Reqable

Reqable is an HTTP traffic debugging and API testing tool for desktop and mobile, best suited to developers and other technical professionals who need to inspect requests and work with API collections. Its main strength is the combination of broad protocol coverage and request editing; the trade-off is a CA certificate requirement for API debugging and a mobile app without the desktop app’s editing and scripting tools.

Overview

Reqable brings traffic analysis and API testing into one cross-platform workflow. Its debugging proxy handles HTTP/1.x and HTTP/2, WebSocket, several proxy types and TLS 1.1 through 1.3, while API testing also supports HTTP/3 (QUIC) and Server-Sent Events. That range suits work across varied network traffic, though installing a CA certificate for API debugging adds a setup requirement.

API collections can be imported from Postman, Swagger, Insomnia, Hoppscotch, ApiFox, ApiPost, RapidAPI (Paw), cURL and HAR. Collections remain local when signed out; signing in enables cloud storage and syncing across devices. That gives individuals a local option and teams a route to keep collections aligned across devices.

Key features

• Traffic inspection and replay: The proxy supports HTTP/1.x and HTTP/2, WebSocket and HTTP, HTTPS, SOCKS4, SOCKS4a and SOCKS5 proxies, with TLS 1.1–1.3. WebSocket inspection and traffic replay add useful tools for investigating how requests and responses behave.
• API testing: Reqable handles HTTP/1.1, HTTP/2, HTTP/3 (QUIC), WebSocket and Server-Sent Events. This makes it a flexible choice when API work includes more than conventional HTTP requests.
• Editing and scripting: Request rewriting, breakpoints, response modification and Python scripts for processing request or response data let users intervene in traffic rather than only observe it. Proxy chaining is also supported.
• Collection migration: Imports from nine collection and request formats reduce the need to rebuild existing API work when moving to Reqable.
• Mobile-to-desktop forwarding: The mobile app can forward traffic to the desktop app through a VPN service, avoiding Wi-Fi proxy configuration. However, rewrite, breakpoint and script features are absent from the mobile app itself, so users who need those capabilities must use desktop.

Pricing

The Community edition is free and may be used commercially, including in business scenarios. It allows one device, 100MB of storage and three rules each for rewrite, script, breakpoint, gateway and mirror. Those caps make it a practical starting point or a fit for limited personal workflows, but constrain users managing multiple devices or larger collections.

Premium costs $49.90 a year and supports up to six devices, 1GB of storage, all features and priority technical support. It is the clearer fit for regular cross-device use or users who outgrow Community’s storage and rule limits. Community support is included with the free plan; Premium adds priority technical support by email.

Enterprise has custom pricing and includes unlimited devices, team collaboration, private deployment and customized feature development. It is aimed at organizations needing deployment or collaboration options beyond an individual plan; support is by email and Discord.

Platforms

Reqable is available for Android, iOS, Linux, macOS and Windows. Linux downloads are listed for x86_64 and require GTK 3.0. The mobile apps extend traffic forwarding, but desktop is necessary for the rewriting, breakpoints and scripting omitted from mobile.

Who it's for

Reqable is intended for professionals in development, testing, networking, security, web scraping and related engineering work, or people using it under qualified guidance. It is especially suited to users who need both traffic inspection and API testing, want to import existing collections, or need scripting and request intervention. It is a weaker fit for mobile-only users who need those editing tools directly on their device, and for anyone unwilling to install a CA certificate for API debugging.

Pros and cons

• Pro: Broad proxy and API protocol support, including WebSocket, HTTP/3 and Server-Sent Events, covers varied debugging and testing workflows.
• Pro: Request rewriting, response modification, breakpoints and Python scripting support active traffic debugging, not just inspection.
• Pro: Commercial use is allowed on the free Community plan, and imports cover common collection formats alongside cURL and HAR.
• Con: Community is limited to one device, 100MB and three of each listed rule type, which may be restrictive for ongoing or multi-device work.
• Con: API debugging requires a CA certificate, and mobile users must switch to desktop for rewrite, breakpoint and script features.

Alternatives

For a broader comparison, browse Web Debugging Proxies. HTTP Toolkit is worth comparing if its free Hobbyist plan’s traffic interception, manual request and response breakpoints, and built-in HTTP client tools fit the workflow. Moni Proxy may suit users whose needs fit its free plan’s single active mock, rewrite and breakpoint rule, limited DNS and ignore-host rules, and daily Compose-request allowance. Fluxzy is an option for personal use on its free Community Edition, which includes all features and adds an x-fluxzy-community header.

NetworkSpy is another freemium alternative. Probe is another freemium option. mitmproxy is a free and open-source interactive HTTPS proxy. ProxyHawk is a freemium alternative. Rockxy is another option.

Verdict

Its free commercial plan is useful for trying or maintaining a modest workflow, while Premium’s extra devices, storage and unlocked features suit heavier use. Look elsewhere if you need the full editing toolkit on mobile or cannot accommodate the CA certificate requirement.
