Hoppscotch vs Yaak

Hoppscotch is a collaborative, open-source platform for creating, testing, documenting and sharing APIs. Its client supports HTTP, GraphQL, WebSocket, Socket.IO, MQTT and Server-Sent Events. Testing tools include pre-request scripts, post-request tests, environment variables, request history and collection runners. Teams can use shared workspaces, access-level roles and real-time collaboration, and the platform can be deployed on their own servers. Users can migrate from Postman, Insomnia and cURL, then generate code snippets in various languages and frameworks. Hoppscotch describes its data storage as local-first and says it has no tracking, analytics or ads. The free plan includes REST, GraphQL and realtime API testing, a personal workspace, collections and environments, scripts and tests, a collection runner and community support. Organization is $6 a month when billed annually. Business is $6 per user/month billed annually, while Enterprise is $11 per user/month billed annually. Enterprise includes identity and access management, audit logs and priority Slack Connect support. Hoppscotch supports more than 30 languages and is listed for API, Linux, macOS, self-hosted, web and Windows.

Yaak is a local-first desktop API client for sending requests, debugging APIs, and collaborating through Git. It runs on Linux, macOS, and Windows, and supports HTTP/REST, GraphQL, gRPC, WebSocket, and server-sent events. Users can arrange requests in workspaces and folders, switch environments, and reuse authentication and variables. Directory sync stores requests, folders, and environments as individual YAML files for Git workflows.

Yaak imports work from Postman, Insomnia, Bruno, OpenAPI, and curl. Plugins support authentication, importers, and template functions, with a 1Password plugin for retrieving passwords. The desktop app stores data locally and sends API requests directly to chosen servers; it has no built-in analytics or tracking. Optional workspace secret encryption uses XChaCha20-Poly1305, with the master key protected by the operating system keychain. Free use is for personal purposes; commercial use requires a license. Individual Annual costs $79 a year, and a 30-day trial is available.
