Top Recommended Replacements
Caido
FREETop Modern / Lightweight Alternative
Why we like it
Built in Rust for extreme performance and low RAM usage; modern, intuitive UI; native project management; much faster than Burp for manual proxy tasks; completely portable.
Keep in mind
Lacks the massive extension ecosystem (BApp Store) of Burp; the automated vulnerability scanner is still maturing compared to Burp's world-class engine.
OWASP ZAP (2.17.0)
FREEBest Professional Free Alternative
Why we like it
100% free and open-source; the 2025 updates (v2.17) introduced a new 'Insights' add-on and improved OAST support; fully scriptable; widely trusted for CI/CD integration.
Keep in mind
The user interface is functional but lacks the sleekness of Caido or the deep manual 'polish' of Burp Suite Pro; active scanning can sometimes be less thorough than Burp.
Beagle Security
Best AI-Driven Alternative
Why we like it
Focuses on automated, AI-powered DAST (Dynamic Application Security Testing); excellent for teams needing 'continuous' security without a dedicated pen-tester; provides highly developer-friendly remediation reports.
Keep in mind
Not a manual 'interception proxy' like Burp; less control for researchers who want to manually craft payloads.
Nuclei
FREEBest for Automated Scanning
Why we like it
Extremely fast template-based scanner; massive community-contributed library of vulnerability templates; ideal for large-scale reconnaissance and bug bounties.
Keep in mind
Lacks a graphical proxy/repeater interface; requires command-line proficiency; strictly for automated discovery.
Invicti (Acunetix)
Best Enterprise Scale DAST
Why we like it
Highly accurate automated scanning with very low false positives; features 'Proof-Based Scanning' which confirms vulnerabilities automatically; excellent for large corporate portfolios.
Keep in mind
Extremely expensive (enterprise pricing); lacks the manual 'tweaking' tools that professional pen-testers enjoy in Burp Suite Pro.
