HttpStatus.com

HttpStatus is an API testing, monitoring, and developer tools platform built for modern development workflows. With over 700 free browser-based tools, it covers everything developers need — from JSON formatting and JWT decoding to SSL certificate checking, CORS debugging, OpenAPI validation, and uptime monitoring.

The platform is organized into specialized hubs: JSON, Regex, Cron, Base64, URL, Hash, UUID, YAML, Timestamp, JWT, HTTP, Security, and more. Each hub contains focused tools that run entirely in the browser — no installs, no signups, no data leaving your device.

Beyond individual tools, HttpStatus offers full-featured capabilities for API development teams: mock servers for frontend development, chaos engineering for resilience testing, automation workflows with Postman collection import, webhook capture and inspection, distributed tracing analysis, and multi-region uptime monitoring with alert channels and public status pages.

The platform recently launched its MCP Server — 24 AI-callable tools accessible from Claude, Cursor, ChatGPT, Windsurf, and any MCP-compatible client. Developers can now create API mocks, run security scans, check SSL certificates, validate OpenAPI specs, debug CORS issues, and set up monitors without leaving their AI assistant. One-line setup with OAuth2 authentication.

HttpStatus serves thousands of developers worldwide. The MCP server is published on the official MCP Registry and listed on Smithery, Glama, Cursor Directory, mcp.so, and npm.
