What is Rogatio?

Rogatio is a local-first tool for creating, reviewing, and running browser request and response rules. It replaces a handful of ad-hoc Requestly workflows with one version-controlled .rogatio.json file, a CLI, and a Chrome extension. The repository file is canonical — moving changes between it and the browser requires an explicit import or export.

Why teams choose Rogatio

One source of truth

A single version-controlled .rogatio.json describes every group and rule, so changes are reviewable, diffable, and revertible like any other code.

Runs in the browser

Redirect, query, header, and mock rules execute entirely in Chrome — no proxy, no server, no round trips to a third party.

Local runtime, on demand

Response- and request-body rules use a device-local runtime that activates only when you explicitly start and connect it.

Safe by default

No accounts, hosted runtime, cloud sync, telemetry, or retained traffic history. Your traffic stays on your machine.

Test before you save

Dry-run any rule against a bounded batch of URLs offline to preview redirects and rewritten queries before committing.

Auditable & diffable

Because rules live in your repo, every change ships through the same pull request and review flow as the rest of your code.
