Burp Suite
Deep legacy toolkit
Strong proxy, scanner, Attacker, Collaborator, extensions, and enterprise workflow coverage.
Competitive matrix
Burp depth. Caido speed. Interceptor local-first control.
Interceptor is positioned as a complete desktop testing proxy: the core workflows security testers expect from Burp Suite and Caido, plus API surface modeling, protocol diagnostics, evidence workflow, ergonomic request/response review, local or self-hosted OAST options, packet capture, and privacy controls built in.
Interceptor
Unified local-first workspace
Combines capture, API modeling, replay, active/passive analysis, diagnostics, reports, evidence, packet capture, hardened HTTP/2 and HTTP/3 protocol handling, request/response review ergonomics, and strict local control.
Caido
Modern collaboration UX
Fast browser-oriented workflow with Intercept, Replay, Automate, HTTPQL, Workflows, Assistant, Plugins, and Sitemap.
Feature-by-feature
One table. Three columns. Clear coverage.

Interceptor-only angle
What Interceptor adds beyond a merged Burp + Caido workflow.
These are not just checkbox equivalents. They are product boundaries and workflow choices designed for controlled, authorized testing environments.
Local-only OAST
Callback handling is loopback-scoped and opt-in, so blind testing stays under explicit operator control.
Network diagnostics
DNS timing, TCP connects, upstream proxy chaining, TLS handshake metadata, byte counters, and close reasons sit next to HTTP evidence.
Packet capture evidence
Proxy-mirror records, optional native PCAP capture, PCAPNG output, and rotating disk capture support network-level investigation.
Evidence-first workflow
Evidence board, report editor, findings lifecycle, raw exports, and project health views keep assessment output connected to captured traffic.
Modern protocol awareness
HTTP/2 direct proxy, h2c replay, HTTP/3, QPACK, MASQUE, WebTransport, ECH, HTTPS/SVCB, Alt-Svc, and RFC coverage are surfaced as first-class diagnostic context.
Review ergonomics
Search bars, syntax highlighting, invisible-character display, line numbers, safe HTML rendering, History placement, persisted splitters, layout switching, and Send To badges reduce context loss.
Safety defaults
TLS MITM is opt-in, CA trust is never installed automatically, active tooling is scope-aware, and proxy-side edits are auditable.
Methodology
Based on public product documentation.
This matrix is a marketing comparison of feature families, not a legal certification of parity. Burp and Caido capabilities are summarized from publicly documented product pages and docs; Interceptor capabilities are taken from the local feature map and product scope.
