Sylphx vs Fly.io
Global container deployment vs. full-stack SaaS platform
Fly.io is loved by developers for its fast global deployments and low-level control over machine sizing and regions. But it's infrastructure — you still wire up every application service yourself. Sylphx delivers the same deployment power with 18 additional managed services built in.

Key differences
Managed services vs. DIY infrastructure
Fly.io gives you VMs in 30+ regions — fast, flexible, developer-friendly. But you still need to add auth (Clerk?), billing (Stripe?), a database (Neon? Turso?), analytics, and more. Sylphx bundles 19 services so you ship product features instead of integrating tools.
Global deployment — both do it well
Fly.io pioneered affordable global deployment with Anycast networking and hardware-isolated VMs. Sylphx's Deploy service matches this for application workloads. The difference: Sylphx services (database, KV, search) are also globally distributed by default.
Developer experience
Fly.io requires learning flyctl, Dockerfiles, and machine configuration. Sylphx's `npx create-sylphx-app` bootstraps a full-stack project with every service pre-configured. No infra expertise required.
Pricing model
Fly.io is pure usage-based (VM hours, bandwidth, storage) — predictable for compute but you pay for idle machines. Sylphx charges per-service usage (API calls, storage, events) with zero cost when idle. Scale to zero automatically.
