Skill UI

This skill guides users through setting up robust, production-grade infrastructure on Fly.io. It covers creating and connecting to Fly Postgres clusters for reliable data storage, provisioning persistent NVMe Volumes for durable file storage, and configuring private internal networking (6PN) for secure service-to-service communication. It is essential for modern microservices requiring stable databases and persistent state.

This guide demonstrates how to deploy a minimal "Hello World" application to the Fly.io platform. It covers two primary deployment methods: using the simple `flyctl` Command Line Interface (CLI) for quick setup, and utilizing the advanced Machines API for programmatic deployment. This skill is ideal for beginners starting a new Fly.io project, or for implementing robust, globally distributed edge compute infrastructure.

This guide provides comprehensive strategies to significantly boost the performance and reliability of applications deployed on Fly.io. Techniques covered include eliminating cold starts (auto-stop/start), right-sizing Virtual Machines based on workload demands, implementing multi-region deployment for low latency, and optimizing connection pooling for databases. Essential for scaling modern SaaS applications.

This comprehensive checklist guides developers through hardening their application for production deployment on Fly.io. It covers critical aspects such as multi-region redundancy, secure secret management, robust health checks, graceful shutdown procedures, and automated rollback mechanisms. Use it to ensure your edge-deployed application is highly available, reliable, and resilient against common operational failures.

This utility provides comprehensive solutions for managing rate limits when interacting with the Fly.io Machines API. It implements advanced patterns like Token Bucket rate limiting, exponential backoff, and request batching. This ensures that automation scripts remain robust and reliable, even during high-churn operations such as large-scale deployments or auto-scaling events, preventing common 429 throttle errors.

A comprehensive TypeScript SDK providing production-ready patterns for interacting with the Fly.io Machines REST API. It includes a typed client for managing the entire machine lifecycle—creation, state polling, and deletion—across multiple global regions. Features like robust error handling, rate-limit retries, and deployment builders ensure reliable multi-region orchestration for edge computing applications.

This comprehensive guide provides essential security best practices for deploying applications on Fly.io. It covers critical areas such as secrets management, private networking using WireGuard, securing TLS certificates, and properly scoping deploy tokens. The included functions demonstrate how to validate API tokens, verify webhook signatures, and validate deployment configurations to mitigate common cloud and application-level vulnerabilities.

This comprehensive guide provides step-by-step instructions for migrating and upgrading services on the Fly.io platform. It details critical processes such as migrating applications from Apps v1 (Nomad) to v2 (Machines), upgrading the flyctl CLI, performing major Postgres database version upgrades, and executing region migrations. Essential for maintaining and modernizing cloud infrastructure.

This skill establishes CI/CD pipelines for complex financial workflows, including expense tracking, budget alerts, and compliance reporting for startup accounting (Fondo). It runs comprehensive unit and integration tests on every pull request and main branch merge, validating data transformation, monitoring filing deadlines, and ensuring live API connectivity to maintain financial data integrity and compliance.

Collects comprehensive diagnostic information for Fondo support tickets. This bundle checks API connectivity status, filing compliance, integration health (bank/payroll), and detects reconciliation discrepancies. Ideal for troubleshooting complex financial sync errors, tax filing issues, and general platform failures.

A comprehensive workflow for developing and testing financial applications integrated with Fondo. It enables developers to simulate or parse real Fondo exports (CSV/Accounting tools) locally, providing a fast feedback loop for building dashboards, calculating R&D credits, and analyzing burn rates without relying on live API connectivity. Supports mock data for rapid iteration and real export parsing for production validation.

This utility helps manage API rate limits when building parallel integrations with multiple financial providers (Gusto, QuickBooks, Plaid, Stripe). It implements a token bucket algorithm and robust retry strategies to prevent shared-limit conflicts and ensure reliable data synchronization during high-volume processes like month-end reconciliation.
