Caido vs Burp Suite 2026: Full Comparison
Last Updated: May 2026
Bug Bounty & Offensive Security · Web Security Proxy
Caido is an emerging web security proxy built by former HackerOne researchers, positioning itself as a modern performance-focused alternative to Burp Suite. Burp Suite, developed by PortSwigger, has been the de facto standard for web application penetration testing for over 15 years, with a massive extension ecosystem, mature feature set, and active community. Caido's key differentiators are its Rust-based performance, cleaner modern UI, collaborative features, and more affordable pricing — particularly attractive to bug bounty hunters and security researchers. Burp Suite's advantages are its maturity, 1,000+ BApp Store extensions, and its automated Scanner available in Pro and Enterprise editions. This comparison examines whether Caido's momentum in 2026 makes it a serious contender for Burp Suite's crown, and which tool is right for your web security workflow.

Our Verdict
Burp Suite wins on feature maturity and ecosystem depth; Caido wins on performance, modern UX, and price for bug bounty hunters.
Core Proxy Features: Both tools offer intercepting proxy, HTTP history, replay, and scope management. Burp Suite's Repeater, Intruder, Decoder, and Comparer modules are mature and deeply integrated. Caido's Replay and Automate modules cover similar ground with a cleaner interface, though with fewer advanced options at this stage of its development cycle.
Scanner & Automation: Burp Suite Pro's Scanner automatically discovers web vulnerabilities including OWASP Top 10 issues, SSRF, and injection flaws. Caido currently lacks an equivalent automated scanner — a significant capability gap for teams that rely on Burp's passive and active scanning. This single difference is the primary reason most professional teams maintain Burp Suite Pro subscriptions.
Extensions & Ecosystem: Burp Suite's BApp Store contains 1,000+ extensions enabling custom authentication handlers, scanners, and integrations with tools like SQLMap and Turbo Intruder. Caido's plugin ecosystem is nascent — extensions exist but the selection is a fraction of Burp's mature library.
Pricing: Caido offers a generous free tier and pro plans starting around $99/year per user — significantly cheaper than Burp Suite Pro at $449/year. For self-taught security researchers and bug bounty hunters, Caido's pricing is a major draw that makes professional-grade tooling accessible.
Best For: Burp Suite Pro is the choice for professional penetration testers who need the full scanner, mature extensions, and industry-standard tooling recognized by clients. Caido is the choice for bug bounty hunters, developers learning web security, and teams wanting a fast modern proxy at lower cost. Many professionals use Caido for its UI and Burp for its scanner.
