Charles

A web-debugging proxy that records and displays network requests and responses, letting you inspect headers, cookies, query strings and payloads; modify requests or responses for testing; simulate constrained network conditions; and watch live traffic flows to visualize request/response sequences. It’s aimed at developers, QA engineers, and testers working with web services and APIs who need to trace, debug, or manipulate network communication — useful for reproducing API errors, verifying authentication headers and cookie behavior, testing client resilience under poor network conditions, and validating backend handling without changing client code. A comparable free alternative is Godspeed, which offers request inspection, editing, and bandwidth simulation.

CocoaRestClient

CocoaRestClient is a free utility that helps developers and testers compose, send, and inspect HTTP and REST requests via a graphical interface, making it easier to exercise APIs during development and troubleshooting. It offers an intuitive UI for building and sending requests without the command line and is suitable for both quick checks and more detailed API debugging. You can edit raw request bodies, add custom headers and query parameters, and view responses in structured or raw form while checking HTTP status codes and monitoring response timings. Developers, QA engineers, and others working with web services can use it to validate endpoints, debug request/response issues, and iterate on API designs.

Charles Web Debugging Tool

A networking-focused debugging tool that captures HTTP/HTTPS traffic and exposes detailed request and response data, including headers, bodies, and timing. It supports throttling to simulate slow connections, breakpoints to pause and alter individual requests, live editing of requests and responses, session recording and replay, and broader protocol support for deeper troubleshooting. The interface organizes captured sessions with filtering, searching, grouping, and session export to simplify collaboration and documentation. Common uses include diagnosing failed or unexpected resources, testing client behavior under constrained bandwidth, reproducing intermittent bugs via recorded sessions, and mocking server responses during development to speed debugging and improve reliability.

Mockoon

Mockoon is a free tool for quickly creating mock APIs to simulate responses for testing and development. It offers an approachable interface for defining response bodies, headers, status codes, routes, and request handling, and lets you export and import configurations to share or reuse setups. By removing the need for a full backend, it helps teams prototype endpoints, validate client behavior against predictable responses, iterate faster, and reduce dependencies on external services during early testing.

LightProxy

LightProxy is a free, open-source web debugging proxy that provides a developer-friendly interface for inspecting HTTP/HTTPS traffic. It lets you capture requests and responses (payloads, headers, timing), intercept and modify incoming or outgoing messages, and record/replay sessions to reproduce intermittent issues, all through a straightforward GUI patterned after browser developer tools. It’s aimed at developers and QA engineers who need to reproduce bugs, test edge cases by altering headers/bodies/status codes, and trace multi-step client-server interactions. For users wanting alternatives, CheatSheet is a lightweight free option for basic request inspection, and some may consider trial utilities like IObit Advanced SystemCare for broader troubleshooting needs.

Requestly

Requestly is a developer and tester utility that intercepts and modifies HTTP requests and responses without changing backend code. It supports rewriting headers, redirecting URLs, replacing response payloads and status codes, blocking or filtering requests, and editing parameters and headers in real time via configurable rules and triggers. These rules can be scoped, organized, and toggled to create predictable, reproducible scenarios for debugging, API testing, mocking endpoints, injecting faults, and validating client behavior, which reduces development friction, speeds troubleshooting, and simplifies regression testing of edge cases.

Hoppscotch SelfHost

Hoppscotch API toolkit is a compact application for building, testing, and maintaining APIs, providing a unified environment to compose requests, inspect responses, and keep endpoint documentation organized. It lets you store projects locally and share configurations and request collections with teammates, tailor headers, query parameters, and payloads with flexible editing controls, and work with standard HTTP operations common to API workflows. Suited for individual engineers and small teams, it offers a clean, user-friendly interface and lightweight footprint to speed routine API tasks while helping teams maintain consistent request definitions and share work easily. A typical workflow is to create collections, add and configure requests, run tests and review responses, then export or share collections for feedback or handoffs.

HTTPS Everywhere

HTTPS Everywhere automatically upgrades many websites from insecure HTTP to encrypted HTTPS, helping prevent interception or tampering of web traffic. It protects communications such as logins and form submissions by prioritizing secure endpoints and reducing the chance that third parties can read or alter your data. The extension is low-maintenance and runs quietly once enabled, continually enforcing secure connections. It’s classed as an access-control/security tool; if you want broader protection, consider alternatives focused on malware scanning, full antivirus suites, or network/outbound-connection monitoring—choose based on whether you need a simple HTTPS enforcer or a more comprehensive security package.

IntelliJ HTTP Client CLI

A compact HTTP client for crafting and dispatching web requests and inspecting responses quickly, designed for fast request/response cycles when interacting with APIs. It supports common HTTP verbs (GET, POST, PUT, DELETE and others), simplifies request syntax by borrowing patterns from JetBrains HTTP tooling, and is offered free of charge. It's aimed at developers, QA specialists, and anyone testing or exploring web services, and is suitable for automating routine checks and integrating into development workflows.

Betwixt

Betwixt is a lightweight proxy that provides a live, graphical view of browser network activity, recording and displaying requests and responses with headers, payloads, status codes, and timing/throughput metrics for real-time analysis and easy navigation of captured sessions. It helps troubleshooting by enabling on-the-fly examination of network activity and correlating headers, payloads, and performance data to locate bottlenecks and speed iteration; Vezér is a free alternative offering a similar developer-focused network inspection experience.

Wombat

Wombat is a gRPC client that provides a graphical environment for crafting requests, inspecting responses, tracing message flows, handling protocol buffer schemas, composing payloads, and organizing connections and projects. It bundles a lightweight, protocol-aware toolset for defining and validating request/response structures and quickly connecting to service endpoints. Typical uses include diagnosing failing RPC calls, inspecting payloads and metadata, iterating on message definitions, and managing multiple service configurations. A suggested alternative is Shiba (free tier), which offers comparable functionality with a different workflow or integrations. Developers favor Wombat for its approachable interface and tools that speed routine gRPC tasks and reduce errors.

Restfox

Restfox is a free, offline-first HTTP client that lets you compose, save, and replay requests without a network, making it useful for developers and test engineers who need repeatable API tests, diagnostics, or to reproduce issues in a controlled environment. It’s designed to be compact and user-friendly to keep routine API work efficient. Key features include organizing requests into collections or folders for quick reuse, support for various request types, built-in response viewers and debugging tools to inspect payloads, headers, and status codes, and a minimalist interface that lowers the learning curve. An alternative to consider is CheatSheet Free.
