Local-first REST API client

A lightweight Postman alternative for local API testing

Most REST API clients are heavy, ask you to sign in, and sync your work to the cloud. TiefWise is the local-first alternative: free, under 8 MB, no account, and every request stored on your own machine.

Free · v1.2.0 · macOS & Windows

Choose TiefWise if…

  • You want to test APIs without creating an account
  • Your collections and API keys should stay on your machine, not a vendor cloud
  • You work offline, air-gapped, or in a compliance-sensitive environment
  • You want a tiny download (under 8 MB) that installs in seconds

A cloud-based client like Postman fits if…

  • Your team collaborates on shared collections in the cloud
  • You want a full platform with hosted workspaces and team governance
  • Cloud collaboration matters more than a small footprint

Those are genuinely good tools for cloud-collaboration workflows — TiefWise just solves a different problem: staying fast, private, and local.

Everything you actually use, none of the weight

Collections and folders, built-in auth, environments, request history, and response comparison — the day-to-day features most people open Postman for — in an app that starts fast and stays out of your way.

Where TiefWise isn't the right fit (yet)

  • ! Windows builds are x64 only — no ARM Windows build today.
  • ! It's local-first by design, so there's no built-in cloud collaboration or shared team workspaces.
  • ! TiefWise is at v1.2.0 and focused on REST/HTTP workflows.
