storage to support high availability, instant provisioning and millions of 1¢ DBs with 20-50% lower compute cost.
$0 when idle
No charges when your database isn't being used. Unlike other "serverless" solutions, we mean it—zero dollars for idle time.
1¢ databases
Create databases for pennies. No minimum commitment, no reserved capacity. Start small, scale infinitely.
Pay per CPU-ms
Precise billing by CPU milliseconds. No rounding up to hours or minutes. Pay for exactly what you use, nothing more.
Our multi-tenant architecture shares compute resources across databases while maintaining complete isolation and security. This allows us to offer true serverless pricing without the traditional overhead costs of dedicated instances.
Built for developer and agent workflows
Developer-first features designed for modern workflows. Fork, time travel, preview, and provision databases instantly—no waiting, no complexity.
Instant fork
Clone entire databases in milliseconds. Create isolated environments for testing, development, or AI agents without copying data.
Time travel
Query any point in your database's history. Restore to previous states, recover data, or analyze changes over time.
Preview environments
Automatic preview databases for every pull request. Test schema changes and migrations in isolation before merging.
Instant provisioning
New databases ready in under a second. No waiting, no setup wizard, no configuration. Just instant, production-ready Postgres.
Built for autonomous agents
AI agents can programmatically create, fork, and manage databases without human intervention. Perfect for multi-tenant SaaS, per-user databases, or dynamic environments that scale with your agent workflows.
Provisioned compute
When you need dedicated resources, switch to provisioned compute instantly. Zero downtime migrations, vertical scaling, and enhanced isolation—all on demand.
Vertical scaling
Scale compute resources up or down instantly as your needs change. From small workloads to enterprise scale, adjust on the fly with zero downtime.
Enhanced isolation
Move from shared multi-tenant to dedicated single-tenant infrastructure. Get predictable performance and complete resource isolation for production workloads.
Production apps with consistent high load benefit from dedicated resources.
Meet regulatory requirements that mandate dedicated infrastructure.
Guaranteed performance without the variability of shared resources.
Architecture Overview
Understanding Postgres internal architecture with dual backend processes, complete isolation, query processing pipelines, and shared resource management.
Each database connection spawns a dedicated backend process (FIG 1.0, FIG 2.0) with isolated memory management, ensuring complete independence and fault tolerance.
Shared buffer pool, WAL buffer, and commit log are managed by the unified Storage Manager, providing efficient resource utilization across all connections.
Postgres backend to build and scale your applications faster
More than just a database. Nile comes with built-in authentication, vector embeddings, hosted MCP server, and AI agent capabilities—everything you need to ship faster.
Optional auth
Drop-in authentication with user management, sessions, JWT tokens, and MFA. Skip weeks of auth implementation and security concerns.
Vector embeddings
Native pgvector support for semantic search, RAG, and AI applications. Store and query embeddings at scale without separate vector databases.
Hosted MCP
Model Context Protocol server hosted and managed for you. Connect AI agents to your database with pre-built tools and secure access controls.
AI agent
Built-in AI agent that understands natural language queries and translates them to SQL. Query your database, manage data, and build insights conversationally.
Database, auth, vectors, and AI in a single platform
One SDK for all features with consistent patterns
Skip months of infrastructure setup and integration
