### Why adOmnia



Most API tools went the wrong way: they moved your requests, secrets, and history into someone else's cloud, put your team behind a login wall, and charged you monthly for it. adOmnia is the opposite bet — **one fast desktop app that does more than the cloud suites, while keeping everything on your machine.**



It replaces a whole shelf of tools:



> **Postman + Insomnia + Charles/Fiddler + browser DevTools + a database client + a SOAP/WSDL tool + a load tester + a secrets manager + a PDF signer** — collapsed into a single portable executable that never phones home.



Four things set it apart — and **no other tool combines all four**:



-  **Local-first, for real** — no account, no telemetry, no cloud sync. Your collections, secrets, and traffic never leave your disk. Workspaces are plain files, and a **built-in Git client** (visual commit graph, branch/merge, push/pull, conflict resolution) versions them without ever leaving the app.

-  **Browser debugging built in** — inspect and debug real web pages (network, console, JS debugger, DOM, storage) *inside* the same tool you test APIs with. No competitor does this.

-  **Enterprise & legacy as first-class citizens** — SOAP/WSDL with WS-Security, mTLS, PKCS#12/JKS, gRPC streaming, and **real eIDAS-grade PDF digital signatures** (TSA timestamping + LTV). The boring-but-critical stuff Postman ignores.

-  **Yours to extend** — WASM/JS plugins, importable skins, shareable templates, and 11 built-in themes.
