API Dash vs Insomnia
Both are alternatives to Postman. Here's how they stack up — verified facts, no spin.
Also searched as Insomnia vs API Dash — same comparison, one verdict.
API Dash
A fully offline, cross-platform FOSS API client, mobile included.
API Dash is a fully open-source, cross-platform API client built with Flutter that runs completely offline with no account, on desktop and mobile alike. It handles everyday REST and GraphQL workflows, imports collections, and can generate client code. It is the most sovereign option on this list in posture, though it is younger and less battle-tested than the others.
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.
