Insomnia, alternative Linux à Postman
Mis à jour le
Notre avis
Insomnia est une alternative open‑source puissante à Postman pour la plupart des tâches de développement d’API. Il gère efficacement les requêtes HTTP standard, les collections et le scripting. L’avantage principal est sa licence MIT et l’absence de dépendance cloud obligatoire, permettant des flux de travail entièrement locaux. Il est idéal pour les développeurs qui préfèrent les outils open‑source ou qui doivent éviter les niveaux d’abonnement de Postman. Cependant, si vous comptez fortement sur l’écosystème spécifique de Postman ou sur des fonctionnalités avancées de serveur mock, vous pourriez rencontrer quelques frictions. Pour un travail REST et GraphQL standard, c’est un remplacement direct et performant.
- Licence

- Note

Ce qui fonctionne pareil
- Supports sending arbitrary HTTP requests (GET, POST, PUT, DELETE) with full response inspection.
- Organizes requests into collections and folders for structured API management.
- Supports pre-request and test scripts using JavaScript for automation and validation.
- Handles various authentication methods including Basic, OAuth, and API keys.
- Cross-platform availability including native Linux support via AppImage or package managers.
Ce qui change
- Insomnia is fully open-source (MIT), whereas Postman is proprietary with freemium limitations.
- Insomnia includes native support for gRPC, WebSockets, and SSE alongside REST and GraphQL.
- Postman has a more mature mock server feature, while Insomnia's mock server is still in development or recently released.
- Insomnia uses its own collection format, requiring conversion for Postman JSON files.
- Postman offers a larger marketplace of plugins and integrations compared to Insomnia's smaller ecosystem.

Insomnia does not natively open Postman collection JSON files directly. You must use the built-in import feature to convert Postman v2.1 format JSON files into Insomnia's internal format. This process is generally reliable for standard collections but may require manual adjustment for complex environment variables or script dependencies. Exporting from Insomnia to Postman format is not natively supported, so you should keep your source of truth in Insomnia once migrated.
Passer de Postman à Insomnia, étape par étape
- Export your Postman collections as JSON files (v2.1 format).
- Open Insomnia on your Linux machine.
- Go to the Collections menu and select 'Import Data'.
- Choose the 'Postman' format and select your exported JSON files.
- Review the imported collections to ensure environments and variables were mapped correctly.
- Test a few requests to verify authentication and script behavior.

Does Insomnia work offline?
Yes. Insomnia is designed to work locally without an account. You can store all collections in the Local Vault and perform all API testing without an internet connection, unlike Postman which often pushes cloud sync.
Can I use Insomnia for GraphQL?
Yes, Insomnia has native GraphQL support, including schema introspection and query building, making it a solid choice for GraphQL API development alongside REST.
Is there a free tier with no limitations?
Yes, the entire application is free and open-source under the MIT license. There are no feature locks or subscription requirements for core functionality like collections, scripting, or local storage.
