Feature Comparison

Feature	Fly.io	Turso
Primary Purpose	Full application deployment platform supporting Docker containers, web apps, and various databases	Specialized distributed SQLite database service focused solely on data storage and replication
Edge Distribution	Deploys entire applications as microVMs across 30+ global regions with Anycast routing	Replicates SQLite databases to edge locations with embedded replicas for low-latency reads
Database Support	Native support for PostgreSQL and Redis, plus ability to run any containerized database	Exclusively SQLite-based with libSQL enhancements, full SQLite compatibility
Deployment Model	Deploy via flyctl CLI with Docker containers converted to Firecracker VMs	Connect via SQLite-compatible drivers with native framework integrations
Use Case Scope	Complete infrastructure solution for full-stack applications including compute, networking, and storage	Database-only solution that integrates with existing application infrastructure
Developer Experience	Steeper learning curve with infrastructure management responsibilities and VM concepts	Simple adoption for SQLite users with familiar API and minimal architectural changes

Pricing Comparison

Both platforms offer generous free tiers starting at $0/month, making them accessible for small projects and experimentation. Fly.io uses pay-per-use pricing that can become unpredictable with variable traffic across compute and networking resources, while Turso's pricing is more straightforward based on storage and row operations.

Verdict

Choose Fly.io if...

Choose Fly.io if you need a complete application deployment platform with global edge distribution, want to run full-stack applications with compute and networking needs, or require flexibility to deploy any containerized workload with multiple database options.

Choose Turso if...

Choose Turso if you specifically need a distributed SQLite database with edge capabilities, want to leverage SQLite's simplicity while gaining global scale, or are building applications where low-latency data access is critical but you already have compute infrastructure in place.
