Why Use Our Developer Tools?
Introduction
- Browser-based utilities for formatting, validating, encoding, and inspecting data without sending payloads to a server.
- Designed for quick copy/paste workflows so you can debug payloads during reviews or incidents.
- Consistent UI and output formatting to reduce cognitive load across tools.
- Privacy-by-default: keeps tokens, secrets, and customer data local.
When to Use
- Format/Minify/Validate JSON before committing or responding to API clients.
- Base64/URL encode-decode when crafting headers, webhooks, or debugging integrations.
- Hash/UUID/Timestamp tools for IDs, fixtures, and reproducible test data.
- Regex tester for quick pattern checks; CSV/XML formatters for log or data cleanup.
How to Choose the Right Tool
- Use Validator for schema sanity; Formatter for readability; Minifier for payload size tests.
- Pick Hash Generator for checksums; use JSON-based signing elsewhere for security contexts.
- Timestamp Converter for epoch/human swaps; keep timezone awareness in mind.
- Regex Tester for quick tries; avoid embedding overly complex patterns in production without review.
Tips for Better Results
- Never paste production secrets into third-party sites; these tools run locally to stay safe.
- Keep sample payloads small; large blobs are harder to inspect and can mask edge cases.
- Add comments in commit messages about transformations done to payloads for traceability.
- Validate before shipping—catch malformed JSON/CSV early to prevent runtime failures.
Common Mistakes to Avoid
- Confusing encode vs decode paths (Base64/URL); double-check direction before sending payloads.
- Using hashes as a security substitute for signatures; hashes alone do not provide authenticity.
- Forgetting timezone context in timestamp conversions; specify UTC vs local when sharing results.
- Pasting production secrets into external tools; rely on these local utilities instead.
- Validating only happy-path JSON; include edge cases like nulls, empty arrays, and unexpected types.
