Collaborative API tooling, encrypted by default

Your team's API workspace, encrypted end-to-end.

ReqBox is an API client built for teams: realtime collaboration and sandboxed pre-request & test scripts — with every request, header and secret encrypted on your device before it ever reaches our servers.

What ReqBox does today

No vaporware — every item below is shipped and working.

Encrypted on your device

Collections, requests, headers, bodies, environments and variables are encrypted on your device. Our server only stores and relays ciphertext it cannot read, so we couldn’t open your workspace even if we wanted to.

Realtime team sync

Edits from teammates show up live. Everyone on a workspace sees the same tree and the same requests as they change.

Environments & variables

Workspace, folder, collection and environment variables, with color-coded resolution so you always know where a value comes from.

Tests & scripts

A visual test builder for status, timing, header and JSON checks with no code, plus sandboxed scripts for anything more custom.

Import & export

Bring collections in from Postman, OpenAPI 3.x or a pasted cURL command, and export to Postman, OpenAPI or ReqBox’s own format.

Trash & restore

Deleted something by mistake? Restore it from the trash.

Plans

Pro belongs to a team, not to a person. You can be in as many Pro teams as you like, plus one Free team.

Free

To try ReqBox with your team

  • 1 workspace per team
  • Up to 2 members
  • 3 environments per workspace
  • Unlimited collections and requests
  • Realtime sync, encrypted end to end

Pro

Per team

For teams that need more room

  • 5 workspaces per team
  • Up to 10 members
  • 5 environments per workspace
  • Unlimited collections and requests
  • Realtime sync, encrypted end to end

Advanced roles, SSO and audit log: coming soon

The team owner pays with a Mercado Pago QR, monthly or yearly, and can extend it any time. If a team goes back to Free, nothing is deleted: extra workspaces become read-only.
