IDE and Code Editor

VS Code (Free): Our primary recommendation for most development work. Reasons: Free, extensible (massive marketplace), lightweight startup, excellent remote dev support, strong Chinese language ecosystem. Essential extensions: Chinese Language Pack, ESLint/Prettier (code quality), GitLens (Git supercharged), Thunder Client (API testing alternative Postman), Error Lens (inline error display), Material Icon Theme.

JetBrains IntelliJ IDEA Ultimate (Paid ~1500 RMB/year personal license): Worth every penny for Java/Spring Boot development. Reasons: Unmatched Java intelligence, Spring Boot integration out-of-box, database tools built-in, excellent refactoring capabilities. If do Java professionally pays for itself within first month.

Version Control and Collaboration

Git (Essential): No discussion needed - if not using version control stop everything learn Git today. GUI client: SourceTree (free visual good beginners) or GitKraken (beautiful UI free non-commercial). Command-line lovers: lazygit (terminal UI for Git - game-changer for efficient workflow).

Gitee vs GitHub: For 益阳 projects Gitee offers faster domestic access speed, integrated CI/CD, compliant data residency (data stays China). GitHub preferable for open-source targeting global audience or teams invested in GitHub ecosystem.

API Development Testing

Thunder Client (VS Code Extension Free): Lightweight alternative Postman. Runs inside VS Code no separate app. Collections environments variables - all essentials. For most API dev/testing needs replaces Postcard entirely.

Postman (Free tier generous): Gold standard comprehensive API testing. Complex collection/workflow testing, team collaboration on specs, API documentation generation, mock server for frontend dev. Free tier covers individual needs comfortably.

Database Tools

DBeaver (Free Open Source): Universal DB client supporting MySQL PostgreSQL Oracle SQL Server MongoDB Redis and dozens more. Features: SQL editor autocomplete, data editor, ER diagrams, query plan viz, export/import. Replaces need for multiple DB-specific tools. Go-to recommendation for all DB work.

RedisInsight (Free by Redis Labs): Best Redis GUI client. Visualizes data structures, monitors perf, provides CLI access. Essential if work with Redis regularly.

Container and DevOps

Portainer (Free self-hosted): Web UI for Docker management. Visual container management stack deploy user access control. Great for teams wanting Docker power without CLI expertise.
