The closest like-for-like Postman replacement: a polished desktop client with free Git Sync for small teams, but collaboration beyond 3 people is paid and some local data handling needs care.
What it is
Insomnia, owned by Kong, is a desktop API client for REST, GraphQL, gRPC, SOAP, WebSocket, Socket.IO and SSE, with collections, environments, pre-request and after-response scripts, a collection runner, OpenAPI design and linting, mock servers and the Inso CLI for CI. Each project chooses its storage: a local-only Scratch Pad that needs no login, a Local Vault, end-to-end encrypted Cloud Sync, or Git Sync to GitHub, GitLab or Bitbucket. It imports Postman v2 collections. Essentials is free, with Git Sync for up to 3 users and 1,000 mock requests a month; Pro is $12 per user a month ($10 billed yearly) with unlimited users and RBAC; Enterprise is $45 per user a month with SSO, SCIM and storage controls. Checked on insomnia.rest November 12, 2026.
Best for
- Teams that want a Postman-style app with Git or local storage
- Multi-protocol work: gRPC, WebSocket, SSE, GraphQL
- Small teams of up to 3 on a free plan
What we like
- Choose local, Git or end-to-end encrypted cloud storage per project
- Free Git Sync for up to 3 collaborators
- Wide protocol support plus OpenAPI design and mocks
What to watch
- Version 8 in 2023 forced an account and cloud sync; local and Git options returned, but the episode cost trust
- More than 3 Git Sync collaborators needs Pro at $10 to $12 per user a month
- Scratch Pad data is stored unencrypted on disk
- Postman scripts need manual review after import
