The API client your team has been waiting for

Beyond the basics

Import, environments and MCP

New in 1.3

Compare responses

The Compare button on the response panel shows what changed since the previous send: the body, the headers and the request itself, split or unified. Normalize JSON ignores key order and timestamps.

How comparison works →

Tetiva

v1.3.1

• MCP server →

  Agents and LLM tools call your collections over MCP.

• Environments & variables →

  Switch dev, stage, and prod without editing requests.

• New

  Import from other clients →

  Postman, Insomnia and Hoppscotch collections, OpenAPI specs and HAR files move over in a couple of clicks.

• Copy as →

  The menu next to Send copies the request as cURL, Python, Go, Java, C#, PHP or JavaScript.

• Response examples →

  Save a response as an example; it syncs along with the request.

• Cookies →

  The cookie jar keeps sessions between requests automatically.

• Workspaces

  Keep projects and teams apart without mixing collections.

• Keyboard-first →

  Send, switch tabs, find a request — without touching the mouse.

The desktop client is free and open source. The contents of collections, requests, environments and variables are encrypted at rest in the cloud (AES-256-GCM); the master key lives apart from the database.

Frequently asked questions

Is Tetiva free?

Yes. The desktop client is free and open-source under the MIT license. The cloud has a free tier (2 devices, 20 collections); Pro and Team are paid.

Do I need an account to use it?

No. The desktop app opens to an empty request and lets you send HTTP, gRPC, GraphQL or WebSocket calls without ever creating an account or signing in. An account is only required if you choose to connect to a sync server.

Does it phone home?

No analytics, no telemetry. On its own the client only checks for updates, at most once a day — a GET for the latest version number that carries the app version and OS, nothing about you or your requests — and downloads the new version when there is one. Both can be turned off in settings. Everything else is the calls you send. The source is on GitHub if you want to verify.

Can I import my Postman collections?

Yes. Postman v2.1 JSON exports import directly: folders, requests, headers, bodies, auth, descriptions and saved responses come across, and environments come in as separate files. Scripts come across when you tick Import scripts, though pm.* is only partly supported. Form-data files are picked again, and collection variables become an environment named after the collection; the migration guide lists the rest. Insomnia and Hoppscotch collections, OpenAPI specs and HAR files import too.

Is the sync server required?

No. Sync is fully optional. You can run Tetiva as a single-user desktop app indefinitely. When you do want sync, connect a workspace to Tetiva Cloud.

How does this compare to Bruno or Yaak?

Bruno and Yaak store collections as files and sync them through Git — great for version control, but there is no live sync: a teammate's changes arrive with the next pull. Tetiva takes a different path: SQLite locally + optional cloud sync with realtime updates, plus a built-in MCP server that lets AI agents manage your collections.

Is there a CLI?

Not yet. For AI agents, an MCP server is built into the app: Claude Code or Cursor connect to it and run your saved requests. A CLI for CI/CD pipelines (similar to Newman) is on the roadmap.
