This workflow provides comprehensive administrative tools for managing Replit teams and organizational assets. It allows users to manage team members (invite, remove, assign roles), audit user seats, promote deployments from dev to production, configure custom domains, and perform bulk audits on Repls and team activity logs. Ideal for organization owners needing to maintain compliance and optimize team resources.

This comprehensive guide provides a detailed framework for optimizing spending across Replit services. Learn how to conduct a thorough billing audit, right-size deployment resources (Autoscale vs. Reserved VM), manage data egress costs, optimize team seat licenses, and clean up idle resources. Essential for controlling cloud spending and ensuring efficient resource allocation in any development workflow.

This guide identifies and explains common anti-patterns and critical pitfalls encountered when building applications on the Replit platform. Topics include data persistence, secret management, networking bindings, and environment configuration. Use this resource when conducting code reviews, onboarding new developers, or auditing existing Replit applications for best practices.

A comprehensive guide for optimizing application performance on Replit. Covers critical areas such as reducing cold start times, managing memory consumption, optimizing Nix environment dependencies, accelerating build processes, and ensuring database connection efficiency. Use this guide when facing slow startups, resource limits, or deployment slowdowns.

This skill provides comprehensive guardrails for securing Replit-hosted applications. It covers critical security policies including preventing hardcoded secrets, implementing resource usage limits (CPU/Memory), enforcing endpoint authentication, and ensuring proper deployment configuration. Use this when you need to harden a Replit app for production or audit its security posture.

This guide teaches developers how to implement robust rate limiting and handle resource quotas for applications hosted on Replit. It covers monitoring Key-Value database usage, implementing middleware for API rate limiting (using Express), and utilizing exponential backoff and request queuing patterns to ensure application stability and prevent service degradation when hitting resource limits (e.g., 429 errors).
