About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Insomnia is an Electron application for designing, debugging, and testing REST, GraphQL, gRPC, WebSocket, SSE, and other HTTP-compatible APIs. Its OpenAPI editor, test suites, collection runner, and Inso CLI connect interactive development with CI/CD.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Key features

Debug multiple API protocols from one client

REST and HTTP, GraphQL, gRPC, WebSocket, and SSE requests can be sent from shared workspaces with detailed request and response inspection.

Sources: [2]

Extend into OpenAPI design, testing, and CLI automation

A native OpenAPI editor and preview, test suites, a collection runner, and the Inso CLI support API design and CI workflows.

Sources: [2][3]

Best fit

Fits API projects that need a choice of local, Git, or cloud storage

Sensitive projects can stay in Local Vault, versioned projects can use Git, and collaborative projects can use Cloud Sync depending on the workflow.

Before adoption

Distinguish account-free usage from subscription features

The Scratch Pad works without an account, while Git Sync, unlimited collaboration, organizations, SAML, and OIDC are associated with paid plans.
