Bruno vs Insomnia
Both are free/open-source alternatives to Postman. Here's how they stack up — verified facts, no spin.
Bruno
TOP PICKA fast, git-native API client that stores collections as plain files.
Bruno is an open-source desktop API client that keeps every request as a plain-text .bru file on your filesystem, so collections version-control in git right alongside the code they test. It runs entirely offline with no account required, imports existing Postman collections, and is notably lightweight and quick to start. The free core is fully featured for individuals and small teams; advanced Git, SSO, and org-scale management sit on paid Pro and Ultimate tiers.
Insomnia
A mature, multi-protocol API client with a fully local storage mode.
Insomnia is an open-source, cross-platform API client maintained by Kong, covering REST, GraphQL, gRPC, WebSocket, and SSE. Its Local Vault and Scratch Pad options keep collections 100% on your device, and Git Sync stores them in a repository you control, while optional Cloud Sync adds end-to-end-encrypted team collaboration. It is well-established and feature-rich, though most capabilities beyond the local Scratch Pad require a (free) account.
