Developer Tools

Tokens, configs, encodings, and subnets — decoded locally

Every tool on this page runs client-side. That is not a marketing line — it is the whole point. Plenty of similar sites post your input to a backend "for processing," which is a real leak when the thing you pasted is a JWT carrying a live session ID or a kubeconfig holding cluster credentials. Here the parsing happens in your tab and the payload never crosses the network. For the surrounding context, see JWT storage tradeoffs, the kubeconfig context guide, and JSON vs YAML vs TOML.

Nothing leaves your browser

Tokens, kubeconfigs, and encoded payloads are parsed locally with the Web Crypto and text APIs your browser already ships. There is no upload step and no server-side log to leak later. Need something broader? Our resources list points to larger toolboxes.
