A free, local-first API client that stores everything as plain files.
No accounts. No cloud. No telemetry. Just your requests on your disk.

Most API clients lock your data in proprietary formats, require accounts, or gate features behind paywalls. Requii takes a different approach:
- File-based workspaces — Requests, folders, and environments are plain JSON files on disk. Back them up, version them with Git, or move them to another machine by copying a folder.
- AI & automation friendly — Because everything is a file, AI coding agents and scripts can read, create, and modify requests directly. No plugins or APIs needed.
- Copilot skill installer built in — Install the Requii Copilot CLI skill from inside the app (Windows/macOS) to bootstrap agent terminology and safe request execution workflow.
- Easy sharing — Export a workspace (or a selection) as a single JSON file. Share via Slack, email, or commit it to your repo.
- Flexible environments — Base environment + per-context overrides (dev, staging, production). Nested variables, cross-references, and interpolation everywhere.
- Built-in auth — OAuth2 (authorization code, client credentials, PKCE), Bearer tokens, and Basic auth. Configure once per environment.
- Smart code editor — Monaco-powered body editor with syntax highlighting, formatting, and autocomplete for JSON, XML, and more.
- Cancel in-flight requests — Abort running requests instantly with one click.
- Insomnia import — Migrate existing collections without manual recreation.
- Cross-platform — Windows, macOS, and Linux installers.
- Private & offline — No internet required, no telemetry, no data leaves your machine.

The repo includes a manually triggered workflow (.github/workflows/manual-builds.yml) that builds all platforms on native GitHub-hosted runners and publishes a GitHub Release with the artifacts.
On first launch, Requii creates a workspace in your app data directory. Requests are stored as individual JSON files, environments in environments.json. The format is simple and human-readable — you can edit files directly if needed.
