A DevFoundry product · Preview

A native desktop API client built for developers.

Professional desktop API workspaces. Local is available today. Git and Cloud providers are planned — equal peers in the product model, not requirements to get started.

Why Crucible

Professional desktop API workspaces — without the clutter.

A focused native client that stays out of your way. No account wall. Local ships in Preview; Git and Cloud are Planned providers.

Native desktop experience

A focused macOS app — not a browser tab pretending to be a workspace.

Local available today

Local workspaces ship in Preview: collections, environments, and history on your machine. No account required.

Fast request execution

Send, inspect, and iterate without waiting on a remote round-trip for day-to-day work.

Environments that stay clear

Base and active environments with secret references — visible where you need them.

A calm response viewer

Status, timing, headers, and body presentation built for long sessions.

Import from Insomnia

Bring an existing project and keep working — migration without a sales funnel.

Built for developers

Command palette, keyboard shortcuts, scratch requests, and diagnostics you control.

No account required

Download, open, create a workspace. Git and Cloud providers are Planned — not gatekeepers.

Roadmap

Planned — not available yet

Honest view of what’s next. Nothing below is available in the current Preview. Local, Cloud, and Git are equal workspace providers — only Local ships today.

Cloud provider

Planned

Optional synced workspaces when you choose a Cloud provider. Local, Cloud, and Git remain equal peers.

Git provider

Planned

Version workspaces alongside your repositories when you opt into a Git provider.

Additional importers

Planned

OpenAPI, Postman, and Bruno — marked Planned in-app until implemented.

Update system

Planned

In-app updates for Preview and Stable channels once publishing is established.

Windows

Planned

Native packaging and Gatekeeper-equivalent distribution for Windows.

Linux

Planned

Native packaging for Linux distributions after the macOS Preview path is solid.
