Silos is a hosted PostgreSQL platform for developers and teams building edge-first applications, SaaS products, APIs, and multi-region workloads. It provisions PostgreSQL 18 databases through a web console, API, or CLI, while supporting the PostgreSQL wire protocol. Its focus is distributed reads and usage-based infrastructure, with scale-to-zero operation, copy-on-write branching, edge replicas, WAL streaming, and browser-based development through PGLite. Integrations include Prisma, Drizzle, Kysely, Python, Node.js, and cURL.

Pricing is structured around a free entry point and paid usage. The Free plan includes scale-to-zero databases, branching, PostgreSQL 18, in-browser PGLite development, and community support. The Scale plan costs $69 per month and adds usage-based metering for compute, storage, and transfer, on-demand edge replicas, tunable per-query consistency, API and CLI access, and email support. Global costs $199 per month and adds global WAL streaming, multi-region edge replicas, higher usage allowances, and priority support. Enterprise includes committed-use discounts, dedicated support and onboarding, custom terms and invoicing, and deployment options on request.

Silos stands out where edge-oriented PostgreSQL behavior matters more than a conventional single-region setup. Developers can combine on-demand read replicas, per-query consistency controls, WAL-based change-data capture, and a SQL console with metrics and replica monitoring. Branching and scale-to-zero also suit development workflows and workloads with idle periods. However, Silos is described as pre-GA, and automatic primary promotion is on the roadmap. Teams that need a more established high-availability operating model should evaluate alternatives. Silos is a strong fit for teams designing serverless, globally distributed applications and a less suitable choice for buyers prioritizing mature failover automation above edge distribution.

Silos pros and cons

  • Where it wins
    • Scale-to-zero databases and copy-on-write branching
    • Edge replicas with tunable per-query consistency
    • API, CLI, SQL console, and browser-based PGLite development
  • Where it doesn't
    • The platform is described as pre-GA
    • Automatic primary promotion is still on the roadmap
    • Global and Enterprise capabilities require higher-tier commitments
