Practical tools for real developer workflows
CodeDevForge is not a link directory. Each tool solves a specific problem — comparing configs, exploring JSON paths, visualizing Java streams, validating schemas, or converting API formats — with guides and FAQs on every page so you know exactly when and how to use it.
JSON & data tools
Path finder, schema validator, format converters, and diff utilities for API payloads and config files.
JSON Path Finder →Config & DevOps
Diff .env and YAML, split Spring profiles, generate Docker Compose and Kubernetes snippets with security hints.
Config Studio →Java & Spring Boot
Stream visualizer, entity generators, migration assistant, and annotation helpers for everyday backend work.
Streams Visualizer →Everyday utilities
Diff checker, cURL converter, string utils, HTTP status reference, and minifiers — fast and browser-based.
