log.info("User action", user_id: 123, action: "login") For transient failures, Vfly can record a deterministic execution trace and replay it locally — invaluable for serverless debugging. 5. Common Use Cases | Domain | Example Application | |-------------------------|----------------------------------------------------------------| | CI/CD Pipelines | Lightweight replacement for Bash + jq + curl in GitHub Actions| | API Glue Code | Transform, route, or authenticate requests in an API gateway | | Edge Computing | Run sensor data validation on Raspberry Pi or industrial PLCs | | Database Migrations | Versioned, idempotent schema change scripts (built-in retries) | | Webhook Handlers | Process Stripe/GitHub webhooks with minimal cold-start lag | 6. Performance Benchmarks (Approximate) | Operation | Vfly Script | Python 3.11 | Node.js 20 | |-------------------------------|-------------|-------------|------------| | Startup time (empty script) | 1.2 ms | 38 ms | 52 ms | | JSON decode (1 MB) | 3.5 ms | 8.1 ms | 4.2 ms | | HTTP GET + JSON parse | 12 ms | 29 ms | 18 ms | | Memory footprint (idle) | 2.4 MB | 18 MB | 32 MB |

1. Introduction Vfly Script (commonly known as Fly Script ) is a lightweight, high-performance scripting language and runtime environment designed primarily for automation, task orchestration, and rapid tooling in cloud-native and edge computing environments. Its name derives from "Velocity Fly," emphasizing speed and minimal overhead. return total vfly run script

If your current scripts in Bash, Python, or JavaScript feel too heavy, fragile, or slow to start, Vfly Script offers a compelling, purpose-built alternative. Note: As of early 2026, Vfly Script is an emerging technology. Always refer to the official documentation for the latest syntax, APIs, and stability guarantees.
