Insomnia
Clean, fast API client with strong GraphQL and gRPC support.
What it is
Insomnia is a streamlined REST, GraphQL, gRPC and WebSocket client with environment management, a plugin system and the Inso CLI for running suites in CI. Kong maintains it. A local-vault mode addresses the offline and privacy concerns that pushed some teams away from cloud-first clients.
Best for
Where it is strong
- Noticeably faster and lighter than Postman for everyday request work.
- Best-in-class GraphQL and gRPC ergonomics.
- Design-first OpenAPI workflow with linting built in.
Where it falls short
- A forced-account change in 2023 damaged trust; check the current model before standardising on it.
- Test scripting is less capable than Postman's.
- Smaller ecosystem of shared collections.
Pricing
From $12 per user/month (Pro; ~17% off billed annually)
Free tierFree tier: Essentials is free for up to 3 users, including local and cloud projects, CLI and 1,000 mock requests a month.
What drives the bill: Free for small teams; Pro lifts the user cap and adds RBAC, and Enterprise at $45 per user/month adds SSO/SCIM and Kong Konnect integration.
