Built to keep sensitive work local.
DevPantry reduces exposure by running its utilities in the browser. This page explains the protections we rely on—and the limits you should understand before using any web application.
Security architecture · Last updated September 9, 2026
On-device execution
Tool inputs are processed by browser APIs instead of a DevPantry processing backend.
In-memory token work
JWT inspection and signing use browser memory and WebCrypto where supported.
No account surface
There is no account, password, or saved workspace to protect.
How the tools are isolated
Image tools use browser-side APIs, WebAssembly, and supported GPU capabilities to transform images locally. The JWT Decoder parses token data in browser memory and uses the Web Crypto API for supported cryptographic operations. Mock-data tools generate data in the active browser session.
DevPantry does not provide an API endpoint for uploading tool inputs. It also does not intentionally persist JWTs, images, custom schemas, or generated records in browser storage.
Security boundaries
Client-side processing protects data from being sent to DevPantry for tool execution. It cannot protect a compromised device, a malicious browser extension, copied output, or data shared with another website after export. Review sensitive output before saving or sharing it.
