Best Burp Suite Alternatives in 2026 (for Security Testers and Developers)
Burp Suite is the benchmark proxy interceptor for web security testing, but it is not the right tool for every job. Security testers look for free or lighter options, and developers often reach for Burp only because it is the best-known "intercept and modify requests" tool. This list covers both groups.
ZAP
Open-source intercepting proxy with active and passive scanning, fuzzing, scripting and strong CI automation. The closest free equivalent to Burp for security work.
ProxyCeptor
If you reached for Burp to change a response or force an error while building a feature, ProxyCeptor is faster: persistent rules in Chrome DevTools, JSON deep merge, delays and status codes, no certificates, and an SDK for Smart TVs. It is not a vulnerability scanner.
Caido
A newer web security toolkit with an intercepting proxy, replay and automation, designed to be lighter and faster than traditional Java-based tools.
mitmproxy
Terminal, web and headless modes, with a Python addon API for automated modification of traffic.
HTTP Toolkit
Open-source desktop proxy with automated interception of browsers, Android, Node.js and Docker, plus mocking rules.
Frequently asked questions
What is the best free alternative to Burp Suite?
For security testing, ZAP. For developers who only need to intercept and modify API traffic in the browser, ProxyCeptor.
Is Burp Suite Community edition enough?
For manual interception and Repeater, often yes. The scanner and advanced automation require Burp Suite Professional.
