Used For

• +**Manually copying login tokens between 50 different test requests** → Set up request chaining once, runs automatically in 2 minutes instead of 20
• +**Frontend team sitting idle waiting for backend connections** → Mock servers let both teams work in parallel, saves 1-2 weeks per project
• +**3am deployment failures from broken connections** → Automated test scripts catch issues before you deploy
• +Works offline with encrypted local storage - no cloud data leaks
• +Handles GraphQL, gRPC, and WebSockets that break other testing tools

Best For

• >Your team is drowning in manual copy-paste testing and auth tokens
• >Postman keeps crashing on your large projects
• >You need to test GraphQL and weird protocols that other tools don't handle

Not For

• -Non-technical teams — requires basic JavaScript knowledge for the good stuff
• -Companies not building software that connects to other tools
• -Teams wanting everything in the cloud — the best features are desktop-only

Pairs With

• *Postman (what most people migrate from when they hit performance walls)
• *GitHub Actions (where your automated tests run via Inso CLI during deployments)
• *Kong (since they bought Insomnia, works great for Kong gateway testing)
• *OpenAPI (imports your API specs directly instead of manual request building)
• *Slack (where your team gets notifications when automated tests fail at 3am)

The Catch

• !The free version is local-only — team sharing costs $5-15 per person monthly
• !Large Postman imports crash on the free tier, forcing upgrades
• !You'll need to learn some JavaScript scripting or you're just using an expensive URL tester

Bottom Line

Tests your software connections without the bloat — actually works when your internet doesn't.
