Offline-first
Collections, environments and history live in a local SQLite database. Rocketly opens instantly and keeps working without a network.
Speaks Postman
Import Postman collections, environments and globals, OpenAPI, Insomnia or a cURL command. Scripts use the familiar pm.* API.
Sync on your terms
Sign in only if you want your work on every device. Secret values never leave your machine, and you can host the sync server yourself.
Variables
Hover a variable. See where it comes from.
Every {{variable}} is highlighted as you type. Hover one to see its value and whether it comes from globals, the collection or the active environment, then edit it right there.
Scripts & tests
Scripts and tests you already know.
Pre-request and post-response JavaScript runs in a sandbox with pm.test, chai-style expect, pm.sendRequest, CryptoJS and a console. Test results sit next to the response.
Runner & CLI
Run whole collections, locally or in CI.
Run a collection or folder with iterations, delays and a CSV or JSON data file, then export JSON, HTML or JUnit reports. The rocketly command runs the same pipeline in your CI.
rocketly run shop-api.json --env Dev --data users.csv --reporter junit
Import & export
Bring your collections with you.
Drop a Postman, OpenAPI, Insomnia or Rocketly file on the window, or paste a cURL command into the URL bar. Export back to Postman v2.1 whenever you like.
Sync
One workspace, every device.
With an optional account, workspaces, collections and environments sync in the background. Work offline and Rocketly catches up when you are back; conflicts are kept, so nothing is lost.
Your work stays yours.
Rocketly is built to run on your computer, not on someone else’s server.
No telemetry
No analytics, no usage tracking, no phoning home.
Secrets stay local
Variables marked secret are never sent to the sync server.
One local database
Everything is in a SQLite file you can back up and restore.
Self-hostable sync
Run the sync server on your own infrastructure with Docker.
