# Replit Rate Limits ## Overview Understand and work within Replit's resource limits: Key-Value Database size caps, Object Storage quotas, deployment compute budgets, and egress allowances. Implement rate limiting in your own app for production safety. ## Prerequisites - Replit account with active Repls - Understanding of your current resource usage - For rate limiting: Express or Flask app ## Replit Platform Limits ### Key-Value Database | Limit | Value | |-------|-------| | Total storage | 50 MiB (keys + values combined) | | Maximum keys | 5,000 | | Key size | 1,000 bytes | | Value size | 5 MiB per value | ### Object Storage (App Storage) | Limit | Value | |-------|-------| | Object size | Configurable per bucket | | Bucket count | Per Repl (auto-provisioned) | | Rate | Throttled at high request volume | ### PostgreSQL | Limit | Value | |-------|-------| | Storage | Plan-dependent (1-10+ GB) | | Connections | Pooled, plan-dependent | | Dev + Prod | Separate databases auto-provisioned | ### Deployments | Resource | Autoscale | Reserved VM | |----------|-----------|-------------| | Scale behavior | 0 to N based on traffic | Always-on, fixed size | | Min cost | Pay per request | $0.20/day (~$6.20/month) | | Max resources | Plan-dependent | Up to 4 vCPU, 16 GiB RAM | | Egress | $0.10/GiB over allowance | $0.10/GiB over allowance | ## Instructions ### Step 1: Monitor KV Database Usage ```typescript // Check how close you are to KV limits import Database from '@replit/da...
