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 | Vfly Script -Fly 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.
