In their own words
Testfully
Testfully is an API testing and monitoring platform with web, desktop and browser extension options. Its client supports RESTful, GraphQL and XML APIs, with cloud or local offline storage. Testing tools include no-code response validation, contract testing, request chaining, folder runners and scripts; the CLI can run tests in CI/CD pipelines. Users can import data from Postman or Insomnia, and the product supports OpenAPI Specification.
Monitoring can reuse workspace requests, retain a history of runs and send alerts through email, SMS, Slack or PagerDuty. Teams can assign roles and control folder access. The free Developer Edition includes core features and commercial use, one offline and one cloud workspace, and up to five invited users per workspace. Offline workspaces can be used without an account. Team Edition costs $14 a month per user when billed annually; Enterprise Edition costs $29 a month per user when billed annually. Paid plans have a 14-day free trial enabled by contacting sales. Desktop apps support macOS 12 or later, Windows 10 or later (64-bit), and Ubuntu 20+ and compatible Linux distributions. Browser extensions are listed for Chrome, Firefox and Microsoft Edge; Safari is marked as coming soon. Testfully says it was made in Australia and is headquartered in Sydney.
Yaak
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.
