Developer Tools
10 free tools available
ToolsBaba Developer Tools is a free suite of browser-based utilities for JSON formatting, encoding, decoding, hashing, UUID generation, regex testing, and JWT inspection. Engineers, QA analysts, educators, and technical writers use these helpers during debugging, integration testing, documentation, and incident response when speed and precision matter more than opening a full IDE.
Client-side execution keeps tokens, payloads, and sample data off third-party servers — a meaningful advantage compared with random online formatters that may log inputs. Paste webhook bodies, validate JSON, encode URI components, generate test UUIDs, or inspect JWT headers with transparent, reproducible behavior aligned to common specifications.
Whether you are onboarding junior developers, validating staging responses, or preparing course demonstrations, these tools reduce friction without API keys or paywalls. Explore the category below and combine utilities as your debugging session evolves from parsing to encoding to security review.
