Essential Developer Tools and Productivity Software

The right tools eliminate friction from your daily engineering workflow. This page collects the software, online platforms, and resources used throughout this knowledge base — from database GUI clients to algorithm practice sites and diagramming tools.

Development

Editors, terminals, API clients, and version control GUIs.

Database Tools

GUI clients for MySQL, Redis, and Elasticsearch.

Diagramming

Tools for architecture diagrams, flowcharts, and documentation.

Learning Resources

Algorithm platforms, reference sites, and courses.

Development Tools

Tool	Purpose	Notes
VS Code	General-purpose editor	Excellent Go, Java, and Markdown support via extensions
IntelliJ IDEA	Java/Spring development	Best-in-class refactoring and Spring Boot integration
GoLand	Go development	JetBrains IDE purpose-built for Go
iTerm2 / Warp	Terminal (macOS)	Split panes, search, AI autocomplete (Warp)
Postman / Insomnia	API testing	GUI clients for testing REST and gRPC endpoints
TablePlus	Database GUI	Supports MySQL, Redis, PostgreSQL, SQLite in one app

macOS Version Management

When you need to switch between versions of Go, Java, or Node.js on macOS:

# Go version management
brew install go@1.21
export PATH="/usr/local/opt/go@1.21/bin:$PATH"

# Java version management with jenv
brew install jenv
jenv add /Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home
jenv global 17

# Node version management
brew install nvm
nvm install 20
nvm use 20

Database Tools

MySQL
Redis
Elasticsearch

TablePlus — cross-platform GUI with a clean interface, supports multiple connections and SSH tunnels.MySQL Workbench — official Oracle tool with EER diagrams, query analyzer, and server management.

# Connect from CLI
mysql -h 127.0.0.1 -P 3306 -u root -p

# Common quick queries
SHOW PROCESSLIST;         -- see active connections
EXPLAIN SELECT ...;       -- query execution plan
SHOW ENGINE INNODB STATUS\G  -- InnoDB internals

RedisInsight — official Redis GUI with memory analysis, slow log viewer, and CLI.Another Redis Desktop Manager (ARDM) — lightweight open-source alternative.

# Connect from CLI
redis-cli -h 127.0.0.1 -p 6379

# Useful commands
INFO server           # server stats
MONITOR               # watch all commands in real time (dev only)
MEMORY USAGE key      # memory cost of a key
OBJECT ENCODING key   # internal encoding used

Kibana — official Elasticsearch UI with Dev Tools console for running queries.Elasticvue — browser extension for quick ES cluster inspection.

# Check cluster health
GET /_cluster/health

# Index stats
GET /my-index/_stats

# Run a query from Dev Tools
GET /my-index/_search
{
  "query": { "match": { "title": "golang" } }
}
