Schema as documentation
The introspected schema is parsed and browsable as a tree — types, arguments and descriptions — always at hand while you build.

The desktop client built only for GraphQL. Browse your schema as living docs, graft your query one level at a time with add Query / add Child, and send it across any number of endpoints.

Introduction
Purpose-built to remove the friction of using GraphQL in generic clients.
GalleonQL is a desktop client for developers who work with GraphQL APIs every day. It pulls in your schema over HTTP introspection, parses the shape of inputs and outputs, and lets you browse it as documentation while you build queries from that same schema.
Where generic REST clients bolt GraphQL on as an afterthought, GalleonQL is GraphQL-first. HTTP requests are issued from the Rust side (reqwest), so it is free of the browser's CORS limits and reaches any endpoint directly. Environments are orthogonal in the Postman sense, so one query works across every endpoint.
The interaction model is a "grow a tree" metaphor. Graft = grow a query by splicing on branches with add Query / add Child — a metaphor that runs through the entire UI.
01
Pull in the schema
Register an endpoint and introspection fetches the type catalog, expanded as documentation in the right pane.
02
Insert a root with add Query
From the schema's Query / Mutation fields, insert the root branch of your query.
03
Grow branches with + child
Expand one level at a time on object-typed branches. Graft recursively until the query has the shape you need.
04
Pick an environment and send
Compose "query × selected environment", send it CORS-free, and inspect the response as JSON tree / raw / headers.
Features
From schema to send — every tool made for GraphQL.
Everything here ships today. The staged builder, the orthogonal environment model, and CORS-free sending are the core.
Graft-style query builder
Insert a root with add Query, expand one level with + child. The ▼ lets you choose "leaf scalars only / all" just for that step.
add Query · add ChildSwitch across endpoints
Environments are orthogonal "connection profiles" (the Postman way). Queries stay environment-free; only the target changes between dev / stg / prod.
orthogonal envsAuth with method and secret split
The auth "method" (None / Bearer / Basic) is kept separate from the "secret". Tokens and passwords stay local to the environment and never travel in shares or exports.
auth: type · secretCORS-free HTTP sending
HTTP is always issued from Rust (reqwest), free of browser CORS. Inspect responses across JSON tree / raw / headers, with status and timing.
Rust · reqwestSQLite schema cache
The introspected schema is cached in local SQLite, keyed by endpoint URL. Instant on next launch; refresh only via the manual "⟳ re-fetch".

One project, free forever. Add a slot only when you grow.
When you add a project and have no free slot, you buy an extra slot. The price per slot steps down as you add more. It's a subscription — billed monthly for what you use.

From the 2nd project on, buy "extra slots" as a monthly subscription. The price steps down: 2nd ¥250 → 3rd ¥240 → 4th ¥220 → 5th and beyond ¥200 each.
Cancel anytime — your data stays. If you stop paying while running several projects, all data is kept, but only the first-slot project remains usable.

FAQ
FAQ
How does the billing cycle work?
Billing runs on a one-month cycle starting from your initial sign-up date, so you pay for usage in arrears. Even if you cancel partway through, you keep access for one month, and one month's charge is billed on the payment date.
I want to switch machines or use it on another computer
If you replace your machine or want to use your license key on a different computer, release the license key from the existing app, then register it again on the machine you want to use.
