Caido vs Burp Suite Professional: 2026 Comparison
Caido is a free penetration testing tool. Burp Suite Professional is a commercial penetration testing tool by PortSwigger Ltd.. Compare features, ratings, integrations, and community reviews side by side to find the best penetration testing fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
Solo penetration testers and small AppSec teams will move faster with Caido because it strips away the UI bloat that slows down manual web testing; you get request interception, fuzzing, and scanning without the enterprise overhead that makes Burp Suite feel like piloting a cargo ship. The free pricing eliminates procurement friction entirely, which matters when you're justifying tooling spend to finance. Skip this if you need SAST integration, collaborative workspace management for large teams, or NIST Respond capabilities like automated remediation workflows; Caido is built for hands-on auditing, not orchestrated enterprise remediation.
Security teams responsible for web application penetration testing will get the most from Burp Suite Professional because its manual testing workflow is genuinely faster than competitors when you need to find logic flaws and authentication bypasses that automated scanners miss. The platform covers ID.RA and PR.PS functions across both on-premises and cloud deployments, and PortSwigger's 299-person team maintains the strongest passive scanning library in the category. Skip this if your team lacks dedicated web security engineers or if you need a tool that also handles API fuzzing and mobile testing equally well; Burp's mobile support lags, and the learning curve punishes casual users.
