Introducing RequestBin Collaborator Plugin – A Modern Burp Collaborator Alternative for Web Security Testing

🧠 Why We Built It

Security researchers and developers rely heavily on Burp Collaborator for detecting Out-of-Band (OAST) vulnerabilities such as SSRF, blind XSS, and RCE callbacks.

However, Collaborator’s limitations—closed backend, limited control, and dependency on Burp Pro—have left many professionals searching for a more flexible, transparent, and cloud-integrated solution.

That’s why we’re introducing the RequestBin Collaborator Plugin — a free and modern Burp Collaborator alternative, designed for developers, penetration testers, and red teamers who want better control, visibility, and flexibility in their testing workflows.

🚀 What Is the RequestBin Collaborator Plugin?

The RequestBin Collaborator Plugin integrates directly into BurpSuite, providing a native experience similar to Burp Collaborator, but powered by RequestBin.net — the industry’s favorite HTTP/DNS debugging and OAST testing service.

🔑 Key Features

• 🛰️ Collaborator Alternative: Fully compatible with BurpSuite for OAST-based testing.
• ☁️ Cloud-powered backend: Use RequestBin.net as your OAST endpoint.
• 🧩 Custom OAST Servers: Add your own private RequestBin OAST server for red team and enterprise needs.
• 🔒 Privacy-first design: Secure communication, zero data loss, and customizable storage.
• 💻 Cross-platform: Works with BurpSuite Community and Professional editions.
• 🌐 Real-time interaction view: Monitor HTTP/DNS callbacks in your RequestBin dashboard.

⚙️ How It Works

1. Install the Plugin:
   Download the .jar file from the GitHub repository and load it via
   BurpSuite → Extender → Extensions → Add → Select JAR.
2. Connect to RequestBin:
   Create a new bin at requestbin.net and paste your unique endpoint into the plugin settings.
3. Start Testing:
   Use your RequestBin-powered Collaborator endpoint to detect SSRF, XSS, RCE, or DNS callbacks just like you would with Burp’s native Collaborator.

💡 Why It’s a Better Burp Collaborator Alternative

With RequestBin Collaborator, you get greater flexibility, instant cloud integration, and visibility into every request, making it an ideal alternative for professionals seeking deeper insight into out-of-band vulnerabilities.

🔐 Perfect for Security Professionals

This plugin is especially useful for:

• 🕵️ Penetration testers looking for real-time OAST callbacks.
• 🧑‍💻 Developers testing webhook integrations.
• 🧠 Red teams performing internal/external security assessments.
• 🧪 Researchers experimenting with SSRF or DNS exfiltration payloads.

What changed in 2026

The plugin described above still works the same way. On the RequestBin side, OOB capture covers HTTP, DNS, and SMTP callbacks in real time — useful for SSRF, blind XSS, blind SQLi, and DNS-exfiltration testing — with bulk export for pentest reporting. See the full comparison, including pricing against Burp Suite Professional, on the Burp Collaborator alternative page.

🧩 Final Thoughts

The RequestBin Collaborator Plugin brings the power of RequestBin’s HTTP/DNS testing engine directly into BurpSuite — providing a modern, extensible, and free alternative to Burp Collaborator.

If you’re looking for a Burp Collaborator alternative that offers:
✅ Cloud integration
✅ Transparent request tracking
✅ Custom OAST flexibility
✅ Developer-first experience

Then this plugin is for you.
