About PinStack

A free utility suite by apitestlab.org. Engineered by Abubakkar Sajid (https://abubakkar.dev).

Software engineers, API architects, and developers perform hundreds of micro-tasks every day: beautifying a messy SQL query, generating TypeScript types from an API response, inspecting a JSON Web Token (JWT) expiration date, or decoding a Base64 string.

Unfortunately, many existing online tools are filled with popups, require server-side requests that compromise sensitive API keys, or have sluggish page reloads.

PinStack.cc was created to solve this problem by providing a modern, lightning-fast developer workspace where you can "pin" your daily tool stack with 100% in-browser client-side privacy.

Our Core Commitments

Strict Local Privacy: We never transmit, store, or log your code, SQL queries, or JWT credentials.
Sub-Millisecond Execution: Built with Next.js 14 and pure client-side algorithms for instantaneous output.
Always Free: Zero paywalls, hidden limits, or forced registration.
