Stellarium
Explorer.

Group requests into collections and folders inside a workspace. Open as many requests as you like in tabs, and save with ⌘S.

A workspace is just a folder on your disk. Each request is a .rqs file holding its RequestScript, next to a small .toml file with its name and settings. That means you can check a workspace into git and share it with your team. If you edit the files somewhere else, the app picks up the changes right away.

The editor reads the resource catalogue from your registry, so it knows every resource and function you can call. Type a dot after a resource and it suggests that resource's functions, along with their parameters, return types, descriptions and what each call costs.

• Completions for resources, functions and parameters. Press Ctrl Space to bring them up at any time.
• Hover docs for any resource or function in your script.
• Inline errors as you type, before you send anything to a node.

Each workspace, collection or request can choose two things: the registry it browses and completes from, and the node that runs its requests. Anything left empty is inherited. A request uses its own settings first, then its collection's, then its workspace's. That makes it easy to point one collection at a local node while the rest of the workspace talks to a shared one.

If your node needs an API key, add it here. Keys are kept in your system keychain and never written into your workspace files, so you can share a workspace without leaking them.

Press ⌘Enter and the request goes to your node, which calls each resource wherever it lives on the network. The response appears under the editor with its status and timing, formatted, with a raw view and a copy button. If a run takes too long, you can cancel it.

Each resource call comes back with a value and an error, so a call that fails doesn't fail the whole request. Your script decides what to do with it.

Stellarium Explorer is free and open source. Download the latest version for your computer from the releases page:

• macOS: Apple Silicon and Intel.
• Windows: 64-bit installer.
• Linux: AppImage, .deb and .rpm.

The app checks for new versions by itself and lets you know when one is ready. One click installs it and restarts the app.

You will need a registry to browse and a node to run requests against. To run your own node, follow the node guide. Want to build the app yourself? The README explains how.
