HTTiny

A tiny, focused HTTP client for the desktop.

Every request is performed by the Go process with net/http — no CORS wall, every header yours to set, and Esc cancels the socket rather than the interface.

What it does

  • Requests run in Go, not the webview

    net/http performs every request, so CORS never applies, User-Agent, Cookie, Host and Referer are yours to set, opaque responses are readable, and Esc cancels the Go context so the socket actually aborts.

  • A response viewer that covers 19 formats

    Syntax-highlighted text with a JSON tree, a CSV table, an event-stream reader and sandboxed HTML and Markdown previews — plus real viewers for images, audio, video, PDF, fonts and archives, whose bytes stay in the Go process and stream over an internal route instead of crossing into the webview as base64.

  • Code view across 14 targets

    Raw HTTP, curl, curl for PowerShell, HTTPie, wget, fetch, axios, requests, httpx, Go, Java, C#, Ruby and Rust — answered by the same code path that sends the request, quoted correctly for the shell or language it lands in, with credentials redactable before you paste.

  • Environments and {{variables}}

    Each collection owns its environments, and substitution covers the URL, the query, headers, params, the body and auth. Lock a variable and its value goes to the OS credential store instead of the workspace file.

  • Credentials are never in your files

    workspace.json holds collections, requests and environments — portable, diffable, hand-editable. Bearer tokens, basic-auth passwords and locked variables live in Credential Manager, Keychain or Secret Service, which is what makes the workspace file safe to copy or attach to a bug report.

  • Ctrl+K, and nothing to save

    A command palette that reaches across every collection, a windowed sidebar tree that stays responsive at thousands of requests, and tabs scoped to the collection you are in. Everything autosaves — no dirty flag, no “discard changes?” dialog.

Before you install

  • The binaries are not code-signed. On Windows, SmartScreen warns the first time you run the installer — choose More info, then Run anyway. On macOS, open the app with right-click then Open the first time; double-clicking it will be refused.
  • Linux needs GTK4 and WebKitGTK 6.0. That means Ubuntu 24.04 or newer, Debian 13 or newer, or Fedora 40 or newer. Older distributions will not start the app.
