Altair GraphQL Client vs Hurl

Altair GraphQL Client is an IDE for running and debugging GraphQL queries, mutations and subscriptions. It formats queries, supports file uploads using the multipart specification, and can export query collections. Users can set environment variables for endpoints, headers and queries, then browse schema types and operations in a documentation explorer. Pre-request and post-request scripts and an extensible plugin system add customization options. Altair GraphQL Cloud provides centralized query management, collections, query versioning and shareable query URLs. Official integration packages include Express middleware, Koa middleware, a static build and a Gatsby plugin. The free Basic plan lists up to two team members and 20 queries; Pro costs $7.99 a month per user and lists unlimited team members, teams and queries. The client is available as a web app and on desktop platforms, including Linux, macOS and Windows, with extension and self-hosted options. The maker says the web app is for quick or one-time use, not full development, because it has limitations. Documentation warns that introspection can expose an API schema and that Content Security Policy support is beta.

Hurl is a command-line tool for running HTTP requests written in a plain-text format. It can fetch data or test HTTP sessions, including flows where later requests use values captured earlier. It can evaluate queries against response headers and bodies. Hurl works with HTML, REST, SOAP, GraphQL, XML, and JSON APIs, and examples cover assertions for status, headers, cookies, XPath, JSONPath, response duration, and SHA-256 body hashes. For CI/CD, it can produce text, JUnit, TAP, and HTML reports; its documentation covers GitHub Actions and GitLab CI/CD. The lightweight binary is written in Rust, with an HTTP engine powered by libcurl. Installation options include binaries or packages for Linux, macOS, and Windows, as well as Docker, Cargo, conda-forge, and npm. The precompiled Linux binary requires libc 2.35 or newer. Windows installation requires a separately installed Visual C++ Redistributable Package. Hurl is free under the Apache License, Version 2.0.
