Explains the primary/replica architecture where all writes go to the primary and reads can be served from replicas. Dives into PostgreSQL internals including the Write-Ahead Log (WAL), log sequence numbers, heap files, and index files, and how replicas use WAL streaming over a persistent TCP connection to stay in sync. Also touches on eventual consistency trade-offs and the added complexity and cost of running replicas. 50 3 2. 2 [](https://daily.dev/posts/i-m-working-on-a-self-hosting-cli-tool-b3mgg0e28 "I'm working on a self hosting cli tool") Video Web Dev Cody · 13w I'm working on a self hosting cli tool A developer shares a work-in-progress CLI tool called Launchpad, inspired by Fly.io, that lets you deploy applications to self-hosted AWS EC2 instances using a TOML config file. The tool automates spinning up VMs, building and pushing Docker containers to ECR, configuring an edge router via Caddy, and supports rolling deployments with zero downtime. The project was built almost entirely through AI-assisted coding (Claude Code) with the developer making architectural decisions rather than writing code directly. The post also reflects on career growth through side projects and questions the viability of traditional educational YouTube content in the age of LLMs. 24 6 3. 3 [](https://daily.dev/posts/most-developers-overcomplicate-database-scaling-otg6bhltl "Most Developers Overcomplicate Database Scaling") Video Web Dev Cody · 12w Most Developers Overcomplicate Database Scaling A practical overview of database scaling strategies, focused primarily on PostgreSQL. Covers seven approaches in order of complexity: vertical scaling, proper indexing, connection pooling (with PgBouncer), read replicas, caching with Redis/Memcached, data partitioning, and query optimization with EXPLAIN ANALYZE. The author emphasizes that most developers — especially those at startups or on side projects — overcomplicate this and should start with vertical scaling and managed database services like AWS RDS or PlanetScale before reaching for more complex solutions. 13 1 [See all Web Dev Cody archives](/sources/webdevcody/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/webdevcody/best-of/2026/06#page","url":"https://daily.dev/sources/webdevcody/best-of/2026/06","name":"Best Web Dev Cody Posts — June 2026","description":"The most upvoted Web Dev Cody posts from June 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/webdevcody/best-of/2026/06#items","numberOfItems":3,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/postgres-replicas-explained-utnyeyxzu","name":"Postgres Replicas Explained"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/i-m-working-on-a-self-hosting-cli-tool-b3mgg0e28","name":"I'm working on a self hosting cli tool"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/most-developers-overcomplicate-database-scaling-otg6bhltl","name":"Most Developers Overcomplicate Database Scaling"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Web Dev Cody","item":"https://daily.dev/sources/webdevcody"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/webdevcody/best-of"},{"@type":"ListItem","position":5,"name":"June 2026"}]}]} ```
