OpenReq vs Thunder Client

OpenReq is a free, community-driven API testing application released under the MIT License. It runs as a self-hosted web application, a standalone desktop application, and a Windows client. HTTP, WebSocket, and GraphQL requests are supported as first-class request types, with visual test flows, collection runs, assertions, scripts, delays, conditions, loops, and reports. Automated test runs and API documentation are included, and API testing has no stated usage limits. Collections can become read-only public documentation links, optionally protected by passwords; viewers do not need accounts. OpenReq generates request code for cURL, Python, JavaScript, Go, Java, C#, and PHP. Integrations include Ollama, Postman, OpenAPI, raw cURL, Chrome, and Electron. Ollama can provide local AI features without a cloud API key or sending data away from the machine. The Windows desktop client is frontend-only and needs a separately hosted backend. Most endpoints use JWT bearer authentication, while local proxy setup uses HMAC-signed tokens.

Thunder Client is a REST API client that runs inside VS Code and JetBrains IDEs. It lets users build, test and share API collections with a team, and validate responses through a graphical interface without scripts. Requests and client data are stored locally, with no cloud sync; collections can also be saved to a Git repository for collaboration. Paid plans add WebSocket, SSE and gRPC support, as well as the CLI and CI/CD integration, where CI/CD collection runs are unlimited. Starter includes 250 local collection runs per user monthly, Business 500, and Enterprise unlimited. Enterprise also connects to Azure Key Vault and AWS Secrets Manager and can store environment values encrypted; Free, Starter and Business store those values in plain text. The extension collects basic anonymized telemetry, which can be disabled in VS Code settings. The maker says it does not collect personal or request data. A 14-day trial is available by request to business email addresses. Paid plans are billed annually per user: Starter is $3/user/mo, Business $7/user/mo and Enterprise $16/user/mo.
