Crusader vs Caido: choose the workflow, not the hype.
Caido is a fast, polished manual proxy with workflows, plugins, an API, and official Agent Skills. Crusader is a broader local security workstation that adds active proof, mobile and mTLS tooling, multi-identity replay, Beacon OAST, and native MCP over the same project.
The short answer
Choose Caido when you want a lightweight, browser-based manual proxy and its workflow/plugin ecosystem fits the engagement. Choose Crusader when you want proxy history to feed active scanning, Android and Frida work, mTLS identities, IDOR/BOLA actor replay, OAST, and an MCP-connected agent without assembling several separate tools.

This table distinguishes built-in workflows from things that can be assembled through plugins, APIs, Agent Skills, or external tooling.
| Workflow | Crusader | Caido |
|---|---|---|
| Intercepting proxy and history | Built in · local desktop project | Built in · Rust backend and browser UI |
| Manual replay and fuzzing | Repeater and Intruder-style attacks | Replay and Automate |
| Active vulnerability scanner | Built in · bounded proof replay and findings ledger | No comparable built-in scanner · workflows/plugins can automate tests |
| Mobile and Frida workflow | Integrated · APK analysis, device timeline, pinning and mTLS tooling | Proxy mobile traffic; use external mobile tooling for Frida and app analysis |
| Multi-identity authorization testing | Shadow Replay · compare one request across saved actors | Manual replay or custom workflow/plugin logic |
| Out-of-band testing | Beacon OAST · hosted or self-hosted DNS, HTTP, and SMTP callbacks | Use plugins, workflows, or an external OAST service |
| Agent and AI integration | Native MCP server + Agent Skills over scoped local project tools | Official Agent Skills backed by Client SDK and API coverage |
| Extensibility | Hot-reload JavaScript extensions, CLI, MCP, and advanced plugin APIs | JavaScript plugins, visual Workflows, SDK, and API |
| Project migration | Imports Caido, Burp, HAR, and SAZ | Standard import/export support varies by format |
| Collaboration | Squad and Team modes with redacted shared state and roles | Team plans and shared instances |
| Platform fit | Windows and Debian/Ubuntu Linux; macOS pending | Cross-platform browser UI with local or remote backend options |
| Pricing | Free tier; Hunter Pro $499/year | See current Caido pricing |
Which one should you install?
Choose Crusader when
- You test Android apps, certificate pinning, or mTLS.
- You repeatedly compare requests across users, roles, tenants, or organizations.
- You want a built-in scanner and OAST proof chain, not only manual replay.
- You want an agent to use native MCP tools over local project evidence.
- You need to import existing Burp or Caido projects without abandoning prior traffic.
Choose Caido when
- Your priority is a fast, focused manual proxy with a browser interface.
- You already rely on Caido's Workflows or plugin ecosystem.
- You want official Agent Skills backed by broad API coverage.
- You need macOS support today.
- You do not need integrated mobile, active scanner, identity replay, or OAST workflows.

Crusader vs Caido FAQ
Is Crusader a Caido alternative?
Yes. Both cover modern proxy, history, replay, automation, plugins, and free-tier workflows. Crusader is positioned as a broader workstation by integrating active scanning, mobile and mTLS testing, identity-aware replay, OAST, reporting, CLI automation, and native MCP.
Does Caido support AI agents?
Yes. Caido publishes official Agent Skills backed by its Client SDK and API. Crusader's distinction is not that Caido lacks agents; it is that Crusader exposes a native MCP server over the same local project used by proxy history, identities, findings, Beacon, and proof workflows.
Which tool is better for mobile application testing?
Crusader is more integrated when the engagement needs APK analysis, Frida-assisted certificate-pinning work, client-certificate mTLS, and captured traffic in one project. Caido can proxy mobile traffic while external tools handle those specialized tasks.
Can Crusader import a Caido project?
Yes. Crusader imports Caido projects alongside Burp project files, HAR, and Fiddler SAZ. The original source file remains untouched.

The free tier requires no account or card. Import a Caido or Burp project, replay one useful request, and keep the tool that saves you more time.
