Developer Tools
A premium developer platform, built by BizTechLab. Fast, free, no-signup utilities for the everyday work of writing software — with the same editorial depth and design standard as everything else on BizTechLab.
Not another tools directory. Part of BizTechLab.
Every tool here exists to be genuinely useful on its own — but it also lives one click away from the Opinion articles, Tech teardowns, and Research whitepapers that explain the “why” behind the “how.” Decode a JWT, then read our take on API security. Format a JSON payload, then dig into an architecture case study. No signup walls, no ads inside the editor, no dark patterns — just fast, dependable tools, built to the same standard as our writing.
Planned Tool Categories
JSON
Format, validate, compare, and transform JSON — the most universally needed developer utility.
JWT
Decode, verify, and generate JSON Web Tokens for debugging auth and session flows.
Encoding & Decoding
Base64, URL, HTML entity, hex, and other everyday text transformations.
Hash & Crypto
Hashing, HMAC, password strength, and secure random generation for security-conscious builds.
Text & String
Case conversion, counting, diffing, slugs, and everyday text manipulation.
Regex
Build, test, and understand regular expressions without the usual trial-and-error pain.
Time & Date
Timestamp, timezone, and cron conversions for backend and DevOps work.

Meta tags, favicons, robots.txt, and other 'make my site work' utilities.
SEO Tools
On-page SEO diagnostics and generators — built by a team that lives and dies by SEO.

Client-side image, QR code, and barcode utilities — nothing uploaded to a server.

Boilerplate generators for .gitignore, licenses, changelogs, and code formatting.
